My friend is a gamer & he said ew200 even better for gaming. It has smooth less bass make you don't feel tired when bombing effect or so much footstep at same time. But he said ea500lm better than ew200 about vocal. Sounds so smooth with R&B, ballad. If someone own ew200, he said better get em6l for upgrading.
My favorite budget IEM is the EW200 after I added 300 density mesh filters from the tuning kit and switched to Final Type E eartips. Simgot's dynamic drivers are extremely good. The only sub $100 single DD IEM that I have which sounds slightly better in terms of nuances in the texture of drums and bass instruments is the Kefine Delci. The Delci has very different tuning in comparison to either the EA500LM or the EW200. Hopefully you will review the Delci which is a direct upgrade for people who love the QKZ x HBB for its boosted bass and sub bass.
EA500LM for me personally but if you want something smoother with a bit more warmth or bass emphasis then the Xuan NV would be the better choice for you
