Sony WF-C510 Truly Wireless Earbuds – 22-Hour Battery

Sony WF-C510 are compact truly wireless in-ear earbuds that deliver long battery life, multipoint pairing, ambient awareness and splash resistance for everyday listening.

These butter-yellow Sony earbuds combine a small, pocket-size charging case with features meant for commuting, workouts, and hands-free calls. Lightweight hybrid silicone tips and an ergonomic shape prioritize comfort, while Sony’s DSEE logic improves the clarity of streamed or compressed tracks. Quick charging and multipoint connectivity make these buds convenient for users who switch between phone and laptop.

How long will the battery keep me listening?

The WF-C510 provide up to 11 hours of playback per full earbud charge and up to 22 hours total when you include the charging case. A five-minute quick charge delivers roughly one hour of playback, so short top-ups are effective when you’re pressed for time.

• 11 hours per earbud on a single charge
• Up to 22 hours total with the charging case
• 5-minute quick charge → about 1 hour of playback
• USB cable for charging (cable sold separately in some regions)

Can I use these with multiple devices at once?

Yes — Multipoint Connection lets the WF-C510 stay linked to two devices simultaneously, so you can listen on a laptop and quickly answer calls from your phone. Switching between paired devices is automatic and avoids the hassle of repeated re-pairing.

• Supports two-device simultaneous pairing
• Automatic switch to incoming calls from either device
• Works with phones, tablets and computers that support Bluetooth audio
• Easy re-connection through standard Bluetooth pairing

Will they survive sweat and light rain?

The WF-C510 carry an IPX4 water resistance rating, meaning they resist splashes and sweat but are not intended for full submersion or heavy water exposure. They’re suitable for gym sessions, light outdoor activities and everyday commuting in rainy weather.

• IPX4 splash and sweat resistance
• Not rated for swimming or showering
• Designed for active use and casual outdoor wear
• Wipe dry after exposure to moisture to preserve longevity

How do they handle calls and sound quality?

A built-in microphone enables hands-free calls and voice assistant access through button controls, and Sony’s DSEE restores detail to compressed audio for clearer playback. Ambient Sound Mode keeps you aware of surroundings while listening, useful for street safety or brief conversations without removing earbuds.

• Integrated mic for clear hands-free calling
• Button controls for playback, volume, and voice assistant
• DSEE improves compressed music quality
• Ambient Sound Mode lets in environmental noise when needed

Who is this for: The Sony WF-C510 suit users who want reliable, comfortable wireless earbuds with long battery life and practical features for daily life — commuters, remote workers, students, and casual fitness users. They’re a good match if you value portability, easy multipoint switching between devices, and splash resistance without the bulk of larger true wireless models.
