Ultimate Ears 400

These stylish, noise-isolating earphones deliver a detailed and immersive sound stage in a comfortable micro design. And the flat cable doesn't tangle, saving time and eliminating hassles.

Tuned by the same engineers who make the custom earphones preferred the world's top touring musicians—for professional sound.

These earphones create a refined, detailed sound stage with high-quality, single-diaphragm speakers tuned to deliver crisp highs, warm mids and powerful bass.

These small earphones sit flush with your ears—for a stylish look that's comfortable and unobtrusive.
