Google Pixel Buds Pro 2 / Samsung Galaxy Buds3 (SM-R530)

Google says Tensor A1 adapts audio to the environment up to 3 million times per second and runs noise cancellation twice as strong as the original Pixel Buds Pro; music and noise-cancellation processing run on separate paths.

Pressure relief reduces the plugged-ear feeling of sealed earbuds. Conversation Detection pauses music and switches to transparency when you start talking.

The voice accelerometer picks up jaw vibration while you speak to help separate your voice from ambient noise. Google’s Clear Calling and Super Wideband calling require compatible Pixel phones.

Full features need an Android 6.0 or newer phone, a Google Account and an internet connection; basic listening works with an iPhone.

Google’s blog footnote says figures were measured on pre-production hardware with other features disabled; real-world time may be shorter.

The case speaker lets you ring a lost case through Find Hub.

The proximity sensor pauses music automatically when you take an earbud out; swiping adjusts volume.

IP54 limits dust ingress and resists splashing water from any direction; the earbuds should not be submerged. The case has no dust rating.

Google says the earbuds are 27% smaller and 24% lighter than the original Pixel Buds Pro.

The open design does not seal the ear canal, so it avoids a pressure feeling over long use but isolates less than tipped models. Fit varies with ear shape.

The VPU picks up the wearer’s voice through bone vibration to help separate speech in noisy calls.

ANC measures outside sound with microphones and produces an opposite wave to reduce steady hum; in an open design the effect is more limited than in sealed earbuds.

UHQ (24-bit/96 kHz) only works on certain Galaxy phones and tablets with One UI 6.1.1 or later (S24, S23, Z Fold6/Flip6, Z Fold5/Flip5, Tab S9 series); 24-bit Hi-Fi needs One UI 4.0 or later. Other devices use AAC or SBC.

Samsung Seamless Codec (SSC) is Samsung’s own codec for higher-resolution wireless audio with Samsung devices. Auto Switch moves the connection between signed-in Galaxy devices automatically.

The SWIR infrared sensor detects whether an earbud is worn; the Hall sensor detects the case opening and closing.

These are Samsung’s internal tests with default settings paired to a Galaxy phone. Capacity is 48 mAh per earbud and 515 mAh in the case (typical).

IP57 means dust-protected and resistant to brief immersion; the charging case is not covered.

Some features are not available on non-Samsung devices.
