Note that the Blackwire 500 series has 4 variants: C510, C510-M, C520, C520-M
C510 is monaural (has only 1 earpiece to which the microphone boom is attached). C520 is stereo. Both are built for UC applications and softphones from Avaya, Cisco, and more.
C510-M is monaural (has only 1 earpiece to which the microphone boom is attached). C520-M is stereo. Both are certified for Microsft Skype for Business and Optimized for Microsoft Lync.
If any doubts, Plantronics has a helpful site and my calls to their sales team have always been met with cheerful and helpful advice.
This unit also works well with Skype, seamless integration.
I've now had this headset for about a month, and really like it. Lync instantly recognized it upon plugging it in, and all of my callers have commented that I sound great. And it's comfortable sitting on my head hours at a time.
I would say the main negative for me is that the microphone arm tends to want to hug my cheek/lips...so i have to re-adjust it a fair amount mid-call so that I don't have any heavy-breathing into my mic.
Other than that...it has been great!
