If you want tiny, sweat-resistant true wireless earbuds you can wear through a full week of commutes for very little money, choose JLab Go Air Pop; if you need long battery life, on-ear comfort and multipoint switching for work and travel, choose Sony WH-CH520.
• JLab Go Air Pop — biggest strength: a genuinely pocketable true wireless design with 9+ hours per bud, a charging case that pushes you past a full workweek, IPX4 sweat resistance and EQ3 sound tuning.
• JLab Go Air Pop — biggest trade-off: in-ear buds mean sound isolation only, no active noise cancellation, and the tiny form factor won't suit anyone who dislikes things sitting inside their ear canal.
• Sony WH-CH520 — biggest strength: up to 50 hours of battery life with quick charging, multipoint pairing for two devices at once, and a lightweight on-ear build with swivel earcups you can wear all day.
• Sony WH-CH520 — biggest trade-off: on-ear headphones are bulkier than earbuds, there's no headphone jack, and the plastic build is functional rather than premium.
• Who each pick is for: JLab Go Air Pop suits gym-goers, runners and commuters who want minimal bulk and full freedom of movement; Sony WH-CH520 suits desk workers, students and travellers who want one pair to last days between charges and hop between laptop and phone.
The Go Air Pop is a true wireless in-ear design, and everything about it is built around being small and out of the way. Each bud runs 9+ hours, and the USB-C charging case adds more on top for a total that comfortably covers a workweek of commuting. For anyone who charges their earbuds on a Sunday night and forgets about them until Thursday, that's the whole pitch.
The feature set is more thoughtful than the size suggests. EQ3 gives you three sound signatures — Signature, Bass Boost and Balanced — so you can push low end for the gym and flatten things out for podcasts. Bluetooth 5.3 handles the connection to iOS, Android and PC, and Dual Connect lets you run either earbud on its own, which is genuinely useful if you take a lot of calls and want one ear open. Each bud has a MEMS microphone, there's voice assistant access built in, and the JLab App lets you adjust EQ and remap the touch controls.
Fit is the other half of the story. These buds are 15% smaller than the previous generation and ship with three gel tip sizes, so you can actually dial in a seal. IPX4 means sweat and light rain are fine — that's the rating for workouts and drizzly walks, not swimming. Buy these if you want something that disappears in your pocket, survives a run, and lets you use one bud at a time. Skip them if you want active noise cancellation for flights, or you simply don't get along with in-ear tips.
The WH-CH520 is an on-ear wireless headphone, and its headline number is battery: up to 50 hours, with quick charging that gives you a meaningful chunk of playback from just a few minutes plugged in. That's the kind of figure that changes how you use a product — you stop thinking about charging entirely on a multi-day trip or a long festival weekend.
The rest of the design is about all-day wearability. It's lightweight, with soft ear pads, an adjustable headband, an extra head cushion and swivel earcups so the whole thing folds flat and slips on and off easily. Sound is customisable through EQ Custom in the Sony Headphones Connect app, and DSEE upscales compressed files for cleaner streaming. There's a built-in microphone for hands-free calls, and multipoint connection lets you pair two devices at once and jump from a video on your laptop to a call on your phone without repairing.
A few practical extras round it out: voice assistant activation, the ability to locate misplaced headphones via a device-finding app, a USB-C cable in the box, and six colour options. Buy these if you want one pair for work, study and travel, you like the on-ear feel, and you value switching between two devices. Skip them if you need something for sweaty workouts, want noise cancellation, or prefer the total isolation of in-ear buds.
Side-by-Side: Which Should You Choose?
• Best for battery life → Sony WH-CH520. Up to 50 hours versus a 9+ hour per-bud figure with a case top-up on the JLab.
• Best for commuting in a pocket → JLab Go Air Pop. True wireless buds and a case take up a fraction of the space of on-ear headphones.
• Best for switching between laptop and phone → Sony WH-CH520. Multipoint pairing handles two devices at once; the JLab connects one at a time.
• Best for long listening sessions → Sony WH-CH520. Lightweight on-ear build, soft pads, head cushion and swivel joints made for hours of wear.
• Best for taking calls with one ear free → JLab Go Air Pop. Dual Connect lets you use either bud independently.
• Best for sound tuning on the fly → a tie, with different tools. JLab uses EQ3 presets in the JLab App; Sony uses EQ Custom in the Headphones Connect app.
• Best for durability coverage → JLab Go Air Pop. It carries a two-year JLab warranty against Sony's one-year warranty.
If I had to pick one for myself, I'd take the Sony WH-CH520. The combination of up to 50 hours of battery, multipoint switching and an on-ear build I can wear for a full working day covers more of my actual life than a pair of buds does — and I'd rather charge something once a week than think about it daily. That said, this is genuinely a use-case decision, not a quality one. If your listening happens in the gym, on runs or on a crowded train with one bud in, the JLab Go Air Pop is the smarter buy, and its two-year warranty is a nice bit of reassurance. Check the current price on Amazon for both before you commit — the gap between them moves, and it should factor into your call.
Sony, clearly. The WH-CH520 is rated for up to 50 hours of playback with quick charging on top. The JLab Go Air Pop gives you 9+ hours per earbud plus extra from the charging case, which is strong for true wireless but still well behind.
No true active noise cancellation in the way over-ear flagships do. The listing references noise cancelling, but the practical takeaway is that these are on-ear headphones with passive isolation from the pads. The JLab Go Air Pop relies on in-ear sound isolation instead.
Yes — that's their strongest use case. They're IPX4 rated for sweat and light rain, they're 15% smaller than the previous generation, and they come with three gel tip sizes so you can get a secure fit for movement.
Both have built-in microphones for hands-free calling, so it comes down to how you work. The Sony's multipoint connection makes it easier to bounce between a laptop and a phone, while the JLab's Dual Connect lets you keep one ear free during a call.
