Really please with the headphones I purchased for my partner, good sound quality

I've been using a set of 'cheaper' Sennheisers for years until they finally gave in to the abuse I subjected them too. Decided to try some new Pioneers those were uncomfortable and broke within a couple of months (I'd taken really good care of them too). Decided that I'd follow the herd and plump for these expensive ones. Sound is really nice and isolation is good. You can easily hear what you are doing in loud venues. Build quality / design is really good too. The way the cable is clamped to the headphones and is replaceable is brilliantly functional. Might not meet the apple school of design but it means that the life of these can easily be extended. I expect these will last much longer than my previous Senny's - over 10 years.

Awesome industry standard headphones used mine at many clubs and the out perform the other brands all day long

Amazing sound quality crystal clear.

All I've read and heard about these headphones is true - great sound, comfortable and robust. I call it an investment not an expense !
