Klein Patriot Pro Wired PTT Headset for Sonim XP Pro

The Klein Patriot Pro wired PTT headset in its SO4 version is built for the Sonim XP Pro, connecting through that phone's accessory interface to deliver headset-grade push-to-talk audio. It is the option to specify when users do not just answer occasional calls but work the channel continuously — dispatch-heavy field service, yard operations, security details, and transit crews. Compared with a slim earpiece, the Patriot Pro's headset-style design gives users more substantial receive audio and a consistent microphone position, which keeps transmissions intelligible in loud environments. The design wears stably across a full shift, an underrated factor in whether communications gear actually stays on users' heads or ends up dangling around their necks. The wired PTT control keys the XP Pro's push-to-talk service with a single press. Everything runs through the wired connection, so the accessory needs no pairing, charging, or battery tracking — the phone is the only device IT manages. For fleets standardizing on the XP Pro as a rugged PTT-over-cellular handset, that operational simplicity scales cleanly from ten users to a thousand. The PATRIOTP-SO4-WP carries UPC 198715306668 with a listed shipping weight of 1.75 lb, distributed by Social Mobile. Fleets still running XP5s, XP8, XP5plus, or XP10 hardware should order the PATRIOTP-SO3-WP for those connectors.
