my left AirPod seems like the speaker is broken / won't work, i have tried all methods to fix this, it still makes fuzzy sound and when i run or walk outside and loud engine or motorbike go by it vibrates and buzzes loudly, sometimes it cuts out when i run also. It is fully charged and i have tried connecting it and disconnected in from bluetooth, reseting, etc.
