Sonim Introduces Waterproof Headsets and RSMs with 3 Year Comprehensive Warranty from Klein Electronics

Austin, Texas (Sept. 9, 2021) — Sonim Technologies (Nasdaq: SONM) 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.

“Device failure is a major issue impacting enterprise operations and increasing overall total cost of ownership,” said John Graff, CMO, Sonim Technologies. “Our 3-year warranty demonstrates we stand behind our rugged performance standards, instilling confidence in first responders and industrial workers who rely on the Sonim and Klein combined solution for critical communications in their operations.”

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.
