Open-ear Bluetooth headphones are wireless audio devices designed to rest outside or just in front of the ear canal, allowing users to listen to music, calls, or other audio while remaining aware of their surroundings. Unlike traditional earbuds that block the ear canal, open-ear designs use technologies such as air conduction or bone conduction to deliver sound without fully covering the ears. They are popular for outdoor activities, commuting, and sports because they provide greater situational awareness, improved comfort during long use, and a safer listening experience in environments where hearing ambient sounds is important.
