I recently bought a new cell phone (Sony Ericsson Z520a) with Bluetooth. I spent a few days researching the various headsets out there, and soon discovered that only a handful appeared to be worth buying -- and all were between $100 and $150, which I did not want to spend. I came across these by accident, and couldn't find any of the negative comments common with headsets in this price range. Granted they're only Bluetooth v1.2, but they're light, have a built-in rechargable battery, are quite comfortable to wear, and have very good sound quality. In addition, the pairing process is quite simple.
