The headphones feel valent, the design is simple and not too bulky. The earcups sit on the ear and isolate accordingly not perfect. While jogging one hears the way no Bügelknartschen like me had very disturbed at the Philips O'Neill.
Quality defects: the old model broke through with me and was replaced accommodating and free. The microphone cable (with 90cm too long for my taste) is not that great. The plastic of the new cable (new TMA-1 model) is very hard and retains the shape gezwirbelte the delivery status. The first model, the Micro, incidentally, was broken in a little downpour, but the headphones remained intact.
Seat: my headphones are something crunchy fitting personally. For prolonged wearing uncomfortable with glasses, but also have a broad head - hat size XL.
Conclusion: among people with small / normal sized head and non-eyeglass wearers the best headphones I know. The thread for the interchangeable cable is also great - no accidental slip out more. And the service of AIAIAI is unsurpassable. If damage is found a solution accommodating.
