Even though my headset was unfortunately broken after a few months, I had lying after 2 weeks a new on the table. I am very well satisfied with the headset, since it allows me to perform both calls via landline, and via iPhone via the headset, so I'm as flexible as I have always wanted. In addition, it even has a function to record the conversation (this the interlocutor must be informed in advance of course). The headset battery holds a 8 hours lasting telephony was not. The headset is definitely suited for frequent callers, but call center staff I would not recommend it, since they would call it a day after 6 hours. I have also the Busylight to optional in use that my colleagues indicated, when I call straight.
