FreeTrack LED Mount (3 and 4 Point Versions)
thingiverse
Those are two variants for a Freetrack LED Mount, designed specifically for Headphones with two 5mm Archwires to attach to - in my case, steelseries. You could also simply glue it to another headphone or modify the Baseplates to fit your needs. This design uses three or four standard Red LEDs and an M3 Screw to keep everything secure. To power it over the 5V of USB, you'll need a resistor with a resistance value of 100 Ohms or less. I use this tool to calculate the perfect resistor values: https://www.kitronik.co.uk/blog/led-resistor-value-calculator.
