ER20 Ety Earplugs are High fidelity, ready-fit earplugs

ER-20 Ety-Plugs - Ideal for musiciansETY Ready Fit Plugs are the world’s highest fidelity non-custom earplugs. They reduce most noise to safe levels while preserving the clarity of speech and the richness of music. ETY Plugs are configured to replicate the natural response of the ear canal so that when sound enters the earplug, it is reproduced unchanged, exactly the same as the ear would hear it, only quieter.

ETY Plugs are reusable. With heavy use the material can weaken and could break. Replace every 3-6 months.

The ER-20 Ety-Plugs have many Benefits

  • Ety-Plugs reduce sound levels evenly so that music and speech are clear and natural, not muffled as with other earplugs
  • Reduces risk of hearing damage for many noisy occupations as well as noisy venues, such as airshows, parades, athletic events and motor sports
  • Enhances the music experience for audiences while protecting hearing
  • Lets musicians hear their own instrument and their blend with others

The Features of the ER-20 Ety-Plugs

  • Low cost
  • Ready-fit
  • Available in 2 sizes (same sound reduction) – standard and large*
  • Reduces sound approximately 20 dB at all frequencies

* All ears are different. It is impossible to predict the size of an ear canal by the appearance of the outer ear, or by a person’s physical size, age or gender. Two sizes of ETY•Plugs fit almost 100% of ear canals. Recent studies of both fit and seal, conducted at Etymotic Research and an independent lab, showed that the smaller of the two sizes fits the majority of ears and is now designated as standard fit.

ER-20 Ety-Plugs are Ready-Fit plugs

  • Regular use of these high-fidelity earplugs while practicing, performing and listening to music will protect hearing from the cumulative effects of overexposure to loud sound throughout life.
  • A little time may be required to acclimate to these earplugs. Many musicians report that they hear their own instruments better, as well as the balance with those around them.
  • ETY Plugs are reusable, but with repeated use, the eartips may lose elasticity. For best performance and retention, if you use your ETY-Plugs constantly, replace them every 3-6 months.

ETY-Plugs exploded view


ETY Earplugs use a tuned resonator and acoustic resistor to replicate the natural response of the ear canal. This unique construction, combined with Etymotic’s proprietary sound path, reduces sound levels evenly across the frequency range without changing the sound quality. Result: Music and speech remain clear, but quieter and safer.

ETY Plugs provide almost equal sound reduction (20 dB) across the range of hearing. Foam earplugs reduce the high frequencies, resulting in muffled speech and music.

    Hi Pacific Ears,
    I’ve previously bought the standard ear plugs. My friends and I use them frequently at gigs/festivals. They’re a life saver and make a huge difference. I no longer leave events with ringing ears for days, plus it doesn’t affect the sound quality at all. They come in a small container which is super convenient and can be attached to a key ring. I’ve also just purchased the ear plugs for musicians, for a Christmas present. For such a small price, it’s definitely worth protecting your hearing. Shipping is extremely fast too. Thanks so much, would highly recommend.
