Advice! Simgot EW300 DSP or Moondrop May DSP?

I'm a newbie, and I hear that the DSPs are basically "plug and play", no need for like extra DACs and Cables and stuffs, so yeah cost-efficient?

Though I have no Idea on what to pick, they're both priced similarly

Hmm, I like punchy bass, and highlighted vocals and instrument, I guess "balanced" tonal?

I don't like sharp trebles (Tangzu wan'er, KZ EDX)

I mainly listen to JPOP and KPOP, and some bits of country I guess
