My right earbud has stopped working for no reason, i did not drop them or get them wet. The left one works just fine and I have only had them for a few months. I tried tapping it and even taking off the white cover thingys and still no sound comes out of them. HELP PLEASE & THANKYOU

Did you ever find the solution to the left channel issue? I have the same problem with mine.

SOURCE: right earbud plays really soft.

Here is a tip for people attempting to fix the mesh (which, as it happens, works great when done carefully)

use a set of nail clippers or small tweezers to grab the edge of the mesh and pull the mesh away from the earbuds. If you disconnect it completely, do not get upset. Use the tweezers to carefully scrape both sides of the mesh (try not to be surprised at the gunk that comes off)

Once you scrape them clean, carefully try to re-attach the mesh. if you pulled it off entirely and cant get it back on, you may have to be careful about your earwax buildup on the unit, as it can get deeper inside the earbud now that the mesh isnt protecting the interior. Otherwise, pop the bud's cover back on and enjoy your music!

Ive done this fix on two sets of earbuds since discovering it. One set had what I thought was a non-functional right earbud, but it turned out that the mesh was blocked and interfering with the sound! It was working like new moments later and I was very happy to not have to purchase new ones.

They should come apart right where the metal meets the plastic, just below the buds themselves - be careful, one set like that I took apart were actually surface-mounted to the housing, there weren't any leads to repair...

You probably need to replace the stereo plug on the end that goes into the jack. Most of them are molded on unfortunately but it can be done with a new jack and some soldering skills. There have been lots of people with the same problem on this site so there are already some good explanations of how to do this on here.

i think ur headphone wires or its pin at end will be defective..
99%there is no chance of failures in speakers ..
try to replace ur headphone cable with new cable.
just solder the cable with speaker inline pins..
