Effective, not distracting, low profile
I use these in one of my fitness classes where the teacher plays music very loud.  They definitely work to reduce the sound to a more comfortable level. I have found that I can still hear people talk, so that is good too.  They fit comfortably in my ear.  They are certainly noticeable but not at all distracting.  I also like that they are low profile, being clear and fitting pretty far into the ear, so it's not obvious I'm wearing ear plugs.  I highly recommend these for instances where you want to just cut the sound down a bit.  I could see where certain people would want more sound to be blocked, but these are perfect for my needs.
