I just got these, not here. They have a little brightness but not fatiguing and very, very detailed. Bass has impact but very controlled and really good sound stage.
I used XL spinfits and have no issue with fit, actually pretty comfortable as they are small. Note: I'm also using the tanchjim upgraded cable. If you can't get that try get the gray Linsoul cable on Amazon if you want something a bit better.
It beats more expensive options and overall I am very Impressed!
Would love to see what Tanchjim could do with hybrid driver configurations.
