The iD83 is a dual alarm clock radio for iPad, iPhone and iPod that lets you charge your iPad, iPhone or iPod and lets you wake and sleep to either one, to a custom playlist, or to FM radio. A Sync button syncs the clock to your iPhone (which is always current via cell phone towers) to set the time quickly. The iD83 allows you to set two separate alarms with different times on different days with our 7-5-2 feature. The iD83 also includes 6 FM presets, EQ controls and 3D sound and Reson8 sound technology for an exceptional audio experience.
