The SM1P Series emerges as Sensear’s best-selling industrial headset

On a genuinely loud worksite, mining, oil and gas, heavy manufacturing, or an aviation apron, standard hearing protection creates its own problem. Muffs and plugs that block out machinery noise also block out the voice of the person standing right next to you, so workers end up shouting, pulling their protection off to hear each other, or missing safety calls entirely. Sensear was built specifically to solve that trade-off.

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 SM1P Series

The SM1P is Sensear's flagship headset and its most popular model. 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 aren't 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.
• Intrinsically safe versions: select SM1P models are certified for use in hazardous, potentially explosive atmospheres, for sites where that certification is a legal requirement.

Other Models in the Range

Sensear also produces 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. Also available are the smartMuff (an over-ear model with built-in FM and Bluetooth) and smartPlug (an in-ear, battery-powered option compatible with respirators and other close-fitting PPE).

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

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's 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.
