UR22C with low impedance headphones?

Hi - I want to buy the UR22C for my girlfriend, but I’m not sure about the headphone output…

She has ATH M50X headphones, which are 38 ohm impedance. But I’ve heard that high impedance headphones are recommended (thanks to Julian Krause on Youtube!). Otherwise the bass response will not be flat, making mixing unrealistic.

If so, I hope she can use the headphone output on an amp connected to the main outputs. I just want to check - do the main outputs carry the same signal as the headphone out?

Thanks for any advice!

If the headphone sounds good than it’s ok, no matter what the impedance is…
ATH M50X has enough bass for monitoring work, these where my go to headphones for years

If the headphone sounds good than it’s ok

I agree, but what IS good? I find these cans have too much bass when using my old Phonic desk, so it’s hard to get a good mix with them. My goal is a flat response, so the mix doesn’t end up lacking bottom end.

But they sound great through my old Denon hifi amp, I guess because the output has lower impedance. I think she might end up using the amp for monitoring.


an impedance difference doesn’t change the general sound of a headphone that much…
and btw no headphones are flat…

if you want real flat (or very close to flat) headphones then you should use Sonarworks Reference

A much better solution, if it’s practical for her.
And yes, possibly it could be a load problem with the phonic desk (out impedance too high) or the output has an eq on it?
Anyway, to get flat response headphone listening you will need some dsp correction as @st10ss says, but if you want the flattest possible witout dsp I would suggest the Sennheiser HD650 or 660, those cans are somewhat rolled off in the low bass area but are imho really easy to learn to mix on.

Yes they do:)

Excellent, thanks! I’ll order the interface next week & see how it sounds.

Look at the graph though, it’s not a huge bass boost (iirc about 1dB) and you will learn to mix with that in no time provided you reference your mixes in other systems.

That’s good to know. The graph looks dramatic - but I don’t really understand it. Hearing it should tell all.
