I use the Bluetrek G2 and it works very good. The sound quality is very good and its a very light headset. You can wear it for long periods of time and forget that its there. you can go to their website
www.bluetrek.com and check them out. It cost 54.99. The battery is also one of the tops in the market right now with 9 hours of talk time and a standby time of 400 hours. The exact weight is 12 grams.
