"the best portable music system out there."4.5 starson by lbhajan
Pros: clean, crisp, clear sound at all volume level. absolutely no distortion
Cons: none except there is no am fm radio built in, little pricey but worth the money
Summary: got this for christmas and am totally impressed with the sound. makes me wanna listen to all my music all over again on this system. i don't think separate base and treble controls are necessary, the sound is automatically blended perfectly at all volume levels. i highly recommend this product, you won't be disappointed. bottom line, you get what you pay for.
