Dual audio on your Samsung devices lets you share the wealth, music-wise, by allowing you to simultaneously share audio to two earphones or speakers. You can also control the volume from an easy-to-access area so that both devices have the volume of audio you want.
Whether the earbuds you share your music with are among the best that support spatial audio or not, you'll find the helpful feature. Those days of giving your friend one of the earbuds are long gone.
