The decision to buy the Canadian headphone PSB M4U 2 is not easy for me. I have even honestly admit that my company PSB previously was not even familiar with the headset manufacturer. The search for a suitable for my Höransprüche headphones began by listening tests in specialist shops such as Saturn, Media Markt & Co. But could convince me really none of headphones offered there. So I continued my search on the internet with the study of test reports and buyer reviews continued and came one and the same product on always new alternatives, but also on some very contradictory statements concerning sound quality, what my decision not facilitated. Step by step, I reduced the selection by setting a strict price limits, its own criteria and level the test results and various assessments. Coated adulation I was just dropping like negative statements due overstated requirements under the table. In the end, my decision was to try it with the PSB M4U 2. And I must say I have not regretted that decision !! As has been written in other reviews a lot more detail to the sound, I shall confine myself here only on a verbal statement: The sound is well-balanced and neutral, neither bass-heavy nor the heights are exaggerated and annoying. Why I will not forgive 5 stars? Actually I wanted to deduct only half a star; since that did not work, it was finally 1 star for the aesthetic to my mind a little too "clunky" failed bracket. The comfort is very good.
