I have been using this headset for 2 weeks now with my iphone and avaya x-one softphone. It integrates well with both. Audio & voice quality are excellent. The mute "button" while sometimes a little hard to pinpoint with your finger works great since it integrates with the phone.

its a great head set, however you have to but the adapter seperate and Staples does not carry it. With out the adapter you need to pick up the hand set on the phone even when using the head set

Been using these for a few weeks now and after the initial torture of trying to get the bleeding thing set-up we are now very happy with them. Phones themselves are very straightforward to set-up but struggled and struggled with the repeater.

Although I like the idea of this and was really excited to receive. Was disappointed when it arrived as the headphone jack was too small for any port on my laptop. This spec or lack of spec was not listed if you are looking for this item make sure you buy the one with the USB extension.

I've bought two of these before and liked them both so much, when we had a receptionist that needed a head piece, we bought her the same thing.

They are amazing! Comfortable, versatile and the sound is crystal clear.

The Jabra website states that this device is softphone compatible (and even has a picture of a laptop computer) but the jack that is meant to connect to the computer is not the right size. I love the Jabra products but was disappointed when I unboxed this item.
