The Etymotic ER 20 XS do a good job at softening (attenuating) high and low end frequency sounds by lowering the overall volume. Because of the audio attenuation factor, the ER 20 XS are also perfect for motorcycle riders who want to help reduce the wind swoosh or whoosh noise that happens inside the motorcycle helmet
Other uses these earplugs come handy for include airplane situations where you happen to live near an airport or your house happens to be under the flight path of planes. Also, if you are a frequent airplane flyer, these plugs will also help you in reducing ambient airplane noise.
The fabric lanyard necklace that comes with the Etymotic ER 20 ear plugs is a neat touch as it means you can place them around your neck when you're not using them.
The instructions included show you clearly how the necklace is fitted to the earplugs by simply sliding the loops over the earplugs and position the loops against the base of the earplug.
As you can see from the images, the Etymotic ER 20 XS are low profile. They also feature a pull tab to help you remove them.
