My take on the KZ ZS10 PROs
I actually purchased these IEMs from a different source. I tend to agree with most of the reviews that I’ve read on these monitors. They are an exceptional deal if you want a crisp, clear, but definitely V-shaped sound. The bass is deep and punchy. They generally have more of a sub bass emphasis than mid bass. They don’t sound muddy or boomy, though of course the transient speed isn’t like that of BAs. I personally prefer dynamic drivers for bass. I think most bassheads would like these IEMs. The mids are recessed vs the highs and lows. They’re smooth and clean, but nothing particularly special. I think the highs are well balanced, quite extended, and clear, but not harsh or sibilant.
The fit and finish is exceptional for the price point. They are very comfortable, and I have no problem wearing them for a few hours at a time. The isolation is average. I found the supplied tips to fit well. I actually like the cable a lot, and don’t mind the absence of a cinch.
In comparison to the TFZ No.3, I find the highs smoother on the No.3s. The mids on the No.3s are much nicer. They are more realistic sounding, are much more balanced with the lows and highs, and make vocals sound much sweeter. I do think I like the bass on the ZS 10 PROs maybe a little more, with the sub bass tuning. The No.3s sound warmer overall. Are the No.3s worth twice the price? I think so, but the ZS10s are still nice to have for variation. If you don’t like much bass in the mix, and want a more neutral sounding IEM, I wholeheartedly recommend the Tin Hifi T2s (I don’t own the T3s, so I can’t comment on them.). If you desire to use your IEMs for stage performance, I think the No.3s would be the best of these three monitors, but perhaps with foam tips, for better isolation.
