My battery is really getting hot when charging

@gub155 yes, you can. It might have worked better if you would have told us exactly what model your Live is. Anyhow, since iFixit does not yet have a guide for this, use something like this video Batteries are readily available at many online stores.

While you work on your headphones, take lots of pictures. Once you are done with it, take those pictures and create a guide for iFixit. That will help the next person that has a device with the same issues as you do. It's easy and fun to create these guides. https://ifixit.com/Guide/new The iFixit community will appreciate this.
