I recently purchased a pair of Westone UM1s after I lost my Crossroads Quattros, took rather long to get used to the rather bass-deficient sound but I was quite happy with the overall sound signature. Switched from the comply tips to the Shure Olives, and found that that helped a bit. Then I was looking around and found this:
Well I thought it was rather interesting to try out, but I lacked the money to go to an audiologist to get a bunch of ear impressions (paying a third of the price of the earphones for an experiment? I'd rather not) and didn't have the balls to stuff epoxy in my ear like that madass in the second thread, due to me coming across forums which warned against stuffing anything into your ear whatsoever.
I coated them with nail polish and tried out the steps which the guy in the first link did, but then I discovered working with silicone and oil is a horribly messy process, not to mention not for someone impatient like me. Aside from getting almost uncured silicone in my right nozzle (which thankfully didn't impact the sound once I removed the waxguard, I was panicking like crap), removing half-cured silicone from a silicone mould turned out to be a lot harder and messier than I expected.
After a while I came across another thread in which the guy replaced his eartips with blu-tack and actually liked the sound:
so I decided heck-it-why-not and started trying to poke a hole through the impressions I had, and then dig out a bit of blu tack to form an outline of my UM1s and stuck it in. And the result would be:
Yeah green and pink don't really go, but I'm a guy and I couldn't get my hands on black nailpolish. ><
The earphones stick out a bit more now out of the ear though.
Sorry for the slightly blurry quality, phone cam with my left hand >< But it fits like actual customs.
Sound signature wise.. IT ACTUALLY WORKS. Or rather, I'm happier with the sound now. On the overall, the sound quality has lost a bit of its neutral quality for a more organic sound; the trebles are less well defined while the mids have lost a bit of their shine, imo. But on the other hand the trebles on the earphones were slightly too tinny for my liking in the first place, and the mids still have their strong bodied quality. The soundstage has also improved quite a bit, with instrument separation improving likewise. But the most significant impact would be on the bass response, which was previously quite inaudible but is now quite defined. And blu-tack eartips actually don't really look or feel like crap after being coated with a nice layer of nail polish (coat it with a clear layer first, then whatever you'd like to do with it). The isolation has actually improved, too. I thought the foamies were great at isolating sound, till I tried these on and went deaf to the outside world. (:
