KZ ZS10 is in the house!!
Looks really nice, but the workmanship could be better. The BAs on the ride side is a little bit slanted.
I straight away switched to foam tips and tried it on with the upgrade cable. The foam tips is a little bit longer than the stock tips so it provides a good seal, no problem. Surprisingly the iems are not as huge as I thought, and due to the gentler contours, it's a much comfortable fit compared to my zs6. In fact, it's a very comfortable fit so far. The right side did exhibit a bit of a driver flex but hopefully it won't be a huge issue.
Now sound wise, it's pretty damn impressive to me. Comparing to my modified zs6 (slater's washer mod and ba mod), it has a very similar sound signature right out of the box. My zs6 has a little bit more punchier bass however. Hopefully the zs10 bass would improve after a few hours of burn in . Speaking of bass, it's definitely there. Even the sub bass rumble is strong. I'm not familiar with terms like "treble roll off" so I can't be of a huge help here, but all I can say is I'm really satisfied with it, so far. Listening to Low by Mura Masa kinda hurt my ears with the zs6 even after the mod, but not so much with the zs10. Not much of a difference in terms of soundstage. Separation is a little better. Female vocals (AURORA) sounds good to me, although I'm sure there are iems that sounds better.
Overall, it's a winner to me. Granted, I'm not an extreme audiophile by any means. My past/current iems include Carbo Basso, KZ ZS6, Tennmak Pro, Alpha and Delta AD01 (all of them leans towards being bass heavy). With such a similar sound signature to my modified zs6, I do feel like I'm wasting my money a little bit. But the tame trebles makes me feel a little better bout my purchase hahaha. The zs10 will definitely be my main driver for now. One day I may do the washer mod just for kicks. The nozzle diameter is a little bit smaller than the zs6 so the washer can't be inserted in but it does sit flushed on top.

Edit: On a second listen to both my zs6 and the zs10, the zs10 has way better mids to me.
