Here is the link through which I originally purchased them on Amazon. Looks like they currently retail for $125 new with 4 stars on 800 ratings. I found their sound quality to be superb, but I have very sensitive ear anatomy and after wearing these for a couple hours they would start to make my head hurt. Other users of the headphones don't seem to suffer from this issue. They still keep a bluetooth charge for several hours. They've probably only been used for 50-100 hours cumulatively.
