Sound Story
Compared to conventional Dynamic drivers, Balanced Armature drivers produce a broad
and even frequency response with notable vocal clarity. SONY
are tuned for higher or lower frequency response and combined to emphasize certain sound
characteristics.
Balanced Armature Driver
Experience audio ecstasy with 4 newly developed micro-size driver units (full-range + tweeter
+ woofer + super woofer). No matter what your favorite genre, a dynamic performance,
transparent staging, and vivid clarity are par for the course.
Double Layer Housing
A special, high strength magnesium inner housing provides the necessary rigidity for smooth
frequency response while an ABS outer housing suppresses vibrations for clear mid-high
frequency sound reproduction. The result is a total, complete audio performance.
Wearing Comfort
The ultra-compact design of the Balanced Armature driver provides a natural fit inside the ear,
resulting in better, long-term comfort.
Noise Blocking Design
Sony XBA-Series Earbuds provide a comfortable fit that also results in significantly lower sound
®
leakage levels both in or out, allowing you uninterrupted access to your music.
Secure Fit
Hybrid silicone earbuds, in 4 sizes, allow for a tailored fit that further maximizes overall sound
quality and comfort.
Noise Attenuation
Noise isolation earbuds (Included: Small, Medium, and Large) not only provide an outstanding fit,
but also utilize pressure relieving urethane foam to further reduce ambient noise.
