There was also this model, these were even cheaper ($2.95 ish), called KCKZ s72.

I found absolute Zero information about these IEMs.

As you can guess, this is also crap, but looking quite cool!

I can suggest QKZ AK6 as a cheap entry to IEMs if you like V shaped sound profile (which I don't).

Also, none of these come closer to Tangzu Waner SG, Moondrop Chu 2, or 7HZ Crinacle Zero 2, or even KZ Saga.
