UE BOOM 2 @ techPowerUp
 

Ultimate Ears' line of BOOM speakers recently got updated with the arrival of the BOOM 2 speaker. The BOOM 2 shares the same footprint as the original BOOM, but has been updated with a few nifty features. Among these is wake-by-bluetooth and stop/start/pause slapping capability.
