- Nice tight bass, smooth (not dull) mids, and clear highs. Very good sound stage.
- What a wonderful balance with a very present but controlled low end and perfect clarity without being shrill.
- It is very nicely balanced with good clean bass, smooth midrange, and satisfyingly bright highs (without being harsh at all). By the way, the bass is not overpowering at all: it's just natural. But on tracks with heavier bass, or when boosted with an EQ, the ZSTs handle it with aplomb.
