Quick one, I've read this whole thread and have seen a lot of comments about comfort that don't seem specific to this iem, anyone not accustomed to iems who suffers itchy ear canals or discomfort, my experience has been that it gets waaaaay better with continued usage. I don't produce a lot of wax and suffered with itchy ears a few years ago when I discovered iems, hadn't used ear buds for more than an hour or two mowing the lawn until I discovered iems and trying to use them for more than an hour or so caused me incredible bouts of itching, changing tip type didn't help, after persistent use of fairly standard tips I can now go all day with no real issues except the odd tickle which I would get anyway.
I learned a lot about my particular ears scuba diving, they despise any attempts to interfere with their natural balance, poking anything in them causes issues, trying to clean them makes things worse (this may be different for heavy wax producers) and any oils, unguents or ointments is asking for trouble! the main thing you need to do is use a tip thats immediately comfortable and stick it out as long as you can, Ive sold some incredible iems I wish I hadn't due to itching and discomfort that's now a serious non issue for me. Sound preference can be dealt with a little later on when your ears have stopped protesting at being penetrated, then you will be able to tip roll for the sound you prefer.
With regards to the sound of this particular iem, its great, occasionally I hear a disconnection between the sub and lower bass and the rest of the curve but its not often and forgivable for 50 notes! otherwise they tick more happy boxes than sad ones.
