True Wireless In-Ear Headphones
Product Description
Enjoy true audio freedom with these Lenovo True Wireless In-Ear Headphones. These wire-free earbuds pair with most any Bluetooth-compatible mobile device, receiving audio from up to 49' away. Audio is played through the Realtek RTL8763BFP processor and 5.8mm drivers, which are engineered to provide clear and accurate sound reproduction.
For additional functionality when on the go, a built-in microphone lets you make hands-free calls when paired with a smartphone, and it can also be used to interact with a digital assistant. Integrated touch controls let you easily manage music, calls, and interact with your device's voice assistant. The earbuds have enough power in their internal batteries for up to 4 hours of continuous playback, but a charging case is included, which provides an additional 6 hours of power. Simply place the earbuds inside to immediately begin the recharging process. The case is made to fully recharge your earbuds in up to 1 hour. The case itself recharges in up to 3 hours via USB Type-C.
