I have the KZ ZS10 and AS10 models but I wanted a cheaper kit for training and outdoor use. These ZSN Pros are about 75% better at half the price. The bass is good and clear, the mids are clear. The highs can be a bit harsh for some female voices, but overall the tonal balance is very good. Build quality appears to be the same, if not the same, as the more expensive KZ. I think they will work fine as "active" IEMs for my use case.
