About the Galaxy Buds FE
Galaxy Buds FE are wireless earbuds which allow you to listen to music or answer
incoming calls after connecting them to your mobile device even while doing other
activities, such as working out.
Do not wear the earbuds in high-traffic areas, such as roads or crosswalks. Doing so
may result in accidents because of slowed reaction times.
