Smart glasses with stereo speakers feature a small speaker built into both temples. Since the sound is played separately for the left and right ear, it creates a so-called stereo effect. This means the sound feels more spatial, and the listener can better distinguish which side it is coming from. The speakers are positioned near the ears but do not cover or enter them, unlike headphones. As a result, the user can listen to music, podcasts, or take calls while remaining fully aware of their surroundings, such as traffic or a conversation with another person. This method of listening, known as "open-ear listening," provides an audio experience that does not isolate the wearer from the outside world.
