The 3M E-A-R Classic is ranked #28 of all 37 earplugs tested by HearAdvisor, placing it in the bottom 50% of products tested. Our lab tests suggest that the 3M E-A-R Classic offers poor Sound Quality and excellent Loudness Reduction. The 3M E-A-R Classic has a Noise Reduction Rating (NRR) of 29 dB. At a common concert level of 100 dBA, you would have approximately 9.2 hours before reaching your daily sound exposure limit (100% sound dose). Exceeding this timeframe increases your risk of permanent sound-induced hearing disorders.

Open ear audio recordings

These sound files replicate the experience of you listening to music without earplugs. For the most authentic experience, please use high-quality headphones and adjust the volume to a realistic, but safe, concert level. Enjoy the immersive sound as if you were there live.

Normal recordings

These sound files simulate the experience of you wearing the earplugs while listening to music. They have been filtered to match the performance we measured in our lab. Compare the resulting sound quality and the degree of sound reduction they offer.

Level-matched audio

Loudness of earplug audio is artificially raised to match that of open ear (to enable evaluation of sound quality only)
