Sony WF-C510 Ultra Compact Truly Wireless Earbuds

From the outset these earbuds make a strong impression as a well-rounded choice for everyday listening. The WF-C510 are designed with a focus on comfort, simplicity and value, rather than high-end extras. In terms of styling and fit they are described by the manufacturer as “compact and light” for all-day wear. Each earbud weighs approximately 4.6 g, making them among the lighter wireless models available.

Sound-wise, these earbuds use 6 mm dynamic drivers and support both SBC and AAC Bluetooth codecs. They also include Sony’s Digital Sound Enhancement Engine (DSEE) which is intended to improve the quality of compressed audio streams. While they don’t have active noise cancellation (ANC), they do offer Ambient Sound mode which allows external sounds in—useful for staying aware of surroundings. Reviewers note that, for their price class, the sound quality is “solid” and that clarity of vocals and treble is a strength.

On the battery front, the WF-C510 deliver up to 11 hours of play time from the earbuds themselves with the charging case adding another 11 hours, for up to 22 hours total. A quick five-minute charge can provide approximately one hour of playback, which is a nice touch for when you’re short on time. Charging is via USB-C, and the case is compact enough to slip into a pocket without bulk.

Connectivity includes Bluetooth 5.3, and a useful feature is Multipoint Connection (the ability to pair to two Bluetooth devices simultaneously). The water-resistance rating is IPX4, meaning they are splash resistant and suitable for sweat and light rain but not for full submersion. As for physical design the case and earbuds are small, rounded and unobtrusive: the case is described by Sony as “pocket-sized for your convenience.” 

From a stylistic standpoint, there are multiple colour options (black, blue, white, yellow) giving a bit of personal choice. On sustainability the model is built using some recycled plastics and the packaging has been designed with reduced plastic use, reflecting Sony’s environmental commitment. 

On the user experience side, the WF-C510 are particularly suitable for commuters, casual listeners, and anyone who wants good sound in a compact form without paying a premium for lots of extra features. Reviewers observe that they hit the sweet spot of usability and value: the fit is comfortable, the sound is clear, and the feature-set is appropriate for everyday use. That said, if you’re looking for advanced features such as active noise cancellation, spatial audio, tracking or very deep bass and high-end tuning, then this model may feel like a modest step rather than a leap.

It’s worth noting a few trade-offs. The case only provides one full recharge, so if you expect multi-day usage without access to a charger then you might need to top up more frequently. Also, since there is no ANC, the passive fit and isolation are your only defence against external noise—so in very noisy environments the experience will not match higher-end buds with full noise cancelling. In reviews the ambient-sound (transparency) mode is said to be “only okay”. 

In conclusion, the WF-C510 earbuds from Sony represent an excellent value proposition. Their strengths lie in a lightweight form factor, solid sound quality, ease of use, dependable battery life for everyday sessions, and good connectivity features like Multipoint. For general listening, commuting, casual workouts and daily use they deliver a competent and comfortable option at a very modest price point compared with premium wireless earbuds. If your priority is simply good-sound wireless earbuds that are easy to wear and use, these deliver. If your priorities include full-fledged noise cancellation or ultra-premium audio performance, then it might make sense to review alternatives.
