I use this headset for four months now regularly along with a Siemens Gigaset C610A and am completely satisfied! + The headset is made solid and convenient to carry in my view even over longer duration (+45 min.). + The cable provides with 125 cm length sufficient scope and, if there should be times too long and in the way depending on the carrying method yet, be fixed by means of an adjustable clips eg on garments. + The headphone volume can be continuously adjusted using the rotary control rules (control on the cable attached), the audio quality is clean and does not bring further harm to the telephone signal with itself. According to my interlocutors also the built-in microphone headset does not reduce the audio quality. + The microphone is easily bendable in and swivel freely in the connection to the ear of the 08-clock position to 04-clock position, so you can wear the headset on both the left and on the right ear. + The angle plug is well crafted and ensures that the cable can be less easily damaged at the connector. + The headset can be quickly and compactly folded.
I would recommend because only fully this headset considering my purely positive impressions and the relatively small price!
