Low sound quality with 6700 and Moto HT820 headset

[crazziedavey]

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. :)

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.

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.

[budney]

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.

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.

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.

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.

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.
