Sony WF-C510 True Wireless Earbuds – 22H Battery, Multipoint

Compact Sony WF-C510 true wireless earbuds deliver balanced sound, up to 22 hours of total playtime, multipoint switching between two devices, and splash-resistant design for daily use.

These lightweight in-ear headphones are built for everyday listening, commuting and hands-free calls. With up to 11 hours per bud and an additional 11 hours from the pocket-sized charging case, the WF-C510 keeps your playlists going. Sony’s DSEE audio restoration, Ambient Sound mode, and a built-in mic round out a feature set aimed at convenience, clear calls and better-sounding streaming without bulky hardware.

How long will the battery last during a day of use?

You can expect up to 11 hours of continuous playback from the earbuds alone, and up to 22 hours when you include the charging case. A quick 5-minute charge gives roughly an hour of listening, which helps when you need fast top-ups between activities.

• Earbud runtime: up to 11 hours on a single charge
• Case adds: up to 11 additional hours, total 22 hours
• Quick charge: 5 minutes ≈ 1 hour playback
• Charging cable: sold separately (case included)

Can I use these buds with two devices at once?

Yes—the WF-C510 supports multipoint connection so you can stay linked to two Bluetooth sources simultaneously. That makes switching between a laptop and phone seamless for calls, music and notifications without repeated pairing.

• Pair two devices and switch automatically
• Works for calls and media on both paired devices
• Saves time versus manual reconnection
• Reconnection is automatic once devices are in range

Will these survive workouts or rainy commutes?

The earbuds have an IPX4 splash-resistance rating, so they tolerate sweat and light splashes but are not intended for submersion. Combined with a snug, lightweight fit, they’re well suited to gym sessions, running in light drizzle, or daily errands where moisture exposure could occur.

• IPX4 water resistance for sweat and light splashes
• Compact, secure in-ear design for active use
• Not rated for swimming or heavy rain immersion
• Easy button controls keep interaction simple while moving

How do the sound features and call functions perform?

Sony’s DSEE technology helps restore detail to compressed tracks so streamed music sounds fuller, while the built-in microphone supports hands-free calling without grabbing your phone. Ambient Sound mode lets background noise in when you need awareness, like crossing streets or hearing announcements.

• DSEE restores lost high-frequency detail in compressed audio
• Built-in mic for clear hands-free calls
• Ambient Sound mode maintains environmental awareness
• Button controls for playback, volume, assistant and calls

Who is this for? The Sony WF-C510 suits commuters, casual listeners and active users who want a small, comfortable wireless earbud with solid battery life, simple multipoint switching and splash resistance. If you stream music, take frequent calls and need a pocketable case plus straightforward controls, these earbuds offer a balanced mix of convenience and sound-enhancing features without extra bulk.
