How We Research
We compare products from their published specs and features; the verdicts below are our independent editorial opinions.
If you want a low-profile pair of in-ear buds with long single-charge playback and a quick-charge top-up, choose Sony WF-C510; if you need an open-ear earcuff design that keeps your ears completely unblocked and your surroundings audible, choose JVC Nearphones Pearl.
• Sony WF-C510 — biggest strength: Up to 11 hours per charge (up to 22 hours with the case), plus a 5-minute quick charge that gives up to an hour of playback.
• Sony WF-C510 — biggest trade-off: It's a traditional in-ear bud, so it physically seals your ear canal and there's no active noise cancellation to manage what you hear.
• JVC Nearphones Pearl — biggest strength: Open-ear earcuff design that sits on your ear instead of inside it, so you stay connected to your surroundings with nothing blocking the canal.
• JVC Nearphones Pearl — biggest trade-off: An open-type fit means you're not getting the passive isolation of a sealed in-ear bud, and the finish is more fashion-forward than understated.
• Who each pick is for: Sony WF-C510 for commuters, call-takers and anyone who wants a compact everyday in-ear; JVC Nearphones Pearl for people who want an open-ear, jewelry-inspired look and refuse to plug their ears.
The WF-C510 is Sony's take on the classic everyday true-wireless bud, and the spec sheet tells a coherent story. You get up to 11 hours of playback on a single charge, and the case carries roughly another 11, for up to 22 hours total. That's a genuine all-day-and-then-some number for a compact bud, and the 5-minute quick charge for up to an hour of playback is the kind of feature that saves you on the way out the door.
Around that core, Sony stacks the practical stuff. Bluetooth 5.3 with a 10-meter range, multipoint so you can stay paired to two devices and let the buds jump to whichever one is ringing, Ambient Sound Mode with Voice Focus to keep voices audible while suppressing other noise, a built-in microphone with a wind-noise-reduction structure, an IPX4 splash-and-sweat rating, and DSEE to upscale compressed streaming audio. There's also app-based EQ via Sony's Headphones Connect app, touch controls, and a small cylindrical charging case with a tactile pattern, offered in a choice of colors with a white option as the one detailed here.
JVC Nearphones Pearl: Who It's For
The JVC Nearphones Pearl takes the opposite approach. These are open-ear earcuffs: the bud rests against your ear rather than inside it, held by arms that open like a clip and softly grip your ear. If you've ever pulled out an in-ear bud after an hour and felt that pressure, this is the design built to avoid it. JVC's own framing is "forget you're wearing earbuds," and the open architecture is also why the sound stays accompanied by the world around you — you hear traffic, colleagues and announcements without pausing your music.
The style angle is explicit here. Pearl-like sheen, a shiny arch and a compact charging case meant to read as part of your outfit rather than a gadget, in three refined colors with the Eternal Blue finish detailed on this sheet. On the practical side, JVC lists 24 hours of battery life, Bluetooth 5.3 with a 10-meter range, multipoint, a low-latency mode, IPX4 splash proofing, single-ear use, auto on/off connection, a smartphone app and button controls.
Who should buy it: runners, cyclists, office workers and anyone who wants music without sealing off their ears, plus buyers who care about the earcuff look. The sheet also calls out stability "for sports or heavy workout," and the clip-style arms are the mechanism behind that claim. Who should skip it: anyone who wants the passive noise blocking of an in-ear seal, or who prefers touch controls — these are button-operated, and the app is where you go for finer adjustments. Note that the 16-ohm impedance and 20 Hz–20 kHz range are similar on paper to the Sony, but an open-ear fit delivers sound differently, so don't expect a like-for-like listening experience.
• Best for long single-charge sessions → Sony WF-C510. Up to 11 hours per charge is a strong figure, and the case extends it to about 22 hours total.
• Best for all-day total battery → JVC Nearphones Pearl. JVC lists 24 hours of battery life, so it edges ahead on the headline number.
• Best for quick top-ups → Sony WF-C510. Five minutes in the case buys up to an hour of playback; the JVC sheet doesn't detail a quick-charge figure.
• Best for staying aware of your surroundings → JVC Nearphones Pearl. Open-ear earcuffs leave your canal unblocked; the Sony relies on an Ambient Sound Mode that you switch on.
• Best for calls and voice clarity → Sony WF-C510. The sheet specifically calls out a high-quality built-in mic, a wind-noise-reduction structure and Voice Focus for human voices.
• Best for workouts and sweaty sessions → JVC Nearphones Pearl. Both carry IPX4, but JVC explicitly frames its clip-fit stability around sports and heavy workouts.
• Best for a fashion-first look → JVC Nearphones Pearl. Pearl-like sheen, shiny arch and a case designed to match your outfit; the Sony goes the other way with a minimalist cylindrical case.
• Best for audio tweaking → Sony WF-C510. App-based EQ plus DSEE processing for compressed files gives you more ways to shape the sound.
• Best for one-ear-at-a-time use → JVC Nearphones Pearl. Single-ear use is a listed feature, handy for calls and awareness.
If I had to pick one, I'd buy the Sony WF-C510. In my opinion, it's the more complete everyday earbud: the 11-hour single-charge figure and the 5-minute quick charge are the two specs I'd actually feel every day, and the multipoint, mic, Ambient Sound Mode and app EQ round it into a dependable all-rounder rather than a one-trick design. I'd steer you to the JVC Nearphones Pearl instead if your priority is an open ear and a distinctive earcuff look — that's a real, legitimate reason to choose it, and it's the one thing the Sony simply can't do. Decide on the fit philosophy first: sealed in-ear versus open earcuff. Everything else follows from there.
Neither is better in the abstract — they solve different problems. The Sony is a sealed in-ear bud with up to 22 hours of total battery and a quick charge; the JVC is an open-ear earcuff with 24 hours of battery and full awareness of your surroundings. Pick based on whether you want your ears blocked or open.
No. Its open-ear design leaves your ear canal unblocked, and the sheet lists noise control as none. That's the point of the product: you hear your music and the world at the same time. The Sony WF-C510 also lists no active noise cancellation, but it does offer an Ambient Sound Mode you can activate.
Both are rated IPX4, so splashes and sweat are covered. JVC specifically advertises stability for sports and heavy workouts via its clip-style arms, which makes the Nearphones Pearl the more natural fit for high-movement training. The Sony's compact in-ear fit is fine for general exercise.
Both are affordable everyday options, but I can't quote figures here — pricing changes too often. Use the price button on this page to check the current price on Amazon for each, then weigh it against the specs above: the Sony wins on quick charging and call clarity, the JVC on total battery and open-ear comfort.
