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.
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.
Each pair of Ultimate Ears CSX earphones come with both Bluetooth and auxiliary cables. Both cables are sweatproof, flexible, comfortable 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.
