Friends, I have been using this Dell Byte (Bluetooth ) head set for 1 year. Here are the things we like. 1. Excellent music clarity - so far best bluetooth music streaming I experienced. 2. Quickly charges and comes for atleast 2/ 3 days (8 - 10 hours of high volume music ) if we use for long hours. 3. Easy foldable design - Even device look big we can carry easily by folding. 4. Even at low volumes you can hear each damn chime/ note in your music :) Thinks I don't like about it. - Mike clarity during a call is not clear in noisy environments. - Not very ideal - if you are planning to use it majorly as a bluetooth mobile conversations.
