Vista A2DP

Hi,

I recently bought some Sony DR-BT20NX headphones and now I have
couple of questions.

I've managed to successfully pair them with my Lenovo T61 laptop an
have connected and got sound through them.

My issue is, the sound is rubbish!
This could be just the way it is, but I have nothing to compare i
with.

So my questions are:
How do I tell if these headphones are using A2DP?
They are compatible with A2DP but from what I've read about A2DP an
it's loss less sound quality I was expecting it to sound better tha
this.

More evidence to suggest it's not using A2DP...
I went to the sound dialog in control panel.
Selected my bluetooth headphones - hit properties.
Choose the levels tab and hit balance.
I set 1 to zero and 2 to 100 - thinking this would give me no sound i
1 ear and full sound in the other.

Both headphones still play the sound and both at the same volume.
Clearly this isn't 'stereo' so either I'm not using A2DP or the level
and balance thing in control panel is for something else?

I'm going to stop now, before my ramblings take over.

Any help or insight would be really appreciated, thanks in advance.

Quality help, many thanks Mike!

You actually think Sony make a pair of headphones that are onl
compatible with 2 other bluetooth devices? I take you don't work i
product design!

If you look closely at the link you sent me you'll see that the
products listed are infact only 2 (with 2 listings each).

I don't know what Sony are doing with their 'Compatible Products' pag
but if I could point you to the 'Technical Specifications' page you'l
see that these are just a bluetooth 2.0 device that supports th
following profiles...


- A2DP
- AVRCP
- HFP
- HSP


As a side issue, when I got home last night I managed to pair m
headphones with both my g/f's Sony Ericsson mobile phone and her Son
Vaio laptop.
On both counts I clearly got a stereo connection with sound quality
was happy with (pretty good all things considered).

Now clearly, this could be a case of Sony toys playing well with othe
Sony toys - but I thought bluetooth was an open standard?

So, to restate my question (all be it a little differently) - ha
anyone managed to get:

A T61 running Vista to connect to some bluetooth headphones and givin
stereo quality sound?

Many thanks,

CA

I think that the item in question has been designed specifically for use on
a small product range and if it works on others, then count yourself lucky..

You need to contact Lenovo support then. Maybe it is a simple as not user
the correct Lenovo audio driver..

Mike,

I'm sorry if this is disrespectful - but honestly - I am astonished a
your status as an MVP!

I work in IT and I had (and still do for now) a really high opinion an
level of respect for MVPs - I appreciate how hard you guys work and ho
knowledgeable MVPs are.

So I'm just wondering if you've not tried to comment on a subject yo
know little about here?

Bluetooth and A2DP are open standards, so if a manufacturer claims t
have a product that is compliant - then it simply has to work with al
other devices compliant to that standard - end of story.

It seems ridiculous that sony would bother to list compatible device
for these headphones, as there are literally hundreds (if no
thousands).

Anyway, as a quick FYI - I've fixed it finally. So I now have som
bluetooth sony earbuds that work with my gf's mobile phone, my vai
laptop and now my lenovo t61 - none of which were listed on Sony'
compatible products page!

Maybe it's just my lucky day, but all in all it's a right result! N
more will I strangle myself on my headphone cable when I'm sat at m
desk.

As for how I did it - incase this turns up in someone elses googl
results....

I uninstalled any device that mentioned Bluetooth in the device manage
and downloaded and installed the ThinkPad Bluetooth with Enhanced Dat
Rate drivers from the Lenovo support site.

Now, if I look in control panel at the Bluetooth Devices, on th
hardware tab I have 2 devices listed.
-Microsoft Bluetooth Enumerator
-ThinkPad Bluetooth with Enhanced Data Rate.

Next I paired my headphones with the laptop - this is pretty straigh
forward although the exact details will depend on the headphones yo
have.

So, having paired the headphones they appear in the Devices tab in th
same dialog as above (Bluetooth Devices).

Further to this, and this is the bit that tripped me up, if you clic
on the Audio tab in that dialog you should see the device listed and th
services/profiles it supports.

I have bluetooth stereo audio and bluetooth hands-free audio.

By default, my device was connected via the hands-free audio.
This profile is basically for your stereotypical (no pun intended
it's not stereo) hands-free device for a cell phone. It provides mon
sound at 8khz quality. That's fine for a phone conversation - bu
utterly rubbish for listening to music - it sounds like your listenin
to music down the phone!

The other option, bluetooth stereo audio sounds like it would do th
job. However, initially this didn't work either, it wouldn't connect.

Through trial and error I found that if I turn off the option t
'Connect to a stereo headset only if it supports SCMS-T conten
protection' I can connect to my headphones using the stereo profile.
have no idea what SCMS-T is, I know it's not even an option on the sam
dialog on my Vaio, the fact is, it works without it and that's goo
enough for me.

Finally, it's worth mentioning that you also have to go to the soun
applet in the control panel and set your headphones as the defaul
device on the playback tab.

And that's all there is to it - my bluetooth headphones are playin
nicely with my T61 just as I'd expected them to

I was going on information given on the Sony site initially. I too found
info that suggested going to the Lenovo website, hence my suggestion in the
second post that you do likewise.

Perhaps you should suggest to Sony that they change the info given on their
'compatibility' page instead of complaining at me..

Just wanted to say that i was thinking the same.

Your post really helped me out though. Thanks!
