Looking for a replacement charger for my Bluetooth headphones

Hey, I could really use some help tracking down a Bluetooth charger for the headset in this photo. My old one is pretty ancient—probably 8 or 9 years old now. It’s an old Apple model.

This is the spot where the charger goes.

Could you please try uploading a smaller photo? It would make it way easier for me to actually help you out...

My bad, fixed it.

If we actually knew the model of those headphones, this might be a lot easier...
