Skull candy Crusher Headphone

The bass on this thing is phenomenal if you crank the bass all the way up and listen to a good song with good bass the things will literally shake on your head while at the same time sounding really good, your probably thinking "oh that's totally BUNZ It can't be that good." Well trust me it is, still want more evidence look em up online, see some reviews,
Oh and by the way it only needs one AA battery, it works without it but if you want BASS just pop one right in
