Yea I was thinking Final E is old school, but when tried with Performer 5, it had pretty warm and nice bass resonance. Final E still can do good job to some good matching ones.
Just like Final E = Get Final E500 $20 which comes with full set of Final E,
Moondrop Spring Tip = Get Chu$19, it comes with full set of Spring Tips if separately bought $12.99
Also if you get Moondrop’s Stellaris, around $109. It comes with full set of Softwars UC (S, M, L). If separately bought it only has Sx2 or Mx2 or Lx2 for $19. Stellaris, is questionable one from Moondrop. Sounds like KZ’s ZS10 in terms of tuning. Can handle some acoustic genre pretty well, and Planar driver’s spec is very good.
My speculation is that KZ and Moondrop sent their product design to same ODM. ODM mistakenly put KZ’s Planar design as Moondrop Stellaris, and Moondrop’s Design as KZ PR1PRO. That makes sense.
KZ curve.
