Perfect down to reception disturbances

The headphones I like very, very good match, and even with a lot of movement they hold.
Sound quality is also good and easy to use is easy even when cycling.
However, there is disruption, interference and abrüche when the phone more al 0.5 - 1m away when sitting quietly with cell phone in your pocket is almost flawless.
Cycling with mobile phone in the pocket bike (no more than 1.5 meters, rather 1m) headphones are completely useless, constantly there are interruptions, so every 3-6 seconds, sometimes for 1-2 seconds, when it in your pocket doing it is a little better but also far from acceptable.
