How to choose the right cord for your wired headset?

Most corded headsets require a cord to connect to your telephone or computer. To connect to your computer, this is pretty straight forward, you either select a direct connect USB headset or select the connecting cord with the USB option. If you are using a soft phone only and the headset is only to connect to your computer, a direct-connect USB headset will be the most cost effective option. Most people are familiar with what a USB looks like, but for those of you who don’t, a USB connection looks like this.

On the other hand, a telephone headset will have a Quick Disconnect plug that needs another cord to connect to the telephone. Different headset brands have different Quick Disconnect fittings, which require their own branded telephone connection cords. This is an example of a Quick Disconnect plug.

Take a look at the side or bottom of your telephone to work out what type of connection cord you need to connect your headset. Most modern telephones will have a picture of a headset near the headset port. The different types of headset ports and connection cords are explained below. (All the pictures are of the cords which fit into the different headset ports)

RJ Connection Cord: The RJ connection cord plugs into a port which is a rectangular hole, with a smaller rectangle on the bottom. It is similar to the one the curly handset cord plugs into on your telephone. If your headset port is rectangular it is most likely that you will need the RJ connection.

2.5 mm Connection Cord: The 2.5mm connection cord plugs into the headset port which is a circular hole. The headset port will have an internal diameter of 2.5mm. The cord has the male pin, which is also 2.5mm in diameter to fit the port.

3.5 mm Connection Cord: The 3.5mm connection cord plugs into the headset port which is a circular hole, just wider than the 2.5mm. The headset port will have a 3.5mm internal diameter and the male pin of the connection cord is the same as the 2.5mm, just fatter.

There are a couple of other options such as amplifiers and switch boxes. Some telephones with low amplification or those that don’t have headset ports may need an amplifier. A switch box can also be used if your telephone doesn’t have a headset port. Contact us if you have any questions at:
