T-Mobile UK MDA Compact & Poor Audio

All,
I recently got a T-Mobile UK MDA Compact and when I attempt to make a phone call the audio in the ear piece is very poor and plus the other person seems to here a echo or if they speak loud to me the ear piece seems to distort. Also with the sim card in or out when I switch the phone on and place it over my ear I can some electrical interference coming from the ear piece.
I spoke with T-Mobile who said they are not aware of this problem but they have now sent me 4 replacements all with the same problems.
I used to have a old Siemens S55 and the audio conversation on that is 10 times better, the voice of the other person is clear and just like talking face to face with them.
The MDA compact is extremely poor for audio conservations using the handset but when I use it with my Sony HBH600 bluetooth headset the audio is much better, has anyone else experienced this problem or is it just my bad luck :-(
Thanks
Msuk

I have the exact same symptoms in my Jam. The audio quality is awful. I think a lot of Jam owners are in denial about this.
YOu should still have a return period open. If the quality is that unbearable, return it and get a different phone. I sure wish I had done so, instead of thinking that I could solve it with firmware updates.

My audio was poor before firmware updates also.

Low sound quality with 6700 and Moto HT820 headset

Hi All,
I am new to the forum. I have owned a PDA phone for about a month, a Verizon (HTC/Apache/UT Starcomm/Audiovox) XV6700. It was rebadged so many times, I have no idea who really made it.
I read about A2DP Bluetooth technology. I also read reviews of several headsets before purchasing the Motorola HT820 headset.
I loaded up a two-gigabyte mini-SD card with mp3 files, popped it in, paired the headset to the phone and engaged Windows Media Player.
Unfortunately, the sound quality is horrible. It sounds as if I am listening to music played over the phone, as if I am on hold with some customer service call center. I know the headphones are capable of much more because they come with a stereo mini-plug cable. When I plug them into the audio output on my laptop, the headphones come alive with decent sound quality.
I did not modify my registry or add .cab or .dll files. When I paired the headset with the XV 6700, I just checked the "hands free," "wireless stereo," and "headset" options.
Am I missing something or is this the sound quality I can expect from this technology?

Make sure you have the new ROM update for the Verizon VX, and install the Tornado cabs and dll files.

A2dp on xv6700
I have updated my rom, made the Tornado changes, made other reg changes as described in this and related forums - all to no avail. Stereo Sound is constantly clipping. Phone sound is ok.
What else can I try
Feel free to email me direct.

You may want to try another player, like pocket player. Or try another BT stereo headset. If that dosn't work you may want to try getting your device swapped out with a new one. I can't get it to work on my PPC6700, but am waiting for a fix of the EVDO/ring through problem with newer units before I try to swap mine out.

xv6700 a2DP lag
I have already tried the pocket player - no difference. I am also on my second headphone set (albeit from the same vendor).
Unfortunately Verizon will not swap out because an unsupported feature does not work. At least that is what they told me.

Don't worry you are not the only one that can't get it to work.
The bluetooth on the 6700 is not very good, so YMMV when it comes to A2DP. It is a unsupported feature, you may need to convince them the BT is bad, but don't mention the A2DP.
I am waiting for a fix of the EV-DO ring through problem on the shipped PPC6700 with the new ROM before I have Sprint look at mine.

XV6700 A2DP lag problem.
Unfortunately without A2DP "enabled", the bluetooth connection seems to work just fine.
BTW: What is the EV-DO ring through problem?

It dosn't apply to Verizon VX6700, just the Sprint PPC6700.

Low sound quality with 6700 and Moto HT820 headset / A2DP
I am new to posting, be kind please. I have spent a lot of time and research on this problem and I am having some luck and some other problems that there may be some great info on. I do have the latest firmware from UTStarcom (Verizon model) which has AKU 2.0 update. I did install the tornado A2DP I found here and it did not work at first until I found the additional Tor_A2DP_cert.cab file and installed it. It works and seems to be stable, including headset operations. The only problem is sound quality. There is a ringing like high pitched digital noise, my experience in electronics would have me thinking of a bandwidth limitation, or timing issue that would be a result of process priority or something, just guessing! I have the Plantronics 590a stereo headset that sounds great when using the BT with my laptop, so I beleive it is with the phone. The big question, has anyone tried changing the registry settings concerning bluetooth? I see some entries here: HKEY_LOCAL_MACHINE\Services\BTAGSVC and HKEY_LOCAL_MACHINE\Services\BTHIDSVC don't know what they are or what they would do, not brave enough to change them.

have the same problem

I have two BT Stereo headset, 2 different A2DP devices, BT laptop, and a BT dongle and get different results with different combinations.
- Southwing SA505 Bluetooth Stereo Headset (works great with everything, questionable manufacture quality, broke after 3 months of use)
- Moto HT820 Bluetooth Stereo Headset (good quality, but BT functions & sound is problematic)
- Cing 8125 (running Faria Crossbow WM6)
- LG enV VX9900 (vanilla os)
I believe it is just a simple case of both Bluetooth software of your device and headset not getting along together.
The SA505 works perfectly and sound quality is awesome with all A2DP & BT remote devices (including both devices, BT laptop, and a cheap generic usb BT dongle installed on my desktop)
The Motorola HT820 on the other hand is quirky...
Paired to the 8125 - when listening to music, sound breaks briefly (for 0.5 - 1.5 secs) randomly every 30-60 secs. Everything else is fine including sound quality.
Paired to the vx9900 - it unpairs when getting a incoming call & I have to manually pair it back up. Everything else works fine including outgoing calls. Good sound.
Paired to laptop or BT dongle - works perfectly.
in short the only thing that could be done is on the handset side by changing the BT stack or rom.
hope this helps.

Just try MSI Blue Player, this is the only PLAYER which post a high quality sound to my bluetooth ear piece.

VX6700 and Bluetooth
Just as a friendly note, I had the Verizon VX6700 until last week. I had tried numerous bluetooth headsets with it and all seemed sub-par or totally unacceptable. The last one I tried was the Southwing SA505 and was, to say the least, displeased with the sound quality. I shelved all my bluetooth headphones and continued using the Motorola H700 earpiece for phone use only even though it was hard to hear in noisy environments, but was the lesser of all evils. Last week, I was available for upgrade from Verizon and got the LG Chocolate, took it home and put some music on it and used the plug in style headphones for the first day. After getting sore ears from the round-stuff-them-in-your-ear-hole type headphones, I decided to try the Bluetooth headphones again for the mere humor of having spent over $200 on the lot of them. The Southwing SA505 sounded phenomenal on the Chocolate. I then tried talking to my wife driving down the road with the windows rolled down and going 65 MPH, which had always been a problem before. She actually sounded like she was right next to me in crystal clear stereo (which if you have been married 21 years as I have, then you understand what a scary thought that is). I don't think the problem you are having is the headset but rather the phone and unfortunately I have no answer how to fix it, but hopefully have steered you in the right direction of where the problem lies. Good luck to you.

A2DP audio quality

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 !

BT headset + 614C = problem...

Hello you guys...
I'm ahving a lot of problems with my 614c and my motorola BT.
I can't hear a thing... I know that the sound of the PDA is less than perfect, but the earpiece works 100% with other phones... In 614C the sound is very very low...
Do you know if this can be fixed? If not, what is your best BT headset?

Perhaps go to Audio settings ? If you can't hear much , i suppose its rom related i just flashed to some WM 6.5 (can't recall the build now) and incall volume is maxed out but still it was better before,maybe diffrent ROM ?

I'm using a 6.5 ROM but it seems to be the worst of all...
Do you have a BT earpiece? If so, what brand?

I use the Keys Rom and a Sony BT Headphones and works great. Volume sounds fine for music also for calling.

Can you please tell me what sony headphones you use?

sure, the headphones are:
SONY DR-BT21G. You can read about it in this link

double post

My headset sound quite good, despite the volume on the device itself on the standard HP ROM.Using youtube's own app.
Sitecom CN-532 quite cheap.

Bluetooth Audio Quality

(Update: 2/23/10: To replicate the problem, use a bluetooth headset, make a call, then walk away from the phone until you're almost out of range. That's exactly the problem I have when I'm holding the device, it doesn't matter where I am distance wise, the best audio call quality I get STARTS where most phones get when you're too far from the device. Ideas?)
After weeks (3 straight) of searching, I have to finally ask.
Does anyone else have an issue with the quality of their bluetooth connection (calls only) regardless of brand and distance from the phone?
I've purchased nearly 13 different bluetooth devices trying to fix this. Changing the distance from the actual handset (experimenting if there's a different to if the Hero is plugged in or not), the price of the bluetooth unit, what type it was (speaker phone unit only, carkit, headphones, ad2p or not, etc etc), and I still have a poor call quality call.
Reception isn't an issue, I've tried from full bars to almost no bars, and in every instance, when I disconnected the bluetooth and went back to using either speakerphone, headphones, or directly on the device, the noise went away.
You can only hear the noise when the remote party speaks, and it really sounds like the old analog bag phones in bad reception. Is there anything as far as changing settings on the bluetooth to improve the audio quality?

not really. the BT module sends information to the receiver and the receiver decodes that into audio. so you cant really set an EQ for BT with android at least so it basically depends on the receiving unit. while music is playing turn the volume down to 75% on the phone and thats the best quality you will get. im an audiophile and it works for me.

I have a Plantonics Stereo BT.
It works great on my Hero... Much better than my HTC Diamond!

Haven't had any trouble from my Jawbone 1. The sound quality isn't as good as it was on my TP, TP2 or Pre but it's ok. Haven't had any weird noises. But it does randomly disconnect from my Hero. Well the phone says it is still connected but I get no call notifications through it and when I answer, the audio is through the handset. Even right after I finish talking to someone through the BT. Gonna have to chalk it up to the Hero cause I've had no issuse with it on any other phones. Best BT ever in my opinion.

Yeah, I don't know. I have used the Jawbone II, Jawbone Prime, Moto H12, Moto H790, and Plantronics Voyager Pro all with no problems in sound quality, also audio quality is very important to me because I do have some hearing loss. My call quality with the Hero isn't quite as good as with my old Blackberry Curve, but it is still very functional as I use it at least an hour everyday. If you have gone through that many headsets it is quite possibly the device itself.

I don't know, I have 3 Hero's and I honestly don't like the quality of sound on any of them. One of them is just straight stock. I just wish I could get it with a clear quality as my old dumbphones have. I think I've been helped to discover the answer to my question, thank you all!
