Sorry if i'm going off the topic here, but is there any way at all to play sound from the media player application to any bt headset?
I don't care if it's stereo, nor if it's high quality, as i'm only listening to podcasts (talking) and mono audio books.
I have SE P910a. Some have suggested a bt transmitter + headset but the point is to use the phone's bt.
Thanks for any replies. |

Ok... a firmware upgrade will NOT work unless the BT chipset itself is already BT v.2 compliant. That would be like saying a software upgrade will give me Hyper-Threading on a P-II CPU. You need BOTH the hardware and firmware to support the new stereo audio transmission.
And yes, the audio quality sucks. Imagine the crappiest headsets you can buy... then imagine that the jack was rusty and dirty and you kept twisting it around to get a solid connection (ever experience those crackly sounds?)... then you'll get pretty close to BT stereo audio.
Now, if you're the type who can stand to listen to MP3s encoded at 128kbps and lower... then you may not notice anything bad about the new BT stereo headsets.
Logitech has a white one... if you want a black one, you can get Logitech's "HP" branded one.
I'd say these things are better off for games where audio quality isn't that big a deal.
I'm wondering if these BT headsets have a memory buffer. Quality would improve a whole lot if they added 1MB of buffering so that the headset would have time to decode and add some DSP corrections

It's quite strange !
In K750i white paper on developper SE site, we can read :
"The K750i supports Bluetooth specification 2.0."
Page 27 in this document : http://developer.sonyericsson.com/getDocument.do?docId=70824
So the K750i should/may support A2DP profile if its in BT2 specs, isn't it ?
BTW its not in Profiles list on page 28 ...

Although I have a SE Z800i, my phone is very similar in terms of specs to the K750i (apart from the 2.0MP camera on the K750i and the 3G capability on the Z800i, obviously), and so I might be able to shed some light on the question of music playback through bluetooth headsets:
I have a Motorola HT820 stereo bluetooth headset for use with my phone, which works very well as a handsfree, but it seems that there is no way that the phone can be made to play music through the bluetooth headset. When a regular (corded) handsfree is plugged in, the media player automatically plays music through the handsfree; when the bluetooth handsfree is connected, the handsfree functionality is identical to the corded equivalent, but the music player plays music through the phone's speaker only. This would appear to indicate that the Z800i does not support A2DP, and I'd consequently assume that the K750i would be the same. |

Just because the BT2.0 specification includes a profile doesn't mean all bt devices will support all profiles. You wouldn't expect a headset to support the hid profile for example.
I don't understand the need for discussion. The K750 white paper doesn't include A2DP in the list of supported profiles, so why would anyone expect that somehow magically K750 gets A2DP?

Have you tried using a Bluetooth headset with a Nokia? All sounds are transferred to the headset once connected, music and all. And yep, even key tones while pressing buttons are heard from the headset. |

So nobody brave enough yet to have bought one of the many stereo BT options available and try it out? |

those options are not available for the K750, which doesn't support the stereo bt profile.
Forget bluetooth if you want wireless stereo from your K750. The only option is rf (plug fm transmitter into hpm-70 or mmc-60 and send stereo to a fm radio). All phone sounds come through, but the mike isn't wireless, so you have to use the hpm-70 mike to talk.
For example, you could have the hpm-70 mike clipped to your lapel with the fm transmitter lead plugged into the socket. The cables would run down to you pocket/belt where-ever you put your phone and the transmitter. In your other pocket you'd have a small stereo fm receiver tuned into the fm transmitter, with a headset plugged in and leading to your ears.
Sounds complicated, but it works, I just tried it! But in truth, it's to cumbersome to bother with. However there was one unexpected advantage I noticed - the fm radio was capable of blasting the sound even louder than the K750 itself is capable of.

that seams a little over the top, why not just plug the handsfree kit in, a lot less boxes to fit in your pockets.
Good idea for driving as it provides a handsfree without actually being wired to the car and saves using a bluetooth car kit.
I use the home made hpm-70 for this through the car speakers and means the call actually come through the car stereo and the hpm mic picks up my voice.

I agree it's over the top!! I didn't suggest this option with any degree of seriousness. I was just offering a "proof of concept", and also out of perverse curiosity.
I'm sure the dude's concern with the lack of stereo bluetooth is because they would enjoy the convenience of a having no more than a bluetooth stereo headset on their head and their phone in their pocket with no wires to get in the way. My "wireless" solution certainly doesn't achieve that (more wires than a wired handsfree ). However, if you needed, for whatever reason, to send the sounds on your phone in stereo wirelessly to a set of headsets (or a stereo system), then this is the way to do it. Of course as I mentioned, this setup doesn't offer a wireless mike, only wireless audio output.
If you rewired the hpm-70 to provide a jack for the mike as well, you could use two fm-transmitters. One to send audio from the phone to an fm receiver, and another to send audio from a wireless fm mike to an fm receiver plugged into the modified mike input on the hpm70. Technically it is wireless, but we are now carrying a phone, two transmitters, two receivers, and about ten miles of cable
Incidently I agree with you about the car, I have an fm transmitter actually installed in the vehicle, with a lead coming out from under the dash from the fm transmitter for audio input. I just plug that lead into the hpm-70 jack and away I go. No batteries to worry about for the fm transmitter, and I have a car charger that can piggy back the handsfree, so my phone is on charge whilst driving.
To speak I just reach for the hpm70 mike, or clip it to my lapel whilst driving. I don't do it so much for the wireless function (it's not really wireless, since the transmitter is installed in the car), more so I can listen to my fave music whilst driving.

I asked the Support HelpDesk Of SonyEriccson Belgium,
They returned the following mail:
The k750i is FULLY compatible with A2DP, AVRCP 1.0 en GAVDP 1.0
It should work without any problem!
