ER20XS High Fidelity Earplugs The ER20XS is the next generation high fidelity Etyplug, reengineered to fit in an eXtra small compact form factor.

The ER20XS is a great choice for those who wants to protect their hearing from loud sounds, while at the same time continue hearing surrounding music, speech, and other meaningful signals:

· Musicians.

· Rock concerts.

· Loud vehicles – bikes, scooters, motor boats, snowmobiles, etc.

· Motorsports.

· Travel.

· Power tools, machinery.

ER20XS Earplugs are reusable, low-profile, with a stem-less design that sits snugly in the outer ear without protruding. This makes it discreet and comfortable to wear under hats, helmets and other headgear.

ER20XS come with a small, flexible pull tab that allows for easy removal, an easy-to-install neck cord and a carrying case.

Performance matches Etymotic’s original high-fidelity Etyplugs developed for musicians. Having the identical response through 4 kHz, with an improved high-frequency clarity above 4 kHz, without compromising protection. Richness of music is preserved; speech remains clear, just quieter with 20-dB equal sound reduction across the spectrum of hearing.

Traditional foam earplugs do not compare with high fidelity ER20XS Earplugs. The well-known bright-colored red or orange foam plugs muffle sound by reduce mid-range and high frequencies resulting in muffled speech and music. On the opposite, while ER20XS Earplugs reduce noise levels evenly, they preserve clarity of speech, communication, and the richness of music.

ER20XS Earplugs are reusable. With heavy use the material can weaken and could break. Replace every 3-6 months.


· Reduce risk of hearing damage for many noisy occupations as well as noisy venues, such as airshows, parades, athletic events and motor sports.

· Low cost.

Significant noise suppression.

Today, rode my PanAmerica all morning with my Motorsport etymotic’s. After a break when I drove off w/o the ear plugs I was shocked how much louder the bike was.

Small, Affordable, Comfortable and Effective

I just bought several more pairs of these so that I can have a pair stashed just about everywhere, e.g., my car, my briefcase, my golf bag, my double bass bag, jacket pockets, etc. Having owned ER products since my first pair of custom Musician Plugs purchased probably 25 years ago, I've been impressed with the company and its products. Even though I've worked extensively as a bassist, I can still hear 16Khz at aged 73 which is a tribute to the quality of the products and the ever-increasing need to use hearing protection. Movies, airplanes, restaurants, clubs, etc. are all too loud and it pains me to see the number of people, particularly young people, doing permanent, irreversible damage to their ears out of total ignorance. These plugs would serve these people well since the sound is so natural and unmuffled.

Working a small welding shop. They cancel the loud noises enough but allow the speech to still be heard clearly.

Good Cost Effective Option to Noise Cancelling Headphones

I wanted a means to reduce ambient noise. Noise cancelling headphones seemed like overkill, so I purchased these earplugs to try out first. I am quite happy with the results.

Great Ear Plug for Musicians

This earplug mutes just enough sound level without sacrificing the sound details that musicians need. Great for use in enclosed areas to filter out echo, or while standing in front of a loud monitor. The size customization allows for a more comfortable fit than the original plugs.

Great earplugs

Earplugs fit well and are consistent in their comfort. I love wearing these to movies, concerts, and bars. A good investment that's durable and reliable.

Use these earplugs while riding motorcycle. The road noise is almost completely gone which allows music to be understood and heard a lot better.

Work very well

These work as described. They effectively attenuate sound while preserving musical dynamics. I wear them at all rock concerts I attend.

Bought them for an electronic music show and they did not disappoint

Went to a club that was hosting one of my favorite djs. The room was super tiny but they had their systems nearly max volume. The plugs just made everything quieter, but not muffled. I took them out just to see if they were doing anything and the difference in loudness was so painful, so I knew they were doing their job. I def keep them on me at all times now and feel more confident attending more shows.

Work great for concerts

Got these to use for a concert. We were impressed with them as they blocked out the dangerously loud noise and made the music sound clearer. Bought another 4 sets for our kids. So far, I’ve seen Tool, Santana, Korn, and System of a Down using these earplugs and I didn’t leave any of the shows with ringing ears. Highly recommend.

Great for Concerts – Sound is Amazing

The absolute best thing about these Earplugs is that everything still sounds the same, just at lower volume. I had started wearing hearing protection at concerts, I love live music, but the foam plugs always affected the sound. I would always find myself taking the plugs out after adjustments failed to improve the quality of sound and would always end up with familiar ringing in my ears, or I'd feel like I didn't get the full experience due to the muffling.

These Etymotic Earplugs have been a gamechanger. The music sounds the way its supposed to without any of the side effects after the fact. That, and they are super discreet, and portable, so I don't have to deal with larger overhead protection.

I absolutely recommend these plugs (I bought the 20Xs) to anyone who enjoys live music, especially at small venues, and would suggest you buy before you think you need them.

Fantastic product!!!
