The most important thing to remember about Plugfones is that they're earplugs first and audio second. As such, the entire Plugfones line is tested and compliant with ANSI S3.19-1974 noise reduction standards and meets NIOSH criteria. When used as directed, the Basic is certified for a Noise Reduction Rating (NRR) of 25 dB. For environments with high levels of noise, it may be necessary to use over ear protection such as earmuffs in conjunction with Plugfones products.
Plugfones have been independently tested to meet U.S., E.U., and Australian standards. For more information, visit our Safety page.
