I for one year possess the TMA-1 now. At that time I wavered between the TMA-1 and the HD25, finally I decided for aesthetic reasons for the TMA. The device is kept absolutely robust and beautifully simple. What I noticed immediately and that bothers me repeatedly is the tight fit and the unpadded strap, which is already very unangenhem after half an hour. For sound quality, I do not want to say much because there's experts with more experience. For my taste, the low-frequency range is too strongly emphasized that the enjoyment but greatly restricts in many musical genres. He's just a DJ headphones and suitable only mediocre for relaxed listening to music on the sofa. However, I hear with the headphones always things that are never noticed me in a song before.
