I'll get back to you on that. They are out on loan at the moment.
But they are hands down the best KZ for bass, and I agree with the description of "Lord Bass" haha.
I have no idea why KZ revised it and came out with a 2nd revision of the ZS1 (not the ZS2, but rather ZS1 v2). I think it was strictly a cost thing, because the v1 had a crossover and brass rings in each earpiece, which doesn't sound like a lot but at the time the most expensive KZ was like $9-$10, so trimming $2-3 worth of extra cost multiplied by tens of thousands of units can be financially justified by bean counters to the higher ups.
I have the ZS1 v2 (identical to the ZS1 v1 minus the crossovers and brass ring), and the v1 is much better. The ZS1 v2 sounds exactly like the ZS2 to me, so perhaps they were using the ZS1 v2 as a beta test for the ZS2 (really just blue shells are the only difference as far as I've determined upon examination of the guts).
I wish I could buy a crate of ZS1 v1 from some dusty warehouse back room! I'd be set until I die LOL
Is there any IEM that you've heard that is comparable to the ZS1(i)?
