Custom Sound Profiles

With our proprietary EQ app, you can choose from a variety of presets optimized for different listening experiences. Find the perfect amplitude for podcasts, classical, jazz or heavy bass -- or play around with the frequencies to match your personal taste and then store them in your Bluetooth cable.

All Day Comfort

Having a secure, custom fit also provides the most important benefit if you use your earphones for extended periods of time -- all day comfort.  Ultimate Ears are designed so you can travel, work, listen at leisure and forget about common irritations like ear soreness.

Noise Cancellation

Ultimate Ears are custom fit to create the closest-fitting seal possible between the earphone and your unique ear shape. The advantage of this fit is the physical exclusion of external noise, or what’s called passive isolation. Passive isolation blocks out the sound that is trying to get in, versus introducing new sounds to block out ambient noise. The result is 26 decibels of noise cancellation, as much, or more, than most other earphones on the market.

Swappable Cables

Each pair of Ultimate Ears CSX earphones come with both Bluetooth and auxiliary cables. Both cables are sweatproof, include a mic for making phone calls and feature our award-winning cable connection system, allowing for a quick and easy transition from your Bluetooth wire to your hard-wired, so when your battery dies, or you want to plug into in-flight entertainment, you can do so with ease.
