FWIW, I gave Brahms' German Requiem a critical listen last night (the 2009 Berlin RSO / Marek Janowski recording) and the Ostry KC06 did a wonderful job. Tonality / timbre, dynamics, intelligibility of lyrics (pretty tough with choral music) and soundstage / positioning felt all very lifelike and top notch.
Mind you, I'm used to listen with top-tier IEMs like the UERM, K3003 and FI-BA-SS on a regular basis. And yes, the $60 KC06 do fall a bit short in comparison, but not at all woefully so.
(Couldn't find Janowsky on YouTube, so this is DRSO / Blomstedt, also a great performance)
