+1 for the ER20s. I've got some of the early Loops (no inserts or anything fancy) which are decent enough (and can be used for sleeping in an emergency.) Also got some of the early Flare Audio titaniums which do a decent job.
(For sleeping I buy the Leight Laser Lite in bulk because anything with a stiff/solid stem tends to be uncomfortable. They also work reasonably well in gig scenarios.)
