JBL Horizon Overview Wake up with the black Horizon Clock Radio from JBL. This compact radio features dual alarms and LED ambient lights that can be set to gradually brighten in the morning to help you awaken gently. The Horizon wakes you up with one of several original wake up sounds, one of five programmable FM radio presets, music played wirelessly via Bluetooth, or a traditional buzzer. Additionally, the Horizon's two USB ports let you charge your devices on your desk or night-table. The unit features a built-in light sensor that automatically adjusts display brightness to its environment, a large snooze button, a rubberized finish, and a built-in battery system to wake you up during a power outage.
