Phone Headsets, Handset Cords, Batteries and Mounts

Which port does your phone really have?

A headset must plug into something the phone offers. Desk phones often have a dedicated headset jack in the RJ9 style, which is not the same as a USB port or a 3.5 mm audio socket. USB headsets suit computers and softphones, 3.5 mm plugs suit mobile devices, and wireless headsets add a base or dongle. Single-sided headsets leave one ear free for the room, double-sided ones block more noise. If the phone has no matching port, look for an adapter cable made for that phone and headset pair.

Cords, cushions, batteries and brackets fit one model

Most accessories here fit a single model or family. A coiled handset cord links the handset to the phone body and uses a smaller plug than the line cord that runs to the wall, so do not mix them up; length is listed for the stretched cord. Ear cushions, batteries and cases are named for a headset or handset series, and wall brackets and VESA mounts match a specific device. Copy the model number from the label on your device and compare it with the listing title.

Questions about Phone Headsets, Handset Cords, Batteries and Mounts

What is the difference between a handset cord and a line cord?

A handset cord is the coiled cable between the handset and the phone body. A line cord is the flat cable from the phone to the wall jack. Their plugs differ in width, so check which one the listing describes.

Can I use any headset with my desk phone?

Only if the connector matches. Check the phone's headset port type and whether it supports an electronic hook switch for answering from the headset. Without a matching port, a USB or Bluetooth headset needs an adapter or a base designed for your phone.

How do I choose a replacement battery for a cordless handset?

Match the chemistry, voltage, capacity and connector printed on the old pack, or use the model number given by the handset maker. A pack that fits physically but has the wrong voltage or polarity can damage the handset.
