potentially substantial breakthrough. needs testing. again.
i wasn't getting any grit on the bottom end - i've explained this before, that nice boom, the dynamics. sounded like it was through a limiter.
so, i swapped the other headphones in and, while they sounded noticeably worse, i was at least getting the dynamics. definitely headphones.
now, these headphones both say LCH on them. i guess it was a factory error. but, what i did was swap sides, and i seem to have got the boom back.
i'm hoping that's the last fix. just let me get through testing.
if that's it, it's probably a contact issue - the cord wasn't connecting right on one or both sides. that could have happened when i took them apart to clean them, and just put them back together without thinking about it.
