just received the Qian 25 10th Anni, nice earbuds too.
superb value, for those who are interested in getting FAAEAL Iris 2.0 or Ancestor can forget about it, just buy the Qian 25 10th Anni. (for those who already bought FAAEAL Iris 2.0 can try to replace the stock foam with donut foam)

Qian 25 sounds best with donut foam, while NiceHCK YDX sounds best with normal full foam.

Qian 25 has better coherence across the frequencies, but lack of the treble sparkle that NiceHCK has.

worth for getting both (though i prefer NiceHCK YDX more), thanks again for the recommendations 👍🏻
