My left AirPods 1st gen stops all of sudden

well, hello everybody! My left AirPods stops all of sudden, the right one keeps playing tho..

I have tried all of these called fixes but nothing could bring any luck! Before you say the obvious I have to inform you that I am aware of battery problems and I don’t believe they would last forever but I kept a record of both AirPods and charging chase for battery drainage… so my question is very simple… do I have to toss them away and buy a new pair of AirPods Pro? Is there any other solution that could help me and bring me peace cause I swear the fact that I am in the middle of my workout and music stops… it’s awful! Thanks for the attention 😊
