The ER-20 is a low cost, ready to use, one-size-fits-all earplug that replicates the ear’s natural frequency response. Baby Blues are sonically identical, but use a smaller flange designed for youths and others with small ear canals. Both reduce sound levels quite evenly across all frequencies. As a result, music still sounds clear and natural, but levels are reduced by 20 dB so you can listen longer in safety.

The ER-20 and Baby Blues are recommended for budget-minded musicians and concert attendees alike, providing high fidelity hearing protection in clubs and concert arenas for just $12 per pair ($15 for the ER-20 Pro, which substitutes an aluminum storage case). Don’t settle for the muffled sound of foam earplugs. Invest in a pair of ER-20 earplugs today.

The ER-20 uses secure triple-flange earphones for a secure seal and comfortable fit, and is supplied with a plastic storage case.
