Gear I used:
Sinar 4x5 view camera with 22MP medium format back and 90mm f 5.6 lens
3x studio strobes with standard reflectors and 8° grids that illuminate the ear-pieces
1x studio strobe with standard reflector above the subject that lights the headband and the glossy white surface below the headphones
1x studio strobe with standard reflector behind a diffusion frame, that I used as a background
