The interface of the JBL Horizon alarm clock allows for subtle wake-up experiences based on individual preferences. A gradual warm light starts the awakening process gently, ten seconds before the alarm rings. The alarm sound can be chosen from various wake-up sounds, radio stations or music stored on the smartphone. A built-in light sensor adjusts the display brightness according to the surrounding light level. A sleep mode, which automatically turns off the music after a certain time, and a snooze button both enhance user convenience.
