Review on 🎧 Versatile Office Headset with RJ9 Jack for Cisco Phone & 3.5mm Connector – Ideal for Call Centers, Cell Phones, PC Laptops, Landline Deskphones by Kenneth Cotton

I was really blown away by this device. The microphone didn't work out of the box. It worked for 2 seconds, then was silent for 5 seconds, then worked for 2 seconds, etc. This thing is generally unusable. This defeats the purpose of it all. Of course I heard my customers perfectly, but they didn't hear me. I sent it back within 2 hours of delivery. This thing is terribly bad. And as another reviewer said, this is NOT a Cisco headset. How can they even call it that? Talk about false advertising.
