I think there might be some qc issue with the first batch of black Evos which some customers had experienced with the hissing sound when wired. Over all great product At first when I took these from the box, I thought theyd be uncomfortable and hard to walk in. UPDATE: 2 years later, from being constantly wet, the mildewy stuff ended up degrading the finish on the under-side, and its totally skanky. If I had paid the $79. You cant deactivate ANC on the Bose or Senns, but both do a good job making virtually no white noise even when the music is silent. As you can see, we chose to do our own set up where we allowed space for the pc to be under the structure and have cubes above. Nice color scheme: good fit and price is great! The first order was delivered to the wrong address for some reason (an Amazon dock). NO MORE ITCHING OR RASH!
