^ After i got a set of these MH1Cs back for free, i was blown away by how similar they were to the FAD Vs as well as the Sony H3s in not just sonic presentation but capabilities as well. The only things that these MH1Cs were missing was some treble extension due to its smoothness, as well as a bit boomy in the bass regions and without the HD resolution, esp in the mids compared to the FAD Vs and the H3s, but they sound like they got about 80% of what the Vs and H3s offers give or take.
With the VSonic hybrid tips and stuffing the bass vent/port with some small pieces of earbud foam these MH1/Cs are SERIOUSLY much more clear with better resolution probably due to the stiffness of the VSonic tips which helps to "focus" the overall sound if you may. The foam helps to tame the boominess of the bass also attributes to a much better/ tighter low end. In totality the resolution of the mids seems to also have improved due such simple changes. WOW!!!
^ If anyone have the VSonic hybrid tips go try them on the Sony MH1/Cs......
... specifically those dark blue and green ones, the smaller ones don't work cuz it's too shallow.
Then alls you need to do if cut some tiny tiny pieces of earbud foam, or other types of foam and stuff the vents of these MH1/C with a sewing needle.
The foam vent stuffing mod is more clean looking than the tape mod methinks. :)
So pretty much this is your idea of a bit boomy then.
