Language OK, plug well

If a headset with mid-priced you can not expect top quality in terms of noise. Had I myself do not. And the first experiments showed: The acoustics are the listening and speaking skills (how my interlocutor understands me) while audible worse than directly to the phone, but in no way restrictive or bad. She is good! I'd give four points even for the value for money in terms of noise.

Why but just three points total? The plug bothers me a bit:
I run the headset to a Siemens Gigaset (a C385; but probably the following applies to all Siemens Gigaset). The jack is the case - something sunk - for some unknown reason to me. The sinking is not circular but rather half-rice-shaped.
The plug of the headset in turn is angled (which is OK), but unfortunately a bit thick. He still fits so precisely into the socket. Unfortunately, the plug is also not circular - also not understandable. During a telephone conversation, it is me often happens that the cable of the headset by its weight to plug something has rotated about its axis. And what happens when two non-circular connecting elements which fit in only one position so now? That's right, the plug is pushed a little bit out of the socket - and in this case has no more contact. Conclusion: I have practically always hold the housing of the connector. Is not a serious problem, but a bit annoying.

I will therefore itself tinker me a plug adapter piece with narrow bezels. Then the problem should be settled and I can undisturbed and relaxed phone calls.
