Well I can't say personally anything about any IEM or buds, sensitive ear and all that so no on-ear headphones or earbuds for longer than 10-20min. I'd imagine in a headphone thread people would have more experience with the ones that sit on your head rather than in-ear.
Nothing wrong with the se846's from what i've briefly read. If anything they've held up quite well to the competition. Decent bass and great soundstage for in-ears are a +1 in my book, even if i'll never be able to enjoy them as much as others.
Beyer's are a bit notorious for their brightness, not sure if that applies with ALL of their products though.
