Super Splitter
Wildly popular all over the web, the Boostaroo Revolution delivers exactly what it says it does. It expands any single stereo output on MP3 players and other devices to two separate boosted ports.
Stellar Sound
And the output in both ports is boosted by 11.5 dB (granted have a decent pair of headphones or speakers) with no more than one percent harmonic distortion. Even better, the signal is split into three channels creating a distinct surround sound effect without sacrificing quality.
Special Note - Power Requirements: VDC minimum: Cutoff may be considered as 0.8 volts per cell. Two AAAA cells are required. Use of alkaline batteries is suggested for longer playing time. Also works with rechargeable batteries; nickel-metal hydride type preferred. Battery life estimated at 20 hours, depending on headphone impedance and sound level. Input must be unplugged when not in use to conserve battery life.
