my brother in law get I a set of these and I think they be one of the best accessory I have ever use . sound quality be outstanding , I hear no static even 2 floor down when I be do laundry , and the extra battery charge in the base so you can quickly swap out if you run out of juice . comfortable as heck . I do not know why the other person say they be not tight enough , unless he have a really small head . I think the tension be perfect , but I be a 6 ' 2 '' american guy so you mileage may vary .
