Query: Not up to expectations

This new (expensive) head set is very tight. I am trying to be cautious in putting them on or off because they were purchased to replace a set that snapped when being placed on.. As i tried to get used to the pressure they exerted on me I found that they don't hold a charge very well.( after a few hours of evening TV the sound fades and disappears). I will probably return them, but of course that's a time consuming hassle.
