5 Nearly Invisible Bluetooth Earbuds

Nearly Invisible Bluetooth Earbuds
Written by Louise Vee

Invisible Bluetooth earphones are a great way to make hands-free calls or listen to music on the go. Choose a discrete color with a long battery life for nearly unnoticeable listening while you work, study, or relax.

This style of earphone only includes a single earbud; the other ear is usually left open to promote awareness of your surroundings. Some Bluetooth earphones must be plugged into your computer to charge, while others use a magnetic charging dock for convenience. Look for an earbud with a quick charging time and a long battery life. Music always uses more battery than phone calls, so expect estimated battery lives to be shorter if you listen to tunes all day.

These five earphones all connect at reasonable distances, feature solid battery lives, and fit snugly within your ear. Consider whether you need features like multipoint connection, and choose a style and color that appeals to you.
