Here are two stylish iPod speaker systems by Sony – SRS-GU10iP and ZS-S4iP – set for the today’s faceoff. To give you an overview first, the Sony SRS-GU10iP is a desktop model with an blasting output of 20 watts. It’s simply astounding with the Bass Reflex feature. On the other hand, Sony ZS-S4iP is a Boombox type system with an integrated CD player and an FM/AM radio tuner. It’s a cool accessory to carry on vacations. However, it disappoints on the output front, which is merely up to 2 watts. Take a look at their individual specifications and prices.
