Sony WF-C510 Wireless Earbuds — 22H Battery, IPX4

These are Sony WF-C510 truly wireless in-ear earbuds — compact, water-resistant headphones with up to 22 hours of combined battery life, multipoint pairing, a built-in mic, and smart audio features.

Designed for everyday listening, the WF-C510 offers a lightweight fit, on-ear controls, and sound enhancement technology to improve compressed streams. The earbuds are sold renewed in white, pair with two devices simultaneously, and include a pocket-sized charging case for extended use. Quick-charge capability helps you get an hour of playback after only five minutes on the charger, while IPX4 splash resistance keeps them working through sweat and light rain.

How long will the battery last during my day?

A single earbud charge delivers up to 11 hours of playback, and the included charging case provides an additional 11 hours for a total of up to 22 hours. If you’re short on time, a five-minute quick charge gives roughly one hour of listening so you can get moving quickly.

• Earbuds alone: up to 11 hours playback
• With charging case: up to 22 hours total
• Quick-charge: 5 minutes ≈ 1 hour play
• Charging cable sold separately

Can I switch between phone and laptop without re-pairing?

Yes — multipoint connection lets the WF-C510 stay linked to two devices at once and switch audio automatically based on what’s playing or which device rings. This is useful for answering calls on your phone while watching video or listening to music from a second device.

• Pair two devices simultaneously
• Automatic switching for calls and media
• Saves time versus manual reconnecting

Will these survive workouts and rainy commutes?

The earbuds have an IPX4 splash-resistance rating, protecting them from sweat and light splashes so they remain usable during exercise and in mild weather. They are not fully waterproof, so avoid submersion and heavy downpours.

• IPX4 rating: splash and sweat resistant
• Not rated for swimming or full immersion
• Compact case fits in pockets or small bags

How do the sound and controls improve everyday use?

Sony’s DSEE technology restores detail to compressed tracks, while Ambient Sound Mode lets you hear surroundings for safety or short conversations without removing the earbuds. Intuitive button controls handle playback, volume, voice assistant access, and hands-free calls.

• DSEE improves compressed audio quality
• Ambient Sound Mode keeps you aware of environments
• On-ear buttons for music, calls, and assistant access
• Built-in mic for hands-free calling

Who is this for? The WF-C510 is a practical choice for commuters, casual listeners, and active users who want compact, comfortable earbuds with long battery life, reliable wireless switching between two devices, and basic water resistance. If you need advanced noise cancellation or full waterproofing, consider higher-tier models, but for everyday music, calls, and workouts, these renewed Sony earbuds deliver balanced features and portability.
