Have been using a ZMS 10C for years with some complaints about VOiP voice quality. Also use Dragon Naturally Speaking and thought I was getting good quality. But changing to ZMS 20 opened my eyes to the problems I could not explain using the ZMS 10. Phone call quality has improved dramatically with no complaints about echoing or being static on the line. The quality of my writing with DNS also improved a great deal with DNS better writing what I am saying. I did purchased a new Onvian 3.5 headphone jack to use with the ZMS 20 so in combination they have vastly improved my work life.

It's working well, but the setup instructions for my application could have been clearer. However with a little trial and error I've managed to make it do exactly what I hopped it would.
