Well after hot melt was mentioned I looked it up and it turns out IPA is the exact solvent to use for it. There's videos of it being applied and almost instantly releasing the glue. I've tried it on the glue on my headset and it does soften it to some extent but there's no magic instant release so I'm not convinced it is hot melt glue. I suppose it's all academic now anyway as I've gone for the brute force approach.
