Heavy-Duty Behind-the-Head Headset with 24 dB Noise Reduction

The Motorola PMLN8085A is a heavy-duty, dual-ear headset engineered for clear two-way radio communication and hearing protection in high-noise work environments. Its behind-the-head design leaves the top of the head unobstructed, making it suitable for use with many hard hats, helmets, and other head-worn protective equipment.

Dual speakers deliver radio audio to both ears, while the flexible noise-canceling boom microphone helps provide clear voice transmission by reducing surrounding background noise. A large push-to-talk button on the ear cup remains easily accessible while wearing work gloves.

With a 24 dB Noise Reduction Rating and UL TIA-4950 intrinsic-safety approval, the PMLN8085A is designed for demanding industrial, public-safety, and hazardous-location operations when paired with an appropriately approved Motorola radio.
