Everytime something on the game would cause a louder than normal sound, the unit would give a little vibrating buzz. The sound through the stereo speakers was fuller and louder than the Gameboy Color's built in speaker. All in all, I can't really recommend this product because I have not been able to get a unit that works consistently. If you just need a rechargeable battery pack for your Gameboy Color, I would say that this might be a good choice. Incorporates a 10 hr rechargeable battery.
Rubberized grip is easy to hold.
