Comfortable. Unobtrusive. Easy to get in, and they stay that way.
I've only had these for about a week, and don't use them that often, but they're great!<br />When I first put them in, I found they far exceeded my expectations.  Every other earplug I've ever used is uncomfortable and difficult to put in. These immediately fit very well, are soft and comfortable, and are unobtrusive. I haven't used the different tips they supply, since the ones that are already on the earplugs work so well, but the options are nice.<br />Also they're unobtrusive, so wearing them in public doesn't feel weird.<br />Lastly, I used them to take a nap (because they're building a new house across the street from us) and they felt comfortable, even though I sleep with my ear into the pillow.<br />They're a good purchase.<br />I'm not a musician though, so I can't speak to the quality of sound.
