This is the first set of headphones I've come across with Bluetooth and noise cancelling. Usually, when a set of headphones utilises either of these technologies, you would expect to take a hit on sound quality and/or bulk in the old days. Sony has just proved that is not true anymore. The headphones are light, comfortable, a breeze to connect with Bluetooth via NFC, and best of all the sound quality is surprisingly good. I use them on the bus commuting to and from work, and they do a decent job of minimising bus noise while maintaining sound quality. The only thing I wish it came with is a nicer case, but that is a very minor complaint overall. Highly recommended.

The sound from these headphones is very good, even better when using wired. They are comfortable to wear and lightweight . But, if you intend to use them with an IPad to watch videos or to use music notation software be prepared for audio lag, sometimes so bad that it makes the video unwatchable. There is no problem just listening to music.

Very good I not sure on battery state and feel it could catch me out
