The LG TONE Free T90 is the world's first Dolby Atmos wireless earbuds that enhance listening experiences with Dolby Head Tracking across all your favorite entertainment like music, movies, TV shows and games. You can experience Dolby Head Tracking with your LG TONE Free T90. With Dolby Head Tracking, as you turn your head, the audio recalibrates to enable a more natural sound experience for Dolby Atmos and other entertainment content, so you're always in the center of the scene. Plus, as the first wearable with an integrated audio virtualizer by Dolby, the LG TONE Free T90 adds dimensionality and clarity to your stereo entertainment. In addition, the advanced Active Noise Cancellation (ANC) has a Voice Pickup Unit added to the microphone, which clearly discerns your voice and reduces unwanted background noise. And with Plug & Wireless+ and the TONE Free app, you can listen to your favorite shows, movies and music on devices even without Bluetooth capabilities, like inflight entertainment or on a treadmill at the gym. And now you can even host and take a conference call, all without Bluetooth. The T90 also includes a convenient UVnano+ charging case that harnesses the power of UV-C light (also called germicidal UV) to refresh the earbuds eargels. It effectively kills 99.9% bacteria on the eargels of the earbuds during the powered charging cycle. In just 10 minutes, the eargels are sanitized and have power to go. Plus, you can do your thing in comfort with soft, hypoallergenic medical grade eargels that provide a comfortable fit and help prevent irritation.
