Replacement of the ER20XS ear tips

ER20XS plugs are reusable, but with repeated use, the ear tips may lose elasticity. For best performance and retention, if you use your ER-20XS earplugs constantly, consider replacing them every 3-6 months.

ER20XS earplugs feature a low-profile, stem-less design that sits snugly in the outer ear without protruding.

Technical specifications of the ER-20XS earplugs

ER 20XS 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.

ER-20XS Noise Reduction Chart

ER-20XS provide almost equal sound reduction (20 dB) across the range of hearing. NSR (noise reduction rating) of 13 dB. Standard foam earplugs reduce sound more in the mid and high frequencies, producing an unnatural, muffled sound. ER20XS earplugs reduce sound evenly across frequencies. Speech and environmental sounds are clear, only quieter, allowing for communication and awareness of your surroundings.

    Huge fan of the previous ER-20XS, it appears the new ‘large’ size is the old standard size. Not an issue but I did get a surprise when these new ones didn’t fit appropriately and I had to move up to the larger flanges. Yet to try the foam tips. I also preferred the smaller case these used to come in for storage. However the real necessity is the filter and I still find these great buds for both mixing and seeing gigs.

    These are excellent earplugs for use at gigs. I’m a DJ and needed a trusty pair of comfortable earplugs, and these certainly delivered. The shortened stem makes them incredibly comfortable to use under headphones and even after four hours standing right next to a monitor speaker, my ears felt fresh. They provide great response across frequencies, which is a blessing when you’re mixing music! Having the customisable tips makes a huge difference as well – I discovered that they work better for me using a larger tip in one ear and a smaller tip in the other. Definitely recommend this product, and fantastic customer service from Fleur and team at Pacific. Max B.

    Very happy with these earplugs! They are comfortable, well-hidden when in use, and most importantly they are fantastic for hearing protection. They actually make the sound of the music much clearer, and for the first time I was able to leave a concert without awful ringing in my ears. Felt great. I’m so pleased with my purchase. -A.S.

    I went to a concert recently and only put one of the earplugs in. The sound still sounded great, but the bigger shock was at the end of the concert when I took it out. I could notice a big difference in how my ears felt. The ear with the plug in felt a lot better, and I was able to hear things clearer. Definitely recommend these earplugs for any concert goer! Thanks, Ryan

    Was shipped out to me quickly and arrived within 3 days of ordering. I didn’t expect these earplugs to do much but was blown away by how comfortable and easy to use these are. I bought the extra tips just in case but the standard tips fit my ears fine.

    I have ASD and need hearing protection pretty much 24/7.
    These are suitable for reducing the level of sound but still being able to talk to people or for when driving and wanting to still be able to hear what is going on around me, music, or talking in the car.
    When I need more sound isolation, I have a different plug that has an advertised reduction of 32db that is better suited.
    A little deeper than other plugs I have tried, but not uncomfortable.
    Will be using as my daily plugs.

    Fleur and Pacific Ears were extremely helpful when replacing a lost ear tip on my earbuds. I reached out and they informed me that there was one of my size ear tip left in stock, which they were able to ship out to me very quickly. Great customer service, I would definitely shop here again! Tim D.
