Poly CS540A DECT 1920-1930 MHz Headset TAA
$0.00
The CS540 convertible DECT™ headset provides professional performance so you can get more done — even on the move. The noise-canceling mic reduces background noise interruptions, ensuring great audio quality and easing listener fatigue.
Give everyone more freedom to move
Everyone in the office could use more flexibility. Let them roam confidently up to 400 ft from the headset base. They’ll be able to collaborate simply since teams can conference up to four headsets on a single base.
The choice is yours
There’s more than one way to make a call — switch up styles to find your groove and introduce your ears to something new. The CS540 convertible design comes with three wearing options: over-the-ear, over-the-head, behind-the-head[1].
Features
It’s just easy
Simplify desk phone management with headset audio controls and adding either the HL10 Handset Lifter or Electronic Hook Switch Cable (EHC) for remote call capabilities.[2,3]
Extended range and talk time
The adaptive power system optimizes for range and talk time by automatically downshifting to low power when the headset is close to the base — saving battery life and maintaining maximum density.
SoundGuard technology
SoundGuard acoustic limiting technology protects against Acoustic Shock by limiting sounds to below 118dBA ensuring listening comfort and protection against audio spikes.
Superior audio quality
Your choice of narrowband audio to extend talk time or advanced wideband audio for high — definition voice quality. Enhanced Digital Signal Processing (DSP) provides more natural sound, delivering clear audio the way it’s intended to be heard.
Maximum protection
The CS540 headset includes DECT™ technology that provides better audio quality and eliminates interference from Wi-Fi networks while calls stay safe and secure.[4]

I was tricked!
Sales lied to me and told me this would be a replacement for my Savi, but there's no USB dongle, despite the website saying there is! Absolutely ridiculous! Customer service is horrible!

Outstanding headset
I love this headset! I had one of these for many years and finally wore it out. So, I bought another one. I just love being able to walk around the house and carrying on telephone conversations hands-free. I have tried others and this is far and away the best.
I also think it is way overpriced. But, I like it enough that I am willing to pay the premium.

Where can I find the little white rubber band/grommet located on the ear piece stem? It's function is to create resistance between the unit and the over the HEAD headpiece. Its size is: inside diameter 1/8 inch, outside diameter 1/4 inch.
