Review on RJ9 Telephone Headset for Call Centers on Landlines with Noise Cancelling Mic | Compatible with Yealink, Grandstream, Snom, Panasonic | Includes Additional 3.5mm Connector for Mobile Devices by Joshua Gulledge

The sound quality of this headset is good. Not great but good. The microphone works well too. There aren't many of them, in fact there aren't any extra features in this headset. The microphone can be rotated so you can position the microphone on either side of your face. I think it's a feature. There are many different connectors for phones in the box. And it comes with a standard audio jack plug, which is why I got it. But there was no USB port. Which is very bad. I don't currently need a USB port, but it would be nice to have one just in case. There is no volume control and no option to mute the microphone. The worst part is the headband. It's a thin band that digs into my scalp. When I wear a hat it's ok, but it's very uncomfortable on my head. So for the money, this headset is clearly overpriced. Actually it shouldn't be more than 20 dollars. I do not recommend this headset to anyone.
