Have had these a day now. Compared to my cheap Philips SHE9800 (£13.99) these are slightly less sensitive which is an issue, the treble has minimal presence, but seems better quality, but I can't get a good fit that stays well in the ear like the Philips do. The MMCX connectors are nice to have, I might retro-fit some to the Philips as I've repaired the cable about 6 times now and the heatshrunk parts are starting to stick out at funny angles! The cable is ok, too long to the split but with the buttons too near the earpiece, and the braiding doesn't seem to reduce the microphonics much.
These are my first that support Over-the-ear but I haven't found a tip+angle that makes this comfy yet, and the tonal difference while in the wrong place is quite large.
