The Sound Demon Vest is a personal apparel speaker system. 
The water resistant Taslon vest contains two sets of prewired dual speakers and a built-in amplifier,
in hardened plastic to take a beating and keep on playing. 
The recessed plug-ins cannot snap off and the 15 second automatic battery
shut-off will keep the 4 AA batteries fresh for many hours of playing time.
Plug in your Ipod, MP3 player, MP3 phone, Sony PSP, Nintendo DS or Laptop.
Use with your portable game player and immerse yourself in the game experience.
Skateboard, snowboard, bike, ski, jog, or do your favorite activity hands free and without plugs in your ears.
