For those who just said "terrible" or "awesome" Keep in mind sound quality is relative to the listeners ear and in my opinion also relative to pricing. For this price point, I can't see where there could be much or any improvement of sound Q on these headphones. There are of course shortcomings in the high end and the low end, BUT it's very very good for the price. I will just leave it at that. If your wanting to know if it's worth the money, the answer is yes they sound brilliant for $20 Bt headphones.
