Haha reading all this hate and crap about batteries... Since I don't sleep in a bed anymore I have moved things around, now I have my speakers by my head, and I listen to these loudly... Well loud enough were u can't hear it outside of my room. So volume is great, and I just dim my monitor for bed, so.... I love it.. 😆😆😆😆😆😆😆
Don't forget the part that says "if you don't use headphones, you will not experience binaural beats" :)
