INTRODUCTION: The fact that a lightweight headphones like these not comparable with Hifi surround headphones that cost many times must be clear. Compared to other headsets in its price range of Sennheiser PX 100 is voruas in many ways its competitors in my opinion clearly. KLANG: Is headphones in my ears at this very natural, to be called balanced mids, clear highs and quite capable of delivering powerful bass despite its low weight. However, he is not an exaggeration bassy like many other similar headphones, which I very much appreciate about him. COMFORT: The PX 100 is amazingly easy and very comfortable to wear, after some time you forget even that you actually wearing a headset. The length is easily adjustable and the external pressure is minimal at acceptable stability. PROCESSING: Perfectly processed and works stable. You can virtually fold and stow away in a box supplied him even. As a result, the transportability significantly increased. However, I have already merged him quite a few times and just squeezed in the backpack - it seems to make out anything. DESIGN: In my mind, plain and unauffällitg, according to the purpose APPLICATION: Glossy suitable for listening to music on laptop, to other portable devices, but brings quite the sound of a good middle-class facility amazingly well over. Shortcoming (S): The only drawback of this headset is in my opinion the short guessed cable. With 1,4m Länage that's for sure ideal for those who use it only with portable devices. But not for those who also use it at home with larger systems. Nevertheless, an extension cord should remedy this. CONCLUSION: A many ways successful lightweight headphones with an optimal price-performance ratio of the Sennheiser. We recommend!
