So I've spent a few days with the Sony MH755, and I can definitely say that the hype is justified. The price these sell for is mind blowing. The short J cable annoying, but I haven't decided what I'm going to do with it yet. I know some will be converting theirs to MMCX, but something just feels wrong with doing that, as the mmcx jacks cost as much as the whole IEM lol. I might just shorten the longer side and pair it with my Xiaomi bluetooth adapter. Or maybe just recable it with a nice braided cable. Not sure yet. I did remove the foam plug that was stuffed down inside the nozzle. It sounds even better now - cleaner and crisper low end, and more clarity across the board. I also tried swapping the black nylon nozzle screens for stainless ones, but it made the treble too bright and grainy. So the black nylon filters are definitely the way to go on these. I'll have to keep that in mind if I transplant the drivers into different shells. I like the stock eartips too. They're unique among all my other tips, and really comfy. Well done Sony!
