Protect your most valuable equipment
Musicians put guitars in cases, and processors in racks, but often they do not protect their most valuable piece of equipment -- their ears. Get maximum protection against noise and volume levels without changing the tone and balance of the music. Highs and lows are still there, they're just a lot quieter.

Flat response
Tuned acoustics take the "muffle" out of hearing protection. Instead of blocking high-frequency noise more than low-frequency noise, as do conventional hearing protection, the plugs' unique design blocks sound of all frequencies almost equally. Furthermore, attenuation is optimized to avoid overprotection of moderate exposures of less than 95 dBA. Speech and music remains crisp and natural-sounding. This performance makes the ER20 a great choice for musicians, engineers and others who have a particular need to clearly hear sounds while in rehearsal or at the gig.
