When i received my einsear i remember i posting something like "they don't sound like any iem's i have" the mids are closest do my earbuds. That being Said, i Just put both T2 and was positively impressed. In terms of mids, they are close to the tin t2 in terms of volume, The tin T2 have a little bit more definition and less volume in the Bass, more texture, more details and texture on the lower frequencies. also overrall Excels in imaging, tone. But the einsear is i think the best mid forward iem under 10$. They are a true gem.
The KZ ate are mid forward, but lacks Clarity, the einsear don't.
I don't see einsear being Warmer.
About hm7, i remember them being close to zircon with less sub bass. The zircon is being kinda bashed these days. I remember liking them but my ear changed since them, i almost never use my memt X5 that i buy to substitute them, for example... Go for edr2. I never heard ed9.
