We have been using the Sennheiser CC550 professional wired headsets for years with a range of phones, Nokia, SE, Iphone (you can buy different endplugs). But to my astonishment the sound from the microphone is crap with the S2. After extensive research we haven found out that this is a general problem with Samsung, Google/Samsung telephones and S2, no professional headset (call center type) that we or our supplier have tried (we tried a lot). We also checked the wiering scheme to exclude any "grounding" problem, and can't find a problem there either.
Anyone got a wired call center type headset to work?
I have done some reserach and it seems that the condensator microphones used in electronic headsets have to voltage standards (someting like 1,5 V and 2,3 V) - could it be that Samsung uses the lower voltage or someting.
To add on the burden the bluetooth implementation in S2 is crap (tried Plantronic Discovery - doesn't work at all and SE WM600 works but not very well and doesn't have a micrphone "boom".
Any suggestions?
I am using Plantronics Discovery everyday from the very first day I bought
my SGS2 without any problems whatsoever. I have still stock 2.3.3 fw on my
phone, plus the matching cf-root. Are you on stock fw as well, or have you
flashed a custom ROM - maybe this is to blame?
As for the wired headset issue in general, it is a fact the the Android
implementation (in general - regardless of manufacturer) is, to say the least,
mediocre. No wired headset with in-line remote works (i.e. volume control,
skip/forward, etc) without custom apps and ridiculous button press combinations.
Thanks four your reply. I have uppgraded a few orginal ROMs, currently on Cognition 1.6. The problem with Samsungs bluetooth stack on S2 seems to be widespread, we bouth the WM 600 as it seemed to have the least issues and it's headset sond is ok if not good (don't mix the headset profile up with the A2DP bluethooth "music" profile which is not engaged in hedset mode) . The CM7 ROM seems to have sorted out the bluetooth stack problem, but have other issues. Our wired headset problem is not related to in line controll buttons (or anything with media playback for that matter). This is another aspect of the headset functionality that we don't use e.g. the CC550 don't even have any buttons - as it is a "call center" headset. Our focus is pure "talk" sound quality - and particular microphone (outgoing) sound quality as the CC550 (and other wired headsets) relays the speaker at the other end normally (i.e. good). As a sidenote maybee Android 4 supports USB headsets, it seems possible to connect a DACT anyways, this would solve our issue /Regards voz
Don't know if you have the same problem as I do; here is what happens with my microphone issues. Maybe related?
When using any wired headset, everybody will complain that I am "too loud". Not just painful volume, but distorted. At first I thought it had to do with the frequency of my voice or something, but apparently people can hear my car radio at a volume so low I have forgotten that it is on.
Another thing I have noticed is when I am using headphones with a microphone (not necessarily talking on the phone) I hear buzzing noises, usually when interacting with the phone. For some reason when I use Twitter it's really bad. Once, while I was on the phone somebody said they could hear it too.
My only solution to the mic-gain issue was to enter service menu and lower mic gain levels, of course when I reboot settings are lost and to be honest when I forget to re-enter them, my friends and coworkers take the opportunity to ream me out.

If anybody knows another fix, or way to make an adjustment permanent I would love to know.
Interesting, I cranked it up to 100, see how it goes. There are some other interesting settings, eg. Tx Gain - do you know what that is for?

My value for that and the 2 things before it are "0x6132"
I know this service menu isn't really meant for end-users, but it would be great if there was a little more documentation we could find regarding these values and what it all means.
[4]dst speech tx volume: tried 100 - increased the volume, tried 60 decreased the voluem - so it does work. However, the problem with the Sennheiser cc550 is that the Galaxy S2 changes the frequency response or something - so the volume is actually ok with the default setting at 88, but the sound comes out "high pitched" at the other end. To me it seems like the microphone in the headset is not feed properly from the handset. For an article on the subject see http://www.hobby-hour.com/electronics/computer_microphone.php

Well, I was unsure if I should post this under one of the old posts, but I decided to start it as a new clean post...
Many are having problem with "hissing" noise, joint-stereo and low bitrate(or bitpool). For my sake, I've tried "fit4cat - Hermes Tweaker", "Sleuth255 A2DP fix" and several other methods, but without beeing able to get the soundquality I want from my headset.
Now, this is what worked for me after tweaking around with the registry a while, and endless pairing sessions
Download a registry editor(I use PHM, http://www.phm.lu/Products/PocketPC/RegEdit/ <- Download the PocketPC 2002/2003 ARM/PXA)
1: Turn off bluethooth on the Trinity
2: Unpair the Trinity with the headset(Delete the headset from the list!)
3: Change the following registry settings:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2 DP\Settings
MaxSupportedBitPool=80
MinSupportedBitPool=40 (or more if you want)
(if these arn't there, add them!)
And DELETE:
UseJointStereo = 0/1 (depending on whatever you have put there before)
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev]
Priority256=149
(let the rest be as it is)
4: Reboot
5: Now, DO NOT use the headset for direct pairing!(since you've already added your phone to the headset, pressing a button on it will useually pair it back with the Trinity) <- This seems to be the function that triggers the sound-problem...
Instead, set the headset in visible mode, and use the trinity to pair(search for new devices), when you find the headset and pair it, you will hear the pairing-sound from the trinity-speaker, and NOT the headset.
Now you can enjoy high quality stereo sound without any disturbance
But, the problem comes when you turn off your Trinity, or the headset. If you try to connect the headset and the phone by using the connectbutton/playbutton on the headset, it will pair, but this time you will hear the pairing sound in the headset, and then you have all your problems back... So then you have to turn of bluethooth, delete the headset from the trinity, and add it back once again by turing the headset in visible mode again.
So the solution to this, is to go to the device list on the trinity after you have lost connection with the headset(this is if you have turned of the trinity or the headset), and hold the stylus on it and choose "Use as wirelss stereo" and "use as handsfree"...
Thanks to all of you guys here who have posted solutions to the A2DP problems And if anyone have suggestions to other values that are better fit then the onces I've supplied, share them with us
And if all of this have been posted in another thread that I've missed out, the moderators are free to delete this one
Good grief, I can only imagine how many times you had to pair the headset before you noticed what was going on LOL, hope you didn't turn blue in the face
I imagine a ROM update could fix this problem.

Hehe! The thing that made me going was that I was able to get perfect sound once or twice, and since I made it work those few times I just had to find out what I actually did that made this work (And paying 175$ for the headset also keept me fueled for a while ) hehe!
I think I've used about 5-6 hours total these two days sitting pairing, adjusting settings, rebooting(ARGH!), untill I found out that the problem actually occurs when you use the headset to pair instead of the trinity
I don't understand what is it with bluetooth stereo:
quality is not good enough to listen to music 64 kbps... no bass, no medium, nothing just a hiss.
and plus you get 80% cpu (with a 400Mhz...), just to encode this crappy 64 kbps.
Yes exactly for all people having so many skipping problems check your cpu with taskmgr.
So you cannot play video with A2DP unless you have 1Ghz!!! good for battery life.
If you like music you want good earbuds. There's none with A2DP.
So what's the point again apart from having to charge one more device?

1: Well, I'm not sure on the bluetooth 2.0 specs, so If there is a spec limit on 64kbps, then this is new to me.
2: And the skippingproblem is not just connected to the CPU-usage.. But if you have some info on this issue, then please; do share it with us.
3: A2DP headset with minijack is available many places, even HTC has one. And if you take a look at DS970, you will see that it's the same as Sony MDR-series.
4: And well, the CPU usage is a issue, but that is the only part that I agree with you on..(but let us be frank, I've bought a pair of A2DP headset, so I do smell a bit "conflict of interests" here...)
And to the bottom line, I've bought the Trinity because it's one hell of a gadget, and so is bluetooth stereo So if anyone want to shoot me for that, well hell yeah, go ahead
Edit: And FYI meroupow: I do feel you are a bit rude in the way you wrote that response, or at least a bit arrogant when you post a comment like that. Trying to mock people who have bought A2DP headsets and are tweaking and fixing issues to make them work correct(this also goes for GPS on the phone, black coating comming off, improving camera quality, getting the ATI ImageOn to work correctly... etc) . And I must honestly say that yes, you do have some points there, but you should be able to present your views in a much more polite way...
Sound better but discontinuou. Impossible ear music. The sound goes on and off continuously. Why?. How can I do?
I am sorry if you felt I was being rude.
That was not my point and It was probably the wrong place to say what I said.
It is just that just like you I bought this A2DP stuff with my Wizard.
Just like you I tweaked it as much as I could and managed to get it work.
The problem is when it comes to sound quality is important and just working is not enough.
When you show your happiness because it's finally working, people think you are happy because it's good and they are buying it. And get disappointed too.
I just wanted to warn people on the fact that it's not working to watch movies because of cpu and that a 5$ earbud will have far superior sound quality.
It's just a toy and by no way a mature technology.
I've got a CB2530, hard to pair and I still don't know what do I do for the pairing to be successful, but I do manage to pair it after a few attempts, on the registry I just disable jointstereo, set the MaxSupportedBitPool to 320 and the quality is quite nice and with minimal skipping. High cpu usage of course, but if I set the MaxSupportedBitPool to 80 the quality is quite crappy and the device gets equally sluggish(gets worse when you touch on the screen, as K-Rally does even with the new ROM).
As for the pairing, I still haven't confirmed, but I think the registry setting that enables the bluesnarf option on BTCrawler has something to do with it(the bluetooth ISC mode thing), because right after setting it I managed to pair the headset right away, the thing is, I was also successful in other occasions when I hadn't set that reg. option.
Hearing the pairing sound from the trinity or headset doesn't indicate anything on my case, and I think I've already tried these reg settings you mention, but I'll try them again as soon as I get home to see if there's any difference and post the results.

Install the Widcomm BT stack. With that, you won't have complaints - neither have I.

Does anyone know what is changed when you DO pair with the button on the headphones? With some models, you MUST do it because, otherwise, the music will be muted after about a second (see http://forum.xda-developers.com/showthread.php?t=282008 for more info).
I've searched around in the Registry for changes, without any success. It's possible we could directly edit the headphone connection-dependent parameters set AFTER the headphone's initiating the connection to avoid sound problems. If we knew where they're stored, that is.

BTW: is it the profile and software on the phones/PDAs that arn't handling it, or is it the standard itself that sucks? (or in other words, should I keep my headset for later usage or return it to the store)
I use Plantronics 590a and the skipping problem appears very rarely, mainly when I use volume/track buttons on headset. However, yesterday I also connected the headset to a normal stereo (via the 3.5mm adapter) and noticed the same occasional skipping. So in my opinion the skipping issue problem might be from headset, not Trinity.
I also tried a Nokia stereo bluetooth headset and noticed serious skipping problems - unusable.
PS: there is indeed a skipping problem if I open/close other applications while listening to music. It looks like the processor is very busy - system very slow etc.
PPS: any suggestions for a player that has equalizer? WMP doesn't and the sound is not that great (especially when compared to my old SE P900 which had an excellent player - best I've heard so far... )

Stereo BT experience is very positive
Hi all,
As always, someone has to have a different view of the issue. I got my trinity a couple of weeks ago and went and bought a Plantronics Pulsar 280 stereo headset. Mostly because of the stereo jack. I have not updated trinity nor have I applied any fixes, just paired right out of the box, as always from trinity BT manager. It really sounds great, particularlly the base is fantastic because of the earbud design. Even you may choose the actual headset of your dreams by using the standard 2.5mm jack. I have owned a "no brand" headset (still do) but it is not BT 2.0 and I think it makes a difference. The plantronics does not skip and it sounds great. Most of my MP3 is 128k and above so no limits with that. I have not checked my registry settings as they are default rom image set. I am using ROM 1.15.412.2 and Radio 1.20.00.11 (my trinity only speaks spanish for now, hope to change that soon).
Point being that the software and quality of the headphones makes all the difference, don't be so quick to blame trinity, just a piece of my mind. Keep it up guys!!!

I have been looking into increasing the mic volume on my X1 when using a wired headset, as people have commented that my voice is too low when on a call. There were no complaints relating to the volume of my voice when I used my previous handset, K850i, and the Sony Ericsson standard wired headset, HPM-62, so I started researching the issue. I came across a lot of other users who have used Windows Mobile devices, specifically HTC devices, and who also experienced the same issue, however, they resolved it by using this registry tweak.
I checked the registry on my X1, but there are no audio gain options present and I was unable to create them successfully. I was wondering, has anybody managed to increase the mic volume on calls, in general or when using a headset, either via a registry tweak or by software?
I actually never had this problem. I check the registry and couldn't find any in-call related audio settings. Can't help you there I'm afraid.
Wonder if it will work if we just import these settings from another phone with these registry values present.
Can somebody post them?
I don't think it uses that system any more, instead it uses the .cpl files in windows to control audio levels.
Have you tried a different wired headset? it might just be a quality control issue with your one?
the only person who ever complains that they can't hear me on mine is my other half, but as I've pointed out, it's just another great excuse to moan at me, (she hears that bit fine)...
You could try one of the mini-USB wired headsets around (as long as it's not a silly HTC bizarreusbplugfittingthing),
something like this; http://gpsforless.co.uk/product_details.php?id=15774 (but not that one as the cable broke really quickly on the one I had).
I had one for my athena and it was pretty loud.
Not tried one on the X1 as I'm happy with the levels out of the standard headset.
[edit]
just had a thought, have you tried microphone automatic gain control? (it's in settings)
there are registry entries for that.
HKCU/software/htc/softagcdata (this on ITJES rom anyway, which uses quite a lot of Htc stuff).

use advanced config 3.3 goto bluetooth settings and put ALL values to max, reboot and thats it.

I have a chinese bluetooth rearview mirror without digital volume control (only an analog knob like a fm radio volume one), and the output volume was extremely low with my new hd2 (with a nokia n97 was perfect).
Tried to modify registry settings without any results.
Then I discovered that disabling "single volume" for ringtone/system in settings i was able to raise the conversation volume using the hardware volume button on the left of hd2. Now i'm totally satisfied with the output power.
you might set the volume with the volume keys on the phone when connected to headset.
Hello,
I have a wireless bluetooth stereo and when I connect it with HTC HD2 it always plays music to the loudest level. The volume control level of the phone (volume buttons on the left side) works fine (volume bar goes up and down) but the volume on the headset does not change.
I tried different music players (such as nitrogen which has volume control but still volume level didn't work).
However, when I am talking on the phone using the wireless bluetooth the volume control works fine. The volume controls works fine also when I have a wired headset connected.
This is my headset: http://www.sonyericsson.com/cws/products/accessories/overview/hbh-is800
Anyone else had the same issue?
P.S. My wireless bluetooth headset is working fine as I have tested with other phones such as Toshiba TG1 (my previous phone - HTC is so much better), Sony Ericsson P1i etc.
Thank you
Use the volume control of the headset, then it'll work fine. The bt audio isn't routed through the HD2 volume control.

There is no volume control at the headset.
I have the same issue here and my headset worked fine with my Xperia X1.
This headset is A2DP and should work with this phone
Maybe it is something with the Widcom BT-stack vs. MS
..JL
As jorglund said, there is no volume control on this handset
Too bad, I can't use it with this phone.
You would expect a phone like HD2 to support it.
for media player: no digital volume control on this headset like holding the play button until volume changes up-down?
for phone calls: did you try volume control on phone while in a call? does that work? (that should work)
for media player: I tried to hold down the play button until but volume did not changed down/up (it works with other phones).
for phone calls: Yes that works fine, the volume controls for phone calls is ok.
The manual says some phones don't support volumecontrol. On my Sony headset holding the play-button controls it's own volume for audio. However I cannot change callvolume with that headset.
Must be one or the other.
You are right.
I also read on my headset manual the following:
"The music volume cannot be changed"
"Some mobiles do not support remote volume control. Please check the support website for downloading the additional software"
Hello! don´t waste your time friend, I have my hd2 since Dec. 1st and the same headset,HBH-IS800 from my previous phone, and tell you that unfortunately are not compatible with HD2.
thank you mate for letting me know
this the headset that I use now:
http://www.amazon.com/Sony-MDREX38iP-BLK-Earbud-Control/dp/B002M78JA2
is a very good one,no BT
I've got the same problem with my Jabra JX20 headset.
I use it for phone conversations, but not so long ago i remembered it supports A2DP. So i tried to listen some music through it, but the minimum volume is just killing my ears.
You can however adjust it somewhat through direct volume controls on the BT headset itself, but it is still way too loud if you turn it down to minimum.
I don't know who to blame here, HTC or Jabra, but i must say i'm really dissapointed with both of them since they so proudly state their A2DP capable phone/headset, but in the end you have to find out on your own if this A2DP thing really works (f***g lottery).
Does anyone know any software solution for this problem?
Same problem with my Jabra BT3030
Hello Guys
I use to have a HTC Touch which was a great little unit. I updated to the HD2 and tried to use my Jabra BT3030 (the one that looks like a set of army dog tags) and I have the same problem as you all. The music volume cannot be changed via the HD2. And the volume controls on the BT 3030 only reduce the volume a little regardless of what the volume is set up on the HD2. The HT3030 workded great with my old HTC Touch so what is the problem HTC? What is the problem and what is your! solution.
Are there any other bluetooth units out there that alow you plug in your own earbuds or canal phones (I use Etymotic er6i's and Shure SE240's)
Cheers guys

Hi guys,
Thought I share my experience with you.
I have the HD2 and the same BT SE headset, and the exact same problem. I have contacted HTC Customer Service and their reply is that the design of HD2 does not support remote volume control. FYI, I had the HTC Touch HD before and the same SE headset works great when listening to music; so much so my headset actually broke from natural wear and tear, and I have to have it repair/replaced. Unfortunately now it does not work with HD2.
I do hope HTC recognize the problem and that they will provide a fix soon. However, judging from the respone of the CS, I doubt that they are going to bother fixing it when they use the "design issue" as a shield. It is a little disappointing as HD2 is one of the greatest product of HTC yet.
Cheers!

What does this have to do with anything? Looking at the website, this driver appears to be for bluetooth keyboards and mice connections? Does this driver allow A2DP volume control? Anyone?
Am quite annoyed with this issue I have to say, I've upgraded from the Storm which was quite frankly the worst phone I've ever owned, but it connected and controlled my HBH-IS800 earphones perfectly. Would have expected much better from HTC. Have trawled the internet looking for a 3rd party A2DP volume control app, but no luck. I've noticed that one has been developed for Android though, so looks like this was an issue for that OS too but someone has stepped up to offer a solution. Any developers out there who could give it a shot for Winmo....really, anyone....?
Just FWIW, you can use SRS WOW HD to reduce the volume of A2DP audio on the HD2. Or at least, you can on my HD2!
1) Install SRS WOW HD, which I can't link you to directly because i'm still a "new user" apparently, but try tinyurl dot com slash ybxf4tt
2) Start => Settings => Menu => All Settings => System => WOW HD Settings
3) On the "WOW HD Settings" page, leave "Enable SRS" as disabled (no, really)
4) On the TruBass/Gain page, you will find "TruBass Level", "TruBass Equalizer" and "Output Gain" are disabled (because "Enable SRS" is disabled). However, "Input Gain" is enabled, and lowering it from its initial value of -1db will reduce the output level of sound played through A2DP.
This setting will survive the shutting-down of SRS WOW HD; it does not survive a soft reset. State the obvious, if it's still too loud at -12db you can turn on the full "Enable SRS" settings and play with the other sliders to get an acceptable level.
Working well with my HD2, Nitrogen audio player and Sony HBH-DS200.
I have HBH-IS800 and use Nitrogen. I know the volume control doesn't affect the volume of the headset, but if you go into the equalizer then the leftmost slider is for pre-gain. This adjusts volume and is how I use the headset with the device.
HTC have told me that they're aware of the issue and are working to fix it. That was over a month ago.
Altec lansing backbeat 906
Same story here. I bought a bt headset and volume control don't function properly. Pitty
Sorry to shout, but I guess it's the only way to get heard.
Use Nitrogen as your music player and use the pre-gain channel in the equalizer to change volume.
Hi guys
i read xda so much, but i don't write as well
i have a big issue with my galaxy s 2
i use a bt car stereo, with a2dp and avrcp support
i used to stream all my music collection from my iphone4
now i got my sgs2 and i love it... but
the audio stream looks "limited"
it seems a bandwidth issue, or i don't know a quality issue
with iphone4 i streamed at full quality, now the sgs2 sounds a lot worst
other than that, i have to disable wifi because if on, the music is choppy and skips a lot
with wifi off, the stream goes well, but it sound bad...
sorry for my not so perfect english... i hope there is a way to improve sound quality because i "live" with a2dp on in my car...
That's strange. My a2dp stream actually sound better from sgs2 than it does from my ipod touch 2nd gen, iphone or my computer (bluez).
Receiver is a belkin stereo a2dp receiver.
Are you sure that it's not in handsfree mode? Long press the a2dp device in bluetooth settings and there should be an option to select it to be a media device, make sure it's checked.
thanks for the reply gvoima, no it's in media device mode
i think the problem is the bitpool
i've got the same problem of this guy: http://forum.xda-developers.com/showthread.php?t=708685
there is an mp3 sample of the problem in the first page

I got a belkin stereo receiver as well, but it sounds bad and choppy, just like the topic starter described. Though still compressed (this is a known issue for A2DP due to bandwidth limitations) songs sounds much better from my Nokia E52 work phone.

The "but my (insert phone) worked better" isn't really valid. For as many people who make that statement there are an equal number who are shocked that the SGS2 works where other phones haven't. This is kind of like the Wi-Fi issue. When two pieces of equipment don't interact well you can't just blame one of them.
In my car and on my Yamaha YSP-4000 the SGS2's Bluetooth works better than any phone I've used. That includes the HD2, G2, and G2X. The sound is much more defined and headset controls (random and repeat) show available for the first time. The SGS2 also feeds track info to the car which none of the others did.
Bluetooth connections and sound quality are always a big YMMV.
My Sony MW600 sound great, I use to have a Motorola Defy , and it use to have an "Enhanced Stereo" option in the blue-tooth menu, the Samsung S2 does not have this option.
@BarryH,
Oh I know, I not blaming the SGS2. I only think the SGS2 out sound to it's output module which is somehow less suitable for the kind of compression, maybe set by the Belkin module. Actually I'm currious if there would be ways to change the way the SGS2 sends sound signals via A2DP

LG's implementation of Bluetooth drove G2X owners crazy. Check out this thread from the G2X forum...
http://forum.xda-developers.com/showthread.php?t=1117769
Maybe it will help. The only other solution for the G2X was installing an AOSP ROM.
Well, I tried it (Bluetooth Fix Repair), but off-course that tool is for a problem the SGS2 does not have.
From the tinkering I've done now I know.
- Having MusicFX installed does not make a difference
- Video players running ffmpeg codec do also not make much difference in sound quality
- The -type- of file does make a difference, i.e. low bitrate files play better
This makes me think, is there a music program which can resample/recode music before playing. I'd rather have software do that than A2DP do it badly, or is mono output (other than all the tools enabling playback on mono headsets which is for pre-A2DP headsets and thus something else) possible?
Edit /system/etc/bluetooth/audio.conf
Uncomment "Master" option and set it to "True".
Uncomment "MaxConnections" and set it to 3.
Most Android devices have this file configured poorly by default, those 2 settings should help though.
I'd suggest also enabling HFP and AutoConnect.
Great! That definitly reduced creaking/noises and even the occasional stuttering music!
Since you seem to know your stuff, would there be a way to send a mono signal to (only) the A2DP stack and would this decrease the 'tin can' effect? I'd rather have better upper tones than stereo.

Thanks for the suggestions...going to try this and see if the sound quality improves in my car stereo.
Till now the best A2dp sound quality was on my Nexus S, but that was with the help of custom rom development and vodoo sound. Worst was the g2x.

Ok guys, I think I might have... accidentily... run into a phenonemon.
I tested my phone on a Creative D100 wireless speaker it it went great, no tin can sound, no hickups.
This proved to me that there had to be something wrong. Now when I was posting here earlier I was listening a lot to music and at a certain moment I thought... wait I'm not hearing a tin-can sound anymore. However, later on while testing I heard it again so I thought I imagined it.
Powering off the phone and powering on again I was able to create this again. No tin can sound... however a lot of hickups (as if a lot of data had to be sent and it didn't quite fit). I made a call to my work phone (sound on the handset) to test and then the tin can sound was there again, no hick ups anymore though. Strangely enough a haven't been able to replicate the 'no tin can sound but hickup situation' though by powering off and on again. Tried after playing on the Belkin on the D100 again and no problems at all, great sound and no hickups whatsoever.
It appears to be a bigger issue with android connected to the bitpool setting the bluetooth receiver desires...

Let's hope the upcoming Cynogen can fix this issue.
I too felt that the A2DP sound quality on the Nokia BH103 is crap as compared to my Nokia 5800 (sounded even better than stock wired headset). It also uses a lot more battery, I find mediaserver using a lot of battery.
How do we escalate this to Samsung?
