Sonim Klein CURL Wired PTT Headset (CURL-SO4-WP) for Sonim XP Pro

The Klein CURL Wired PTT Headset is a push-to-talk and full-duplex wired headset built for teams equipped with the Sonim XP Pro. Klein Electronics custom designed it to connect to the XP Pro's SecureAudio Connector. The headset connector screws into the handset, keeping the audio link secure during active work. Comfort and hygiene come from the over-ear design. A flexible C-ring earloop holds the headset in place while the speaker rests on the ear. The speaker swivels for right- or left-ear use, so one model suits every worker. The large, easy-to-access PTT button is tactile and compatible with heavy work gloves. A built-in swivel clothing clip keeps the 46-inch Kevlar-reinforced cable secured to a uniform. The in-line, omni-directional, noise-reduction microphone covers 50 Hz to 10 kHz with a signal-to-noise ratio of more than 58 dB. The 16 Ω speaker is rated at 500 mW, with 800 mW maximum input and 105 dB sensitivity. The CURL is designed and assembled in the USA and weighs 39 g. It is third-party lab tested to the IP-67 rating standard (Pony Lab certified) and operates from -40°C to +80°C. It carries a 3-year comprehensive warranty, which suits XP Pro deployments where equipment is expected to last through demanding shifts.
