The Google Pixel Buds 2a use an in-ear fit and come with wingtips included to help keep them securely in place during use. They are true wireless earbuds with no cables or neckband, and each earbud weighs 9.4 g. For protection against moisture, they carry an IP54 and IPX4 rating, making them sweat resistant — though they do not feature UV light or a display. The earbuds support stereo speakers and have no RGB lighting.
The Google Pixel Buds 2a include both active noise cancellation (ANC) and passive noise reduction, giving listeners two layers of sound isolation. Audio is handled by an 11 mm driver unit covering a frequency range of 20 Hz to 20,000 Hz. The earbuds do not support spatial audio, Dolby Atmos, or Dirac Virtuo, and they do not use a neodymium magnet in their driver construction.
The Google Pixel Buds 2a offer 10 hours of battery life per charge, which drops to 7 hours when active noise cancellation is in use. The included charging case extends total playback to 27 hours, and the earbuds feature a rechargeable battery with a battery level indicator to keep track of remaining charge. Wireless charging and solar power are not supported.
The Google Pixel Buds 2a connect wirelessly via Bluetooth 5.4 with a maximum range of 10 m, and they support fast pairing for quick device setup. Charging is handled through a USB Type-C port. On the codec side, the earbuds do not support LDAC, LDHC, AAC, Auracast, or any variant of aptX, including aptX Adaptive, aptX HD, aptX Low Latency, aptX Lossless, and aptX Voice. Bluetooth LE Audio and NFC pairing are also not available.
The Google Pixel Buds 2a include an ambient sound mode for awareness of surrounding audio, along with a mute function and voice prompts for hands-free feedback. They can be used as a headset and feature an on-device control panel, a find-device function, and support for fast charging. A travel bag is included in the box. The earbuds do not offer notification readout, a built-in translator, a body temperature sensor, or a camera remote shutter function.
The Google Pixel Buds 2a are equipped with 4 microphones that include noise-canceling capability, helping to reduce unwanted background sound during calls and voice input.
