I've already have senn 598 but not that satisfied with it. Ppl recommended me beyer 770dt pro but i went with the senn. Is it worth to get he beyer? or some other IEMs?

I've lowered down my budgets and decided to go on IEMs. right now im considering these few: HIFIMAN RE-400 , YAMAHA EP-100, TDK BA-200. are these any good?
