Plugfones manufactures innovative earplug-earbud hybrids combining high-fidelity audio with ANSI-certified hearing protection for industrial and recreational use.
プラグフォン is a specialized audio brand that bridges the gap between industrial hearing protection and consumer headphones. Designed for use in loud environments such as construction sites, factories, workshops, and during motorcycle riding, Plugfones products function as both ANSI-rated earplugs and high-fidelity earbuds. This unique hybrid design allows users to listen to music, audiobooks, or take phone calls while significantly suppressing harmful external noise, helping to ensure compliance with safety standards like OSHA when used correctly.
The brand's lineup includes rugged wireless models like the Mercenary and Liberate series, featuring Bluetooth connectivity, long battery life, and noise-isolating microphones. They also offer wired options for consistent playback without the need for charging. With proprietary technologies like SoundSeal and WorkSafe volume limiting (on specific industrial models), Plugfones aims to make work more enjoyable and safe by integrating entertainment with essential hearing health protection.
