Good to know, thanks!

Yep, been using Etymotic ones for both concerts and riding motorcycle, and I love it. It works just right, and for $15 feels like worth every penny (ER20XS; went with that one over the regular ER20 because of a lower profile shape). They are nearly indestructable and super easy to clean too (relevant if your ears tend to produce a solid amount of earwax). Had to replace them once over the years and only because i lost my original pair.

Really comfy, non-descript, very easy to put in and remove, and only blocks out the annoying stuff while making the necessary stuff more prominent (with music, it would be amplifying guitars/synths as well as speech, while cutting down a bit on drums; with motorcycle, it would be amplifying breaking sounds, sirens/horns, and, again, speech, while cutting down on wind and engine noise). I can wear them for hours, eventually forgetting that I even have anything in, despite usually being really sensitive to earbuds and not being able to wear them for prolonged periods of time.

I've used Etymotics for years. Cheap ($20), comfortable, easy to carry, and a wonderfully flat frequency response (at least compared to cheap foam plugs). Also, Etymotics makes great wired ear buds.
