Good NoiseCancelling, impaired comfort

Application:
My employer is pulled in a loud office - right next to a main road and opposite the airport. Of course, after moving regularly somewhere Blazed craftsmen concentrate on their work with the windows open was not so. Even with headphones hummed the lorries through yet. So I was looking for headphones with noise canceling.

Noise Cancelling:
Well, I could with the windows open in the manner described, noisy environment work. This requirement has well fulfilled the headphones.
Meanwhile, I have the Bose QC 15 and since the noise-canceling is again much better, but the Bose is also more than twice as expensive.

Bluetooth:
With the Nexus 4, the headset immediately let coupling via NFC. Cable Free music enjoyment is a plus point for me. Unfortunately I could not connect via Bluetooth to your PC (Windows 7) the headphones. However, this is probably more of a Windows problem, but Sony can probably nothing. But I have the support at Sony contacted for this purpose and because it was said that Windows 7 is not supported just.
(In the first version of this review, I had the answer, unfortunately, not seen by the support in my spam folder and therefore deducted another point. This is now corrected.)

Audio:
Headphones to play music that does the Sony of course. He is a little bassy, ​​I have set the equalizer to neutral in return. For normal use, which is also perfectly adequate.

Comfort:
The Sony is designed as an on-ear headphones. In recent hearing that's fine too, but after an hour and more oppressed the earpads to the ear, so that I rubbed his aching ears after a working day. But that probably depends also from its own physiognomy, my not fit.

Conclusion:
A noise-canceling headphones without wires for about 125 euros - that's almost too good to be true. Here it is the comfort of the downer. I had the Sony one week return, because of the pressure by the ear pads was too uncomfortable. Who has right ear or headphones rearing the entire working day, for the Sony is quite a recommended noise-canceling headphones.
