Was thinking I finally receive my must waited ****, but well, its piezo too, its the NiceHCK N3!!
And its sure unique sounding....remind me more of being surround by vintage planar as I have...the Magnepan MG2A but plus a SUB! It really have great deepness to the sound and some crazy imaging too....man, for me its a keeper because its so unique..need more listen but this typeof sound experience cannot beeven achieve with 4-5-6 BA's im pretty sure. Its not at all like2 dynamic neither, the dynamic in there is something special as well. Hum, as said, soundstage is out of this world. Treble is different from what im use to, would say slightly bright but not real hurting hissing....metallic? No...''piezoic'' more likely. And yeah, its detailed...
I think I love them, its not your normal chifi iem for sure.
And at 55ohm they need power to shine no doubt about it, sound dull out of my Xduoo X3II.
Will share more impressions.
And pics?
