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?
[email protected]
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 was wondering if anyone has a consisce, reliable way to eaisly enable streaming bluetooth audio on an 8125
mine is pretty much bone stock except for spb pocket pc.
Thanks for any help,
Pat
Are you looking for stereo bluetooth sound or just through a mono headset?
Stereo (A2DP) support should be built in, depending on when you purchased the phone, but if you just want to stream music over a bluetooth headset (mono, low quality), check here.
thanks

awesome find works perfectly but alil grainy
ad2p
if u enable the ad2p on the 8125 itll sound better there is a cab sunwhere i used and it werked great after a softreset.
I found that the default A2DP setting in Athena is used JointStereo,
After I use Registry Editor change JointStereo value to normal stereo the sound quality is become poor,
many high frequence tone in my I-tech Radio (I-tech R35 with radio function),
but this problem haven't appear on jointstereo.
I don't know why HTC use jointstereo than normal stereo there may be some reason was hidden.

Hello seems to be a recuring problem of all HTC phone
just see threads of hermes, P3600, etc
with my Artemis i have the same problem, i try to change joint stereo or bitpool and i get very very poor sound
so i resigned to let the HTC setting , it make poor sound but "earable"
so the question is : why ???
in artemis i forget it because of the 180mhz poor processor (remenber htc didn't activate A2DP in prophet because off it)
but i was expecting that X7500 work great with A2DP blutooth !!!!
what the hell are doing the htc's technical team ???
i can't beleve that !!!
i think that this time i'll pass the X7500 and go to ETEN or ASUS

What is sound quality of normal wired headphones?

it's more depend on what headphone you use, and because of this, i am pretty sure my DOPOD U1000 generate the greatest sound i won't go in details of this, because this is a PDA forum not a headphone one
Great A2DP Quality!
I agree with Wu, the audio quality of the A2DP is amazing, the best I have experienced using Bluetooth A2DP, plus the distance I can have between the headphones and the Dopod U1000 is even better!
I am using Motorola's HT820! Great sound!

Agree 100% .
I don't thing U1000 provide great sound quality! I try same headset (I-tech Radio + Shure 4G) on different A2DP device Asus535, O2 Zinc, G-Smart i+, Dopod900 and Dopod U1000. Only HTC device have high frequence tone distributed to A2DP headset. Other device provided a stable and great sound quality on A2DP.
it brilliant with my nokia hs-12w

if you have shure 4G, then don't use the bluetooth, plug your headphone straight into the socket, otherwise you will waste the headphone.
For everyone else, unless you really like the idea of having bluetooth headphone, otherwise to archive maximun sounf quality, you should plug your headphone straight into the Athena
Hello all.
I've been having this somewhat annoying issue. I've tried a few of these bluetooth audio routers that let you use any bluetooth headset to listen to your music. I recently lost my old a2dp enabled bluetooth so I purchased a jawbone 2. The issue is that the audio routes to the jb2, but it sounds really low quality and low volume. This so far has been exactly the same with the following software: BTaudio, acbToggleBluetooth, BlueMusic, and BluetoothAudioRouter. Sucks because I just upgraded to DCD's latest rom hoping it was just an issue but wasted my time because I had to reinstall all of my cabs and have the same results lol. If anyone knows anything that could help, it would be much appreciated.
XV6800
DCD's 3.3.4 ROM
RADIO 3.42.50
I am having the same problem. Any fixes?
Nothing, I've tried every program and many bt headsets, nada.
LOL- you guys are expecting A2DP quality from the handsfree/headset profile??
It doesnt work that way. Headset profile is heavily compressed to be roughly the same quality as a phone call (since it was designed for that purpose). When bluetooth throughput was enhanced in later revisions, they created the Advanced Audio Distribution Profile (A2DP), which allows for higher fidelity sound and stereo encoding for a decent wireless music experience.
The "routing" apps just take all output from the phone's audio system, and push it out to your standard earpeice using the headset profile. There's nothing wrong with your phone or headset, what you're hearing is a limitation of the bluetooth profile. It will at best sound like on-hold music, or someone playing music for you over a phone call.
Only way to get high quality is to use the high quality A2DP profile with a compatible headset.
How do we use the A2DP Profile?
To Dishe,
My HTC Raphael supports the A2DP profile so does my headset(it works flawelessly via bluetooth on my laptop) but i can't route music to the same headset via bluetooth.
Any ideas?
So some people have been complaining that bluetooth audio quality (when listening to music) is bad. Other people chime in and say theirs is great. So I'm wondering if one of the kernels or versions has better bluetooth auido than the others or if that's even possible. So I was hoping some of you guys could post if you think you have good or bad bluetooth audio quality and which android version and kernel that is on. If I find everyone with a certain version says their quality is good, maybe I'll try to switch to that one.
I'm on android 2.3.5 kernel KJ4, I would call my bluetooth quality bad.
No one has any input?
Everyone has his own opinion on audio quality.
The stock rom has a bad audio performance,but you can improve it by using cm dspmanager and libcyanogen-dsp.so
It will make the sound awesome.
Hi
I am also very interested in getting the best audio quality on my bluetooth headset... but i don't now anything about "cm dspmanager and libcyanogen-dsp.so"...
could you deliver me a more n00b friendly explanation how to solve this problem?
thanks in advance
