The past week or two had the left earbud causing more excessive buzzing than it usually makes while occasionally dropping connection altogether then reconnecting by itself soon. Sometimes it'd stop the buzzing after shaking my head a little. While there's no obvious indicator it's on other than wearing it, the Samsung Wearables app indicates it's not connected, even when it's actively sitting in a plugged-in charging cradle and flipping closed then open after some time.

After hearing it softly buzz while not making a connection and the charger's inner light green when placing the clearly not full earbud in, it seems the battery is losing contact. Squeezing the earbuds from touch end to charging contact terminals causes it to turn on and operate as usual, for now. I assume it's only going to get worse and curious what could be done to permanently, or long-term, fix this.

I’m trying to decide if this is a mechanical issue or software issue.

The problem occurs across multiple devices, after unpairing/repairing, and with and without the Wear app. The software is up to date through the Wear app.

The bud is not visibly clogged, but is there a way to take off the metal sound screen for cleaning? The teardown video doesn’t show this.

I have found this video of the teardown and it shows how to get to the battery but it does not show specifics of how to replace it.

Would anyone else have points to follow or a video/manual of how this can be done please?

What kind of adhesive is used for this piece?

Thanks!

Though, the already very subtle electronic blips and constant noise on the left earbud has been exacerbated after reassembly. Only frequent chirps with nothing playing, quite noticeable at normal volumes alongside the constant buzz, more noticeable at lower earbud volume levels (noise stays the same volume), phone calls makes the noises louder, and Ambient Noise passthrough is now only somewhat usable as the electronic noises becomes very loud. This is only within the current first charge cycle as I've just done this today, but it's very annoying and all I can think of is to drain the battery (use till shutdown), pop open, and clean any exposed boards with IPA and a cotton swab; I was not diligent in not touching anything directly, as i was getting quickly frustrated and careless.

Side note: using 2 blue iFixit Pry Tools is significantly easier than the guide and other videos to open up the earbuds. They'll push against each other and apply equal force on each side of the earbud effectively.

I'm pretty sure this is because of the buildup in the tiny holes (which I assume are for the microphones) on each ear bud getting clogged with debris and gunk (maybe I broke the mic by inserting toothpicks in too far too many times) and that these have been drenched in water and I have not dried them fast enough with a heat gun.

I have used 99% Isopropyl Alcohol but nothing seems to get the left earbud's mic to work properly again.

Any idea on where to go from here? I have not decided to open them up but I have the tools to do so and that might be the only way.

Thanks for your time for reading this
