Which are top Tier 1/2 in your opinion?
Keep in mind that Tier 1 should mean "the whole package", not something like: "yes, it has the best mids/highs I've ever heard on a headphone, but it is bass light". It has to have everything. So, IMHO, if is bass light, then it shouldn't be no.1 no matter how good the mids/highs are. If it has harsh highs or too much mids, again, not no.1.
For example, SHE3800 deliver enough bass impact to compensate the fact that they do not seal like in-ear, or over-ear headphones. You're outside walking, and you can still feel that impact. They won't hit like a sealed over-ear, but you don't feel the need for it to do that.They do not have enhanced highs, not recessed mids. This should be the definition of balanced.
Yes, on some rock music i could say that SHE3800 doesn't sound detailed enough/a bit muddy/not enough highs.But I'll take this trade-off against having to endure that piercing sound of Mrice E100.
