Yes, you can apply EQ in the WiiM app.Sorry for the basic nature of this question...I'm considering getting a pair of headphones (maybe Sennheiser 650 or HifiMan Sundara).
Would I be able to plug them directly into the Wiim aux out and drive the phones satisfactorily? Has anyone tried this? And would I be able to apply EQ using the Wiim app?
Regarding headphones direct connection... Some people did that and had said that quality was fine. Sundaras are rather easy to be driven.
I'm pretty sure not everyone will be satisfied with the sound quality of such connection. WiiM's DA conversion is not the best. Impedance of line out differs from the impedance of real headphone output you have in the headphone amplifiers.
