Today's planned activities:
1. Use a sacrificial pair of IEMs as matrixes, and try making some ear tips with Radians earplug mould and the DIY instructions on Make:

2. Some hopefully simple wire soldering: Fix a broken plug on my partner's phones and complete a couple other things.
3. Finalize the BOM for this winter's cabling projects and start ordering stuff. This time I'm going to experiment with finely-stranded silicone wire (do your cheaper IEMs have incredibly flexible cables with rubbery insulation? That's silicone wire), which ought to be kind of challenging to manage at the solder joints (all those fine strands). The intended result has more to do with ease of use for my purposes than with effects on audio quality. Although I might also get some silver teflon wire (so-called: It's silver-coated copper in teflon insulation) on the cheap to test my own skepticism regarding cable and sound quality.
One of the nice things about having a couple defunct pairs of UE universals lying around is that I've already got some donor cables as backup for everything else coming in. The basic plug and socket configuration is common for UE, JH, Heir, and a variety of other brands; the UE universals use a slightly different connector but that can be rectified quickly with a wirecutter and box knife. (The change is irreversable but the donors are not in a state to care any more.) So while there is a pair of full-size cans I'm rewiring because I find the existing cable of fine quality and poor ergonomics, all the cablemaking I'm doing for portable audio is primarily my own artsy-craftsy pursuit.
