Anyone else the same experience? Contrary to almost every other WM device I have used in the past, the voice sound quality both on BT headsets and on parrot carkits is way below par. It sounds thin and metallic.

When using the speaker on the device itself (held up to your ear) the quality is excellent, so to me there is a major flaw in the the BT implementation on the Kaiser. The x7500 sounds way better, so it's not the OS itself.

Finally, someone else with good hearing :)

I have exactly the same issue. Even it's tolerable but is some situations it's very hard to hear the other party. Doesn't matter what headset I am using - Nokia BH 900, Jabra JX10 2 or Jawbone - they all sound thin. I really hope that there is something in registry that can be changed to resolve this. Or maybe a different DLL. In fact, this is the only complain that I have about Kaiser. I've tried this suggestions but none of them worked unfortunately.

Increase Audiogateway capability:

HKLM/SOFTWARE/Microsoft/Bluetooth/AudioGateway/Capability
(Dword:69)(Default is 37)

[I'm assuming this is a bitrate setting, but not sure how this differs from those above]

4-Change the Bluetooth channel from the default:

HKLM\Softare\Microsoft\Bluetooth\Device

From there open the subfolders and find those labeled channel. The DWORD key value is the channel number. Change the number to something other than the default.

[i've only tested up to channel 7 because I'm not sure how many channels there are. This seems to have improved issues with interference and intermittent drops, but these issues seem to have more to do with where the device is in relation to the headphones than anything else. You'll have to experiment to see what works best with your gear and environment.]

5-Increase the Bluetooth microphone sensitivity:

HKLM\Software\Microsoft\Bluetooth\AudioGateway\Mic Volume
(DWORD:10)(Default:5)

6-Increase Bluetooth earpiece volume:

HKLM\Software\Microsoft\Bluetooth\AudioGateway\Spk Volume
(DWORD:10)(Default:5)

[again experiment to see what works best with your headset and environment]

Ouch. Just came out of an escalation meeting for which I was forced to use the TyTN II for almost an hour over my Sony Ericsson HBH pv705 headset, and I have to rephrase my first post.

The audio quality is leaves not just a bit to be desired, it is just blatantly bad!

That, I feel, is the only *real* letdown of the TyTN II

Have exactly the same issue here. Was using it today in the car using the Mercedes bluetooth kit, and the sound was very thin and tinny. On my Hermes the sound was full and fine.

OK. Now we have to determine is that :

Hardware issue
or

Software issue.

I've briefly used one of the preproduction units back in June and as far as I remember BT was OK. But I can't be sure 100%.

Anyone still using pre-pro units? Please, check how BT headset sounds like.

I really, really hope that this is software issue. Otherwise I am afraid that I am not going be able to keep the unit :(.

Sorry to put this into the mix but I have actually superior sound quality using a Parrott Car Kit and a Motorola Stereo Headset as compared to previously using these devices with my Hermes device with the newer WM6 ROM's.

I have made no changes but just wanted to share my experience.

It's probably due the fact that car kit has already plenty of bass and stereo headset is using a2dp. My stereo BT headset sounds good as well.

Handset itself sounds good, wired handset sounds good. Again, I really hope that there is a way to change something in software that will fix this problem. i guess, we have to wait until device is in more hands and some hackers will find the way ;)

I use the Sony MEX-5000BT headunit in my car in handsfree mode. I've used it with both the Kaiser & Wizard, and I can't tell any difference in sound quality between the two phones in handsfree mode.

A2DP is a different story -- the Kaiser is much better.

OK, this is rally confusing. As far as i know all units have the same ROM/Radio builds. Or are they?

Let's start to put numbers:


Mine

ROM 1.56.405.5

Radio 1.27.12.11

protocol 22.45.88.07H

BT is too quiet and tin.

Same as above. BT sounds great with my Scala 700 earphone.

What type of device you have been using previously?

When you switch from handset to BT headset on the fly do you hear difference in voice quality? Doesn't seems like BT headset doesn't have the same frequency range as a handset?
