Pro Can function as Bluetooth or wired headphones
You can continue using these headphones even when the battery runs out. Aside from Bluetooth connectivity, these also come with a USB Type C to 3.5mm cable, so these can be used as wired headphones. You won’t get active noise cancelling without battery power though.
