AutoEQ on the mdr-zx110 was pretty awful, AmirEQ is better.
Imaging is like non existent, but the tonality is okay. Guitars and Bass sound dynamic, but the resolution suffers a lot,
due to this the bass punches or treble spikes often sound harsh.
For a little more money you can get the Tin T2s, with better resolution and stock tonality.
If you only want to pay 12€, then maybe look at the
Sony MH755.
For the price it's good, dynamic tonality, with punchy bass, surprisingly relatively great soundstage and open dynamic treble.
Tonality wise great job (with amir eq), but I would never own or recommend this headphone.
The Tin T2 eq'd do the same, but better.
Dac/Amp used: SMSL M500.
Music: Spotify and Daft Punk flacs.
