This is by far the best all!
The cable is sufficiently long and not too long.
It fits comfortably and you still have to take an ear Umgebungsgräusche free true.
The voice quality while facing should have no difference to the normal call. People realized not even know that I had in between plugged the headset. :-)
The sound quality of the speaker is absolutely sufficient and ok (a sound - Quiet regulator is in addition to the cable).
To date, no torn hair!
Use the headset to my Panasonic KX-TG8220G phone with the Panasonic KX-TCA828EXB belt clip Cordless Phone black
Pay attention that buys you the right belt clip for your phone. This headset should work on all phones.
