> K750i: Stereo Bluetooth Headsets?
Bookmark topic
There is an article in the current Personal Computer World magazine (p21) saying that Stereo Bluetooth headsets to a new standard called 'A2DP' (Advanced Audio Digital Profile) are starting to appear. These have a data-rate capability of 3Mbits/sec, and should be OK for music. It says in the article that the W800i is A2DP-enabled. Doesn't this mean that the K750i is A2DP-enabled, as it can be flashed to W800i? Does anyone know anything about A2DP headphones, or even have a pair that they can tell us about?

I don't think it does. Here's the list of Bluetooth profiles supported by the K750i:
•Dial-up Networking Profile
•Generic Access Profile
•Generic Object Exchange Profile
•Object Push Profile
•Serial Port Profile
•Handsfree Profile
•Headset Profile
•Synchronization Profile
•Basic Imaging Profile
•File Transfer Profile
•Human Interface Device (HID) Profile
•SyncML OBEX binding
•JSR-82 Java API
The details are available in a PDF available here:

Isn't that the Headset Profile? (not Handsfree Profile)

I don't think the headset profile is the same as the A2DP profile. According to the Bluetooth V2 specs, A2DP is mentioned in the list of available profiles as well as the headset profile...
That suggests to me that they are seperate profiles...

Headset and handsfree profile are differnt from A2DP (Advanced Audio Delivery Profile).
A2DP is relatively newer and is included in BT2.0 specs.
AFAIK, Neither K750 nor W800 has implementation of this profile. As for talking about support, this is a totally software implementation issue so theoretically above said phones can have it in future. But at the moment that is not the case and I really don't see it happening. The way commercial companies work, they will include it in say K800 or W850 or something

it is highly unlikely to be added to a future firmware. SE rarely adds a functionality upgrade to firmware updates.

This says it's compatible with the K750i, FWIW. Looks very temptiing.

It also lists the K700 which is definately not compatible with it. It will probably work as a bluetooth headset but not to listen to music or in stereo.

bluetooth can only just handle 2 way conversations, i doubt a high quality audio track can be seamlessly streamed via bluetooth without comprimising battery life/and/or/quality
