If your cellular phone is not an iphone or android smartphone, it most likely has a single small round 2.5mm jack marked "headset." You should be able to use any of the corded M-series headsets below which have a 2.5mm headset connector.

For iPhone, Android, Blackberry and other smartphones, your device has a 3.5mm headset jack which requires a 3.5mm headset with 3 black bands on the plug (to make that extra stereo connection inside the port). You can use a 3.5mm headset, or choose any of the 2.5mm models and add the adapter shown at the bottom of this page.
