The Ultimate Ears 900s Noise-Isolating Earphones were designed to make your music come alive–to reveal layers and details you never knew were there. They transcend a technological device–unlocking the depth, richness and emotion of the music you love.
QUAD ARMATURE DESIGN
The UE 900s features four precision-balanced armature speakers per ear—two for low end, one for mid-range, and one for high frequencies. Nothing short of a revelation, the UE 900s beautifully reproduces the highest highs and the lowest lows.
THREE WAY CROSSOVER
A three-way crossover routes highs, mids, lows to the optimal speakers, delivering professional-grade clarity, separation and acoustics.
DUAL BORE AUDIO PATHS
Our patented dual bore audio paths keep signals separate as long as possible, giving you the unparalleled clarity to hear the spacing and unique timbre of each and every instrument.
