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 think this mod is a good idea. Tape the vent and then poke a tiny hole with a needle, it's close to fully closing the vent, but it has small differences.
Tips are nice, cable is AWFUL.
