Ultimate Ears UE-10 Pro in-ear headphones
All of a sudden, it seems there's a renaissance in in-ear monitors. Used to be there was just <A HREF="http://www.stereophile.com/headphones/805">Etymotic</A>, but now Etymotic, <A HREF="http://www.stereophile.com/headphones/504shure">Shure</A>, and <A HREF="http://www.stereophile.com/headphones/1204ultimate">Ultimate Ears</A> are all producing high-performance in-ear headphones. It's almost enough to make me suspect we audiophiles have become a marketing juggernaut.
