On tracks with powerful sub-bass content, like The Knife's "Silent Shout," the 99 Classics deliver a perfect balance of bass depth and high frequency definition. The lows on this track sound truly powerful-there's definitely some boosting in the bass department, but it never overwhelms the mix.
Excellent audio performance with articulate highs and ideal bass response; Comfortable fit; Lots of accessories, including detachable cables with inline remote controls
Expensive; Bulky design not necessarily ideal for mobile use
