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 eartips 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 eartips are interchangeable and it can also be used with foam eartips with essentially no change in response.
Healthy hearing for a lifetime.
ER-20XS earplugs are discreet and have the identical response of ETY-Plugs through 4kHz. Above 4 kHz they have improved high-frequency clarity without compromising protection. ER-20XS lowers sound levels evenly so that music and speech are clear and natural, not muffled as with other earplugs.
ER-20XS earplugs come with three interchangeable pairs of eartips including standard and large 3-flange tips, and foam eartips. The foam eartips work in conjunction with the advanced technology in the earplug itself, offering protection and clear communication.
With improved design including low-profile and stem-less housing, the ER-20XS reside snugly in the outer ear without sticking out. This makes them perfect for use under hats, helmets and other headgear. Includes a small, flexible pull removal tab, an easy-to-install neck cord and a carrying case.
ER-20XS earplugs are reusable, however with repeated use the eartips may lose elasticity. For best performance and retention, if you use ER-20XS earplugs constantly, the eartips are best replaced every 3-6 months.
