🎧 is the emoji for a pair of headphones. It is usually used to represent concepts related to audio, music, listening, etc. It can indicate that one is listening to music, the radio, audio books, etc., and can also be used to represent topics related to the headphones themselves, such as buying headphones, the styles of headphones, etc.
I like to use 🎧 when listening to music.
He wears 🎧 and immerses himself in his own world.
