Pros deep, powerful with its size
Cons sometimes small volume
Summary First of all, this 5 stars comes from comparison: at roughly same price, same output Ws, around same size and weight (those docking system are like big brothers compare to this one or its clones)
Under those conditions, this product installed SRS, which made its sound quality much more better than other brands' choice (Can I say their name ? Victor, Audio-technica..... My wife and me spend couple songs in between these products indoors, and made the same conclusion -- this one rocks !!)
While made the comparison, with SONY M50, you need adjust its volume a little bit louder in advance, or you will find its sound seemede smaller than the others, but as soon as you set to same volume standard, their differece are very obvious.You can still adjust this speaker to satisfied loud level and do not need to worry sound broken !!
Anyway, according to my small field test, there is no rival on the same product lines
"Smooth Sound!"on by tingo25
Pros I bought these about a month ago. The sound is smooth and vocals and bass are clear and defined. Highs are directional to a degree but overall crisp. Three batteries lasts about 20 hours. I use hybrid batteries, they are weaker but cheep to own.
Cons I wish the grills offered a little better protection. Must set the on a smooth flat surface.
Summary Low price and great sound, runs on batteries.
