You want BIFL? Get a good set of traditional wired headphones with a Bluetooth adapter/amplifier. Maybe a grado sr80x at $125 https://4ourears.com/products/sr80x?variant=39583367200816 And a Bluetooth thing like this for less than $20: https://www.1mii.com/product-item/ml100/

The cans will last forever (the parts like foam are replaceable). The Bluetooth bit will last as long as something with a lipo battery can.
