The Sound Tube for Air 4 Pro from RayNeo is designed to increase the audio output with a 15 dB Dynamic Boost and reduce sound loss by up to 80%. The audio through the Sound Tubes is directional for your ears only, without bleeding out and disturbing others. It also keeps the open-air design of the Air 4 Pro intact, so you're always aware of your surroundings. You get a small and large pair of flexible Sound Tubes that slip onto the ear stems and over the audio outputs.
