Overall, the earphone does exactly what it should, it reduces unwanted background noise. The trick here is that you can be with active noise cancellation can still entertain fine. Above all, in the class of aircraft: the murmur of aviator fades into the background and the call will be clearer. Almost as if you can provide the engines for ACCOMPANYING THIS loud and quiet. With activated noise reduction, the music is amplified and clearly gaining brilliance, the bass and treble response will be improved and for the price range more than acceptable. The battery (1 x AA) holds loose 12 - by 15 hours.
As already criticized by others, the position of the electronics is not solved ideally. Somehow interfere 3.5 x 8 x 1.5 cm Box always or constantly falls down and then pulling the plugs. The only viable solution I've found is to put them in your shirt pocket - does not look great, but works fine.
The only real drawback is the interchangeable ear caps. From the idea is not bad, because they allow companies to a certain extent to adapt to the anatomic conditions the earphones. Unfortunately, it keeps the rubber only partially in place, which is why every time you have to be extremely careful that they do not fall off and stay somewhere. I had tuned it meant stick, but now it's too late, the last but one has somewhere adopted see between security, laptop bag and seat bag, never to return to the umpteenth flight. Now must be found, a new earphones and until then is it the noise on the plane stand bravely.
