Oooh nice! I don't have the TrueGrip, but I do have the heat-sensitive foamies and those work really well with the MT. They're a little broader on top than the ones you pictured, though, so I'm not sure how that plus the debris filter will mess with the sound signature. Keep in mind I have to remove those foamies in order for the charging contacts to properly align, but there's room enough on that shelf in between each bud at least.
Got them via eBay, but
pretty sure these are the same product. Really, REALLY comfortable. Zero pressure on the ear canal so far.
Yeah, something funky has been happening with my Right bud as well. Seems to follow whichever bud is the "dominant" one, in my case.
Not quite putting them on the bench; instead, just making them the dedicated SR25 TWS buds. I figure if they manage to remain stable on that DAP, chances are there's something at the phone level that's been screwing with me. Regarding the charging issue, maybe it would warrant a quick clean of the charging contacts? If that's what you want to do, there's two ways to accomplish it:
- Grab a Q-tip and some isopropyl alcohol (91% preferred, but 70% is fine). DO NOT use rubbing alcohol; it will leave a residue, which is the exact opposite of what we're looking for. Dab the head of the Q-tip into a capful of isopropyl alcohol and gently wipe the charging contacts (both in the case and on the device). Isopropyl alcohol, if properly compounded, should dry completely residue-free and leave your electrical contacts nice and sparkly. We used to do this to remove all sorts of nasties from printed circuit boards, especially leftover flux.
- If the idea of liquids next to your electronics is too much to handle, just grab a rubber eraser (like the one at the end of a No.2 pencil) and gently "erase" all of the metal contacts. Since this rubber is mildly abrasive, it should kind of "exfoliate" the surface of the metal, removing any oxidation. You will have to brush off whatever rubber is left over, but should end up with a pretty clean surface if you did it right.
In either regard, sounds like it's a contact issue. Maybe it's firmware and I'm off, but this might be worth messaging James about. Wouldn't hurt to ask when he plans to join the party, either. Said he was waiting on vendor verification a while ago; have to assume it'd be done by now.
