I have the T50 P ordered after reading the Amazon reviews. Previously, I had heard of B + W in the search for a natural-sounding headphones, inter alia, the two models. These headphones sounded very transparent and rather flat compared to the T50 P for my taste. The T50 P makes particularly good at shooting with natural instruments (eg jazz trio) really fun. The piano sounds warm, crisp but not the bass and the drums wummernd just like a drum - tested with the CD Vägen from Tingvall Trio. The foreclosure against extraneous noise is also very good. The processing of brushed metal is very noble and high quality. Only the fact that the headphones are not really small fold, is a slight drawback. But as I said, I was looking for a good set of headphones ...
PS: Before first use, I have the headphones can also import approx. 24 hours.
