The Sony WF-C510 is an appealing answer to a straightforward request: compact wireless earbuds that sound good, last through a long day and do not cost flagship money. Its feature list is deliberately selective. Multipoint and an ambient listening mode are welcome, while the absence of active noise cancellation is the main compromise to understand before buying.
Sony WF-C510 — Design and everyday controls
Sony’s small rounded earbuds take a different approach from a long-stem design. The compact case is easy to carry, and physical controls offer a clear alternative for people who dislike touch panels. Comfort still depends on the shape of the ear rather than the overall size of the product. Small housings can be convenient without necessarily fitting everyone.
SoundGuys’ original review finds the C510 dependable, with good fit and useful battery life. It notes that the buds sit fairly far into the ear. That observation makes a proper fit check worthwhile for anyone who dislikes pressure around the canal entrance or has found sealed earbuds uncomfortable in the past.
Try each supplied tip size rather than assuming the factory-fitted pair is correct. A stable seal improves both bass and passive isolation. If the fit loosens while walking or talking, changing tips is more useful than compensating with equalisation. The two ears may also need different sizes.
Sound quality
SoundGuys reports an enjoyable overall sound and suggests that listeners seeking more bass may want to use the app’s equaliser. Its assessment supports the C510 as a capable affordable music product, without suggesting that it replaces a premium earbud in every respect. There is no Audio Review listening test behind that observation.
For the buyer, the useful question is whether the balance works with ordinary music at ordinary volume. Listen to a singer, a bass-led production and a busy arrangement. Voices should remain easy to follow when the low end becomes active, and percussion should retain enough definition without becoming distracting.
The Sound Connect app provides a way to adjust the presentation. Start from the standard setting, then change one control at a time. A little extra bass may be welcome in a quiet room, but a poor seal can make any preset inconsistent. Solve the physical fit before deciding how much tonal adjustment is necessary.
Sony includes DSEE processing, but that feature should not dominate the purchase. A comfortable fit, stable Bluetooth link and suitable tuning have a much more obvious role in daily satisfaction. Nor does an additional processing mode mean every stream is transformed into a higher-resolution recording. Judge the audible result and the effect on battery use rather than the name.
No ANC, but an ambient mode
The C510 does not provide active noise cancellation. It relies on the ear tips and sealed fit to reduce outside sound. Passive isolation can help with some higher-frequency noise, but it is less effective against the persistent low rumble that good ANC systems target. This distinction is crucial for train passengers and frequent flyers.
Ambient Sound allows outside audio through the microphones so that a short conversation is more convenient without removing the earbuds. This is a separate function from noise cancellation. The presence of one does not imply the presence of the other, even though both use microphone processing.
For office use, passive isolation may be entirely sufficient if the room is reasonably calm. For a loud daily commute, the extra cost of an ANC model may produce a greater practical improvement than a higher audio codec specification. Choose according to the environment in which most listening happens.
Keep ambient mode expectations realistic. It is a convenience function, not a guarantee of awareness of every vehicle or warning sound. Music itself can mask the surroundings even when some outside audio is audible. Lowering playback level is still an important part of listening comfortably outside.
Bluetooth, app and calls
Sony lists Bluetooth multipoint, which lets the earbuds maintain connections to two devices. That is useful for someone moving between a laptop and a phone. Multipoint is about managing connections; it does not mean two independent audio streams are mixed together for simultaneous listening.
The supported music codecs are SBC and AAC. That is a sensible baseline for Android and iPhone use, even though buyers seeking LDAC will need a different model. A codec logo cannot compensate for an unsuitable fit or poor tuning. For routine streaming, connection reliability and convenient switching are more relevant than collecting every format.
The app is worth using to check firmware and control options. Once the preferred settings are established, everyday playback should not require constant attention to it. If these are primarily computer earbuds, confirm which adjustments remain stored after setup from a phone.
Calls are another reason to assess the actual use case. SoundGuys’ microphone samples and commentary show that noise handling varies with the environment. Occasional calls are a different requirement from several hours of professional meetings. For critical work, test the earbuds in the room where calls will occur rather than assuming a microphone count predicts intelligibility.
Battery and charging
Sony advertises up to eleven hours from the earbuds under specified conditions, with some processing and ambient features disabled. SoundGuys obtained ten hours and twenty-nine minutes in its own rundown with transparency off. That independent result is useful evidence of strong single-charge endurance, but it is not a guarantee for every volume or feature combination.
Single-charge time and the case’s total contribution should be compared separately. Long earbud endurance helps on a continuous journey because returning them to the case interrupts listening. A larger total number does not mean the earbuds can play for that whole period without a charging break.
The case uses USB-C and does not offer wireless charging. That is an understandable omission in an affordable product. If an existing routine already uses a USB-C cable for several devices, it is unlikely to be a serious inconvenience. If wireless charging is essential, compare another model directly rather than assuming it can be added later.
Durability and value
The earbuds have an IPX4 splash-resistance rating. That supports ordinary exposure to splashes within the rating’s limits; it does not make them suitable for swimming or establish dust protection. Dry the earbuds before charging and keep the case away from water unless its own documentation explicitly allows exposure.
The C510 offers its best value to someone who wants compact, straightforward earbuds and can accept passive isolation. Its long single-charge endurance and multipoint are more meaningful advantages than a long list of marginal features. The absence of ANC becomes a larger compromise as the listening environment gets noisier.
Compare current European offers against entry-level ANC earbuds, including warranty and return arrangements. A good discount can make the C510 a very sensible purchase, but a small price gap to a better-suited noise-cancelling model may change the recommendation. The correct choice follows daily use rather than a fixed hierarchy of model numbers.
Alternatives to consider
Sony WF-C710N: The more relevant comparison when the main reason to upgrade is active noise cancellation.
Nothing Ear (a): A different design and feature balance to compare if app features and ANC matter more than the C510’s simplicity.
Soundcore Liberty 4 NC: An alternative worth considering for a noisy commute, with fit and the actual local price deciding its value.
