Summary: I bought this on the basis that it was Sennheiser. First up.. getting this out of the box.. Almost impossible, apparently you have to cut two plastic strips on either side, but this really isn't obvious - until you realise this you'll seriously struggle.
Summary: I got these on a black Friday deal so heavily discounted. The sound is better then previous quality ear phones I have had, and they are the most comfortable. However, we're talking fine margins.
