My Motorola model S805 (studio monitor type) gives much better music sound quality (as it should) and even has a separate mini-plug cable for direct hook-up to the music source for use as standard wired headphones. However, I have found that my S9 does provide acceptable music quality for my needs when walking around. Recognizing that, I rip my music from CD's in ogg or 128-bps mp3 to save memory space for use with it, rather than in flac or 320-bps for use with the S805's.
