Need some advice from pros here. I bought a Baseus usbc adapter to pair with KZ zst for my Samsung S23. The usbc end of the adapter started heating up after a while. I tested it with Sennheiser headset with a higher impedance and no prob. Is zst so difficult to drive? I never had this issue when using on Huawei phone
interesting, usually if dac runs hot, then its hot with whatever you plug to. if runs cool then the same as well.
i have a cool type-c dac/amp thats plugged to pc almost permanently, and a dac that runs warm even when idle so i unplug when not in use.
nothing to do with the dac chip, more with how the whole thing is implemented. 1 thing that is consistent from my experience and general logic is warm/hot ones drain battery faster
current cheap disposable dongle i am using the VE abigail 4.4 (runs cool, sounds decent).
had the zooaux 3.5 (the first not bad 'cheap' dongle from early days), garbage ugreen dongle with PD port, no idea if real/fake samsung 3.5 dongle, some atz dongle which had hiss.
anything 'audibly better' you would be looking at the gum stick size dongle dacs, but can expect most of them to drain your phone faster although there are those reviewed to be efficient like the DC03 Pro (not used that before).
