Sony LinkBuds Fit WFLS910N/G

The Sony LinkBuds Fit deliver flagship-level ANC in a secure, workout-friendly package, but the sound quality is a major letdown at 34.2/100. Battery life is average at 5.5 hours per charge, and the touch controls are finicky. At USD 180 to USD 230, they're worth considering for gym use and calls, but music lovers should look at the Technics EAH-AZ100 instead.

Let's start with the good news: ANC is genuinely excellent. These rank in the 97th percentile for noise cancelling, which puts them right up there with the best we've tested. The dual noise sensor tech and real-time optimization work. In a coffee shop or on a plane, these do a great job of carving out the low-end rumble and most of the midrange chatter. The adaptive ANC that adjusts based on your environment is also genuinely useful, not just a gimmick.

But here's the thing that's going to surprise a lot of people: the sound quality score is 34.2 out of 100. That's a 4th percentile ranking. For a Sony product with the Dynamic Driver X name attached, that's rough. The 5mm driver is small, and while the frequency response claims 30Hz to 20kHz, the real-world tuning leans heavily on the bass and can wash out at higher volumes, especially with ANC engaged. If you're coming from the WF-1000XM5, you'll notice the difference immediately. The LinkBuds Fit are tuned for energy and punch, not detail retrieval. For podcasts and gym playlists, that's fine. For critical listening, it's a letdown.

The Technics EAH-AZ100 is the most direct competitor here, and honestly, it's a better-sounding earbud. Technics has been nailing the tuning on their recent releases, and the AZ100 delivers more detail and balance than the LinkBuds Fit. You'll trade a bit of Sony's ANC polish for better audio, but for most people, that's a worthwhile swap.

The Apple AirPods Pro 3 are the obvious choice if you're in the Apple ecosystem. Their transparency mode is still the best in the business, and the integration with iOS is seamless. But the LinkBuds Fit beat them on ANC and offer more customization through the Sony app. The Nothing Ear (3) is another interesting option, with a more neutral sound signature and a lower price point. And if you're on a budget, the Soundcore P31i or EarFun Air Pro 4+ will get you 80% of the way there for half the money.

Pricing is all over the place right now. We're seeing these listed between USD 180 and USD 230 across four US listings, with Best Buy typically landing on the lower end of that spread. If you're in Canada, it's CAD 298 at a single retailer. That USD 50 spread is worth paying attention to. Same earbuds, same features, but one store might save you enough for a decent lunch.

At USD 180, the LinkBuds Fit make a stronger case. You're getting flagship ANC and solid connectivity for less than the WF-1000XM5. At USD 230, the value proposition gets murkier. The sound quality just doesn't justify that price when competitors are offering better audio for similar money. If you can snag these on sale or price match at the lower end, it's a much easier recommendation.

Sony's LinkBuds Fit are the company's attempt to make a workout-friendly earbud that doesn't sacrifice the smarts. You get the same Integrated Processor V2 found in the flagship WF-1000XM5, a 5mm Dynamic Driver X, and a new wing tip design meant to keep these things planted while you're moving. The pitch is simple: flagship noise cancelling and call quality in a smaller, sportier package.

Who's this for? Someone who wants Sony's ANC chops but found the XM5 too bulky or too expensive. The LinkBuds Fit sit in that middle ground where you're paying for processing power and app features more than raw audio hardware. And that's an interesting trade-off, because the sound score in our database is rough. More on that in a bit.

The Sage Green colorway we tested has a marbled pattern on the case, which is a nice touch. Sony clearly wants these to feel like a lifestyle product, not just another black earbud. And with IPX4 water resistance, they'll survive sweaty workouts and light rain. Just don't drop them in the pool.

If you're an audiophile or someone who cares about detail retrieval, instrument separation, and a balanced sound signature, skip these. The 4th percentile sound score isn't something you can fully fix with EQ. You'd be better served by the Technics EAH-AZ100, which offers better tuning at a similar price, or the Nothing Ear (3) if you want something more neutral.

Also skip these if you have smaller ears or find bulky earbuds uncomfortable. The comfort ranking in the 30th percentile is a real concern, and the wing tips, while secure, add bulk. If you're looking for something that disappears in your ear, the AirPods Pro 3 or the EarFun Air Pro 4+ are more comfortable options. And if you need all-day battery life without reaching for the case, the 5.5-hour earbud life here will frustrate you.

If you're a gym person who wants top-tier noise cancelling and doesn't care about critical listening, the LinkBuds Fit are a solid pick. The secure fit, IPX4 rating, and excellent ANC make them great workout companions. The quick charge feature is genuinely useful when you forget to top them up before a session. And the Sony app gives you enough EQ control to dial in a sound you can live with.

But if you're buying these for music first and everything else second, look elsewhere. The 4th percentile sound score isn't a fluke. These are tuned for energy and convenience, not detail. The Technics EAH-AZ100 or even the Nothing Ear (3) will serve you better if audio quality is the priority. The LinkBuds Fit are a great ANC product with a mediocre sound signature, and you need to know that going in.
