I've gone ahead and disabled 2.4ghz band on my wireless router, this has not resolved the issue.

I recently purchased a pair of HS70s from amazon, suddenly today I've been experiencing issues involving Crackling / Popping and audio cutting out. I've uninstalled the iCue software, and this didn't resolve the issue. I've updated the firmware, nothing. I reinstalled the drivers as Windows provides, also didn't fix it. I'm not sure if I should RMA them, if this is hardware or software. Can a wireless router cause disturbances with these headphones? Like if they're on the same frequency? Thanks.
