Query: best buletooth

this is my 3rd samsung wep200, i used 3 other bluetooth from different company, but did not work for me. samsung has most clear and loud sound, and you can control the volume easy, it's amazing that how this tiny thing work so well.only downside is your inner ear might hurt a little for 2 or 3 days.
