The integrated battery lasts a long time (I have not gotten himself in transatlantic travel empty), but you can not change it, unfortunately, and produced so forcibly sometime unnecessary waste.
With an empty battery the headset to function as a normal cell phone headset, so you can sit not suddenly without music there.
The attention button amazed cabin crew repeatedly. One has the sociophobia plugs in the ears and can become aware of "coffee -? With milk and sugar still a desire" easily respond.
It would be desirable an integrated player control as in the QC20i versions for the iPhone. The excuse that each Android phone manufacturers do their own thing here, does not count in my eyes. The QC20 has a USB port, which is indeed used only to load, if you would but add a little bit of "intelligence", then you could easily accommodate a configurable player control. Perhaps Bose works here sometimes after a little.
