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.
