Does anyone know of a BT earpiece that I can use not only for calls but for also listening to MP3's on both the 8800 or 8300 Curve? I have the Jawbone and Jabra 250v but retired the Jabra due to the pain that it causes from wearing it for long periods of time. Sometimes I like to listen to some music that I have on my card off my BB during the day and it would be nice if I could with the same earpiece that I use for phone calls.
