The pinnacle of premium
For sound quality and control, these XBA-4iP in-ear headphones beats them all. Proudly at the pinnacle of Sony's XBA Series, they boast a total of four Balanced Armature driver units—full range, tweeter, woofer and super woofer—to deliver a titillating spectrum of crisp, radiant highs and deep, penetrating bass. And with the added convenience of an in-line remote with built-in mic, you can control your compatible iPhone^®, iPod^®or iPad^® for easy listening and hands-free calls.

Sensational Sound
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.

Hands-free Calls and Easy Control
Take, make or end phone calls—or skip to the next track of your playlist—using the in-line remote with built-in mic. With full integration for your iPhone, iPod and iPad, controlling your music is a breeze. Activate the VoiceOver mode with the simple press of a button, and your iPod will even tell you what song you're listening to (enabled devices only).

Double Layer Housing
A specially made inner housing constructed of high strength magnesium 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.
