Thanks folk. How do these compare to ue900s? It looks like I might be able to pick them up at 50-70% of the price of other contenders. Granted, they wouldn’t be brand new, but it’s still a huge saving. I’ve been quite happy with how they sound to be honest, but not sure if I’m missing...

Many thanks! I will look them up, although looks like it might be a trouble getting them in the UK. Folk wise, it's guitars, banjo, bass, cello and what not! As someone said, let me paraphrase, The Devil Makes Three is like 3 concerts in one - so there's a bit of everything thrown in there...

I am looking to buy a new set of IEMs. Budget - at most £300, but fairly flexible here. Happy to spend less! Source/Amp - various laptops and iPhone XS. No amp and I would prefer keeping it that way. How the gear will be used - mainly office, so passive noise isolation is quite appreciated...
