Iridium Wired Headset

The Iridium headset provides both an earphone and a microphone in one compact unit for simple, hands-free, and private conversations. It connects directly to the headset port on the right side of your phone and allows you to make or receive calls while keeping the handset upright for the best satellite signal.

Tip: Keep the accessory cover closed whenever the headset is not in use to protect the connector from dust and moisture.
