Dual protection is often a requirement in many critical working areas where exposures may exceed 95 decibels (dBA), Sensear has integrated our SENS communication capabilities for face-to-face communication and 360° situational awareness into an intrinsically safe dual hearing protection headset series (SM1P02 ExDP) so users can effectively communicate without removing their hearing protection in these extremely high noise conditions and hazardous environments.

! Cable connection to a Two-Way Radio available (sold separately)
! For Helmet Mounted headset style HELMET NOT INCLUDED

Based on the existing SM1P02-Ex headset, and incorporating our unique dual protection feature; the ExDP headsets fills the marketplace need for a high performance intrinsically safe headset for extreme noise environments that require ATEX and IECEx certifications. With customer focus and hazardous environments at the forefront of this robust headset design to enhance safety and communications for improved efficiency in high noise and hazardous workplace environments. The new cable connection at ear cup allows you to use it as a wired headset along with Bluetooth and Short Range or unplug the cable and use it as a completely wireless headset via Bluetooth and/or Short Range. It’s the perfect solution for your extreme high noise and hazardous environments such as explosive chemicals and fuels as well as combustible powders.

  • Compatible with industry leading  intrinsically safe two-way radios via removable wired connection or Bluetooth®

  • Connect to intrinsically safe mobile devices (HFP, HSP and A2DP profiles) via Bluetooth® for conversation and audio streaming

  • Up to 31 dB. NRR (noise reduction rating) / 39 dB SNR / 33 dB, Class 5 SLC80

  • Clear two way radio communication up to 120 dB noise levels with Noise-cancelling boom mic.

  • Ex: (UL/CSA/ATEX and IECEx) approved

  • Headset to Headset PTT communication (approx. 50m / 150ft range) via Short Range

  • Talk ‘face to face’ in high noise (No need to remove your headset or move to a quiet area)

  • SENS® Technology (Enhances speech while suppressing background noise to a safe level),

  • Programmable Volume Limiter (Limit ‘in-ear’ noise exposure to 82dB)

  • Retain 360° situational awareness (Remain aware of surrounding noises and hazards)
