Klein Patriot Pro Wired PTT Headset for Sonim XP Pro (SO4)

The Klein Patriot Pro Wired PTT Headset (Klein SKU PATRIOT-PRO-SO4) is a 2-wire surveillance-style earpiece built for the Sonim XP Pro. Klein Electronics makes it, and Sonim sells it as an official accessory. It is designed for security teams, event staff, public-safety and field crews who run push-to-talk on the XP Pro and need discreet, hands-free audio all day. Audio comes from a balanced armature magnetic speaker and travels through a clear acoustic tube to the earpiece. The tube disconnects quickly and can be replaced, so you can swap in a fresh tube or earpiece for hygiene or comfort without replacing the whole kit. A professional noise-reduction microphone handles transmit audio. The dual front push-to-talk button is large enough to operate with gloves on. The 2-wire design lets you route the cables over or under clothing for a clean, low-profile setup. The cables are Kevlar-reinforced to resist wear. The headset attaches to the XP Pro through a rugged secure audio side connector that screws into the handset, so it stays connected during movement. Klein backs the Patriot Pro with a 3-year warranty.
