I’ve had it for a few months now and I have no complaints. Beats the hell out of all the other hi-res dongles I’ve bought or tried.

The issue with output impedance is that if the total voltage is divided between the 2 resistances. So if your headphones are 7ohm and the output is 2ohm about 20% of the output voltage is getting lost and not going to the headphones.

That being said iems are usually pretty sensitive so they don’t need a ton of voltage. You could most likely get by with your phone but a good dongle would probably be a noticeable step up.

I think this one is supposed to be good but I can’t vouch for it personally
