 Balanced Armature. A full range 

driver, added tweeter, plus two woofers, deliver rich profound bass, clear 

vocals, and bright, clear mids and highs. Rediscover every note and all the 

emotion of your favorite music with the world’s only drivers optimized for 

music enjoyment. 

Sound Story

Compared to conventional Dynamic drivers, Balanced Armature drivers produce a broad 

and even frequency response with notable vocal clarity. SONY

®

 Balanced Armature drivers 

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.
