Have to compare and find the best for me headphones, the Beyerdynamic T1 for several hours by the ears and can already announce the following statements about this: - In comparison to Sennheiser HD 650 ... a very different acoustic world, the comparison is not eingentlich admissible as .. old apple fresh from the best growing region. - Compared to the new Denon AH D 2000 and 5000 .... turns out that it is significantly more expensive though, my em- pfinden to acoustically but not better. - The light voice coil with 600 Ohm required relatively high voltage signal from the amplifier (which is the Beyerdynamik headphone amplifier A1 but not a problem) and tends to the upper midrange, especially in Women's voices, something sharp to sign. For instruments reminds me of the less unpleasant. - In the lower bass range, for example Orgelpeife with 8 Hz, him of the pressure that the two aforementioned Denon KH too much missing have. The bass can weaken, by reducing the contact pressure only in the Denon`s. When T1 can be which however does not raise, by enhancing the contact pressure, which would also reduce the "endurance" of the T1.
- Conclusion: I can not confirm the T1 all the sound quality that the manufacturers him understandably guaranteed. It all depends on with what measure you measure. In a much smaller price the judgment would look for better from him. Otherwise a perfectly acceptable headphones with consistently good up almost very good acoustic abilities.
