Corded Telephone Headset Mono Universal Compatible with All Landline Desk Phones, Xintronics RJ9 Headsets with Answer Button, Noise Cancelling Mic, Volume Mute Controls(XT402) (Binaural-XT402)

Works great- plugged directly into the phone. The direct connection box arrived without good instructions. Actually pretty good value for an inexpensive item.

The headset will only work as a replacement for the handset. NONE of the various headset control features work. I decided to send the unit back. The company agreed to take it, but I had to MAIL IT BACK TO CHINA. Cost to mail it back is $27.00. I will not do any more business with the company because they do not pay for the return.

I couldn't figure out how to connect to my phone so i cant say if it works or not

Sound was terrible and wouldn’t sit well on my head. And when talking it sounds like a tunnel. Very cheaply made. I need this for work at home and on the phone 8 hours a day this is a lousy product to use.
