I have an old pair of Beats Executive WIRED headphone that I bought second hand. The wire is NOT detachable at all. I’m not sure if they are strictly powered by plugging into a wall with adapter or do they have batteries inside?.If so, how do you open the battery compartment to replace the battery.
Welcome to Apple Support Communities 2ndhndrose,
We'd be happy to help. Based on the photos, it looks like you have a paired of Wired Beats. These would not require any type of charging. You would just need to plug them into the headphone port on your device or use the 3.5mm to lighting adapter to connect them to a lighting port on a later model iPhone.
Hope that helps!
