FiiO K3 • The Review Tour of FiiO K3 All-new Headphone Amplifier & USB-C DAC

Can anyone recommend a USB-C - USB-C cable that actually works with this? My K3 won’t power on with my Macbook, Macbook Pro, or PC using either an Apple cable or an Anker Powerline II...

I do appreciate the response and I’ve ordered one, but to be honest I probably wouldn’t have bought the DAC if I’d known that it required an additional, proprietary, unidirectional USB C-C cable (it’s also very short) from an overseas seller in order to work on a Macbook etc. without going through a USB type A-C adapter/hub....

One simple option I would have suggested, is to use an OTG

So type-C to OTG to the normal USB to Type-C cable (?)

I expect that the cable FiiO linked to is a basically a proprietary USB-C OTG cable, though my understanding is that OTG cables should not be necessary for USB-C to USB-C (FiiO initially suggested that a regular data+power cable should work earlier in the thread). USB-C DACs are pretty new, I wonder if there are other DACs with USB-C input that have this problem. Hopefully a firmware update can fix this since I assumed the DAC was broken when it woudn't power with a regular USB-C cable...

It typically should work with any Type-C cable. I mean, I conneced K3 with the really poor Mi Max 3 cable, as well as with a high-end USB 3.1 Type-C cable, and it worked with both. It doesn't seem to be picky on my end, but I'm going from normal sized USB to Type-C, not Type-C to Type-C

It doesn't work with any Type-C cable, as confirmed by another user. Type-A to Type-C does work but newer Macbooks are Type-C only. FWIW, I haven't seen any other DACs that have USB-C inputs...

Dear friend,

You could try this cable for help:

It doesn't have a USB-C input.

Got a question regarding the Lineout. Website says its 1.9V output from the 3.5mm lineout. Now i noticed the gain switch actually changes the line out power. So if you would use the K3 as a Dac would you put the volume to max +high gain or at low gain?
Thanks in advance!

Low gain. High gain also increases the noise floor, so if you are amping anyway, and the amp provides sufficient headroom, stick with low gain. Only use high if volume is an issue.

Buzzing noise when the knob is clicked off, and slight channel imbalance when knob is just clicked on with faint volume? There's also some static when turning the knob and little volume is added even though it's turned 4-5o'clock. I am driving 38ohm headphones at low gain. The product also didn't come with pads for the bottom.


UPDATE: Nvm, found the pads, they were so small and hidden in little box the cable came in.
