I have tried 4 different Bluetooth headsets with my K750i. They all pair without problem. But try using it ..... within the first few seconds of connecting the headset acts as expected (accepting an incoming call and talking to the caller, or making a call using voice dialling). But, wait any longer and it all goes wrong ....
An incoming call can be accepted (i.e. taken off-hook) by using the button on the Bluetooth headset BUT the sound comes out of the phone and you have talk to the phone's microphone.
Similarly, voice dial is initiated with the button on the headset BUT you have to say the voice command into the phone and then the call stays in the phone and can't be transferred to the headset.
It appears that the audio path to the headset gets lost. I had hoped that the new release of firmware (R1N035) would address this, but it doesn't, at least not with the I-tech Clip Headset. I don't have access to the other headsets to try them again at the moment. But I have assumed that since the fault symptoms are the same for all four headsets that the problem is generic to the K750i software.
Bluetooth file transfer works very well, so I know the "wireless bit" works fine.
Headsets I've tried :
I-Tech - Clip Headset
Sony-Ericsson - HBH-608
Jabra - BT200
Bluetrek - G2
Does anybody have a Bluetooth headset that works reliably with their K750i?

In reply to Bart's question : which headsets did you use?
I have updated the first post in this thread to show the sets I tried.

Since upgrading I have only tried the I-tech Clip Headset because the the G2 and the HBH-608 were returned to the shop and I haven't been able to borrow the Jabra again. I had assumed that since the fault symptoms are the same with the four listed headsets that the problem was generic to the K750i.
Bart : Which one or ones on my list would you expect to work? Also, can you please let me know why you feel they should work.
Thanks,

I have the same problems with my G2 on my K750 with R1N.
It would appear that the G2 uses bt 1.1 & 1.2 while the K750 uses bt 2.0

I've been using a comparatively cheap Kingcom Dolphin KM-168 (handed down from my previous T630) on my K750i very successfully (even using voice commands) when it was still on R1L002. I haven't tested it when I updated to R1N035, except for voice calls. I'll test it tonight. I'm not sure if Kingcom is available outside Asia though.
I previously got a(n even cheaper) Popcom BT headset but exchanged that for this current one since the Popcom BT had too much problems with the T630. Most annoying thing was similar to your losing the call to the phone, and I also had to pair the darn thing every time I turn it on!

I've copied this from the K750 firmware thread:
I've just had a bit of a issue with a R1N035 K750i and a HBH-660 BT 1.1 headset.
Basically when audio is transmitted to the headset I got about 5 seconds worth and then the audio cut out. The BT connection is still active, the call hasn't been dropped, and both devices have plenty of battery life.
Switching the call back to the phone continues the call.
Tried a number of BT 1.1 headsets and they all seem to cut out. Tried the same headsets against K750i's with older firmware and they work okay.
A selection of HBH-662 BT 1.2 headsets work with the R1N035 K750i...
So, it looks like R1N035 might have issues with BT 1.1 headsets. I'm going to test this later today with other headsets/K750i's... BTW, I did a master-reset on the R1N035 K750i and it made no difference...
