Query: AMAZING SOUND, bad wiring.

Skullcrushers are like an orgasm for your ears. The sound quality rocks and the bass is unreal! When I have them on i hear very little outside noise (like maybe muffled sounds, but nothing you can really make out), but with little volume the outside world is completely gone! They're great at the gym and work great if you're in a public place and want to zone out in your own world. A must buy if you're a music enthusiast! The only problem i have with them is that the wiring went bad after a few months. if i hold the wire that plugs into whatever i'm playing music out of just right i can hear them just fine. Otherwise, the sound cuts in and out if that. Either way, i still highly recommend these!
