Chosen Solution

I have a Jabra Bluetooth Sport Pulse whit audio only in the right ear and none from the left although the heart rate monitor witch is in the left ear works OK? Can anyone advise how to tear down and repair Regards, Matt

Solution:

  • Remove earbud rubber cover.
  • Remove the small silver metal screen from ear bud piece. (lightly glued on)
  • Remove thin black cover from ear hole.
  • Remove stuffing/foam from inside ear bud canal with a needle or pin. Only replaced the small silver metal screen when putting it back together as it reduced the sound with even the small black film being replaced so I kept it out. This work around increased the sound to normal levels and they work like new again. This is not an amazing solution as you lose the level of sweat protection that it provides which i’m ok with because I don’t sweat heavily from my ears thankfully. Hope this helps.

Idk just buy a new one

Did you sleep with them plugged in? I had a similar issue with earbuds and it turned out to be earwax clogging the small speaker opening. I carefully removed the metallic mesh and got both sides audible again. Can’t say I would recommend everyone doing this if they are not sure / don’t sleep with earbuds plugged in though…

I did what they said above, removed the metal mesh and cleaned it with some isopropyl alcohol, sound is back and loud. Mind the rubber inside though, hope it doesn’t damage the sweat proof protection.

I removed the foil and the black cover. Then I just gently loosened the foam/stuffing inside but didn’t remove it. Put the two covers back on and the sound is back to normal. Dont know whether it’s the internal foam/stuffing stuff that’s just gotten lodged up against the diaphragm or something and so muffled the sound. Anyway now works

It frikken worked… my left speaker hasn’t worked properly in like forever… I couldn’t take it anymore and found myself here… all I did was remove the little white foam and boom. Full volume! Thanks for the advice. I was resigned to getting new headphones… these will do until they don’t! Cheers from South Africa
