Introducing the latest in wireless innovation! 🎶 The Airbud Signature S680 is designed to fit your dynamic lifestyle, delivering powerful sound with every beat! #Audionic #Airbuds680 | Audionic - The Sound Master

When something breaks the sound barrier, it means it’s moving faster than the speed of sound (about 1,235 km/h or 767 mph at sea level). As it pushes through the air, it creates pressure waves that pile up in front of it—like a boat pushing a bow wave in water. At subsonic speeds, those waves move away faster than the object, but once the object outruns them, the waves compress into a single shock wave.
