Hear music, calls and mobile audio through closed-back, in-ear true wireless earbuds with 11 mm dynamic drivers and stereo sound. Pixel Buds Pro 2 combine Google Tensor A1 processing with Silent Seal 2.0 adaptive active noise cancellation, which adjusts noise reduction to the surrounding environment. Three MEMS voice microphones per earbud support voice pickup for calls, while built-in controls keep playback and call functions on the earbuds. Bluetooth 5.4 provides the wireless audio connection, with mobile-app compatibility for Android and iOS. The earbuds pair with one device at a time and do not support multipoint connections or wired audio. Spatial audio with head tracking adds a positional listening mode for supported content and devices. Sensors including gyroscope, infrared and proximity sensing support wear detection and interaction functions. Google GA05762-US supplies the Hazel Pixel Buds Pro 2 package with a wireless charging case and eartip pairs in four sizes. Each earbud provides up to 8 hours of playback with active noise cancellation on, or up to 12 hours with it off; the case extends total ANC-on playback to up to 30 hours. A 5-minute charge supplies up to 1.5 hours of playback. USB-C and wireless charging support flexible case charging, while the earbuds carry an IP54 water-resistance rating for everyday sweat and dust exposure.
