## Description

Product Description Etymotic ER-20XS universal fit earplugs are the highly-awaited next generation of Etymotic's industry-leading ETY-Plugs High Fidelity Earplugs. They feature a stem-less design, with a low profile that conforms to the plane of the outer ear. This makes them particularly comfortable to wear under hats and other headgear. The universal fit version comes with three interchangeable pairs of ear tips for more fitting options. Etymotic ER-20XS 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. ER-20XS provide almost equal sound reduction of 20dB across the range of hearing. ER-20XS earplugs come with a small, flexible pull tab that allows for easy removal, an easy-to-install neck cord and a carrying case. ER-20XS ear tips are interchangeable and it can also be used with foam ear tips with essentially no change in response. Healthy hearing for a lifetime. Directions 1. Remove earplugs from packaging. 2. Choose the appropriate ear tip size. 3. Insert earplugs into ears. 4. Ensure a proper seal for noise reduction.

Review: Wouldn't be without them. - These are great, really wouldn't be without them now. Much, much better than the Alpine ones I tried first; these really do keep a clean sound. I've enjoyed gigs more since having these; I think they may even improve the sound, taking away distorted loudest elements leaving a more balanced image.
Review: Imrovements on the original ETY-Plugs, a viable choice without over-spending - So I have the ACS ER-20's, also known as Etymotics Ety-Plugs which are very well known and recommended. I had a problem with the fitting of these in one ear only, I had to push them in too deep it was uncomfortable. So I ordered these in large size hoping they would help. Their profile is much lower than the Ety-Plugs so aesthetically they are superior. The comfort, for me anyway, is also superior - they don't need to be pushed in so deep as the originals. They stilll don't come as comfortable as wax / foam but they sound just as good as the original model which are highly regarded for live music. The fitting is fine for the duration of a concert but I wouldn't want to wear them all day long. Of course all ears are different but these are designed pretty generically so you have a high chance of getting on with them. If you have no previous experience with live music sound protection I would recommend these as a first try. They are probably as good as you will get for this price margin, although obviously they won't come close to custom moulded ones. They are designed by a highly professional and reputable hearing specialist so you can rest-assured be happy with the safety and sound quality they provide.

## Questions & Answers

**Q: How do i know which size to purchase? how do they fit compared to small, medium, large earbuds for listening to music?**
A: I'm not the best person to answer perhaps. I found them useless. No better than cheap chinese plugs I use for swimming. Why did I buy them? I've owned 4 pairs of etymotic headphones and consider them the best in the world. I've owned custom mould UE5s and Etys are better and their fit with the triple flange (for me) is perfect so ... I'm an Ety fan and expected these to be great. Perhaps I should have persisted and of course take other people's (positive) views into account...

**Q: What would happen if you used them for shooting**
A: Never used them for shooting so I couldn’t say. I do know that there are plugs designed to protect the ears from the noise of guns. Best google it to find out.

**Q: Are these washable, and if so can they be lent to someone else after washing?**
A: The rubber bell ones, yes, although I would pop them off the hard plastic base before gettnig them wet. As for lending them to someone else, I'm not sure I would personally recommend that without dousing them in milton fluid before using them again myself.

**Q: Can they be returned if they don't fit?**
A: You would need to ask Amazon as I wouldn't think so. I would always recommend the more expensive version as it has all sizes and you are guaranteed a fit,

### ⭐⭐⭐⭐ Tricky fit, but effective
*by H***Y on 7 January 2026*

Overall, the plugs worked well, nice and discreet, dampened the noise of a loud concert well but without losing fidelity (I tried with and without and the sound was very similar, if anything, cutting some Dbs helped to hear more detail in the music. The only issue that I had was that I initially found the plugs horrifically uncomfortable. A lot of reviews talk about needing to insert the plugs quite deep, and this caused acute pain for me. It might be that I have smaller ear cannels, but inserting until I felt a seal and then even backing off a little from there seemed to have a good reduction of noise whilst not being painful. I'm not a stranger to wearing ear protection, but I don't really get along with the triple flange of these plugs. Possible even this smallest size was a little too large for me. Overall I will continue to use them, but once they wear out I might try some other with a different plug design for extra comfort.
