Sonim Technologies launched Klein waterproof headsets and RSMs, compatible with Sonim SecureAudio Connector handsets, including XP3, XP5s and XP8. Over the past year, Sonim and Klein made it their mission to overcome top customer objections related to rugged audio accessories – affordability, waterproof and warranty. The companies now offer the most affordable, waterproof headsets and RSMs with an industry leading 3 year comprehensive warranty via leading mobile operators and distributors across the globe. Key products available and compatible with Sonim's handsets include: Klein VALOR RSM meets IP-66 performance standards and includes two large PTT buttons (front-facing and thumb) and overmolded rubber for grip. It also has a locking earpiece port for a listen-only earpiece, which redirects the receive audio from the speaker to reduce ambient noise levels and potential sensitive information. Klein VALOR RSM with 16-channel and volume selectors meets IP-66 performance standards and includes two physical knobs for channel and volume selection, two large PTT buttons (front-facing and thumb) and overmolded rubber for grip. Klein CURL headset rests on either ear for comfortable, all-day use, and has an all new design for tactical grip with an IP-67 waterproof PTT button. The PATIOT-PRO headset is a 2-Wire design allowing the headset cords to be clipped over or under clothes or a uniform, while on the job, and meets IP-67 performance standards.
