What this earbud does

The Califone E2 is a wired stereo earbud with a 3.5 mm plug and a 3.90 ft cable. It provides binaural sound for language learning, online testing and text-to-speech work on tablets, smartphones, netbooks, notebooks and desktop or laptop computers running iOS, Windows or Android.

Check your device before ordering

Verify that the host has a standard 3.5 mm mini-phone jack; devices that only offer USB-C or Lightning audio will need a separate adapter. The 3.90 ft cord length suits desktop use but may feel short if you sit far from the source. The package includes one pair of replaceable ear covers in medium and small sizes.

What the bundled items change

The supplied user manual explains basic operation and fit adjustment. Two sets of silicone ear covers let you swap between medium and small tips for a better seal and comfort during long sessions. No carrying case, inline controls or microphone are included.
