Wish it had the extended (1cm long) USB-C jack to fit IP68 style phones (ie Blackview BV9500 Pro). I've loads of issues finding the actual cables, the ones supplied with my phone are crappy :(
Can't see it metion a DAC so these may not work on phones that don't pass the analog signal to the USB-C port like pixel etc
iphones don't have a USB type-c port so it won't work at all. You need a lightning to 3.5mm adapter, either buy original (which cost a lot) or buy from Gearbest/Aliexpress/etc. and hope that it works. It seems some adapters work with firmware 10.2 or older so be careful.
i have bought one of this for iphone and it never worked. gearbest never replied so i have stop buying from them
Apologies, I must have clicked the same link twice as I saw the same price both times.
