Find your phone brand and model

Look at the label on the bottom or back of your phone. The model number helps confirm the right connection type.

Frequently asked questions

Quick answers for choosing and setting up a desk phone headset.

Most office desk phones use an RJ9-style wired headset connection, but the right choice depends on your phone brand, model, and port layout. Start with your phone model number, then match it to the RJ9 or 2.5 mm collection.

These names are often used loosely in headset shopping. Many desk phone headsets use a small modular plug commonly called RJ9, RJ10, RJ22, or handset-style connector. Always confirm the phone port and product compatibility before ordering.

Choose mono if you need to hear coworkers or the surrounding environment. Choose dual-ear if you handle long calls, work in a noisy office, or need stronger focus during customer conversations.

USB headsets are usually best for computers, laptops, and softphone apps. Some modern desk phones may support USB audio, but many traditional office phones require RJ9 or another phone-specific connector.

First confirm the headset is plugged into the correct port. Then check the phone headset setting, microphone mute state, cable connection, and mic position. If your phone has multiple headset modes, test the available options.
