Samsung Galaxy Buds3 FE (SM-R420) / Samsung Galaxy Buds3 (SM-R530)

Silicone tips seal the ear canal, blocking outside sound passively and helping bass sound fuller; if the tip does not seal, noise cancelling and bass both weaken.

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

ANC uses microphones to detect outside sound and plays inverted sound to reduce steady noise such as engines and hum. Ambient sound lets you hear your surroundings without removing the earbuds. Adaptive ANC that adjusts to the environment is not listed for this model.

SSC is Samsung’s own codec for higher-quality audio with Galaxy devices; other phones use AAC or SBC. Auto Switch moves the connection automatically between Galaxy devices on the same account.

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.

Samsung’s times come from internal tests with pre-production units and default settings; rated capacity is 50 mAh per earbud and 500 mAh for the case. Real runtime depends on volume, codec and battery age.

IP54 means limited dust protection and resistance to splashing water from any direction; it is not suitable for submersion. The charging case is not protected.

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

Samsung notes some features may be unavailable on non-Samsung devices. Equaliser, ANC settings and AI features are managed in the Galaxy Wearable app or One UI settings.

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.

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.

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).
