Title: Good earphone
Review: I use this to go with a treo 700w, and now a blackberry. It is small and light. Sound is good. I like the battery recharge option most. I also like the fact it has several adapters so I can minimize the number of adapters I have to keep and carry. I wear glasses so there is no ear hook interfering with the glasses. Occasionally while driving, the other party complain about the ambient noise but somehow it does not happen all the time. I never had other blue tooth headset before so this is not a comparison.Be careful however, with the similar product numbers Plantronics use. A coworker bought another 640(??) and turned out that one does not have all the adapters.
