Sony WF-C710N / Samsung Galaxy Buds3 (SM-R530)

The figures are for one charge of the earbuds; total time with the case is not listed on Sony's page.

Wireless charging is not listed for the case.

There is no LDAC or aptX; AAC is a common codec that works well with iPhones and most Android phones.

The earbuds stay connected to two devices at once, so a phone call can be answered while listening on a computer.

Quick Attention lowers the music and lets outside sound in while a finger is held on the earbud. DSEE aims to restore high frequencies lost in compressed music.

IPX4 protects against splashing water; the earbuds should not be submerged.

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

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).

Some features are not available on non-Samsung devices.
