Etymotic Hi-Fi Muscians Ear Plugs
ER-20 Ear Plugs w/Carry Case and Cord. ER-20s are ideal for concerts and music performance. These plugs do not distort the music so you can hear the full dynamic range and still get the protection you need. Standard size fits average to small ears & comes in frost color only. The large size fits average to large ears.
ER-20 Hi-Fi Ear Plugs reduce the volume by about 20 db--just enough to prevent damage to your hearing, but not so much that you lose the enjoyment of the music. The ER-20 has an NRR of 12 rather than 20 because the frequency weighting used in the NRR calculation assumes blocking of higher frequencies more than of lower frequencies, and these plugs do not do that. They are designed to let you hear the full range of music, without distortion across the frequencies.
ER-20 plugs are durable, washable, and long lasting. With proper care they will last for months even with daily use. Sold with sturdy carrying case and cord.
