u18s deviates from u18t the same way z1r deviates from z5, if that makes sense. They become more harman-like, while not trying be harman-exact: they take away a bit of warmth from the mids. u18s is one of my all time favorite IEM, fwiw.How do you compare z1r to u18s they sound nothing alike? But i agree u18s doesn't sound like the usual 64 audio tuning imho.
I can imagine legend x being great for outdoor use. z1r for outdoor is a no for me though. Too heavy (which induces microphonics at the eartips) and bright. Never heard the mest mk2. Nonetheless, glad that they work for you!But he ranks the legend x highly. Also ranks the Z1R highly. Both of those iems are excellent for out door use. He also ranks mest mk2 higher which has the bone conduction driver. All those iems are excellent for outdoors imho as that's my primary use case.
Bggar and crinacle rank the evo about the same and they have different opinions and look for different things. They both love legend x.
I don't always agree with their rankings either.
I never heard the evo but i love the legend x. But Crinacle definitely has good recommendations for outdoors and i don't believe his recommendations are only good for indoor quiet usage.
