Having heard from the DTX 501P, I was very curious. According to advertising promises should be a portable, foldable headphones without the typical middle sink, with crystal clear and strong bass sound. To make a long story short, the sound blew me away and I am quite accustomed to good sound. The sound is very clear and unobtrusive. The bass strong and clean (no bass monster). Highs and mids also very clean. He manages to build even a small stage. Processing leaves nothing to be desired. The headband is reinforced by metal. Everything is very high quality. The padding in the headband and the ear cushions are very soft and do not push. He is wearing glasses, like me, most suitable. Only the accessories supplied is extremely spartan. The delivery is next to the headphones a very stable hardcase and an adapter for airplane and that was it already. With this small headset Beyerdynamic is a really good product succeeded the K450 / 451, Q460 far can the Sennheiser PX series and AKG behind. 1000% owned buy recommendation!
