Open Ear Earbuds - Open-ear design for situational awareness: The clip-on earbuds do not enter the ear canal and sit on the ear for a gentle, secure fit. This lets you listen to music while staying aware of your surroundings during outdoor activities like running or cycling, so you can hear approaching cars or other hazards. Note: you may need to increase the volume slightly to achieve the desired sound. - 42 hours total playtime and digital display: On a single full charge, the earbuds provide up to 4 hours of playtime. The charging case adds additional charges for a total of 42 hours of listening. A smart LED Power Display shows the remaining battery in real time, helping you manage power without interruption. - Amazing stereo sound with strong bass: Equipped with 16.2 mm vibrating diaphragm speaker drivers, three times larger than many wireless earbuds, delivering pure balanced audio and clear output across genres. Uses directional audio technology to enable clearer phone conversations. Crystal-clear mids and highs with deep, impactful bass for an immersive sound experience. - Bluetooth 5.4 and One-Step pairing: The bone conductive earbuds use advanced Bluetooth 5.4 technology for faster transmission and more stable connections. Open the charging case cover, pick up the earphones, then select "M79" in your phone's Bluetooth list to connect. After the first successful pairing, the earbuds automatically reconnect to the previously paired device, with no need to pair again. - Practical use scenarios: - Outdoor exercise: run or cycle while staying aware of traffic and surroundings. - Calls on the go: clear audio quality for conversations despite ambient noise. - Everyday listening with long hours of use: extended battery life supports long commutes, workouts, and daily listening without frequent recharging.
