Klipsch X11i Earphones

From the tiny buds to the angel-pasta-thin cords, the X11i's are the lightest earphones in the world. But that's not why they cost $300. The price is a product of the audio, which is clean and crisp. Since the bass isn't overwhelming, they're as well suited to music as movies. And since the negligible weight keeps the buds from bouncing out of your ears during exercise, they're a better alternative to the ugly, ear-looping models that are marketed for the gym.
