unexpectedly strong noise

On the one hand you had the TV volume when using headphones to about "35" turn up (usually we watch TV in "12"). This leads partly to the fact that if you forget to turn in front off again Quietly, the next, the turning on the TV, a small (loud) experienced surprise.

On the other hand, I find the noise development but very strong. Only by aligning the transmitter back to the direction of the occupant and then holds the head in a certain posture, the noise disappears almost. Any small movement results in greater noise again.

All in all, for a device of the prestigious brand Phillips in my opinion, insufficient.
Have the unit therefore sent back, looking me now another, perhaps radio transmission ...
