The Boostaroo Portable Headphone Amplifier gives a 40% increase in sound with no distortion, increases the battery life of tape players, and allows a listener to hear a book on tape in noisy environments such as a plane or even on a riding lawnmover. It's ideal for DVD Players as it will power mini-speakers as well as headphones, and it works great for CD Players, MP3 Players, Tape Players, and Mini-TV's that are popular in new Vans. Other uses are with the Gameboys, Nascar scanners, Helmet Intercoms and more.
