Left bud a lot quieter than right bud

[DanH1]

Hi,

I have recently realised my left bud is significantly quieter than the right one, I use the left one all the time and rarely use the right one but it's is about 90% quieter and even on full volume its so quiet unless you are sat in a silent room you can't hear it?

Same thing happened with my ear  buds, I  realised when I changed the left ear bud, that the sound wasnt the same.
