This headset has been the worst purchase I have ever made. Worked great for about a month. Then the microphone started cutting out to the point my job thought it was my system and they had to do a profile reset and set me back on my work for 2 weeks. Today the entire set DIED.

I bought the Jabra Pro 9450 Duo because I wanted a headset that would allow me to have long conference calls using the landline and Skype using the same headset. It's very good for that. It takes a little bit of setting up and I had to call Jabra tech support twice. They were very helpful.

Background noise is not cancelled out. If someone is talking say in another room and both doors are open, then the person you are talking to can hear the person in the other room. When i say hear, i mean the words not just a distance sound.

None - the unit was dead out of the box but not opened until past the 30 day return window

The unit was dead out of the box but we couldn't return it since it wasn't used until after the 30 day return window had expired; Won't be buying these types of devices on Newegg any longer

super merci
