“CD” stands for “Controller and Dispatch” applications. It applied to a number of products that Poly (formerly Plantronics) makes.
The existing portfolio of CD Headsets that we offer are:
H31CD: Single over-the-ear headset, ear tip receiver with a voice tube microphone

- $123.58 Poly TriStar H81N-CD Headset | Poly 40203-14 or HP 8K781AA#AC3(Quick Disconnect)Add to cart
Because CD headsets are used on radio equipment, the entire portfolio is traditional “narrow-band” receiver audio.
