I thought these were going to be the best heaphones,I wanted them to buy the greatest, I was dissapointed and was contempt with them. For a while until I realised they were garage and I sold themWithout the "bass" they are [...] and uselessI parenthesize that word since you are not getting genuine bass. Bass should not be powered by batteries, the subwoofer is just a fake label.You really get loud vibrations picked up by drivers, hence why you need batteries. You get a ringing sensation, it will itch the first time.I think skullcandy should sell vibrators not headphones.Overall they are relaxing for a while but you realize the sound quality does not keep up with the bass.I reccomend these 70 dollars be spent elsewhere, try them out for yourself before you buy them I know tons of kids who love them, thus why I sold them.Worth 20 dollars If you ever wanna buy these, either way there's no reason, Sony has xb500's if you want genuine bass.
