Etymotic Research ER20XS Expert Review
Noise Reduction Rating (NRR) estimates sound level attenuation of an earplug. This decibel rating is determined by standardized testing procedures.
Estimated music sound quality while wearing the earplug, based on our measurements. Higher numbers indicate better sound quality.
Estimated loudness reduction while wearing the earplug, based on our measurements. Higher numbers indicate a greater perceived sound reduction.

State-of-the-art Acoustic Laboratory
Quality data starts with quality recordings, that is why we worked with GRAS to build a no-compromise front end.
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.
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.
Loudness of earplug audio is artificially raised to match that of open ear (to enable evaluation of sound quality only)
