Optimized for audiophiles.
Calling all music lovers: this headphone's for you. The pinnacle of the XBA Series, these XBA-4 in-ear headphones boast a total of four Balanced Armature driver units (a full range driver, tweeter, woofer and super woofer) to deliver an incredibly balanced spectrum of crisp, radiant highs and deep, breathtaking bass. Precision engineered for music enjoyment, brace yourself for a premium listening experience like no other.
Designed for discerning audiophiles, XBA Series in-ear headphones are outfitted with Sony's newly
developed Balanced Armature driver units engineered for crisp, balanced sound of incredible depth
and precision. Infused with premium audio technology, even the most subtle musical nuances are
delivered with tremendous clarity and detail.
Balanced Armature Drivers
Meticulously pre-tuned by Sony engineers, four Balanced Armature driver units (full range, tweeter, woofer and super woofer) reproduce a broad, finely balanced range of sound—from soaring highs to bellowing bass, and everything in between. Plus, these micro-sized drivers are engineered to emphasize key sound characteristics to enhance your music.
Double Layer Housing
A specially made inner housing constructed of liquid crystal polymer holds the driver units rigidly
in place for super smooth frequency response. Enclosed in an ABS outer housing that suppresses
unwanted vibrations, this innovative double layer design delivers crystal-clear mid to high range
sound and overall crisp, rich audio.
Long Lasting Comfort
Because Balanced Armature drivers sport an ultra compact design for a smaller overall form factor,
they slip easily inside the ear for a snug, more natural-feeling fit. The result? Reduced ambient
noise and long-lasting comfort and wearability—even after hours of non-stop listening.
Noise Blocking Design
Lock in the sounds of your favorite songs, and block out disruptive background noise. Because Sony XBA
Series in-ear headphones boast a noise-blocking design and a snug, comfortable fit, they prevent sound leakage—both
in and out of the ear—so you can enjoy your music without annoying your neighbor, and get lost in a
distraction-free listening experience.
With four sizes of hybrid silicone and three sizes of noise isolating ear cushions included, you can choose
the best fit for your ears to maximize overall sound quality and comfort. With the perfect-fitting pair,
your XBA Series in-ear headphones stay securely in place—even during strenuous exercise—while keeping ambient background
noise at bay.
