Logitech Ultimate Ears 400 Noise-Isolating Earphones

Never miss a beat
Crisp highs. Warm mids. Powerful bass. When nothing but the music matters, our 400s deliver a balanced frequency response and a highly detailed soundstage. The high-quality diaphragm drivers were designed and tuned for music lovers who want to hear the music just as it was recorded.

Fit and finish
Our 400s feature a sleek, micro design that sits flush with your ears—for a stylish look that’s comfortable and unobtrusive. The flat, painted cord doesn’t tangle. And the tapered silicon ear cushions fit more naturally than traditional “square” ear cushions, or use the included Comply™ Foam Tips for maximum comfort and noise isolation.
