Frequently bought together:


  • Convert two 3.5mm plugs to single 4P4C RJ9/RJ10 Cisco headset plug
  • Works great with Cisco VOIP office phones with a RJ9 headset jack
  • Save money by buying PC headsets to use with your office phone's headset jack
  • Reduce clutter with single headset
  • Does not work with RJ11 jack, which is wider than your headset jack (6 positions vs. 4). RJ11 jack is what is in the wall. RJ9, RJ10, RJ22 are what is on your phone handset or headset.
  • Works with mono and stereo PC headsets!
Why buy an expensive headset just for your office phone? Use the Headset Buddy Adapter and your existing computer headset with most Cisco VOIP office phones that have a headset jack.

A money saver for home businesses, call centers, sales people, or anyone who is on the phone all the time, and wants to use a lower cost or more comfortable PC headset. 

This amazing adaptor converts the standard headset 3.5mm mic/audio plugs to a standard RJ9, RJ10, or RJ22 handset plug, allowing you to use your favorite computer/laptop headset with your Cisco IP phone. This adapter is designed for use with headsets that have two 3.5 mm. plugs; one for the microphone and one for the headphones/earpiece(s). The adapter outputs binaural sound for stereo headsets, meaning you will hear sound out of both ears. The adapter cable is approximately five inches long.

    Makes working in a call center bearable

    Posted by PR0XIDIAN on 26th Jun 2012

    I don't care if I'm getting yelled at, or if a customer is so mad that they are cussing me out. Why? Because my headset is comfortable! (Unlike my co-workers). I highly reccomend you pair this with a pair of plantronics gamescon headset. http://www.amazon.com/dp/B006ZS5AQA/ref=asc_df_B006ZS5AQA2071054?smid=ATVPDKIKX0DER&tag=hyprod-20&linkCode=asn&creative=395093&creativeASIN=B006ZS5AQA&hvpos=1o2&hvexid=&hvnetw=g&hvrand=125340401709989063&hvpone=&hvptwo=&hvqmt=

    It works GREAT! Very comfortable and fits my call center's phones! :D
