Review on 4P4C RJ9/RJ10 to 3.5mm Female Headset Adapter Cable for Cisco IP Phones - Enhance Audio Connectivity and Experience by Jerry Estrada

Revainrating 4 out of 5

Works with Cisco CP-8841

Using the "#1" adapter cord works well with the Cisco CP-8841 desk phone. Each pigtail adapter had a loud whistle and on #2 and #3 I didn't even have a sound in one direction. With pigtail #1 it seemed to work fine with good call quality. It looks a bit hackish but gets the job done for a reasonable price.

Pros
  • Good Value
Cons
  • Not sure
