Glad your second pair suits you. Mine have been flawless thus far. No issue with the headphone band either (as some have apparently encountered).
I do not really understand the mid issue that some people are referring to. The vocals* are so well emphasized with those headphones (listening to Lord Baker by Sinead O'Connor (feat. Christy Moore), it is just a joy), they totally destroy the HE-500 in that department (some believe they have some of the best mids). One non-negligible aspect of the Elear, they are not fatiguing at all...more important (at least for me), they are so dynamic and fun at the same time. I do not know many headphones with that type of sound signature. I am sure they are better headphones out there (probably not at that price range though), but I must say I have been very satisfied thus far, and bear in mind I am just driving them with the Matrix M stage HPA2.
Also, the 4 m cable does not bother me at all...perfect for sitting on my coach while reading a book, and staying away from the computer
* No way they sound recessed
