sony headset.

good point.The sound is stunning. used in the train and it is true that we are in a bubble. it works with the terrible Z3. it can make hands-free kit.
Bad points. noise reduction works only with compliant devices from Sony.
Prices for Sony could have delivered a storage bag.
a little big.
no remote to control the phone. a button for answering and for the volume would have been welcome.
ultimately good helmet but bad pedestrian kit.
