Sony WFLS910NV.UC
The 8.4mm Dynamic Driver X and Integrated Processor V2 deliver wide-frequency sound and adaptive noise canceling that adjusts in real time, with LDAC support for Hi-Res audio. The 5g earbuds with Air Fitting Supporters stay secure during exercise, and the 5.5-hour battery plus 21-hour case, with a 5-minute quick charge for an hour of playback, covers long days. Best for active listeners who prioritize comfort and call clarity over budget, given its weakest score in affordability.
Snapshot
The 30-Second Version
The Sony LinkBuds Fit are the comfiest true wireless earbuds we've tested, with sound quality that punches above their price. ANC is strong but not flawless, and battery life is mediocre at 5.5 hours. Worth it if comfort is your top priority, skip if you need all-day battery.
Pros & Cons
Pros
- Exceptional comfort with the Air Fitting Supporters, seriously all-day wearable 98th
- Crisp, balanced sound with LDAC and customizable EQ 98th
- ANC processing borrowed from the flagship XM5 is genuinely strong 98th
- Compact case with quick charge that actually matters 93rd
Cons
- Battery life is underwhelming at 5.5 hours with ANC on
- Touch controls can be frustratingly unreliable
- Price is steep for what you get
- Wings may be too small for larger ears

The proof
Performance
The 8.4mm Dynamic Driver X delivers a wide, detailed soundstage that handles everything from bass-heavy tracks to acoustic sets without breaking a sweat. LDAC support means you're getting Hi-Res audio over Bluetooth, and the 360 Reality Audio adds a fun spatial layer if you're into that. ANC is top-tier on paper, and in our testing it's genuinely impressive, but it's not flawless. Some users report a faint hiss when ANC kicks in hard, and the adaptive mode can occasionally overcorrect in noisy environments. Battery life is the weak link here: 5.5 hours per charge with ANC on is fine, not great, and the 21-hour total from the case is middle of the pack. The 5-minute quick charge giving you an hour of playback is a nice save, though.

vs Competition
Against the Technics EAH-AZ100, the LinkBuds Fit hold their own on comfort but fall behind on battery and overall polish. The Samsung Galaxy Buds3 Pro offer better integration if you're on Android, and their ANC is arguably more consistent. Apple's AirPods Pro 3rd Gen remain the default choice for iPhone users, with better transparency mode and call quality. The JLab JBuds Pods ANC are the budget wildcard here, they can't touch the Sony's sound or ANC, but they cost a fraction of the price. The LinkBuds Fit carve out a niche: they're the comfiest of the bunch, full stop.

Price
Value & Pricing
At $198, the LinkBuds Fit are asking a lot. You're paying for comfort and processing power, not battery life or build materials. The Technics EAH-AZ100 and Samsung Galaxy Buds3 Pro both offer comparable or better ANC at similar or lower prices, and the JLab JBuds Pods ANC undercut this by a mile. If comfort is your number one priority and you're already in the Sony ecosystem, the premium might be worth it. For everyone else, it's a harder sell.

Overview
Sony's LinkBuds Fit are the comfiest earbuds we've tested in a long while. The Air Fitting Supporters do exactly what the name suggests, they lock these things in place without making your ears feel like they're being punished. You get the same Integrated Processor V2 from the flagship WF-1000XM5, which means ANC that adapts to your surroundings on the fly.
Sound is crisp and balanced out of the box, and the Sound Connect app gives you plenty of EQ room to make it yours. The catch? You're paying a premium for that comfort and processing power. At around $198, these sit in a weird spot where they're not quite flagship money, but they're definitely not budget buds either.
Common Questions
Q: Do the LinkBuds Fit stay in place during exercise?
Yes, the Air Fitting Supporters are designed specifically for this. Most owners report they stay secure during runs and workouts, though a few with larger ears found the wings too small.
Q: How does the ANC compare to the WF-1000XM5?
It uses the same Integrated Processor V2, so the ANC is very close in quality. However, some users report a slight hiss at higher ANC levels that isn't present on the XM5.
Q: Is the battery life enough for a full day?
Not quite. You get 5.5 hours per charge with ANC on, plus another 15.5 hours from the case. The 5-minute quick charge adds about an hour of playback, which helps in a pinch.
Who Should Skip This
If you need all-day battery life without reaching for the case, look elsewhere. The 5.5-hour earbud battery is a real limitation for long flights or marathon work sessions. Also skip these if you have larger ears, the wings may not fit securely, and if you rely heavily on touch controls, the inconsistent response will drive you nuts.
Verdict
If you've struggled to find earbuds that stay put during workouts or long commutes, the LinkBuds Fit are worth a serious look. The comfort is genuinely best-in-class, and the sound quality backs it up. Just know you're trading battery life and touch control reliability for that fit. Buy them for the comfort, stay for the sound, and keep the charging case handy.
