Ordered this to use with Plantronics headset. It didn't work. I borrowed the Plantronics adapter from someone to use in the meantime.

This product was everything it was promised to be on the web and has worked perfectly for us with Plantronic headsets. Also, the delivery was organized, quick and painless. We will certainly order again if we ever have the need!

Didn’t work.
