3M WorkTunes Wireless Over-Ear Hearing Protector Connect & Solar with Bluetooth (model 90570E-1)

The 3M WorkTunes Wireless Over-Ear Hearing Protector Connect & Solar with Bluetooth (model 90570E-1) combines passive hearing protection with integrated Bluetooth audio to allow listening to music and taking calls while reducing ambient noise. The over-ear cups provide attenuation for noisy environments, and the headset incorporates solar-assisted power to extend battery life for extended use on outdoor job sites. Controls on the earcup allow volume adjustment and call handling without removing the hearing protection.

Advantages

This device provides simultaneous hearing protection and wireless audio playback, enabling users to maintain situational awareness while listening to media or handling phone calls. The over-ear design offers comfort for extended wear, and the Bluetooth connectivity supports hands-free operation. Solar-assisted charging helps extend operating time between manual recharges, reducing interruptions during outdoor work. Physical controls are positioned for easy access while wearing gloves or performing tasks.

Suitable for

• Outdoor construction, landscaping, and agricultural work where hearing protection and audio are needed
• Workshop and light industrial environments requiring moderate noise attenuation
• Maintenance, installation, or facility tasks with intermittent communication needs
• Users who need hands-free phone calls or audio guidance while working

When it may not be suitable

This product uses passive noise reduction and is intended for environments with moderate to high noise levels; it may not provide adequate protection in extremely high-noise industrial settings that require specialized, certified hearing protection with higher attenuation values. Also, Bluetooth audio can introduce awareness trade-offs—listening at high volume may reduce the ability to hear important signals or warnings in certain workplaces.

Key specifications

• Type: Over-ear passive hearing protector with integrated Bluetooth audio
• Connectivity: Wireless Bluetooth for audio streaming and phone calls
• Power: Rechargeable battery with solar-assisted power extension
• Controls: On-unit buttons for volume, playback, and call handling
• Design: Cushioned ear cups and adjustable headband for extended wear comfort

How to use

Place the headset over the ears and adjust the headband for a secure, comfortable fit ensuring the ear cushions fully seal around the ear to achieve effective noise reduction. Pair the headset with a Bluetooth-enabled device following the manufacturer's pairing procedure, then use on-ear controls to play audio, adjust volume, or answer calls. Keep the solar panel exposed to ambient light when possible to benefit from extended operating time between charges. Charge the internal battery as recommended by the manufacturer when solar assistance is insufficient.

What to consider before purchase

• Required level of hearing protection for your specific work environment; verify attenuation is adequate
• Compatibility with existing Bluetooth devices and preferred audio codecs
• Comfort for prolonged wear, especially if used with helmets or other PPE
• Battery life expectations and whether solar assistance meets your usage patterns

Usage recommendations

Use the headset at moderate volume levels to preserve situational awareness. Inspect ear cushions regularly for wear and maintain a proper seal for optimal protection. In environments with very high noise levels, combine with or choose certified hearing protection that meets required attenuation standards.
