I have a pair of HDJ-1000s and although they work perfectly at home, I can't hear my mix properly while at a gig. I do mobile DJ type stuff and as such, don't have a booth nor do I have monitors. My main speakers are usually 2-4 feet in front of me (obviously facing away from me towards the dance floor). It just gets so loud that my headphones, even when cranked to full volume, can't overpower the outside sound. I find this a bit scary because when I turn them up that high at home, they get too loud for comfort. The pads are a bit worn on the headphones so I'm wondering if this may be the problem.
Is this a normal problem or are there other headphones out there that do a better job of noise isolation? Is there somewhere to get replacement pads if this is the likely culprit?
