Replying to Burton RED Audex Audio Earpads

Hey guys, I have the Burton RED helmet and I was thinking of upgrading to the Audio Earpads because the iPod headphones are a pain to use when you're with buddies and want to talk/listen once in a while.The earpads come with automute and volume control on the cord you can use with gloves on.

I don't see these very often on the mountain and I was wondering if anybody here has them or has used them and can comment on the sound quality of either the regular audio ones or the more expensive subwoofer ones?

Thanks.
