Ear Muffs 3M Pro-Protect 90545E with Bluetooth and Active Microphone, black/red

3M Pro-Protect 90545E ear muffs are over-ear hearing protectors combining passive noise reduction with Bluetooth wireless connectivity and an active microphone for voice transmission. Designed for use in industrial and outdoor environments, these ear muffs allow users to receive audio and make hands-free calls while maintaining protection from hazardous noise levels. The cups are finished in black and red and engineered for continuous wear during shifts where communication and hearing protection are both required.

Advantages

The integrated Bluetooth module enables wireless audio streaming and phone call handling without removing the ear muffs, while the active microphone supports clear voice transmission in noisy settings. The ear cups deliver passive attenuation to reduce ambient noise, and the cushioned headband and ear seals are designed to improve comfort during extended use. Controls for pairing and call management are built into the unit for on-device operation.

Suitable for

• Construction sites and building works where hearing protection and communication are required
• Workshops and manufacturing floors with medium to high noise levels
• Outdoor maintenance, landscaping, and groundskeeping tasks involving equipment noise
• Logistics and warehouse operations requiring hands-free calls and radio use

When it may not be suitable

These ear muffs provide hearing protection and wireless communication but are not certified hearing protection for all regulatory limits—verify the attenuation ratings for your specific workplace standards. They are intended for environments where Bluetooth connectivity and an active microphone are useful; they may not be necessary in settings with low noise or where wired communication systems are required.
