    Maybe try a bit of mild Flux, to help clean the wire, which should allow better wetting of the solder.
    I've been using WBT Silver Solder for years, mainly on copper wire (tinned & untinned), and IC chips.

    Can you please share to me a link of the product to see how it looks please ?

    sounds like your copper wire is "enamelled" copper wire.. usually more flux paste and longer soldering time with higher temperature helps a lot..

    To melt the "enamelled" of the copper wire, I make a melted solder ball attached to the iron tip and then dip the wire for some seconds into the solder ball until the "enamelled" melts.
    After that the wire is good to solder.

    Many thanks, I tried this and it just worked perfectly. I ordered (before trying this) a cu0.7 solding wire, so I will give a try to see if it helps too (for the fun).

    Thanks for sharing this useful tips, I will try your method next time :)

    Many thanks, I will give a look

    you're welcome,
    that's ok for soldering plugs pcbs etc. but when you solder that cable to the an earbud driver please prefer @Merlin-PT's method; since drivers don't like high temperatures and long soldering, it's more secure for them :wink:

    Hello, I forgot about this thread.

    Something I do these days when I re-assemble the bud, is to put a thin width of surgical tape over the body/cover gap rather than glue them together.
    I find it provides a more consistent air pressure seal. Easier than applying glue. And easier to take apart the buds again.
    It looks ugly until the foams go on. Then no one will know it's there.
    Works for me, and road-tested fine for past 2 years; never came apart.

    Do you mean during the laying of the grill (usually which contains the speaker) on the shells ? or once everything is in place ?
    (not sure on the picture as I don't know this shell :frowning2: )

    After you re-assemble everything together. The cover/grill and body usually snaps into place even without any glue, so just lay a thin strip of the surgical tape around the circumference and then work the sides of the tape down with you fingers. It was originally suppose to be a temporary thing, but it worked so well I put them on all the buds I assemble.

    It's a white E808+ shell.

    Ok now I see, thank you very much for clarifying :)
    I'll try that and report :)

    I don't think there should be any sonic improvements, unless it was leaking terribly at the cover/body gap in the first place.
    Main thing for me was, it was easier to assemble & disassemble the buds. It made correcting mistakes easier.
