Fixing buzzing H19txt bluetooth earpiece

After a year or so of using my H19txt, it started buzzing like something was on the speaker. I thought the speaker may have either been torn, or my ear hair was poking into the speaker.

After a little testing, I determined that my ear hair was definitely not poking into the speaker. So I decided to peel off the speaker grille. There wasn't much to lose at this point if I broke it. Luckily, it was attached with foam tape. Here's a picture of the earpiece with the grille removed.

You can see the black double-sided foam tape on the back of the speaker grille. There is a bunch of pocket lint, skin cells, and maybe even some ear wax built up on the screen over the speaker. Since I had a microscope handy, I took a picture of it.

After a little cleaning, the screen looks better.

Amazingly, after pressing the grille back on, the buzzing sound was gone.

I also went through the menu and turned off the voice interface. (To get to the menu, hold the call button down as you open the flip.) So now when I turn it on, it just beeps instead of saying "Phone one connected . . . More than eight hours of talk time." If I get a call and it's in my pocket, I can open the flip and put it on my ear and start talking sooner instead of waiting for it to get done saying "phone one connected".
