Alright, these have the best midhighs and treble for a dynamic IEM I've tried so far, better than GR07 and EX1000. Smoother and more extended than both, yet as detailed and present. The only other dynamics I could think of that may be on par here are RE0s.
What spoils it is the bass, it's bloated and too slow. Covering the vent makes it less bloated, but it's a bit slower than it once was. I do prefer it with the mod just a bit still, but the mod only improves it a tiny bit.
I don't want to sound like an xba3 fanboy, but I will anyway.. I think you'd like them :)
Tips are nice, cable is AWFUL.
Yup. I tried using the mh1c's at the gym today (using the shirt clip, with the right driver around my neck), but while moving around, the left cable kept hitting my jaw and causing the driver to fall out. Also, there was some considerable microphonics. It seems that the cable being flat combined with it not being very flexible, results in the drivers coming out of the ears more often. I think the term "diabolical" has been used in reference in the past lol.
