Review on RJ9 Telephone Headset Dual W/ Noise Cancelling Mic For Yealink, Avaya, Grandstream & More - Quick Disconnect (602QY1) by Atheendra Wroblewski

I work in a call center. I bought this to use with my avatar phone. I checked the avaya phone model to pick the right headset. After using for 2 weeks, I like the ability to head out of both ears. It is not too tight. But today I noticed the calls are scratchy. So I picked the handset and no scratchiness to the calls. Very disappointed in sound quality. I will likely return. Hoping it is just a bad headset.
