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..

目前還沒實際到演唱會之類的場合嘗試，不過在房間內嘗試後，外面的聲音也可清楚聽到

I purchased these ear plugs along with the Ear Peace high fidelity hearing protection plugs. I ride a naked style motorcycle and experience excessive wind noise every day. (Despite what they say, all helmets are subject to excessive wind noise at highway speeds, just to different degrees based on design.) First off, these ear plugs look cool. Doesn't really matter in my ear, or under my helmet, but when I have them hanging over my jacket via the provided lanyard they look cool. The first thing I did when I opened the package, after admiring how cool they looked, was try them on. Obviously. They slide in very easily and fit snug - the firm base makes it easy to control insert angle and prevent applying to much pressure and hurting yourself. The little pull tab worked as designed to get the ear plugs out, but I found it a little tricky to get the right pressure to get them to pop out. The lanyard does this for me, and with the string, you get plenty of leverage if you need it. I recommend switching to the lanyard immediately. The fit was very comfortable and the first few time I used them I couldn't help but smile. The amount of clarity that these retain while in your ear is mind blowing if you are used to foam ear plugs. It really is exactly like just turning down the volume of everyday life around you. Some frequencies are muffled a little bit, but overall the sound quality is exceptional. I was worried they would be uncomfortable inside my helmet with the large plastic base. This was a non-issue after putting my helmet on and realizing they are seated comfortably inside the ear and do not stick out far enough to bump into anything. Chatting with people over my Bluetooth speakers sounds great, even at highway speeds. Voices are not muffled or sound out of place. If the ear plugs are not properly inserted you will probably notice a resonance in the lower frequencies. It's not a painful sound but the lower sounds have extra buzziness added to them. Just pull over and adjust the plugs appropriately or even continue to ride - I never found it uncomfortable. These were my top pick between the two, I'd recommend these to anyone looking to try a pair of reusable ear plugs! Nothing but praise for these!

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

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.
