WM-BF22 Headphones
The Sony WM-BF22 headphones has a 80s feel to them with more mid-range to the sound. It produces a unique sound, which would be hard to find these days.
Mute Switch
This is an in-line mute switch, which allows the user to reduce the sound level, without having to remove the headphones.
Foam Pads
The original foam pads had disintegrated; however, I managed to find these ones from a cheap headphone bought from a thrift store.
