These debuted about the same time as Hit Clips but didn't last very long. The sound was better than Hit Clips, but the three watch batteries to run the boom box are more expensive than the single AAA battery for the Hit Clips. Still, I kind of liked how they looked. (still no volume knob though) Yaboom also marketed full-length somgs on a keychain and dolls of singers that played their music, such as Christina Aguilera
