da_emerson,
It depends on what you need and want in the headset. There won't be a wrong one as long as you get a bluetooth headset. That phone would support a stereo headset so if you will be listening to music, etc and want a stereo headset then you should narrow your search to Stereo bluetooth headsets. Nokia makes some but other makers do too.
If you want some input on which can be better, etc then it would help to know any needs or requirements you have. In general i don't have a specific one to recommend but suggest you test yours for comfort and fit with your head and ears. Also it can be very important to have one that has a sensitive mic, that will also ignore background noise, and good speakers. These factors can be harder to determine and even be subjective though so it may be good to buy from a location that would let you return/exchange.
Let me know if you have any questions or need more information.
