I would assume that any linear switch would sound like that. It's just the sound of the keycap hitting the switch housing (bottom out) and has nothing to do with the switch mechanism itself.
On Cherry MX and Kailh clones of MX switches, the keycap does not impact anything. The slider inside the switch impacts the bottom switch casing, so it does have something to do with the switch design at least.
The sound is affected by how the switch is mounted, what material it is mounted to, how the plate is mounted (if present), the keyboard case design and material, the keycap material, the keycap thickness / shape, if orings are used, etc. So even one switch type can sound quite different in different keyboards.
To get to the point, I would say that Kailh Blacks will sound almost identical to MX Blacks in a similar keyboard design (since they're almost identical in design and materials), so if you want to know how they sound, look for MX Black sound samples in a similar keyboard design to the one you're interested in purchasing.
