Query: Poorly designed, uncomfortable, keep falling off my head - getting annoyed every evening (doesn't charge well either).

Don't sit well on one's head and not that comfortable. Can't relax in the evening when I want to watch TV. Doesn't recharge well and overall poorly designed. Spend an extra $20 and buy a better quality Sony set, which I had for years and was really happy with. Am going back to them.
