Product Features
3-Level Hearing Protection
The H23 headphones come with three interchangeable ear tip sets (tri-flange, foam, and round tips in S/M/L sizes) to provide customized noise reduction from 20dB to 40dB. This makes them ideal for blocking everyday noise or loud equipment like mowers, vacuums, and power tools.

Rugged IP67 Dustproof & Waterproof
Built tough with industrial-grade dust resistance and IPX7 waterproof rating, these headphones handle wood dust, jobsite debris, rain, and snow. They are ideal for workshops, DIY projects, hiking, camping, and other outdoor activities.

80-Hour Playtime & Quick Charge
Powered by a 400mAh battery with a waterproof 2-pin charging port, the headphones get a full charge in 1 hour for up to 80 hours of music or 50 hours of talk time. This ensures less charging and more usage.
