Logitech's purchase of Ultimate Ears gave birth to some great portable speakers and headphones. But our favorite, and arguably the best of the new line, are the 900 headphones. Modeled after the stage monitors professional musicians use when performing, the 900s wrap around your ear for a snug fit that blocks out all outside distractions, leaving you with the beautiful sounds pumped out by its quad-armature driver design.
