Hum, better or equal to triple drivers SE535, thats a very audacious statement...can't compare the BRO to them as I never heard them, just own the SE430, from what I remember they were brighter, bass was tighter but less impactfull and round, they have more details and better layering but a smaller soundstage and overall more displeasant soundsignature (I sell them back cause I did not like how they sound kinda dry and fowards).
So, the BRO now. Soundstage is quite immense and have enough air to feel deep too, layering is okay, not extraordinary tough. We have a U shaped sound signature with great bass impact even if little warm it do not feel too loose or boomy, its heavy bass with great transparency that let the mids breath enough, wich is impressive for this price range, cause I like the vocal even if little dark they still feel lively as I can confirmright now listening to Elina Duni quartet, were drum is very heavy, bass player is hearable but not very detailed, piano have good impact and sound good even when the signer is there.
I would say the BRO have a rather laid back sound but with treble peak in highs region, so we got good micro details too, but very rarely they can sound a little harsh, like snare or cymbals, but more with treble heavy tracks or bright audio source, cause I will never say the BRO are too bright at all, or fowards sounding, just a push in upper mids and highs regions.
Compared to Tinaudio T2, they have a thicker bass but less detailed, a larger soundstage but less deep, less fowards and bright mids, and about same highs but T2 have better layering and clarity, little brighter as well.
Compared to Zhiyin Z5000, the BRO have a little smaller soundstage and feel less airy, it have less sub bass, feel little brighter but have less micro details and the mids are little more recessed.
I don't own the ZST, but I think that I read some people saying the Bro and ZST are similar...I prefer the BRO to the ZSR tough, wich I find little cold sounding even if soundstage is bigger.[/QUOT
