Wake up in the morning wanting some bass? Then start your day the KitSound way with the Boom Clock. Before busting some shapes (or whatever you get up to) in dream world, select a tune that you know will get you going in the morning and set the wake up time and volume. The Boom Clock is just the right size for your bedside table, making it the serious choice for your boudoir. The featured sub woofer and sound quality means that it is just right kicking back or rocking out. We have jammed in RF shielding, which means that you do not need to put your iPhone into flight mode when it is docked. This means that if somebody needs to get hold of you in the middle of the night, they can (unless you don't want them to, of course!)
