Query: They were 9 bucks!

I bought a $800 car recently, with no soundsystem. I slapped these on the dash with some velcro, hooked up my ipod & I'm set! The sound quality is pretty great (for $9) & it's reasonably loud. The batteries have yet to go out & I got a cig lighter/charger for $3. I'm set!...I think they would be great at a desk as well.
