I'm in love with Loops earplugs. I bought some near the start of the semester to just wear when eating in the cafeteria, and they were great. Now I wear them in grocery stores (when I remember) and I even got to use them at a concert two weeks ago! So I decided to upgrade to the Switch version, since I found myself popping the mute into the Engage model I had pretty often. I didn't particularly like the fully plugged-ear sensation I got with the mutes in though, so I hope the Switch doesn't have that sensation.
