I know people have had a falling out with the recent Smabat earbuds for their tuning (or lack thereof) in the 3k region. I visited their English website to see what was going on with their crowdfunding of their wireless buds, what they are now calling the S2 Pro. Looks like they've made some design changes in their latest iteration (3rd update version) vs earlier versions. The 2 new major changes are beryllium driver (only for crowdfunding purchasers) and switch from Realtek to Qualcomm 3040AD chip. So Bluetooth 5.2 with APTX(AD) lossless (as long as your source has the same codec). According to their latest S2 Pro info, the beryllium driver is supposed to provide "more detailed non-sharp treble".Smabat has a new TWS apparently.
Called the S2.
Case looks nice, but not sure if the ergonomics will work, it looks like it might pivot out of the ears?
Also the 3 kHz Smabat house spike might still be there haha.

Anyway, for those interested there's more info (than the 2 pictures I posted) at their English crowdfunding product page:
