## Customer Reviews

### ⭐⭐⭐⭐⭐ Works with Cisco 7942
*by A***R on August 18, 2020*

I bought the adapter so I could use a headset with my Cisco desk phone as I share an office space with three other people which can cause feedback on conference calls and make audio hard to hear due to the ambient noise. I am using a Turtle Beach Recon 50X headset and have had no issues with incoming audio nor outgoing mic audio. Definitely a big improvement over using speakerphone or holding the handset to my ear for up to an hour for conference calls. I'm not sure if the adapter will work with more elaborate headsets but a wired headset with noise cancelling may be my next purchase to further improve upon call quality.

### ⭐ Didn't work on Cisco 7942
*by M***T on March 23, 2021*

When using this the volume on my headset was so low it was almost inaudible. This was with the headset volume turned all the way up. I plugged it into the headset port and plugged my cell phone headset into it, then pressed the headset button on the phone (Cisco 7942), just as directed. The headset works fine with my cell phone so that's not the issue. I returned the cable.
