Only have the originally supplied and the balanced here so far. The balanced sounds better for headphones.

Aliexpress.Did you buy these from Hifiman's website or Aliexpress?
Just wanted to share my discovery. Apart from Hifiman amp cards, i have tried other oem cards as well. Tried Ufeel MK3 and Honor 3. Can safely say the honor 3, is much better than hifiman's own balanced card. Honor 3 is the purple card shown in Aliexpress store. Wayzr and way-zr2 are on their way. Will update once i received them.

a balanced card has a non-zero output impedance, so the sound is very bad on multi-driver armature headphones with a non-linear impedance, but on dynamic headphones it’s a completely different story

My bad and you’re right. Many of the amp cards will not have zero output impedance. And BA drivers based iems will suffer the most. FWIW, i am using SoundRhyme SR8 (14BA) with 4.4 plug. Compared to balanced card, this card (honor3) really have minimum background noise.please indicate the model of headphones on which you came to such conclusions
