      Serenity SPC Ex hearing protection and ATEX communication

      Serenity SPC Ex is an intrinsically safe hearing protection headset, ATEX certified for operation with Motorola GP340-680Ex radios. It allows team members to communicate safely and clearly in noisy hazardous areas.

      Serenity SPC Ex features custom-made ear shells, a miniaturized headset and a PTT unit. Communications are heard in the ear while the surrounding sounds are strongly attenuated. The user’s voice is transmitted clearly through a noise-canceling microphone. And thanks to its lightweight and ergonomic design, Serenity SPC Ex’s wearing comfort is second to none.

    • eShells

      Phonak eShells

      ‘eShells’ are Phonak’s custom-molded in-ear shells. Offering the best hearing protection for full-time workers who operate in noisy environments, eShells are durable hollow molds made from clinical nylon.

      They are produced using a computerized 3D version of the user’s individual ear impression, which is taken beforehand by a hearing technician (a process that takes just 5 minutes).

      When a Serenity or Primero DPC+ system’s earJack is clicked into an eShell, the ear is instantly and fully sealed. Only sounds that have then been attenuated (reduced) by the user’s Phonak system reach the ear drum; protecting the user from dangerous noise throughout the day.

      • 100% individualized hearing protection
      • Perfect in-ear fit
      • Highly robust & machine washable 
      • Quick and cost-efficient reproduction
      • Easy to maintain and assess using SafetyMeter.
