I have been using pocket pc for the past 4 years and these days I always use bluetooth headsets to make and answer calls. I have a good collection of bluetooth headsets.

This is a Nokia headset, good quality reception and good battery life, but bit bulky and not stylish.

This is a Sony Ericsson headset, but the reception is very poor and I really regret to buy this. The advantage of this headset is that its very small and fits well to my ear

This is an excellent headset, very powerful and light, good features and I really like this. One problem I find with this is if you accidentally press the multi-function button, it will redial the last number.

The best that I have, Nokia 800BH, very powerful, like, very clear sound, I highly recommend this
