Query: In no way was I disappointed by the CX475- the sound quality is excellent, and although it touts bass-driven sound as a major feature, it isn't overwhelming, and it plays the whole spectrum of sound crisply and without distortion (a previous reviewer mentioned that live recordings weren't as natural-sounding as they could be, but I haven't observed any problems so far).
