Review on 📞 Upgrade Your Call Center Efficiency with the VOISTEK Corded Call Center Telephone Headset RJ9 Headphone with Mic Noise Cancelling (Binaural K20) by Jay Huang

Fast delivery. Came in a plain box with no instructions or other documentation. I use it with my AT&T CL2909 phone and have had it for a few weeks now. Lightweight, seems cheap but decently made. The headband adjusts quite well, although I do find it a bit uncomfortable after about an hour. The sound quality is mediocre - basically no high frequencies, the sound is a bit muffled. Overall I'd say quite serviceable, comfortable enough if you need a headset with an RJ9 connector, but nothing special.
