Two Jack Mini Amplifier

Many personal players do not provide quite enough volume to blast over wind noise or past earplugs. The Boostaroo can help. Plug it into the audio jack of your radio/scanner/whatever, then connect your helmet or earplug speakers. Voila, the sound level is increased by about a third. Input device volume adjustments remain functional, but everything tops at a greater volume. Clearly and cleanly, too. About a 12dB gain in a typical ear speaker. Two AA batteries (not included) last about 20 hours. There are two jacks so a passenger can listen along. 40mw per channel.
