pls help, my left beats solo earbud doesn't have any sound coming out.

i tried reseting my earbuds twice and that didn't work. it says the left one is at 100% but i don't hear anything from that earbud when i use it. i tried disconnecting it from my phone and that didn't work either. it's not damaged or anything cuz i had these for two weeks and i didn't damage them and it's clean. it was working just fine earlier until like 3 hours ago. please help
