Many thanks!In Alliexpress shop of E1DA you can select the usb cable which will be usefull for you (short C to C or OTG splitter for power bank)
or TRRS version of MMCX cable for headphines...
I took a short video during S/N pretest.Ambient temperature = 27C. As you can see, most of the units close to -123dbA(AVG probably 122.8dbA 3.4VRMS REF). Actually, I measured 175pcs but recollect that I can take an interesting video only in the end of test ))
@IVX Imho those editions could be explained a bit better as not all can understand the differences by comparing OTG, C-C, MMXC etc..In Alliexpress shop of E1DA you can select the usb cable which will be usefull for you (short C to C or OTG splitter for power bank)

BTW, one of 175pcs showed me 115/122dbA, and I replaced all that only I can suspect! ES9038Q2M, AD8397 on the left channel but finally, I found scratched 200ohm 0402 res.
That looks really ingenious. Wow!
This month I think.
