Sonically I to the headphones faulted. It emphasizes the bass and treble but also provides for a neat idea. The headphones are also many other louder than the original iPhone-run speakers. Noicecancelling I could not really notice, but I had not the right environment. The microphones work, the tonal quality I can not say anything, but my interlocutor has understood me.
The fit of the ear cushions (M) and headphone size are Ok. The remote is big enough and loud / quiet can be good distinction towards the middle button.
But what does not fit *** ***, the suitability for runners. The remote control is clearly difficult at the thin cable to near mounted on headphones while running and thus shaking the remote control in front of the face uncomfortable back and forth. This also means that the headset becomes loose while running continuously in the left ear (where the remote control is attached).
This is still tolerable and with corresponding fixing to avoid almost, but the remote control seems to be a real breaking point. I ordered the first headphone and after 3 weeks he was gone, the left ear had no power and brought only thin faint sound. I have the headphones then exchanged without charge for replacement of Amazon, for the same model. This time came the same problem after 5 weeks.
Amazon has withdrawn the second headphones again, and I ordered a different model of Sony. Let's see how this cuts.
The model Sennheiser MM 30i is not suitable for me.
