I have a couple pairs of these that work well. Sound qualify is pretty decent, they don't come loose while running/lifting, and have been impervious to sweat.

I actually could not stand the regular earbuds already. I always lost my right earbud mid run. Never the left earbud, just the right one. Ugh.

I purchased these. I'm happy with them. They don't move at all once I've put them in, they block out sound really well, and the sound is good.
