The WI-C100 redefine entry-level wireless in-ear headphones. With Sony’s exceptional sound quality, they offer a rich listening experience while a long 25hr battery life and splash-proof design give you peace of mind when you’re out and about. They’re also compatible with the Sony | Headphones Connect app, so you can adjust sound to suit your tastes. Enjoy up to 25 hours of non-stop music. And if your headphones are running low on power, a 10 minute quick charge will give you up to 60 minutes of playback. When an original music source is compressed, it loses the high-frequency elements that add detail and richness to a track. Our Digital Sound Enhancement Engine (DSEE) faithfully restores them to produce high-quality sound that’s closer to the original recording. Tailor your sound to your personal preference. Choose from a variety of presets to match the genre of music you’re listening to, or create and save your own custom presets using the equaliser feature on the Sony | Headphones Connect app. The sound tuning is intentionally designed to be well-balanced from low to high frequencies, and vocals are natural and clear. So the WI-C100 headphones match any music genre. With an IPX4 water resistance rating, splashes and sweat won’t stop these headphones – so you can keep on moving to the music. Lightweight and portable, the WI-C100 headphones have a flexible neckband that makes them even easier to slip into your bag when you’re on the move. The WI-C100 headphones drape over the back of your neck for a stable fit, while the housing follows the contours of the ear for maximum comfort.
