Samsung Galaxy Buds4 Pro / Samsung Galaxy Buds3 (SM-R530)

Separate drivers for bass and treble aim for better separation than a single driver covering both.

Voice Detect lowers the music and lets in ambient sound when you start talking.

Auto Switch moves the connection between Galaxy devices on the same Samsung account; Auracast lets several headsets join one broadcast.

Head gestures let you accept or reject a call by nodding or shaking your head.

IP57 limits dust ingress and survives brief immersion; the case is not stated to have the same rating.

Because there is no iPhone app, features such as EQ and ANC settings are not available on iOS.

Some features are not available on non-Samsung devices.

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.
