Would love to see an actual disassembly guide for this one. Interested to see if it's even possible to do without damage

I have the similar issue too, speaker loosen, cause rattling noise. Need to tighten it with some strong glue , no experience to open the earpiece

Thanks for doing this, Hugo. I too have the rattle. It sounds like a speaker rattle, but then I realized I can shake the headphones and something inside is completely loose. For my pair it’s the left ear, so I see from Hugo’s photo there’s a battery and a speaker in the case. I find others are drilling a hole and injecting some epoxy. What I wanted to understand is whether the objective is to glue the speaker to the inside wall (against my bone) or to the outside wall (the side with the control switch). I guess I’ll just go for it, maybe all that matters is that it’s secured to the case. Also I see all the conformal coating, so I’m wondering how the speaker was secured in the first place and whether I should use a rigid epoxy or a rubbery RTV / silicone caulk adhesive.

Is there only one battery in the headphones? Our dogs chewed them up abs want to make sure they didn’t swallow a battery.

Thanks for sharing views of your unfortunate unplanned teardown, Hugo.
