Bluetooth Bitpool on Android - Desire General

Hi,
I recently got myself a HTC Desire and a pair of Sennheiser MM 100 headphones (bluetooth headphones).
I am noticing a slight hiss in the highs when I'm using the Sennheisers (you can notice that especially well when a drummer works a lot with his cymbals in a song) and the audio-fanatic in me finds this *very* annoying.
Out of curiosity I tested the headphones with my previous phone as well (Samsung Omnia: Windows Mobile). I noticed the same thing (although not as extreme as on the Desire). With a change to the bitpool setting (in the registry) I could however fix it completely on the Omnia (the Desire sounds like it uses a bitpool setting around 30)!
My questions are now:
Do you notice the same thing (is that normal on the Desire)?
If not: Is my device faulty (half-broken bluetooth connector)?
If so: Is there any way to increase the bitpool size on Android as one could with Windows Mobile?
Thank you,
Max

*bump*
It would help me as well if someone could tell if their device actually works fine with bluetooth headphones.

That depends what you mean by fine! My bluetooth headset works perfectly with my Desire, but then again I'm hardly an audiophile so perhaps I'm just not noticing what you do.
Regards,
Dave

Thank you.
Well, I would describe these distortions as very noticable as soon as there are a lot highs to hear.
I'm getting to a point where I actually believe that my bluetooth transmitter is faulty (is that even possible? A faulty transmitter that works well excluding distorted highs?).

Update: I checked another HTC Desire with these Headphones, it sounds exactly the same (which is bad).
The fact that the HTC Desire cannot stream music as well as the Samsung Omnia does is sad and renders those headphones useless (for me at least).
Thank you anyway,
Max

Your hearing is perfectly fine The problem exists with almost all Android phones, it is confirmed with HTC Desire, Desire S, Sensation and Samsung Galaxy S2. I have a Sennheiser PX210 Bt but I tried with Nokia BT headphones and other Sennheisers too. The root of the problem is probably the bitpool setting of the BT.
The only known fix now is using an AOSP ROM (like Cyanogenmod). Every Sense-based ROM is faulty because the BT stack is different than the Cyanogenmod one.

I noticed this also,
If I turn down the media volume on the desire, and turn up my headphones instead, it seems to sound better,

My Review of the Nokia HS-12W A2DP BT Headset

It's pretty good,
My first concern was that the sound quality was going to be rubbish, like when you listen to music with a mono BT headset, something I never did because aswell as being mono it also cut all of the clarity from the music ! fortunatly I can report the music makes it through in hi quality sound
My second concern was that the audio player was not going to work properly fortunatly although not perfect it's working quite well !! most notably the track listing is not showing in the screen, the biggest down side is that it stutters a bit from time to time, not so much that you want to throw it aginst a wall, but enough to be mildly irritating (seems to be linked to a bit rate issue) . also rewind and FF do not work with the universal, but next/previous track does, as does pause and auto pause on phone ring. I am a bit dissapointed that nokia did not include any kind of equalizer settings I personally would like some more bass.
The phone side is quite impressive I like the ability to quickly redial the last number or voice dial however due to the same limitations as the audio player it is currently not displaying peoples names only their number !! otherwise works quite well.
The FM RDS radio is a nice addition, it works well considering the aerial is the strap around your neck
my biggest overall gripe (ie wont be fixed by a firmware upgrade) is the shape of the earpieces, for a company that have been making headsets for this long these are awfull, it's like wedging big uncomfortable lugs in your ears, the real jasjar earpieces are way more comfy (and have better bass response)
So far only tested with media player as reports would indicate that for now A2DP only works with media player

Once the Pocket Music and Pocket Player people get on top of it, you can have remote control with their programs, as both offer equaliser/preamp.
Both are working on it.
Cool I look forward to it !!!
I have got to the bottom of my stuttering !! it is nothing more than signal strength, but I dont see why it is happening !! its hard to explain but the signal is not as robust as when you are just using it for phone calls. it claims 10 Meters and its true that in an open area with devices able to see each other both phone call and music will just about manage 10M however if you put an obstacle in the way (like a door) , where as the phone would continue to work the music player will not !! infact for 100% reliable music you are looking at 1 meter (open air) , and half that again if your phone is buried deep in your pocket.
check my review here:
http://www.mobileplanet.com/forumthread.asp?code=121010&thread=2
Guys whats your range like, i get no more than a meter away from my phone and the sound drops out, also have a hiss in the background that is really annoying at low volumes any thoughts ???
I did mention the whole 1 meter thing in my second post !!! I can't hear any hiss ( none loud enough to degrade the music anyway !!) tested with my Exec at full volume and media player also at full volume but the headset at minimum volume, ( thus giving the headset the best signal to noise ratio to play with )

Please tell me one thing: I've seen the unwired.net review state that the headset can connect simultaneously to a headset profile and A2DP profile, but only if coming from the same device, meaning that you cannot have A2DP coming from your PDA and Headset coming from your phone. Is this true? The guy said it was a preproduction model and firmware can be changed, so could you please tell me if this is in your model too?
Yes, this is true. It can only connect with one device at the same time.

That means this device is crippled, as it is very common for one to have music on one device and use another as a phone...
Do you know of any other product that offers the same opportunities in a similar form factor desides this one? I've found this one from Sony Ericsson http://www.sonyericsson.com/spg.jsp...der&php=php1_10394&zone=pp&lm=pp4_1&pid=10394 but it does not have radio.
I'm looking for something very close with this Nokia headset. Only one thing left, that I think very important. I want to be able to unplug the earphones from the unit. This is important, so that when we get to the airplane, we can unplug it and still use the same earphones connected directly to the Uni without the BT on.
Secondly, it will enable the unit to be plugged into Car Audio AUX input.
I have saw a couple of headsets that have this feature, from GlobalSat, and from itech. But both do not have caller ID screen.
http://www.usglobalsat.com/item.asp?itemid=98
In short, I want something like this Nokia, but detachable earphones like the Globalsat or itech.
I'll probably be getting this as well very soon. Just one thing, has anyone tried it with wizard and if so, what was it like?
Anyone know where to get one in the US? All links found so far are sellers in the UK.
im sure expansys US are selling it !!
Since my review I have tried it with a nokia phone and it performs better, the issue with signal strength from 50CM or less through you body has been improved. The main problem might be the positioning of the BT chip in the UNI, this may never be fully resolved !!! unless someone can hack the UNI firmware to tell the BT chip to broadcast with more power than it should.

Thanks, i will look at their site.
I bought the Nokia a few weeks ago but havent really tested until today. After reflashing the rom on my BA and installing the A2DP cab it works very well. Range is good with line of sight and the controls work ok. Only thing is an occasonal sound dropout of under a second, which has already been mentioned. Not enough to be a problem so far. Sound could use a bit more bass but that can be solved with a player that has an eq. Overall im happy with the Nokia.
I've had this headset for a week and am very pleased with it. Before this one I had the bluetake i-phono mini 450rx and they weren't half as good. This headset connects quikly, plays music with good sound, the radio is good with the programming of the radio stations literally being a minutes work. And most importantly, I can have a decent conversation with someone without problems. I experience stuttering ebery once in a while. But as commented above the range isn't great, but it's good enough to live with. The only downside at the moment is that I have to use windows media player that needs the playlist to be set up every time and the remote control doesn't work after a while of listening to music or after using other apps. I hope that this is a software issue. Before I had my mda I always had nokia phones because they were the best developed in their music functions. This headset strikes me as being the same good technology combined with A2DP. So in the whole I am very happy with this headset. I don't mind the earphones, I think they're comfy (far better than the original mda pro headset which gave bad sound and wasn't stable or comfy), everybody their own preferences. If I had to go for an alternative to this headset, I would go for the sony ericsson HBH DS970, but I didn't have the patience to wait for it and it doesn't have a radio built in. The only downside to choosing the universal was that it doesn't have a radio (something I've had in my nokia's for a while). Now my universal it complete and I am one proud universal owner!
ng
you can use the pocketmusic.You have to buy it but it works fine with the HS-12W. All the AVRCP commands works.
The HS-12W its really great. The only downside its that the universal dont use all of his functions. No ID caller, no play list in display, no message alert.
I belive that there is a software problem. I hope someone finds the solution.
But dont getr me wrong: the HS-12W is great.
I wouldnt say the HS-12W was great at all
my review:-
*sounds quality is good, but you can't unplug and plug in your own headphones.
*completely unergonomic design, Nokia should take a lesson from Sony on ergonomic remote designs, each button should 'feel' different. Each time I want to do something on the nOkia I have to actually look at it.
* it's pretty ugly, anyway no where near as nice as the HBH-DS970 (or whatver it's called ) the sony ericson one.
but as far as the basic connection, streaming that all works very well.
all just my humble opinion so take with pinch of salt
Here is a link to a user review of the sony ericsson headset http://www.howardforums.com/showthread.php?p=7463154#post7463154
I personally prefer the Nokia as it has a radio and the construction is solid. Also no problems resuming music after a call.
Everybody his own opinion, it all depends on what you want from a headset.
In any case I'm happy with this headset but agree that the headset has more possibilities than the universal uses, maybe in time there will be an update or something. But untill that time it works fine.
About pocket music, I'm not sure it works so great. I downloaded the trial version and tested it with some music, but the remote control didn't respond. Maybe I should try it again. I want to be sure the software is worth it for me before I buy it.

Jabra BT headphone
As promised;
I got the Jabra headset yesterday, and last night I was able to try it. First of all, sound quality is better than expected. Setup was somewhat confusing, since the manual is not so clear. But, I managed. Made a couple of phonecalls, all fine. Overall, nice set of headphones. Luckily, the flashing blue leds can be turned off.
Hi
I use the Anycom BSH-100. The Headset is not bad at all, with HS/HF/A2DP/ AVRRCP and a up to 200 h standby + upto 12 h music playtime.
Tech data here: http://www.anycom.com/products/bluetooth_audio_video/stereo_headset_bsh_100/?id=102&partno=CC3300
There is no buildin Microphone. A small (about 3 cm) mic is attacht to the side mini usb-jack. This mini usb-jack is also used to charge the batteries. Most of the time i forgett the mic, when charging the Headset, so i use the Headset often to listen to mp3s and recive calls without using the headset. ( a bild in Mic would be better) The headset goes to mute when a call comes in.
picture here: http://files.anycom.com/images/products/lifestyle/cc3300_lifestyle_01.jpg
+ (plus):
Handling is very easy.
Long Standby & playtime
small transport size (faltable)
- (minus):
seperate Mic
Sound Quality is OK but not as good as a normal wired-headset. (maybe normal for BT)
no option to turn of the flashing blue led
best regards Oliver
Hi, Anyone using Jabra Bt320 with the Touch? I tired to connect for stereo headset but its fails. I had the same problem with Dopod 810 but some after making some changes in the registry the problem was solved. I tired the same tweaks in Touch but it fails. Any suggestion from the forum? Thanks
I used the BT320
and the stereo was fine. I also made the adjustments to the registry and it carried on working fine.
However, I sent the unit back because I bought a Jabra 120s with it and found that, after initial pairing problems (which went away), there was an audio lag which made watching TV rubbish!
When you pair with the BT320s, you should have the option to use it as either
1. a hands-free or
2. wireless stereo.
If you don't, delete the device from your Touch then...
...plug the BT320s into it's charger, three times, for 4 seconds each time.
Now pair again and the option for wireless stereo will magically appear.
Try Motorola S9. Nice and solid. Matches Touch design too.

You get what you pay for comes to mind with BT headsets.
I have yet to come across one headset that plays great stereo sound
and gives you great call quality. However, for stereo sound the Motorola
S9 kicks arse over anything out there and the Jawbone does the voice
calls better than anyone out there. S9 is around $100US and the Jawbone
is $130US ish. Not cheap but you won't be looking to replace them because
they don't do their job. Now if you have a big melon the S9 maybe a problem.
AE!
Hi.
I got the HT820 from Mototola.
Sound is good.
Easy installation on Touch.
Noise cancelling.
Looks a little bit spacy but fits good.
AND I payed 12€ for it on ebay.de.
I use BT320s
Hi,
I am using Jabra BT320s, It just works fine with my Touch. I did the in pairing initially, but after I upgraded with latest firmware I don't have any problem in pairing.
firmware can be found here
http://rapidshare.com/files/51865424/JabraBT320swebupdate_1077.zip
Please read the instruction to update the firmware
Well i got the Motorola BT820 last week, very satisfied
great sound nice volume, little weakness but accepteble by my standard
when theres a lot of static noise the build in mic does piick up on that a bit.
i use it for mp3 mostly, and o yeah its comfortoble too
price is nice if i compare to other headsets,
still thinking about trying the new logitech headset
is there anybody who has experienced it
I have posted a question regarding a small problem with the Bb20s right here:
http://forum.xda-developers.com/showthread.php?t=326489
This is a description of my problem, as posted. Does anyone have an idea?
---
Received my Jabra 620s yesterday. First impressions: it is quite big and heavy, but it is better than earplugs ;-) Sounds quality is quite good.
Here is my problem: After pairing the headset with my device, everything behaves as expected until some event (this happend on multiple occasions, different trigger but the same result): the headset controls still function (i.e. I can skip songs etc), but the HTCs audio is routed to the HTC speaker instead of the headset. I cannot fix this, the only way is to remove the bluetooth connection, repair and I am good to go again.
I'd second the comment on the Motorola S9. I got the S9 to go with my old magician, but now that I've upgraded to the Touch, things are even better.
The S9 workd flawlessly for stereo music and also as a regular hands free headset. I can't tell you how many times I've been out jogging, litening to music and I get a cal from people. They say the call sound quality is good, but always wonder why I'm breaking fast.
I hve changed to HTC BH S100 (in-ear is better for jogging)
sound quality is good, no problems...yeah should be no problems when using HTC stuff only ;-)
i found the Motorola S9s to be outstanding. I have never been so happy with a BT headet.

Got it for 34 euro's and they make me happy.

Poor Bluetooth audio quality

Hi there I bought a Sony MEX-BT2800 radio this weekend and it has a built-in Bluetooth receiver for phone and music. My EVO pairs fine with the radio but the sound quality is really poor I have background static and a hissing noise whenever the bluetooth is being used. I thought perhaps it was the radio so I tried my phone on there floor model and I had the same noise problems. It could very well be the radio but some reviews I've read online from other buyers say there Bluetooth audio is crystal clear using there Iphones. I had my old HTC Excalibur lying around so I threw some mp3's on it and tried that phone on my radio and the static was still there but much quieter and the hissing noise was gone. So now I'm thinking it could be the phones Bluetooth radio that's causing the excessive static.
So I guess my main question is. Is there anyway to possibly adjust the bluetooth driver or audio stack to work better with my radio. I remember back in my G1 days Cyanogen would release new roms with bluetooth stack fixes.
This might be self-explanatory, but double check that the volume on your phone is all the way up when streaming. I get some hissy noise when the media volume is low, but I know that the sound quality of the bluetooth on the EVO is very good when paired with my car audio (at top volume), might be that you have a defective device.
Yeah I tried some different volume settings. Tried low med and high volumes on the phone didn't really matter what volume was on the phone. It must be the built in bluetooth module in this radio. I'm assuming your setup uses an external bluetooth module?
I have a Dual brand deck installed and I also bought a separate bluetooth adapter (with a mic and a 'call' button) that attaches to the rear of the deck via a cable, made by the same company. Maybe see if you can try connecting your EVO to a different type of audio device, if the problem persists your phone is likely at fault.
I'm having the same issues with my EVO on a different device - specifically the blackberry bluetooth media gateway. I have a little more technical details posted over here:
http://forum.xda-developers.com/showthread.php?p=7170018#post7170018
I've noticed a lag while using Plantronics Discovery headset. The headset was working fine previously with an HTC Fuze. So, I was under the impression that this was probably due to a faulty blue tooth stack on the device. Has anyone else had similar experience with Plantronics or other blue tooth headsets?

CM7 bluetooth question

I've heard that CM7 fixes android's pathetic A2DP bluetooth music quality... can anyone confirm this with their Evo?
I've got a pair of Sennheiser MM100 bluetooth headphones and they sound great on my old Windos Mobile 6.1 phone with registry settings modified to up the bitpool setting. Honestly, they sound as good as a pair of wired phones. But they sound absolutely awful when paired to my Evo, with unbearable artifacting apparent on high pitched sounds (like cymbals).
Also, how's connectivity with bluetooth car kits? I've got the buletooth option in my Mitsubishi Lancer, and have to manually connect each time (which is a pain). My other car has a Pineer AVIC D3 with bluetooth and the Evo auto-connects every time, also A2DP works on it, though, again, with poor sound quality.
Yes, it's true. I don't have a very good bluetooth A2DP headset (i bought it mainly for phone use, i don't actually use it for A2DP much), so i can't speak to just how good it can sound on CM7. But I can tell that it definitely sounds leaps and bounds better on CM7 than it does on anything else.
That's great to hear. I'll consider moving to CM7 once they get the 720p video recording fixed. It'll be cool to have my Nook Color and my Evo 4G running the exact same ROM.
I found this thread trying to solve this problem. I've found the opposite, the sound quality on CM7 is horrible. The music sounds like a CD skipping. Btw I have a set of plantronics BackBeat 903+. The quality on newer sense roms like synergy and kingdom 1.3 is ok, pretty good inside, and a little spotty outside. I think because the problem changes b/w roms, it is rom specific and not the evo, although I don't know what the best case scenario would be. If anyone finds a solution, please let me know!

Sound is the fatal flaw of the G3

I really like this phone, everything about it is great for me EXCEPT the sound quality. Anything that has to do with the headphone jack is an absolute disaster.
First off I have not experienced the dreaded AUX problem but I have experienced random pausing and skipping - as if I was pressing music controls on my headset - both in my car and on my headphones. I think a headphone jack is starting to wear?
Next I have experienced terrible distortion and static in the left channel, that was until I rooted and Installed Viper4Android. While the problem didn't go away entirely its much better than stock.
Im using my g3 with 3 or 4 devices....
My Acura's line in with Subs/Amps ect.
Shure SE846 In ear monitors
Fiio e6 amp (with the shures, sometimes helps sound quality)
Bluetooth to my Bose Soundlink
The flaws of the g3's sound output are noticeable on any of these, even the bluetooth soundlink and ESPECIALLY, on the SE846 direct.
I created this thread because I dont know what to do, its apparent I am an audiophile and care about my sound quality and youd think Id invest in some sort of MP3 player (I do have a Clip+ ) but I really enjoy using spotify. Should I buy a DAC and just avoid the g3s sound card all together or call and fight with LG and see what they can do?
Is anyone else having these problems? I have the Verizon Device.
I use Westone's connected through a Sony SB52. I haven't noticed any issue except that I like Sony's Walkman app better on my Xperia than LG's player.
I'm fairly picky about music quality and I haven't noticed any issues at all with my HD419s (the only headphones I have right now). Audio quality through aptx bluetooth directly to a car amp and polk component speakers is as good as one would expect too. No skipping or pausing with LG's app. Is that happening when your screen is on? Try turning it off, maybe it's a screen issue? Or maybe it's a glitch with the app you are using? The only problem I had with it was how quiet it was with headphones but the fix with root worked well.
There are several threads about the strange hissing sound - which I also got myself. LG has told me that they're working on fixing it and that it's a known flaw in the current ROMs.
I just got mine and I think this is the best sounding phone I have ever heard. Of course my expectations were very low after my experience with Apple and Samsung.
This opinion is coming from a very jaded HiFi gearhead so your mileage may vary.
The problem I'm facing..
There is noise+distortion+hissing during call
And when headphones are connected I cant understand or listen any thing I only hear wired noises..
Any fix guys ?
Dont know if its technical or software based issue
The sound quality has been noticeably bad for me using headphones also, bluetooth isn't too much of a problem and works fine.
I just got my headphone jack replaced free from LG (as it was doing the random skipping thing) - I quoted that it was a known problem (i mean look on XDA for all the threads) and as my phone was under warranty, i flashed stock firmware and sent it back - when i got it back in 48 hours it was replaced and working. They even cleaned the screen for me lol.
I don't use a headset, only headphones, and the quality is most noticeable on my sennheiser hd800s, but also on my beyerdynamic headphones. Install Viper audio and it improves slightly.
I got mine replaced today as well.
New phone bingo !!
