Comment: My company bought everyone this phone. From my experience it works great. Clear sound for incoming and outgoing and comfortable (for me at least). Our office upgraded our phones to wireless. We now use PLANTRONICS CS50. Plantronics also have good customer service. The replace any problem with their merchandise within the year of purchase. Great investment for all.

Summary: Does the job but...
Comment: I have this at work. It does the job okay, but people sometimes have a hard time hearing what I say, even though I have the speaking volume turned all the way up. The other drawback is that you can't switch out headsets with it - you only can use the monoaural headset that comes with it, which isn't so good for noisy environments.Other than that, I have been using it for over 6 months now and it has been working well enough to keep.

Summary: Works perfectly for me
Comment: I first wanted to respond to a concern about terrible screeching when used in office multi-phone conditions. I can't speak to multiple S10's in the same office but did have a screech on first try to another extension. The amplifier, however, has 7 configuration settings. I found several settings worked for outgoing calls but only two worked for both in office and outgoing use. So if a second headset is bought in my office I'll respond to whether we could find a configuration setting for both headsets that worked. I supposed that just confuses the concern.The earhook setup is light and I find that I forget I'm wearing it until I run into the cord turning my chair or standing up. It is nice that nothing actually sits inside my ear but rather it rests gently on the outside.
Volume wise: In addition to adjusting the volume and tone of incoming signal it really has power available to broadcast your voice out. There are two ranges available for output as well as a volume in each range. The highest range is too much but it is good to know its there if I ever get someone complaining they can barely hear me (as happened all the time with a previous headset system).
