A full range driver, plus one woofer driver and one tweeter, deliver detailed 

vocals, rich powerful bass and clear 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 

Newly developed micro-size driver units (full-range + woofer + tweeter) deliver smooth and 

clear vocals with rich, powerful bass and detailed high frequencies. Get reacquainted with your 

favorite music.

Double Layer Housing

It’s in the details… 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 rich audio performance.

Wearing Comfort

The smaller size of the Balanced Armature (BA) driver allows an improved fit inside the ear for 

better, long-term comfort. This attenuates outside sounds better than headphones with Dynamic 

drivers, resulting in a superior listening experience.

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 utilize pressure relieving urethane foam to further reduce ambient noise.
