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.
Hi,
I had the Cingular 8125 and I upgraded to the TYTN (shelled out the dough for it) only because of it's 3G capabilities and MAINLY because I wanted--needed Stereo Bluetooth. I have a pair of expensive 590A Plantronics Bluetooth Headphones and wanted to use them with the TyTn. Let me say, I don't know why, but the sound quality is not good. Anything with bass sounds crackly and distorted. And I know it's not the fault of the headphones because I've tried these headphones out on other devices (HP 6515) and they sounded great!
One more thing: what's up with using Micro SD? I went from SD (4GBS) to MINI SD (2GBS) and then MICRO (2GBS) but, seriously the size difference isn't remarkable and the phone could have held an SD card which would have made it more convienient when dealing with laptops and having larger capacities.
IF there are ANY tweaks or upgrades to fix this crappy sound quality of the bluetooth. PLEASE LET ME KNOW: my email is: [email protected]
THanks.
the wiki is your friend here...... the precise answer to your question is there.
also, beware that there are only a few A2DP headsets known to work well with the TyTN and your plantronics isn't one of them. This doesn't mean that it won't work, only that we haven't tested it. My notes thread details the known tested good headsets btw. Because of this, while the WiKi will show you how to improve stereo quality, you may not be able to fix your skipping issue.
I just bought a HTC S100 BT Stereo Headset. It works OK, but only with joint stereo active. If I set the UseJointStereo to 0 (Registry Settings) the sound is just awful!
And yes, I tried alls the different settings for better audio quality - that does not make a change at all.
Is this problem known? Any remedy?
A
Problem known and due to the poor M$ stack...
Only solution for decent BT stereo is the Widcomm stack (see the wiki)
It is painful to use (need to reset to avoid out of memory message), but the sound is great and it works along the M$ BT stack (not at the same time so...)
there are a few bt headsets that work well. my nokia hs_12w works well, but it was pricey. bulky too. my older no-name one had a terrible hiss, but this nokia doesn't.

I need help with this also.
I installed the A2DPfix and the skipping is now gone but the quality is still very poor. There seems to be a lot of static noise or something. I applied the HTC Tweak A2DP fix for quality but it didin't do anything and now I can't get rid of it.
Please help.

Do follow my articles - I've elaborated on this problem in several of them. See for example http://www.pocketpcmag.com/blogs/index.php?blog=3&p=1744&more=1&c=1&tb=1&pb=1

Wow. that is some extensive article. I tried reading through it but not sure what i'm looking for. The article doesn't talk about the Logitech Freepulse headphone. Can you be more specific?
I was wondering if any of you who has access to this device tried to see if it also suffers from high pitched noise like other devices when used with A2DP devices?
Is this using the sandard WM bluetooth stack or have they used an improved one?
Thanks
the Bitpool could be set as high as possible, dont know why MS set the default at very low since many devices support high data streaming.
without tweaking program, average people would think bluetooth quality is poor on this device.
Lurking around for years, I would expect anyone to search and apply suggested fixes in this forum before coming to a conclusion and askind this question.
Actually, I have applied most of those settings in both polaris and diamond. Even yough it is reduced, you still notice the noise during silence. Especially id device volume is lower and receiver volume is higher. This wasn't the case in n95 and SE m600.
Similarly in Vista with built in bluetooth stack there is some noise. Using a different stack such as Widcomm produced totally different results with same receiver.
if it was good in the m600... sony ericsson...
but it's made by HTC so????
Hi all !
I'm looking around for ways to better my audio experiences in A2DP with my HTC Touch Diamond. I keep hearing these high pitched metallic noises, and based on your posts, it could be an issue with Bluetooth stack. Is it the same with Xperia ? I mean, does A2DP sucks ?
These noises are a nightmare... I am using Diamond Tweak for my Diamond, any setting ideas ? Didn't try anythng so far...
Thanks a lot !
is it just me??
there aren't that many reports of this issue on the net. it was briefly mentioned on one of the reviews and that was it.
anyway, on higher bitrate mp3 playback, bluetooth headset audio stutters and skips a lot, even if the device is held very very close.
wifi was not running, 3g data was not on.
if you guys think the issue I posted on google Android's bug site is relevant, then please vote.

Desire as well?? wow..
i think perhaps ill try disabling the HTC Sense or something
just dont understand why no one's been complaining
whats the x10 like by the way...it looks really nice but someone somewhere said SE's skin is slow?
how much battery life do you get out of it?
I do have trouble using just a plain headset. I only get about 30cm range before the audio begin to stutter.
I've tried with two different Sony Ericsson headsets (HBH-PV710, HBH-610a) and a TomTom Go930.
Is it a software issue or hardware related? Repair?

am guessing it's hardware...
but perhaps it can still be helped by modifications in software
basically im still getting the same issues with a custom ROM
Got the phone replaced with a brand new, still the same problem.
Audio in headset is really bad, but in the other end they can hear me loud and clear.
Could it be poor output power from the Bluetooth transmitter in the phone,
while reception is good?
I've restored it to factory settings, and had WiFi disabled.
I've got the same problems on my Legend.
Both A2D2-profile and standard audio for talking.
No more than 80-90 cm before the static and noice occurs.
My colleague here at the mobile-store had the same problems on Hero, and now on his currently X10..
So to me this seems as an Android problem overall, but I can't tell for sure..
My Legend is my first Android handset, and I like it..
I only wish these blutoothproblems hadn't been here.. Should have been just the same as on my beloved Sony Ericsson handsets..
Got a new headset a Nokia BH-602 and the audio is a lot better, not perfect but at least I can hear every word said.
It's quite strange that SE HBH-PV710 and HBH-610a including TomTom Go930 just didn't work.
I'm just curious what qualification Android or Bluez did meet to certify for the Bluetooth standard.
Sorry to bump an old thread...
But just wanted to add I have the exact same issue, the bluetooth range is not very far at all, however it is a lot better then 30-60cm.. i'm able to go for about 2-4 meters with line of sight.
So i guess its usable as long as the phone is in my pocket which is fine.. just wish it was a little better like my previous phones where I can just leave it charging and walk around the house.
Bluetooth support is pretty atrocious on this HTC Legend.
Never had any problems streaming audio or using any of my previous devices with my car stereo for handsfree.
But this Legend is pants! - It won't work with Bluetooth Audio streaming at all - I just get static and some wierd clicking noises (using 2.03 latest official ROM) and handsfree connects ok - but then drops half way through a call causing me to lose my call at the time.
Any resolves for these bluetooth woes?
thanks in advance.
PS - Using it with my Pioneer FH-P80BT
I use my Legend with a pair of Sennheiser MM400 headphones. I have no stutter with bluetooth stereo (except minor cuts when browsing some intensive websites or typing fast in landscape mode). My headset works well even with the phone in my pocket (although it skips momentarily if I turn my head right or if my hand touches the bluetooth transmitter near the camera lens).
Perhaps some of the reported problems are caused by some background process using CPU cycles with high priority?
Incidentally, I highly recommend these headphones - bluetooth playback is of identical quality to wired playback. I don't know how Sennhesier have acomplished this feat but every other brand of bluetooth headphones I have used before have had intolerable reproduction of high frequency sounds.
I am having this problem as well...streaming music from my T-Mobile Vibrant to my radio via bluetooth. The radio is bluetooth 2.1 compatible and the Vibrant is supposedly Bluetooth 3.0.
I used to have a Mytouch 3G running Android 1.6 and I do not remember having this problem.
Same problem here !
am using Legend, and "Jwin Stereo bluetooth" headphones that needs "A2DP" to work, and its working clear but there is some silly cuts while listening mp3's and its disturbing me, i cant ignore these cuts coz are alot !
Please tell us if there is any way to solve it ...
Thanks..
