ER20 HIFI Filtering Earplugs

The ER-20 Hi-Fi earplugs have a triple flange construction and provide an inexpensive, "high-fidelity" earplug that can be used in a variety of noisy environments.

Mainly used as an inexpensive Musician's Earplug, these plugs have principles to allow the user to still hear through a inserted resonator within the stem that allows outside tones such as vocal or musicial to be heard.

• Low cost
• Associated 20dB attenuation
• Clarity of sound and pitch
• Good frequency response accuracy
• Speech is understood more easily in high level noise

The ER-20s are DIFFERENT than conventional earplugs. They actually reduce the dangerous sound level evenly (using a tuned resonator and acoustic resistor) to preserve the balance. You still hear the blend clearly, "feel" the bass, and are able to distinguish each tone.
