the bore opening on the stock biflanges are considered "narrow"??? everything else i have in my collection is narrower than that! the hybrid one included has a huge bore! that makes the entire sound very lean and helps with the treble and percieved airiness even more
i got the bright red, the silcone is not as pliable as the sony hybrids a bit stiffer, but not uncomfortable for me
their not as narrow as the sony hybrids, but not as wide as the biflanges (so far anyway, i find i switch back often but right now i'm happy with them) they seal well for me, and are dirt cheap (i paid like 6 cents including shipping, and it got to me in toronto in like 2 1/2 weeks from china) Can't complain
their in between the two in terms of sound, not as dark/warm as the sony hybrids (killing the upper treble extension) but not as lean and airy as the stock biflange
i feel its still lean but has enough weight for me =)
I meant the mini double flange (where the flanges are close to one another) and not the larger double flange, if that's what you mean. I know HiFiMan recommends those and they do sound good (and I can get a pretty good seal too) but I think larger bore tips just work a bit better. Those tips look good and inexpensive, and maybe similar to the stock hybrids that came with my GR07 - I ended up with a ton of left over tips from when I had my RE-ZERO, mostly from Meelectronics, that all fit the RE-400 perfectly. Most IEMs are prone to changes with different tips, so that's a relatively inexpensive way to passively tune the sound and comfort to your liking Man, I've tried so many different tips in my universal IEM journey lol. I think my next portable purchase is going to be cIEM and just get it over with...
