I liked the teardown of the Leaft Ear. For me this is an Engineering Marvel, because of the size of the earbud, FPCs are folded in perfect compact size in each earbud (which is an out of the box idea), for bridging all of the components such as the batteries, drivers of main PCBA, 3 mics and touch sensors for multifunctional inputs by users.
Also, One should need guts to proudly showing the components of the product, which is supposed to be kept as secret is a style of Nothing ®.
