Worked PERFECTLY with my phone at call center-was hard to hear customers with just one ear piece-definitely cut down on the background noise and makes it easy to hear customers-SUPER fast delivery-easy to use-VERY happy with this product and would recommend for any CSR!

Microphone does a good job of cancelling out background noise (screaming kids) and is clear to the caller on the other side

callers cam hear my radio in background they r supposed to cancel background noises

Totally blocks out background noise.

I love the productThe background noise cannot be heard, makes you feel like Noone is on the line.
