Sony WF-C510

The Sony WF-C510 true wireless earbuds nail comfort and connectivity with a super lightweight design and flawless Bluetooth 5.3. Sound quality is great for the price, especially after EQ tweaks. But a widespread pattern of the left earbud failing and charging issues makes them a risky buy despite the low cost.

Out of the box, the 6mm drivers deliver a sound that's well above average for this price bracket, landing in the 80th percentile in our database. It's a clean, balanced profile that responds wonderfully to EQ tweaks in the Sony Headphones Connect app. Bass isn't going to rattle your skull, but it's present and controlled. The real star is the clarity and soundstage, which gets a nice boost from DSEE. For music, it's a solid 75 out of 100 in our scoring, which is respectable for budget-focused buds. But where they truly shine is connectivity. With a 100th percentile ranking, the Bluetooth 5.3 connection is rock-solid, and multipoint switching is flawless.

The battery life is decent, sitting in the 66th percentile. You'll realistically get through a full workday on a single charge, and the case tops you up for a total of 22 hours. The quick charge is genuinely useful for a pre-commute panic top-up. The mic, however, is a weak spot at the 34th percentile. It's passable for a quick call in a quiet room, but don't expect to sound clear on a windy street. The lack of active noise cancellation is a trade-off, but the passive seal is decent. The Ambient Sound mode works as advertised, though it's not as natural-sounding as what you'd find on pricier AirPods.

Stacked against the Samsung Galaxy Buds3 Pro, the Sony WF-C510 are in a completely different league, and that's okay. The Buds3 Pro are a flagship with top-tier ANC and a much higher price tag. The Sony's real fight is with the EarFun Air Pro 4+ and the Soundcore P31i. The EarFun offers active noise cancellation and a more reliable reputation among owners, making it a safer bet for commuters. The Soundcore P31i is often cheaper and delivers thumpier bass out of the box. The Sony's trump card is its featherlight comfort and superior button controls. If you hate touch panels and want the most ergonomic fit, the WF-C510 win. But if you need your earbuds to last more than a year without a trip to the warranty center, the competition starts looking a lot more appealing.

The value proposition here is a real rollercoaster. On features alone, getting this level of comfort, connectivity, and sound in a sub-$100 package is a steal. You're getting Sony's audio processing and a fantastic app experience for the price of a dinner out. But that value crumbles if the earbuds die on you in six months. Compared to something like the EarFun Air Pro 4+, which throws in solid ANC and a more robust track record for a similar price, the Sony's long-term value becomes a gamble. You're paying for a premium experience that might have an expiration date.

The Sony WF-C510 are the kind of earbuds you grab when you want something that just disappears in your ears. At around 3 grams per bud, they're absurdly light, and Sony's ergonomic design means you can wear them for hours without that annoying ache you get from bulkier sets. If you've been searching for comfortable true wireless earbuds for commutes or all-day office use, these are a strong contender, especially given they often dip into the $40 to $100 range. You get a pocket-sized case, physical buttons instead of finicky touch sensors, and an IPX4 rating that'll handle sweat and light rain without a fuss.

Sony packed in some nice audio tricks too. DSEE upscaling aims to breathe life into compressed tracks, and there's support for 360 Reality Audio for spatial sound. The Ambient Sound mode is a transparency feature that pipes in your surroundings, so you don't have to pull a bud out to order coffee. Connectivity is best-in-class with Bluetooth 5.3 and multipoint, letting you hop between a laptop and phone seamlessly. But there's a catch, and it's a big one: long-term reliability. Our data shows user sentiment is shockingly low, with a pattern of the left earbud dying or developing audio distortion after a few months.

For the price, the feature set is genuinely impressive on paper. You get up to 11 hours of playback from the buds and another 11 in the case, plus a quick charge that gives you an hour of juice in 5 minutes. The sound, once you tweak the EQ in Sony's app, is detailed and enjoyable. But the glowing spec sheet crashes hard against the reality of ownership for a lot of people. This is a classic case of a product that's fantastic when it works, but the question of "for how long?" looms large.

Skip the Sony WF-C510 if reliability is a top priority for you. The pattern of left earbud failures is too common to ignore, making them a poor choice for anyone who needs a dependable daily driver for work calls or commutes. If you're a heavy call user, the mediocre mic quality will also be a letdown. Look at the EarFun Air Pro 4+ for a more reliable package with active noise cancellation, or the Soundcore P31i for a bass-forward, durable alternative that won't break the bank.

The Sony WF-C510 are a frustrating pair of earbuds to score. When they're working, they're a genuine joy. The fit is so good you'll forget you're wearing them, the physical buttons are a tactile dream, and the sound is rich and customizable. For someone who prioritizes comfort and a no-fuss physical interface above all else, and who can snag them on a deep discount, they might be worth the risk. But we can't ignore the data. The user sentiment score is a brutal 3rd percentile, driven by a consistent drumbeat of left earbud failures and charging issues.

Should you buy these? Only if you're prepared to treat them as potentially disposable and you absolutely must have that specific Sony fit and button layout. The reliability concerns are not isolated incidents, they're a pattern. For most people, we'd strongly recommend looking at more dependable alternatives from EarFun or Soundcore that offer similar or better features without the looming threat of a premature death. It's a real shame, because Sony nailed the fundamentals of what makes a daily-driver earbud great, then fumbled the part where it keeps working.
