Simple yet rock solid


Rock solid headset system! I've tested many different headset systems and the S11 just works. Used them with Cisco, 3Com, and Avaya phones in three companies so far

Cord connecting to the system to the phone could be about a foot longer. Hate having to buy extra cords to make it easier for us to use the S11s

I've only had this model for a short period of time I was trying to stick with the older m-10 models because the wiring is more insulated than that of the newer models which helps to isolate interference from all the electronics that I work around. I...

Plantronics S11 Headset


Great headset for the price!! I thought it would take a week to 10 days to get it and it came within 2 days which was great. I have had clients tell me that you can't even tell that I am on a headset and the noise canceling microphone is great and...
