I've used those too, Ryan.  They are great.  For something to keep handy in your pocket, Eargasms can't be beat.  They come in a machined aluminum case and are excellent at noise reduction.  The problem is, I can't carry on a conversation with them in.

They're pricey, but twice WOOT! has had them half off, and I bought the limit of three each time.
