Stereo headphones should be used with all of our radios; they use the standard 3.5mm (1/8 inch) connector. If you are using headphones with the Model One radio you should use stereo headphones, as a monaural ear piece will not work.

You can check if your headphones are stereo by the number of blue rings around the tip; two rings indicates stereo. Headphones rated at 32 ohms will work best with our radios.
