I wont bother with the technical specification of this headset as I will probably get it wrong and can easily be found on a different page.
Throughout my working life it has revolved around headsets one way and another and I think I have a pretty good understanding of them. I have to say to date this is the best headset I have used.
My only disadvantage is that it seemed more complicated to set up than it should have been (this may be down to human error!!).
Once the headset was set up, it is easy as pie to use and the clarity of the speaker is better than the normal handset on my land line. Also from feedback from the people I speak to they say that everything is clear from their end and that is hardly any background noise and I work in a fairly loud office.
I use the headset for long conference calls so that I am able to use my laptop to the full potential to make notes and send out documents mid conversation. There are times where I am on conference calls in excess of 2 hours and the headset is very comfortable to wear.
Also there have been times on a call where I need a drink and the kitchen area of my office is at the other end of the office and the headset deals with the range without any interference or crackling you can find on some cheaper headsets.
This headset is quite expensive but I feel it is money well spent as it is comfortable and durable. I think it is ideal for anyone who spends a long amount of time on the phone.
