Poor BT Stereo (A2DP) quality?

I use a no brand Stereo BT headset on the Atom and found the quality is unacceptable poor. I just want to confirm if it's just me or it's a common problem for Atom.

I found the BT stereo quality very poor too. Tried
1. i-Tech S35
2. Gobalsat BT-830 (apart from stop/pause, AVRCP works fine with WM 10)
3. Nokia HS-12W (apart from stop/pause, AVRCP works fine with WM 10)
quality is way worser compared with the original headphone that came with Atom. I read somewhere this was due to the poor audio chipset used in Atom. Any way to fix that?
BTW, all the above 3 Bluetooth stereo headsets have excellent audio output when listening music from PC (using Widcomm 4.0.1.2800).

I believe it was due to the BT version used. I too tried
1. i-Tech R35 (V1.2)
2. Nokia HS-12W (V2.0)
When pairing both of them with Atom, the sound quality is not that good (always got hissing sound). The same applies when I use the i-Tech headset with my 818pro.
On the other hand, when I use the Nokia headset with 818pro (A2DP enabled), the quality becomes quite good (no significant difference from wired headsets). BTW, I think the Moto BT headset supports V2.0 too, and seems ppl around got some good experience with it and 818pro.
As I mainly use my Atom nowadays (my 818pro got the screen misalignment problem unfortunately), I already forgot about BT headsets.

From all you guys comments, I am not alone in having poor A2DP quality. It's a shame for giving out A2DP but unacceptable quality. :evil:

I-tech S35
Thanks so much for that information. I was really tempted to "upgrade" to an Atom from my Mini because the former had the built in bluetooth so it's a good thing to know I shouldn't upgrade because I was really after the A2DP functionality (since I thought the full release a2dp would be much better than the mini's "hacked" a2dp).

Maybe the stack used on the Atom is not that good. Have you tried upgrading the ROM?

what are u guys sayin ?
the quality of A2DP in my Atom (last ROM upgrade) is excellent !
and i do know how to appreciate the quality, cause i came from a V3x (quality was amazing too).
i am using the motorola HT-820.
the sound is much better than my crappy ipod video (to sell if someone interested) :arrow:
to fix ur problems, u should :
1- upgrade to the latest rom.
2- turn the crappy equalizer off (its a really useless feature)
3- when u go to bluetooth settings, hold ur bluetooth device and '' set as wireless stereo''
that may be the key for clearer sound.
also i didnt like the equalizer (am i alone ?) i found that the speakers are worse than ever.
what do u guys think? :arrow:

How's it compared with the using the original headset came with your Atom? For me, bluetooth A2DP is way worse.
I used the same i-Tech clip S35 on XDA 2i, and the A2DP qualitiy is as good as the wired headset came with XDA 2i.
Thanks.

Wired vs Wireless
ok, with the regular wired stereo headset the sound is Ok, but not that good if i compare to my ipod video.
i highly prefer the a2dp system as it seems ur inside a nightclub while using it.
but if i have to choose between the wired headsets or the HT820, i would rather go with the BT headset.
the only thing, is that dangerous for life ? (like getting brain cancer etc... wish not..)

As I mentioned before, I have tested all the combinations for 818pro, Atom (both with latest rom) and two BT headsets i-Tech R35 and Nokia HS-12W, and only found that the BT 2.0 combination, ie, 818pro with HS-12W, produces good enough music quality. For all other combinations, there is always some pretty obvious hizzing sound around when playing a soung. That hizzing sound is not background sound, as it won't appear if I stop playing any song. It only appears when a certain part of a song is played.
It seems to me that the hizzing sound is caused by insufficient bandwidth or over-compression of the data transmission (or both?). This also matches with my test result.
If I am using the 818pro (it is pending for repair), I will surely bring the HS-12W around. Otherwise, I will just stick with my wired adapter + Sony headset.

possible sol guys.
what is that ?
'' MSFP AKU 2.0 ''
it looks like a guy in another forum did an upgrade with this and got a superior sound etc...?
??? :arrow:

AKU 2.0 comes with support for A2DP.
In the case for XDA Atom, A2DP was supported on the day O2 released Atom.
A2DP quality in Atom was poor regardless of the Rom version, I tried the following roms:
1. 20060123B1WWE
2. Xda-Atom-ENG-20060123_Feb2006_.exe
3. R060221N_MN1ARC_RS00045
4. DSUU_ARC_C060414WWE_R060327N_EX0016__test_only_not_for_sale
5. Xda-Atom-ENG-20060426B1WWE
As described by buruburu, hizzing sound appears when a certain part of a song is played. Turning On/Off the equalizer doesn't seem to have any effect.
When listening the same song using wired headset, the quality was good, so can't be the problem of the song I am listening.
When listening the same Song using my PC (BT 1.2 with Widcomm 4.0.1.2800 stack), the quality was good as well.
So, no problem with the song I am listening, no problem with the BT Stereo headset I am using, no problem with the BT version (1.2 in Atom, 1.2 in PC; don't have BT 2.0, so can't tell) I am using, and my BT headset works fine making/receiving phone calls.
Conclusion:
1. the BT stack in Atom has a problem;
2. the audio chipset in Atom was a cheap and lousy one;
3. my Atom has a problem (I am in UK, don't have another Atom to test)
If it's (1), hope someone can fix it!!![/i]

tcmp
forgot to tell u guys : i get good quality cause i dont use crappy windows media player to play my mp3s, i use TCMP for every file i have.
and it works a charm.
the only thing i dont get, is that sometimes during the song play, it stops for a second then go back to it.
wierd :shock:

Aha! Finally found this topic. I'm on O² Atom + Jabra BT620s. The headset sound quality is superb stable on pc (5mb limit Bluesoil). On Atom... WM10 sounds too low even volume maxed, the equalizer doesn't work on A2DP. The best is on TCPMP where I can blast the pre-amp to make it louder. The quality is "ok²", hisses are seldom but hiccups exists once or twice in wma/mp3 tracks and too bad headset playback function only work on WM10 not TCPMP. And to click my headset when answering calls, I've to set TCPMP not to play on background, after clicking, I've to increase the headset volume.
Does any of you guys who's using other than Atom experience hiccups on A2DP? And those with Atom other than goldsaint? I don't think it's Jabra's but Atom fault itself. I've only SmallMenuPlus and O²Plus running in background (all startup removed), no battery/space monitors on today and overclocked to constant stable 520Mhz with XCPUScalar on the latest firmware. Thank you...

Am using I-Tech Clip S with my ATOM and sound quality is EXcellent!!! No hissing sound at all.

I highly recommend taking a look at the following,
http://forum.xda-developers.com/viewtopic.php?t=54621
I had the same complaint, but these registry edits cleared up my quality problems almost entirely.

Tweaked the bitpool settings to 53 but did not recognize any improvement. The other 2 tweaks is useless for me-- whenever i used my I-Tech Clip S BT headset/wireless stereo, can't hear the other callers voice. Streaming audio to my Clip-S is OK but no noticeable difference.
Cheers

I've tried my two bluetooth stereo headset on HP-2210 , DOPOD 818Pro and O2 Atom,one thing is certain,the sound qulilaty in O2 Atom is worst and poor.I consider the problem is ROM Firmware.

Some of the tweaks cause more harm than good
I removed all traces of these tweaks by doing a hard-reset, and my bt stereo is just fine with the occassional break. 8)
IMHO we should not just apply every tweak just because someone posted :twisted: EG some one claims he installed Atom Exec ROM on regular Atom Now he has vamoosed when asked to share. Some one posted a 4-letter word due to the mess he had when he followed that line :twisted:

Not to go against the current trend, but I entered the following into the reg editor and it made a huge improved in the sound quality using the Samsung SBH-100 headphones.
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Bluetooth\A2DP\Settings]
"BitPool"=dword:00000053
"SampleRate"=dword:00044100
Still get the occasional skip but fingers crossed something will come up to fix this soon.

Initial A2DP findings

Using the M3100 with the itech clip S35 Headset
firstly i've been using the fit4cat tweaker which has an A2DP quality improvememt tweak - unfortunately the tweak makes the quality worse so i've tuned it off and the music quality is not too bad when playing through my car stereo. However, I need to try some decent headphnes with the unit because the ones supplied sound very tinny!
Secondly, when you first pair the device, media player plays through the headset ok. If you then go out of range, when you return the headset re-pairs ok for the phone but the media player doesn't and it plays through the loudspeaker. You have to enter BT settings and recheck the stereo music option to have the sound through the headset again. Anybody getting this with the same or other headsets?
Thirdly, I have the S35 outputting through my car stereo. When people are calling me they can hear an echo (of themselves speaking as the sound comes out through the car speakers). There is some sort of delay i suppose but this is very annoying. I'm not sure why its happening because when I tried the headset using my Sony Ericsson W800i there was no such echo!
therfore, is the echo problem an A2DP thing (as the w800i does not support it and this works ok) or is it a m3100 thing? To test this I could turn off A2DP and ry the headset again - is this possible?
any suggestions appreciated

I have the Jabra BT620s headphones and I have indentical problems.
After install all works well but as soon as you disconnect media player just plays via the phone speaker

at least you guys get it to work once. WMP never plays through my iPAQ bluetooth headset. AVRCP controls work fine though. TCPMP plays fine through the bluetooth headset as long as I pair it up before I execute TCPMP. This is exactly how it worked with my 8125.
The WMP issue is very strange and is likely yet another example of the lack of QA testing in the A2DP portion of the TyTN's implementation. I would expect that these issues will all be fixed in a subsequent TyTN ROM update.

I'm getting on ok with this
quality is pretty good both using the headset with my own sony ear buds. Vast improvement over the itech supplied ear buds.
A2DP - no skipping during normal playback and it works well - quality is not an issue through the car stereo either - not bad at all . I've even been listening to music over A2DP and running sat nav using a GPS BT receiver. A slight pause in music when GPS connects but then all runs well.
My only 2 gripes are:-
1. When you disconnect or go out of range of the headset, it reconnect perfectly with the phone application. This isn't the case with the wireless stereo. I have to enter BT settings, uncheck the wireless stereo setting, save then recheck the setting before it reconnects. Slightly annoying but accesptable (for now)
2. the echo using the headset through my car stereo. People calling me can hear themselves again (about a 0.5 second delay) through the car speakers! Just to repeat my earlier post, this does not happen with my W800i. not sure if its an A2DP problem or something else.

Similarly here, I don't seem to be able to make A2DP (and the handsfree profile, for that matter) work.
Using HTC and an Itech clip, I am able to pair the "wireless stereo" and then play music for some 10 seconds on the GS Player, after which the Wireless Stereo symbol disappears from the top bar and the connection is interrupted. I actually believe that the Itech clip is 'shut off', as I have to turn it on again.
When I try to reconnect the headset, it just won't work and the whole machine is slowed down. Only a soft reset helps.
I hope this is a ROM problem (and not mine) and it'll be fixed soon...

WMP and the Itech clip work fine for me, with the current German ROM.

a2dp issues w/th Hermes
With the CHT9000 WWE rom I had the wireless stereo drop off after about 1 minute, then I would have to reconnect. I flashed to the other dopod WWE ROM (latest) and the problem is gone....sound is comparable to my prophet. Reg tweaks suggested in other forums definetely make the sound quality worse for either ROM version. I think further updated ROM's will improve A2DP reliability (or someone may find a reg hack)...as with the prophet A2DP it just takes time.

Hi guys, I've got the vario ii and the Sony Ericsson HBH-610.
I can add the headset fine and make calls through it, but I don't know how to get the music in wmp to play through it.
If anyone has a few mins spare and could explain it for me I would be really grateful

Headsets..HBH 610...
With my CHT 9000 I use an OMIZ 5660...works great for calls and wireless stereo. I don't have any other headset to compare it to (since I only have used this brand)....I believe that if your "options" do not list wireless stereo then you can't use the A2DP function on your device, at least as it is designed to be used.
I'm not aware of a one-piece headset that supports A2DP that is available (all should have either 2 headphones or two wired ear plugs)..

THE ONLY WAY, I FIND :
I have a 590A Plantronics Bluetooth HeadSet
You must refresh Services of your iTech or your Plantronics !
Go Parameters, Bluetooth, Select your Headset, Refresh.
Then reselect services and Save !
Each time you lost the link (Bluetooth turn off or ...) you will have to Refresh,reselect and Save !
I am searching for a Solve but not find another !

I forget something else !
It is the same thing with my Bluetooth GPS (GNS).

I have a spv m3100 and jabra bt620. They both work like a dream most of the time apart from having to go into bluetooth settings each time I want to connect to the stereo headset option.
I have noticed that when in my garden or at home (a quiet environment probably) that I have excellent streaming but when I am walking around, particularly in built up areas like shopping centres, high streets, tube trains, that there is some loss in the streaming which would seem to point towards some kind of interference.
Why the wireless stereo is set as mono as standard I can't understand. I'm sure its to do with improving the streaming quality, but they are supposed to be STEREO!!! Also I set the quality to 58 instead of 48 and there was a definite loss in streaming quality so I switched back to 48.
The AVRCP also works brilliantly in WMP.
The wireless connection also plays havoc with the bluetooth stereo connection with the buffering of stereo constantly dropping. Also noticed that AVRCP wont work with TCPMP, but as there seems to be some major issues with TCPMP and the Tytn I have uninstalled it for the time being until the guys at CorePacket come up with a fix

So far A2DP has worked fine for me with my Nokia HS-12W. I have applied some registry settings and optimised my SD card and so far it has played with hardly a skip. Definitely better than my previous BA with WM5.

This is the biggest problem for me with my M3100 at the moment. I'm guessing it will only be fixed by an updated\alternative ROM(?!), any ROM's out there I could try that might get round this problem??
Thanks

This is probably headset dependent because with my Nokia HS-12W if i need to reconnect i just press the Audio button and it re-establishes the A2DP connection. No going to BT settings at all.

Interesting, can you just confirm what you mean by the Audio button. Is that just hitting 'Play' in WMP?
Thanks

No, the Nokia has a Music key (not Audio, my mistake) which switches from A2DP to the built-in radio. So if i have lost the BT connection pushing the Music key to select the Audio player will re-establish the connection and music is streamed to the headset. You will see the A2DP icon on the today screen when it has connected and get the chime in the headset.

Ok, thanks for that.
Just one last point, if the connection is lost while music is streaming, does the audio switch to the phone speaker instead??
My problem is I'll be listening to music on the subway then or some reason I'll loose the connection (interferance, low battery...whatever) and immediately music starts coming out the speaker, much to my embarrassment!
Thanks again!

What's the best stereo Bluetooth Headset (A2DP) for HD?

Can anyone recommend something that already works well with HTC Touch/Pro?
Does Motorola S9 work with WM6 BT stack for stereo?

There are no good a2dp stereo headsets because the equalizer only works with wired headsets.. Htc: please fix this.

im using the sony stereo bluetooth headset hbh-ds980. works fine.. the volume for the music and for the phone calls are the same key but the headset keeps them programmed differently. so its nice. the onyl thing i saw that sucks is that it doesn't bring a clip to attach the receiver to your clothes.. so if you doing a lot of moving then its going to fly up and what not.. so thats annoying.. i took the clip from the standard HTC headphones that came with the phone and put it on the bluetooth and just slightly attach it to my shirt.

I'm using a Motorola S9 and it works perfectly. No problems at all, all buttons do work. Sound quality is very good!

One more vote for hbh-ds980. Been using it with polaris, diamond and HD. The music quality is quite good and functionality including addressbook and last calls access works fine.

The Motorola s9 HD's are out and the seem to have improved quite a bit. I personally have the regular s9's and they work great.

oh yea.. sry forgot to add.. haha. you can go into the recent calls list and into the phone book quite easily.. and have multiple devices hooked up at one time and get calls from them all..
the only problem is that i get the phone number instead of the persons name when they are claling me.. does anyone know why? the names show up when in the phonebook and everything..

Ok so not bluetooth but i use my sennheiser PXC 450, noise reduction...cant imagine better sound on the move

Sony DR-BT21G

I found an equalizer that works. The internal one in coreplayer.. Now nokia bh-903 bluetooth headset have bass and nice sound.

final conclusion the sound quality from the touch hd really really sucks

Ok well I went thru many testing options when it came to the sound quality out of the touch hd compared to other devices.
1- to test the sound quality I used the following players
a- core player 1.3
b- pocket music 5.1
c- touch flo player that came with the htc
d- pocket player
and all sucked big time, when I connected the device to a sony adapter cassette in the car. The sound is really awful comapred to all the devices I own like the iphone, or ipaq. WHAT THE HELL IS THE PROBLEM. I tried to use the equalizers in all the palyers, aslo the audio booster but the sound sucks. I tried to use also an adapter that has 3 rings on it to connect to the htc hd.
Please am I missing something here???

It all comes down to how you have your HD setup. First, check the app called "Audio Booster", it comes out of the box configured to sound like ****, turn it off. Get the HD Tweak app and disable the 100db sound cut barrier and use the graphics equalizer that is in your chosen player. I use Mortplayer and now I can say that the playback with my Sony in ear headphones is really good.
HD Tweak has a setting that should reduce the ring delay.

me I also agree that audio booster sucks, when switched off sound gets much better

Also, a cassette adaptor is likely to limit the quality you can achieve. Better to compare through a decent set of headphones.

Seriously man, putting that line in your topic title is misleading.
I've tested Touch HD's sound on high quality headphones (Ultimate ears Super.fi 5XB) and the sound is great even on stock settings. In fact, my iPod is getting a lot less playtime since I bought THD.

Did you notice any hiss in qiet moments or on gaps between tracks? For me that is exactly the same as it was on Kaiser

Yes I noticed a hiss and a small gap in a song, i even installed the hd tweak, and sd tune up. But still the problem remains.
I am not talking about using it with headphone, I am talking about using it on my car stereo, thru a sony cassette adapter. Aren't we all in need for a great sound in the car, and why all the other devices sound great on my car stereo except the hd

I only have Shure E2C for "in move" devices, but I remember them sound much better than with Touch HD

I'm having similar troubles here! Turning down the volume to about 30% on phone and using car stereo volume helps a bit. Also try different players and get rid of the car charger! It truly sucks as my other ppcs & mp3 players do not need tweaking AT ALL! They all play & charge at the same time.

Is this a joke? Sorry I am confused. You are talking about the needed GREAT SOUND an than you are talking about some funny CASSETTE ADAPTER?
Conclusion: If you want great sound in your car, you should not spend all your money for a phone - How about new car stereo - some of these funny new toys supporting funny things like LINE IN or USB-MP3 or Bluetooth A2DP / AVRCP (handsfree profile). I had a really hard time to remember how a cassette looks like.
The next one blames HTC becauese the HD doesn´t sound good when connected to the phono-in of his late ´80s stereo.
From my point of view, the HD serves a better quality as most of my "old" mp3 Players, better than my iPod but not as good as my MP3 from Philips. Even so, yes i´ve noticed these short lagggggs in playback. I wouldn´t have noticed them if someone here hadn´t mentioned them.... so thank you
What´s next? 8-track tape adapter doesnt work right on your high end car stereo?

My Kaiser didn't had any... But in the HD I notice it happens once in awhile using bluetooth phones. But in general i got tell the SOUND ROCKS.... (after you used HDtweak to disable the 100dB limit!)

The title is really misleading for a new costumer, it's not true that the sound output sucks in my tests it resulted better than my old n95 8gb and an ipod touch.
For the average costumer the sound output on headphones is good.

If you are noticing differences between devices when using the tape adaptor in the car but not when using headphones, there has to be something different in the setup. (Or you're using apple-grade headphones )
The tape adaptor is designed to mimic the response of headphones, so that the player doesn't see a difference. I second the suggestions of turning off the audio booster and 100 dB cutoff, as these can and often will interfere with the signal.
Once you've turned off the equalisers, try setting the volume on the player to about 50 - 70% and then adjust the car stereo to your required volume. There may be a mismatch when the HD amp is either running at really low or high outputs, causing distortion.
It would also be helpful if you could characterise the type of problem you're having: Hiss, low level overall distortion, distortion mainly on peaks, poor frequency response, etc. Different effects will typically have different sources.
NB: don't rubbish the tape adaptor! It serves its automotive function for me as well, although I'll take my Grados and Westones when the wife isn't in the car
Edit: Just did a quick comparison with my iPod Nano and there is very little between them on good headphones.

I can't confirm that at all, using Koss Porta Pro headphones and Coreplayer for playback (audio booster off, 100 db limit disabled, equalizer enabled) I get fantastic sound for a portable device, something's wrong with your setup.

Just connected my HD to my Z-5500 500W sound system using the analogue connections. It sounds perfectly fine to me, as good as anything else analogue i have connected.

I'm using my Touch HD with a pair of Sennheiser HD550 and some BOSE Quietcomfort 2 headphones. By no means super high-end, but good enough that I can say that the sound on my Touch HD is very good. No hiss at all, good clarity and overall good sound.
I have installed hd tweak and I tested the sound with Coreplayer and the inbuilt one in TouchFlo.

I can't confirm that at all, using Koss Porta Pro headphones and Coreplayer for playback (audio booster off, 100 db limit disabled, equalizer enabled) I get fantastic sound for a portable device, something's wrong with your setup.

Well Shure E2C are isolating earphones you put into ear channel. They are very sensitive, you hear everything louder than on any other type od headphones especially noises. And there is hiss/noise trust me. I also have headband Sennheiser HD580 & PX100 they are ok with HD. The trouble is that there is no hiss/noise at all if I plug shure's into my computer (SB X-Fi Extreme Music) and quality is also bit better.

I also have isolating earbud type headphones and the HD sounds no worse than any other Mp3 player ive used, including an iPhone or N95 8GB. Its not a high end audio device, comparing it to a 24bit reasonably high end PC sound card is not fair.

OK pass, I'm an audio-freak type. Maybe I just expect to much from HD

using UE triple.fi 10 vi's and the sound from my MP3's on the HD is very good... i have no complaints.

AD2P Audio

Any of you using the Desire HD with a BT Stereo Radio and/or stereo headset. The sound quality sounds really bad to me. I had the same thing on my HD2 @ default settings, but fixed that by changing the linespeed in registry. (bitpool on older WM phones)
Have been googling and can't find anything of the sort for Android. Is there a way to fix the audio quality?
My brother has the SE Xperia X10 and it has way better AD2P audio quality, even though it's still android 1.6. So it's not an Android bug, but rather a driver/setting somewhere.
Also the range the BT has is really small, I have a Logitech Pure-Fi Mobile speaker, which connects through BT AD2P, the quality is lower then on my HD2 (after tweaking) and the range is only 5-7m, while the HD2 managed to have skipless playback and higher quality at over 15-20m...
Apart from this I'm really loving the phone . And my car radio has full support for the other BT features. Like skipping tracks (in Spotify) and dialing numbers via the address book on my car radio instead of on my phone. And see who's calling on my radio's display.

Hi there, I'm really interested in that too. Would you say it's just a slight problem of the sound quality or is it merely unusable?

If you use Bluetooth headset you can forgive about good music quality. that's all
if you need good quality audio in bluetooth, buy this:

Won't really help at all, as I need to connect it to my car audio.

You can compare the quality with 96Kbps MP3 which is really bad imho, but still usable. It's about the same on many phones though, allmost all are set to max 31 bitpool... But with windows mobile it was an easy fix.

As the source code is out, I hope the ROM builders can soon find a way to fix this.

Hi
I use a pair of plantronics 590e headphones over A2DP and the quality is brilliant! I have not changed a thing in the setup.
I wont play anything lower than 192kbs (most of my mp3 are 320kps) as i am a real fussy git when i comes to audio.
I have used the standard music player and tunewiki and both are perfect!
Are you atchaly using the A2DP or standard mic and mono sound protcal for calls?

My MM200 Sennheiser work flawless. Music is rich and crisp!

You won't know the difference if you haven't heard the difference between bitpool 31 and bitpool 58, it's like night and day to me. Even 256kbps MP3 sounds bad to me tho.
Tried different audio files and it's not spotify causing it. As my brother is also plaything through spotify at HQ settings (which is 160Kbps OGG, comparable with 320+ Kbps MP3) ...
Eagerly waiting for an AD2P fix for android.

When I have my HD playing music through my Car's Bluetooth the quality is also pretty poor.
For some reason I can't choose any of the EQ settings? If I could just try and add some treble I think I could put up with it!

Just tried playing music via bluetooth to my sony head unit in the car and it became so choppy it was painful to even try to listen to it.
Great phone but really disappointed that there is a problem like this as one of the main uses of my phone is for audio in the car.

I use a Sony Ericsson mw600 and the quality is not good. The same headset with my sisters itouch and it sounds great. Is this a hardware or a software issue?

You must be careful with the mw600 that it connects in the correct mode. As headphones NOT headset for music. If you get it wrong it will sound awful. You can check by tapping the Mic during playback, if you can hear it through the headphones you have it set up wrong

i had exact earphone, but it's just awful. first of all; htc doesn't make me choose any sound enhancements, other thing is, my 320kbps musics aren't different from 96 at all.
ps. i am an audiophile.

Imanaged to find my old iTech BlueBand headset yesterday and gave that a go. Sound quality was loud and clear and well balanced.
Shame about the delay though - it's worse than I'm used to. Video is pointless as the lag on the audio is far too much to be bearable.
