Shure - KSE1200

Shure KSE1500 is 11 years old this year, still the most resolving IEM if you can call it an IEM, 2.5 years later came the KSE1200 which sounds same just without DAC and EQ included for less money

Shure KSE1200/1500 if you consider that an IEM, other than that 64Audio Volur sounds the best all around for me but I'd probably get something that sounds a bit worse to my ears but is a CIEM like A18s or A18t, if you are spending that kind of money you should be looking into CIEMs imo, good CIEMs start at $399 these days

As an owner of a utopia, a lcd5, and iems like kse1200, u12, and having heard the he1 I disagree. Headphones can still imitate this better as the drivers in some are distanced and angled somewhat like speakers. Kse1200 with some eq is the best resolution I've heard, id say even surpassing in some parts the he1, but the he1 again is just more real. Out ofnthe ones I own the lcd5 is the whole package, and the closest with some EQ to my mastering system with Lipinski speakers. But again, even these headphones are not convenient, as they still require being in a quiet room, and are heavy and leak sound, whereas iems are convenient. Shure kse1200 are what I use the most.
