Etymotic Research ER20XS-SMF-P High-Fidelity Earplugs, 1 Pair, Standard Fit, Polybag Package Size: Standard Fit Model: ER20XS-SMF-P

Poor...very small and ineffective..

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.

Muy satisfecho con el producto. Atenúa el sonido sin distorsionar nada. Merece la pena lo que cuestan. Tienen mejor rendimiento que los Loop a la hora de atenuar sin distorsionar. Un 10.

I always carry these with me. Very confortable to wear for long hours. Excellent noise reduction

I bought these earplugs a couple weeks ago. I have owned the larger version of these for about a year. These are a lot nicer in that they don't protrude obnoxiously from your ears. They smaller ones sound more realistic to me, but I could be wrong, as the larger ones sound great too. They really reveal just how awful my drum kit sounds (haven't replaced the heads in 8 years). I love playing guitar with them, since the tone isn't muffled like with normal over-ear hearing protectors, and I don't get as tired of them as I do playing through headphones with an amp simulator. I play my guitar at a volume that isn't crazy, but definitely too loud for prolonged exposure. I was too lazy to go to my car to get my earplugs (I don't want to not leave them in the car, because I'll forget them right before I go to a concert, and regret it very much), so I bought these for the jam room. It's nice being able to feel the riffs in your chest without going deaf. The only complaint is that these earplugs really expose just how much gunk builds up in my ears, and if it builds up too much, things become unpleasant.

Fui a un festival de musica electrónica por 2 dias (estuve casi al frente) y me ayudaron muchisimo estos earplugs. No termine con el zumbido habitual al final del concierto ni nada, asi que cumplen con su propósito. El detalle es que despues de un rato molestan y al menos yo los senti bastante incomodos, tenia que quitarmelos y volvermelos a poner para sentir algo de alivio. Los recomiendo de todos modos porque su proposito es evitar daño auditivo y lo cumple.
