In short
Get Pixel Buds 2a for Google's noise cancelling at $129; for $229, Pixel Buds Pro 2 adds wireless charging, Silent Seal 2.0 and longer battery. Each 4.7 g bud runs Silent Seal 1.5 on Tensor A1 and lasts up to 7 hours with noise cancelling on, or 20 with the case. iPhone owners should look elsewhere, since the full feature set needs Android and a Google Account.
Who it is for
- Android and Pixel owners who want active noise cancelling without paying Pro 2 prices.
- Pixel Buds A-Series owners ready to upgrade. 2a adds noise cancelling and IP54 buds, and Google says it doubles listening time with noise cancelling off, to 10 hours from 5.
- People who struggle to keep earbuds in. The twist-to-adjust stabilizer is inspired by Pro 2's design, and there are four tip sizes to choose from.
- Gemini users. Google supports Gemini on 2a where it's available, along with the Pixel Buds app and Fast Pair on Android.
Who should skip it
- iPhone owners. 2a pairs with any Bluetooth 4.0 or newer device, but Google ties the full feature set to an Android phone and a Google Account.
- Anyone who wants wireless charging or the most battery. Pro 2 adds Qi charging and lasts 8 hours with noise cancelling on, 30 with the case, against 7 and 20 on 2a.
- Anyone who needs to hear traffic or announcements without taking a bud out. Google lists no transparency mode for 2a, and Pro 2 has one.
What sets it apart
- The first A-series Pixel Buds with active noise cancelling: Silent Seal 1.5, running on Google's Tensor A1 chip.
- With noise cancelling off, up to 10 hours from the buds and 27 in total with the case; with it on, 7 and 20.
- A 4.7 g bud with a medium tip, against 5.06 g for the A-Series, held in place by a twist-to-adjust stabilizer.
- IP54 buds and an IPX4 case; the A-Series rated only its buds, at IPX4.
Caveats
- Google doesn't list codecs or multipoint for 2a, so don't count on LDAC or on staying connected to two devices at once.
- There's no quick-charge time for 2a. Pro 2 gets about 1.5 hours of listening from five minutes in its case.

Noise cancelling comes to the A-series
The 2021 Pixel Buds A-Series had no active noise cancelling at all. 2a adds it, running on the Tensor A1 chip in each bud. Google’s launch post and help page call it Silent Seal 1.5, while the store specs just say Silent Seal, and there’s no decibel figure for how much it removes. Pixel Buds Pro 2 has the newer Silent Seal 2.0.
The custom 11 mm driver gets a new high-frequency chamber. For calls, 2a uses Bluetooth Super Wideband, wind-blocking mesh over the microphones and Google’s AI call processing.
Fit and weight
2a borrows the twist-to-adjust stabilizer from Pro 2’s design, so a twist changes how firmly the bud sits. Tips come in extra small, small, medium and large, with the medium pair fitted.
The case weighs 47.6 g with the buds inside, against 52.9 g for the A-Series. Google rates the buds IP54 for sweat and water, so a wet run is fine; a swim isn’t.
Battery: 2a, Pro 2 or the A-Series
Google’s approximate listening times:
| Spec | Pixel Buds 2a | Pixel Buds Pro 2 | Pixel Buds A-Series |
|---|---|---|---|
| Noise cancelling | Silent Seal 1.5 | Silent Seal 2.0 | None |
| Per charge | 7 hours with ANC, 10 without | 8 hours with ANC, 12 without | 5 hours |
| With the case | 20 hours with ANC, 27 without | 30 hours with ANC, 48 without | 24 hours |
| Price | $129 at launch | $229 list, $189 on sale | $99 at launch |
Pro 2 lasts longer at every step, and its case also charges on a Qi pad, where 2a’s charges over USB-C. If battery is what you’d upgrade for, the gap is biggest with noise cancelling off and the case in play: 48 hours against 27.
Controls, Gemini and finding lost buds
Touch controls on the buds handle music, calls and your digital assistant. 2a connects over Bluetooth 5.4 and sets up with Fast Pair on Android. Settings and firmware updates go through the Pixel Buds app or Android settings, and Gemini works where Google offers it.
If a bud goes missing, Google says you can see the buds on a map and ring them when they’re close by.
Price and colors
Google launched 2a at $129 on 20 August 2025 and put it in stores on 9 October. That’s $100 under Pro 2’s $229 list price, though Pro 2 has been on sale for $189, which narrows the gap.
Google’s photos show 2a in Hazel; Pro 2’s Porcelain, Olive, Peony and Wintergreen don’t appear in the 2a lineup. Sale prices move on both pairs, so check before you buy.

Frequently asked questions
Should I get Pixel Buds 2a or Pixel Buds Pro 2?
Get 2a if $129 is your budget and cable charging is fine. Pro 2 lists at $229, though it has sold for $189, and adds Silent Seal 2.0, a Transparency mode, Qi wireless charging and longer battery: 12 hours with noise cancelling off, or 48 with the case, against 10 and 27 on 2a.
Is Pixel Buds 2a an upgrade over Pixel Buds A-Series?
Yes. It adds active noise cancelling, IP54 buds instead of IPX4, Bluetooth 5.4 instead of 5.0, and a lighter 4.7 g bud against 5.06 g. With noise cancelling off, Google rates 2a at 10 hours per charge and 27 with the case, against 5 and 24 on the A-Series.
Does Pixel Buds 2a work with an iPhone?
Partly. You can pair it with an iPhone like any other Bluetooth earbuds, but the full Pixel Buds feature set needs an Android phone and a Google Account.
Does Pixel Buds 2a charge wirelessly?
Not according to Google. The case has a USB-C port, and Google lists Qi wireless charging only for the 2020 Pixel Buds, Pixel Buds Pro and Pro 2 cases.
Can you replace the battery in Pixel Buds 2a?
Yes, the case battery. Google says 2a comes with a replaceable case battery, though it gives no capacity.
