throughout my journey of owning so many headphones and iems, I can say this, I used to hate listening to coldplay album XY as on everything I used to own that album used to sound like utter crap, until I bought my shure kse1500 and stax 007 mk2, this shows how marvellous the kse1500 is. Good luck enjoying that album on anything other than kse1500 or 007 mk2
i can literally confirm that kse1500 is a marvel, and i am surprised why it does not get more love here on headfi, it puts all iems and headphones except stax 007 mk2 to shame ( if you look at my inventory that includes every item listed there )
I have yet to find one headphone other than stax 007 mk2 that can me make enjoy the XY album, as for iems that i own/pwned forget about it only kse1500 has nailed it period
if anyone concerned it lacks bass, or needs any fix in any frequency I can say form my perspective it is dam perfectly tuned, that no eq what so ever is needed, and I listen to all genres
