content: I use these to watch TV when family is asleep. It works well most of the time. Sometimes, one day out of week, there is too much statics, clicking and hissing. Most of the days it's totally fine. Definitely not location-related. More like the weather of position of the Mars.I wouldn't listen to hi-end audio in these, but for TV it works great. And recharger base is nice and easy to use.
