Etymotic ER38-18CLX 大サイズ クリア 3フランジ イヤーチップ

The triple flange seats so deep and snug that I forget they're in, and the long stem makes them easy to grip when pulling them out. These large tips block out my neighbor's lawn mower completely during my lunch break.

I was worried the large size would be too big, but the long stem keeps them securely in place even when I'm moving around a lot. Definitely a snugger fit than the medium version I tried before.

The three-flange design slides in smoothly and seals much better than my old foam plugs. I can hear conversations clearly at a concert while still blocking the damaging loudness. They feel secure and comfortable for a full show.
