These headphone are brilliant, really comfortable to wear for long periods of time.
I've had long gaming session and used them via blue tooth and have had no drop offs. they last a long time too 7 hours and then I got tired but they claim upto 10 hours and I can believe that.
to pair is just like all bluetooth headphones and controling the fuctions are simple. if power does die you can use the aux cable suppled that also had volume controls on too.
I really like these headphones and am pretty sure if you buy them you will too.
