Sensear SM1P2: The Industrial Headset for High-Noise Worksites

Who Sensear Is

Sensear is an Australian-founded company specialising in industrial-grade hearing protection and communication headsets, with products used across mining, oil and gas, heavy manufacturing, and aviation. Their core technology, which they call SENS (Speech Enhancement and Noise Suppression), uses directional microphones and real-time frequency filtering to do two things at once: block out harmful continuous noise while still letting the wearer hear nearby speech and warning signals clearly.

That combination, hearing protection plus situational awareness plus radio or Bluetooth connectivity, is what sets Sensear apart from a standard set of earmuffs.

The SM1P2 Series

The SM1P2 is Sensear's current flagship headset and its most popular model, available in behind-the-head and over-the-head configurations. Key features include:

• Hearing protection: rated up to 27 dB NRR (Noise Reduction Rating), suitable for genuinely high-noise environments.
• SENS technology: combines noise cancellation with natural face-to-face speech and situational awareness, so wearers are not cut off from their surroundings.
• Multiple connection options: Bluetooth for phone or music, direct two-way radio connection, and a short-range FM headset-to-headset mode, useful for small teams working near each other without a radio network.
• Battery life: a built-in rechargeable battery supporting long shifts, with a removable cable option for wired use.
• Configurations: available in headband, behind-the-neck, and helmet-mount styles to suit different PPE setups.

Other Models Available Through MSL

Mobile Systems Limited also stocks the SM1R, a radio-powered hearing protection headset that draws power from the connected radio rather than its own battery, making it lighter for extended wear. Alongside it, the SM1B is a battery-powered option with broader radio compatibility than the SM1R, better suited to teams needing longer, uninterrupted shifts.

Which model suits your team depends on your noise environment, whether you need intrinsic safety certification, and what radio and other PPE your crew is already using.

Why This Matters for New Zealand Worksites

Under the Health and Safety at Work Act 2015, employers have a duty to manage noise exposure risks. The problem with a lot of standard hearing protection is that it is so effective at blocking sound that it also blocks the verbal warnings and instructions that keep a site running safely. A headset that protects hearing without cutting workers off from their team solves a real, practical safety gap, not just a comfort one.
