Sennheiser HD 25-13 is an on-ear DJ/monitoring headphone with an impedance of 600 Ohms. I never found any numbers for sensitivity, though. Or rather, I found a lot of conflicting data: some websites claim 120 dB, others 106, and others yet just indicate a vague "more than 92 dB". The manual...

Hi all! Just got my hands on a pair of ESP/950's. They will definitely become a mainstay on my desk. This is probably the only headphone I have ever tried that fully encircles my ears without pinching or rubbing any part of them. The long-term listening comfort is beyond compare, and that's...
