Why does my iPhone SE with earbuds randomly activate Siri, start and stop music, and speed up audio?

I use my earbuds that came with my iPhone SE a lot. I constantly watch YouTube and then all of a sudden, Siri answers as if I called her. But I didn’t. Sometimes music on my phone plays. Sometimes the video starts speeding up a lot and the audio gets all messed up. Even my videos just randomly pause and play. But it’s not only YouTube. It’s all of my apps that have audio. Sometimes the audio doesn’t work while other times, my personal music plays. This has only happened to me while using my earbuds. When I don’t have my earbuds plugged in, it’s fine. Everything works perfectly. My theory, I broke my earbuds. That little rubber covering at the end of the wire leading to the plastic plug thing broke a while ago. It started to come off so I let it. But could this be the cause? Maybe it’s making my earbuds more sensitive? I don’t know. I want to avoid getting new earbuds because I really like my current ones and I’m honestly kind of broke. Any way I can either fix my earbuds or find another cause to my problem to fix?
