Great sound, which you can not enjoy a very long time.

That reminds me mitlerweilse the earpieces of the AKG K 272 HD occur too small, and I wanted to have an open headphones, the AKG Q701 for the price (about 250) was a good choice. The sound of the headphones is great, but I suppressed the headband for something two hours so much that it's painful. This is due to the rib-like structure of the tape. By comparison, the AKG K 272 HD has a Klatte band, and I can have it almost indefinitely on.

Pro:
- Great sound
- By large open design Klangraum
- Replaceable cable, there are 2 delivered
- Mini XLR connector for cable
- The cables are quite soft, so the coiled shape in the reserve not long they are supplied
- I like the green color of the headphones good

Con:
- Comfort, the headband presses quickly

Although the sound is great, I can unfortunately only awarded 3 stars. The best sound is useless if you can not hear him because the headset is uncomfortable.

UPDATE:
I was at the hairdresser. This in itself is not bad, but because my hair is much shorter now (about 1 cm long) is doing my head after a few minutes of the headband hurt. Result: the headset has been sent back.
