ER20XS, Etymotic Research
ReviewThe ER20XS are produced by Etymotic Research (ER). They are positioned as reusable earplugs with high sound quality. The ER20XS are a successor product to the ETY 20 earplugs. They are similar with the exception that the stem length of the ER20XS has been reduced significantly. This makes them less visible that the ETY 20. The ER20XS provide medium sound protection.
The ER20XS is a good choice for listening to music. The sound quality is good and much better compared to foam earplugs. The ER20XS provides medium sound reduction. The sound quality is so good, that one can still easily converse with other people at normal loudness. However, if one is in an environment with really loud music, then the ER20XS might not offer enough protection and stronger earplugs should be considered. Foam earplugs offer more protection, but much less sound quality. If money is not an issue, then the ER25 earplugs are an alternative with more sound reduction and even better sound quality than the ER20XS, but they are custom made and much more expensive. Also have a look at our article on listening to music.
