Both Pixel Buds Google Sells Have Noise Cancelling

Google’s US store sells two Pixel Buds, Pixel Buds Pro 2 and Pixel Buds 2a, and both have Active Noise Cancellation and Transparency mode. What separates them is the charging case, the microphones, a set of listening features and battery life, not whether they cancel noise, according to the Google Store read on 22 October 2026.

Both use Google’s Tensor A1 chip, Bluetooth 5.4, an 11 mm driver and IP54-rated earbuds. The Pro 2 adds a Qi wireless charging case, a third microphone per earbud, Adaptive Audio and spatial audio with head tracking, and Google rates it for more listening time.

From the Google Store compare page and each model’s Tech Specs page, read 22 October 2026.

The compare page also lists Hearing Wellness, a low-latency gaming mode and answering calls with a nod for the Pro 2 only, and the Pro 2’s Tech Specs page lists a ringtone speaker in the case for Find Hub. Each earbud weighs 4.7 g with the medium tip in both models, and both come with four tip sizes and a twist-to-adjust stabilizer.

Noise cancelling on both

Google names two generations of its seal, Silent Seal 2.0 on the Pro 2 and 1.5 on the 2a, but publishes no figure comparing how much noise each removes, so this page cannot rank them. What the spec sheets do show is that the Pro 2 carries the automatic features: Adaptive Audio and Conversation Detection, which the 2a’s compare column marks with a dash. How well any pair cancels also depends on the seal in your ear, as we explain in why noise cancelling handles hum better than voices. Samsung’s and Apple’s ranges are set out in which Galaxy Buds model is which and which AirPods have noise cancelling.

Battery, as Google states it

Model	Earbuds, ANC on / off	With case, ANC on / off	5-minute charge
Pixel Buds Pro 2 (affiliate link to Amazon, opens in a new tab)	8 / 12 hours	30 / 48 hours	Up to 1.5 hours, ANC off
Pixel Buds 2a (affiliate link to Amazon, opens in a new tab)	7 / 10 hours	20 / 27 hours	Up to 1 hour, ANC on

With noise cancelling on, Google rates the Pro 2 one hour longer on the earbuds alone and 10 hours longer with the case. The gap with the case widens to 21 hours with noise cancelling off. Google measured these at 50% volume on pre-production hardware and says real battery life may be lower.

The fast-charge figures are stated under different conditions, one with noise cancelling off and one with it on, so they do not show which pair recharges faster.

Prices

Model	Price, US Google Store, 22 Oct 2026
Pixel Buds Pro 2	$229
Pixel Buds 2a	$129

The Store showed one price for each, with no crossed-out price beside it. Other retailers may charge less.

What else separates them

Wireless charging is a Pro 2 feature. Google lists Qi-certified wireless charging for the Pro 2 case and only a USB-C port for the 2a’s, so the 2a case does not charge on a pad.

Calls get more hardware on the Pro 2. Google lists three microphones and a voice accelerometer per Pro 2 earbud against two microphones on the 2a. Both list Clear Calling, wind-blocking mesh covers and Bluetooth Super Wideband, which Google says needs a Pixel 8 or newer.

Multipoint is on both, but off by default. Google’s help page says Pixel Buds 2a (affiliate link to Amazon, opens in a new tab) and Pro hold connections to two devices, including laptops, tablets, TVs and iPhones, and switch to a call on the other device. Turn Multipoint on in the phone’s Bluetooth settings or the Pixel Buds app.

Spatial audio needs a Pixel phone. The compare page says it works only on a Pixel 6 or newer Pixel phone; the earbuds page adds the Pixel Tablet and excludes Pixel A-series phones. Head tracking is listed for the Pro 2 alone.

iPhone owners get Bluetooth basics. Google says both pair with any Bluetooth 4.0 or later device, including iOS, but full access to features needs an Android 6.0 or newer phone and a Google Account, and the Gemini features need the Gemini app on Android.
