Who often calls with a standard telephone will know that the horn is very awkward. It always uses one hand at least or must be pressed to the shoulder with a jaw, which causes neck injuries. KÖNIG has a very payable and usefull solution; a headset with telephone connection.
The RJ9 plug only has to be placed in the telephone and the headset is ready for usage. The headset is equipped with a sensitive and clear microphone with noise reduction and is very comfortable to wear.
