This model offers the best integration experience for Android users, especially Pixel users. Features of this model: Truly wireless: No cables, with independent left and right earbuds. Wireless charging case: Includes a compact case compatible with Qi wireless charging. You can easily charge it by simply placing it on a charging pad.

Touch & swipe controls: The touchpads on the earbud surfaces allow you to play/pause music, skip tracks, and adjust the volume with swipe gestures.
