Klipsch Image S4

Price: $80, klipsch.com 

We've been fans of the Image S4 since it debuted over two years ago. Comfortable, durable, and powerful, Klipsch's mini in-ear model does well with acurately recreating sounds while keeping most of the distracting background noise—babies crying, subway performers, loud conversationalists—blocked out. Oh, and though we found 'em to be pretty sturdy, if you do manage to break 'em, don't worry—buy the Image S4s new and you're covered by a two-year replacement warranty.
