Wired PTT headset for Sonim XP Pro

The Rhino Klein Curl connects directly to the Sonim XP Pro handset through a wired link. Its push-to-talk button lets workers transmit instantly without touching the phone screen. The coiled cable stretches during movement and retracts to avoid snagging on equipment. Designed for frontline teams who need reliable voice communication in noisy environments.

Passive audio path with no battery

The headset draws all power from the handset, so there is no internal cell to charge or replace. Acoustic output depends entirely on the phone’s amplifier, keeping heat and electronic noise at zero. The lightweight frame adds no active cooling requirement and produces no audible hiss during standby or transmission.

Questions about this item

How do I plug the CURL-SO4-WP headset into my Sonim XP Pro?

Connect the headset's wired connector directly to the accessory port on the Sonim XP Pro handset; the push-to-talk button activates automatically once seated.

Which part of the CURL-SO4-WP headset will need replacing first?

The coiled cable and inline push-to-talk module endure the most flexing; replace them if audio cuts out or the PTT button sticks.
