They have worked very well for me. Blocked out all sounds around me and the sounds that came out were great. I also really like her looks. But before my warranty expired, the switch broke. I emailed the company through the Revain Marketplace and initially thought they would take care of me. They said they were "more than happy to help (me) with a replacement for these headphones" after I confirmed my order number and address. But that doesn't seem to be the case. I also ordered another pair of these headphones but they weren't as good and I left a review to reflect that. The Symphonized team indicated in their email (about my replacement headphones, which I originally asked for) that I might consider updating my previous review. When I said the issue I was having with another headphone is still a problem, they responded again and again asked me to update my review "at least for our support team". without headphones and upset.
