Sony WF-C510 Truly Wireless Bluetooth Earbud Headphones, Black

Truly wireless earbuds have become a daily companion for a lot of people, whether the goal is listening to music on a commute, taking calls without holding a phone, or staying aware of what’s happening nearby. The Sony WF-C510 sits in that everyday space, and the supplied product information describes a compact, colorful pair of Bluetooth earbuds built around a handful of practical features: long battery life, quick charging, multipoint connection, ambient sound, hands-free calling, water resistance, and a small charging case. This review walks through what the listing states, what those features mean in practice, and who the earbuds may suit.

Design and Fit

Sony describes the WF-C510 as light and compact, with a design intended to give all-day comfort and an ideal fit. The earbuds are positioned as an all-round listening option rather than a specialized model, and the emphasis on a comfortable fit suggests the physical design is meant to support extended wear rather than short sessions only.

The package includes hybrid silicone earbud tips. Earbud tips are the part that sits inside the ear canal, and the hybrid silicone construction is the material Sony specifies. The listing does not state how many sizes are included, so it is worth checking the packaging details if tip size matters to you. The earbuds themselves are described as compact, which aligns with the overall “colorful and compact” framing in the product information.

The charging case is described as small and cylindrical, made to fit in a pocket or a bag. That cylindrical shape is a little different from the flatter, pebble-style cases common in the category, and the pocket-friendly sizing is a stated design goal rather than a measured dimension. The earbuds are available in black, which is the color referenced in the product title.

Features and Technology

The WF-C510 includes several features that shape how the earbuds are used day to day.

• Multipoint connection: The earbuds can quickly switch between two devices at once. In practice, that means you could be connected to a phone and a laptop simultaneously and move between them without repairing.
• Ambient Sound Mode: This keeps you aware of your surroundings, which is useful when you want to hear traffic, announcements, or someone speaking to you without removing the earbuds.
• Built-in microphone: Hands-free calling is supported, so you can take calls without taking your phone out of your pocket.
• IPX4 water resistance: Sony states that splashes and sweat won’t stop these headphones, so you can keep moving to the music. IPX4 is a resistance rating, not a waterproofing guarantee, and the listing does not claim the earbuds can be submerged.
• DSEE: This feature is described as boosting the quality of compressed music files, with the aim of enjoying streaming music with high-quality sound. DSEE is a processing feature, and the listing presents it as a way to improve compressed audio rather than a change to the source file itself.
• Button operation: Play, stop, skip tracks, adjust volume, access your smartphone’s voice assistant, and receive calls hands-free with the touch of a button.

The product information also mentions that the earbuds are equipped with features designed for excellent sound quality, anytime and anywhere. That is a stated design intent rather than a measured result, and it is worth reading alongside the DSEE description, which is the specific sound-related technology named in the listing.

Battery Life and Charging

Battery life is one of the more concrete points in the supplied information. Sony states up to 11 hours of battery life on the earbuds, and up to 22 hours with the charging case. Quick charging is also included: a 5-minute charge provides up to 1 hour of playback.

Those figures are described as maximums (“up to”), so real-world results can vary with volume, feature use, and other conditions. The charging case is the cylindrical, pocket-sized unit mentioned earlier, and it is included in the box. One detail worth noting is that the charging cable is sold separately, so you will need to supply a compatible cable if you don’t already have one.

Everyday Experience

Putting the features together, the WF-C510 is positioned for regular, mixed use. The combination of up to 11 hours per charge and a case that extends total listening to up to 22 hours means the earbuds are intended to get through a long day without frequent trips to a charger. Quick charging adds flexibility for the moments when the battery is low and you only have a few minutes before heading out.

Multipoint connection and the built-in microphone support the calling side of things. If you move between a phone and a computer during the day, the two-device switching is the feature that matters most, and hands-free calling means you can answer without reaching for your phone. Ambient Sound Mode is the counterpart for when you want to stay tuned in to your environment, which is a common need when walking, commuting, or working in a shared space.

The IPX4 rating is relevant for workouts and outdoor use, since Sony states that splashes and sweat won’t stop the headphones. That said, the listing does not describe the earbuds as waterproof, so heavy rain or immersion is not covered by the stated rating.

Button controls cover the essentials: playback, track skipping, volume, voice assistant access, and call handling. The listing describes these as button operations, which is a different interaction style from touch controls, and it means the controls are physical rather than gesture-based.

Compatibility and Connectivity

The WF-C510 is a Bluetooth earbud model, and the multipoint feature allows quick switching between two devices at once. The listing does not specify which Bluetooth versions or codecs are supported, so if you need those details, they are not covered in the supplied information. The voice assistant feature is described as accessing your smartphone’s voice assistant, which indicates phone-based assistant use rather than a built-in assistant on the earbuds themselves.

Who Is This Product Best For?

Based on the stated features, the WF-C510 is a reasonable fit for people who want a compact, everyday pair of Bluetooth earbuds with long battery life and a case that fits in a pocket or bag. The multipoint connection and hands-free calling suit anyone who regularly moves between two devices or takes calls on the go. Ambient Sound Mode is useful for those who want to stay aware of their surroundings, and the IPX4 rating is relevant for workouts and outdoor activity where sweat and splashes are a factor. The DSEE feature may appeal to listeners who stream compressed music and want the earbuds to process that audio.

Because the listing does not specify tip sizes, codec support, or exact dimensions, anyone with specific fit or compatibility requirements should verify those details before deciding.

Final Verdict

The Sony WF-C510 is a compact, feature-focused pair of truly wireless Bluetooth earbuds. The supplied information highlights up to 11 hours of battery life, up to 22 hours with the case, quick charging, multipoint connection, Ambient Sound Mode, hands-free calling, IPX4 water resistance, DSEE processing, and button controls. The package includes the earbuds, hybrid silicone tips, and the cylindrical charging case, with the charging cable sold separately.

What the listing does not provide is equally worth noting: there are no stated codec details, no tip size count, no measured dimensions, and no performance claims beyond the design intent for sound quality. The battery figures are maximums, and the IPX4 rating covers splashes and sweat rather than full waterproofing. For a shopper who wants a pocketable everyday pair with strong stated battery life and practical connectivity features, the WF-C510 is a straightforward option to consider, provided the unspecified details don’t matter for your particular setup.
