Mojo 2 FTW. Kudos to Chord I'm afraid i'm not the target audience. As a man with limited resources the price/performance ratio is not great. I'm happy with my Tempotec HD pro.
This is a review and detailed measurements of the Tempotec Sonata HD Pro. It is on kind loan from a member and costs US $54 on Amazon including Prime shipping. The Sonata HD Pro comes in the usual rectangular dongle size: The differentiation as you can barely see are the volume control...

66 mw 32 ohm. 300 ohm 14 mw. 66 Mw is not enough to drive a 23 ohm Drop Ether CX headphone I'm afraid. But that thing is out of my price range anyway.
Amirm uses one in his tests regularly. He has way more disposable income than me. I'm not jealous. He deserves every penny of it. Amirm is a GOD. (of science?)
I'm a nobody. I'm curently using a Sennheiser HD 560s. It sounds good without EQ. With EQ it will blow your mind. Thee sensitivity of the 560s is 111.91 dB/V SPL by the voltage and 104.00 dB/mW SPL by the power.
It's not really comparable because the Mojo 2 has its own power source. USB power depends on the device you're using. Announced in 2021, the USB PD Revision 3.1 specification is a major update to enable delivering up to 240W of power (28V, 36V, and 48V fixed voltages enable up to 140W, 180W and 240W power levels, respectively...)
over a USB-C cable. 240 WHAT?

What i'm trying to say is that you need to pay close attention to the specs of your equipment and make sure that it is capable of driving the thing you want to drive without $%$* with the frequency response and/or distortion. The truth will set you free.
