## Long description

The 3M Peltor WS Alert X MRX21P3E3WS7 is a Bluetooth headset designed for attachment to safety helmets, combining active wireless communication with passive hearing protection. This model is supplied with P3 particulate filters and provides an SNR of 30 dB to reduce harmful noise levels. The headset integrates audio streaming and hands-free communication functions while mounting directly to compatible safety helmets, intended for use where both hearing protection and voice communication are required.
Advantages
The headset delivers a balanced combination of hearing protection and wireless connectivity, allowing users to receive audio and make calls without removing protective headgear. Supplied P3 filters offer a high level of particulate filtration while the SNR 30 dB rating provides measurable attenuation of surrounding noise. The helmet attachment design keeps the earcups secure and aligned for consistent protection during work activities.
Suitable for
Construction sites where helmet-mounted hearing protection and communication are needed
Industrial environments with high ambient noise and a need for hands-free calls
Outdoor maintenance, utilities, and forestry operations requiring particulate filtration and noise reduction
Teams that use Bluetooth audio for instructions, alerts, or media while wearing safety helmets
When it may not be suitable
This headset is intended for use with compatible safety helmets; it may not fit non-compatible headgear or be practical for hard hats without the required attachment points. It is designed primarily for protection against particulate matter and noise reduction — it is not a substitute for respiratory protection against gases or chemical vapors. For noise environments exceeding the device’s rated attenuation, additional hearing protection strategies may be necessary.
Key specifications
Protection rating (SNR): 30 dB
Filter type: P3 particulate filters (included)
Mounting: helmet attachment for direct mounting to compatible safety helmets
Connectivity: Bluetooth wireless audio and communication support
Colour: yellow
How to use
Attach the headset to a compatible safety helmet following the helmet manufacturer’s and headset mounting instructions to ensure a secure fit. Fit the earcups over the ears so the seal around the ear is even and comfortable. Pair the headset with a Bluetooth-enabled device according to the included pairing procedure to enable audio streaming and hands-free communication. Replace P3 filters as recommended by the filter manufacturer or when breathing resistance increases; inspect the headset and sealing surfaces regularly for wear or damage.
What to consider before purchase
Confirm compatibility with your specific helmet model and attachment points
Verify that SNR 30 dB provides sufficient attenuation for your typical noise levels
Consider whether particulate P3 filtration meets your respiratory protection needs or if additional respiratory PPE is required
Check Bluetooth compatibility with your communication devices and any required audio profiles
Usage recommendations
Use the headset as part of a comprehensive hearing and safety program: ensure correct helmet and headset fit, regularly inspect filters and seals, and follow workplace guidelines for PPE. For optimal performance, keep firmware and paired device settings up to date and replace filters according to usage and contaminant exposure.
