Triple the available headphone ports and double the volume that comes through them to your computer speakers or headphones with UpBeat Audio's Boostaroo Amplifier/Splitter. No batteries needed!
Double the Sound
Do you ever have trouble hearing your headphones or your laptop speakers over the noise and din around you? UpBeat Audio's Boostaroo is the answer! Just looking at the specs, you can see that (depending on the ohm rating of your headphones) audio output is doubled with less than one percent harmonic distortion.
Triple the Ports
The Boostaroo, as well as amplifying audio, also splits the signal into individual stereo channels to drive boosted sound into three separate headsets or speakers. That way, when using your laptop to watch a movie on a plane or in a car, nobody has to be left out.
Zero Batteries
Unlike other Boostaroo models, this one comes with both a USB and AC adapter, so you don't need to single-handedly keep your local battery store in business. It can draw the necessary 5V of power from either your car's cigarette lighter or your computer's USB port. Welcome to unlimited freedom, my friend.
Perfect for Anything,
Use the Boostaroo with your laptop, PSP, Nintendo DS, Bluetooth headphones, or anything else you can think of that you may want to hear better or listen to with a friend.
