Sorry mate, can't help! I ended up waiting for the Whizzer TP1 to come out and so far enjoying them pretty much tbh; they fit nice even tho they look a bit big, they look great, and sound has been above what i was expecting for a 60-80$ TWS IEM. One gripe would be the chinese voice prompts but I don't use the voice prompts and it says the name of the contact calling me / the number calling me in english - don't ask me how, i have no idea how - so I'm good with that. And also since I'm 6'4 and bulky as fuck, I tend to sometimes have the bluetooth stutter a bit, but that has happened with both airpods, sabbat e12 and galaxy buds with me, the TP1s are actually better that the other 100$-150$ TWS I've tried. And it's my honest opinion; not trying to sell them out.
