If you're travelling at over mach 1, the sound from normal headphones would stay behind you. Those headphobes send sound not over physical waves, but electromagnetic ones, which let your music keep up with you.

I can confirm from firsthand experience that this is in fact what it looks like. The speed of sound changes with air temperature, humidity, and even air quality. Neither humidity nor air quality make enough of a difference. The speed of sound increases by 0.6 meters per second (m/s) for every degree-Celsius (°C) increase in temperature. Since the speed of sound is about 331.5 m/s at 0 °C, we can use these headphones to override the speed of sound at a given temperature of fairly comfortable, but slightly different indoor temperatures.
