2.5mm Telephone Headset Jacks, dont be square!

Some modern business telephones now have 2.5mm Telephone Headset Jacks. This would be considered quite normal for a cordless DECT phone (like you have in the home) but a handful of manufacturers are now producing commercial business desk top phones with a 2.5mm round pin headset port .

Until recently, headset connection has always been the standard RJ11 square pin jack and this made things a lot  easier when sourcing the correct headset for your phone. It appears that some brands, for example, Cisco have inherited this 2.5 mm non standard headset jack with the re-branded Cisco SPA handsets originally from Linksys.

Other telephone brands like the Panasonic DT series IP phones, Grandstream and the BT Converse 2025 also require a 2.5mm headset bottom cable to enable connection.

It is worth noting that not all the phones in the above series require 2.5mm headset cables and whilst we don't know why that is, one thing is for sure, standardising headset ports with the same connection method would make the task of choosing a telephone headset far simpler. oh and one other thing, "Quality" is the name of the game here, some cheaper headsets do lack in call clarity, especially used on IP handsets, you do get what you paid for in the headset game.

Headsets for Business stock headsets with 2.5mm bottom cables and a selection of professional headsets that are compatible with the brands and models mentioned above.

Prices start at £59 for the Streamline ProV 2.5mm , we also recommend the ProVX 2.5mm telephone headset its worth the extra £10 mainly due to the call quality and the repuatation they have for working 1st time, every time!

Below is a list of individual models that require 2.5mm Telephone Headset Jacks to work.

  • Panasonic DT 321 / 333 / 343 / 346
  • Panasonic 7630 / 7636 / 7633 / 7668 / 7730
