Petlor's EEx-approved Listen Only headsets are designed to ensure clear, reliable communication in extremely noisy environments, while providing
necessary hearing protection for the situation. The helmet mounted model is easy to install on most hardhats and helmets.
Soft, wide, foam and fluid-filled ear cushions and individually sprung headband wires of stainless sprung steel provide an even and consistent distribution of
pressure around the ears for the best possible comfort. Beam-mounted earphones provide the least possible resonance and distortion for excellent sound reproduction in even very high-noise environments.
