Why won’t my backbeat go 3 turn on?

I know that this is listed under backbeat fit but I didn’t see the option to choose the backbeat go 3 which is what I am having difficulties with. It will still charge and when I connect it to the charger, it shows that it has a full battery. No buttons are stuck, and I know that it hasn’t been exposed to any type of water damage. When I try to hold the power button to turn it on, the headphones simply won’t turn on. Any ideas?
