Klein Patriot Pro Wired PTT Headset for Sonim XP10, XP5plus, XP5s and XP8

The Klein PATRIOT PRO Wired PTT Headset is a professional 2-wire push-to-talk earpiece made by Klein Electronics and sold as an official Sonim accessory. Klein custom designed it to connect to Sonim's SecureAudio Connector on the XP10, XP5plus, XP5s and XP8 handsets. The rugged SO3 side connector screws into the handset, so the connection holds during active work. It is a full-duplex wired headset for users who need hands-free push-to-talk throughout a shift. The 2-wire design lets the cords run over or under clothing or a uniform, and a built-in clip holds the cable in place. A clear quick-disconnect acoustic coil tube carries audio from the balanced armature magnetic speaker to a replaceable earpiece for all-day comfort. The omni-directional noise-reduction microphone has -36dB±2dB sensitivity and a +58dB signal-to-noise ratio at 1kHz. Two front-facing PTT switches provide redundancy and are large enough to press in heavy work gloves. The PATRIOT PRO is built for demanding environments. Its Kevlar-reinforced cables are third-party lab tested to the IP67 rating standard, and it operates from -40°C to +80°C. Overall length is 78 inches, with a 26-inch top cable from the splitter and an 8-inch coiled bottom cable. The headset weighs 88g. It is designed and assembled in the USA and backed by a 3-year comprehensive warranty. A product datasheet is available.
