Block the holes in the back, use a Comply tip, put a damper in the front, like a microfiber cloth with a pinhole or a foam plug: do any of these reversible mods flatten the response? You might be able to get it to sound better than a real IE800, at least on paper.

DeleteCheck the link above; blocked the vents, used the Comply T-500 and applied DF curve. Not that good as I expected.
Also you can check the posting above, [7. Vent Blocked ] and [8. Comply Foam Tip ].
DeleteOh well, we tried. The other mods I can think of aren't exactly reversible: drilling a front vent in the IEM itself or putting a microscopic hole in the tip. Also reducing the volume of the rear chamber behind the diaphragm by partially filling it with resin. Rin Choi did something like this with the Sony MH1.
ReplyDeleteMaybe a porous foam tip like Comply sport foam (S500) will work like a front vent. Anyway, thanks for investigating. Even if the results aren't perfect, they're still interesting.
That mod sounds very interesting, but this pair is not mine so I can't do a irreversible mod. I'll try that if I get a chance!
