Ambient and space music are two of my favourite genres. I find the KZ ZS7 very good here as it has a superb sub bass and creates excellent atmosphere. However I am currently testing the TRN V90 and it is shaping up really well. It has a similar sub bass but the treble is superior with its 30019 BAs which sound much more natural than the 30095 BAs. If detail is your thing, I would suggest the Tin T3 or TRI i4, and perhaps also the CCA C12 although that has a bit too much emphasis in the upper mids/lower treble, in which respect it resembles the ZS10 Pro. I hope this helps!
