In short
Get Sony LinkBuds Fit for noise cancelling and LDAC in a sealed 4.9-gram earbud that stays connected to two devices at once. Sony rates it for up to 5.5 hours of music with noise cancelling on, or 8 with it off, and it's IPX4 drip-resistant. Skip it if you'd rather keep your ears open, which is what LinkBuds Open is for, or if you want wireless charging.
Who it is for
- People who switch between a phone and a laptop. Fit stays connected to two devices at once, works across Android, iPhone and PC, and sets up with Google Fast Pair or Microsoft Swift Pair.
- Owners of LDAC-capable phones. Fit supports LDAC alongside SBC, AAC and LC3, and DSEE Extreme can upscale compressed music to up to 96 kHz, 24-bit.
- Anyone who wants noise cancelling and hear-through in one pair. Fit has Auto NC Optimizer and an Ambient Sound mode that can switch on automatically.
Who should skip it
- Anyone who wants open-ear listening. Fit seals your ears; LinkBuds Open leaves them open, without noise cancelling or LDAC.
- Buyers on a tighter budget who only need SBC and AAC. That's Sony's C-series, such as the C710N and C510.
- Anyone looking for hearing-aid or hearing-test features, which Sony doesn't list for Fit.
What sets it apart
- Shallow earpieces for a lighter seal, alongside LinkBuds Fit's fitting supporters; each bud weighs about 4.9 g with M earpieces.
- An 8.4 mm driver with Dynamic Driver X and Integrated Processor V2, names Sony also uses for WF-1000XM5's hardware.
- SBC, AAC, LDAC and LC3, with LE Audio profiles and DSEE Extreme upscaling.
- 360 Reality Audio certification, with personal optimization and head tracking.
- Wide Area Tap: taps on your face around the ear work as controls.
Caveats
- Battery figures cover the buds alone: up to 5.5 hours of music with noise cancelling on. Sony gives no total with the case, so you can't tell how many recharges it holds.
- Charging is USB-only, through the case. Sony lists no wireless charging and no quick-charge time.
- IPX4 covers drips, not swimming.

LinkBuds Fit is the LinkBuds that seals. Shallow earpieces close off your ear canal, with Fit’s own fitting supporters alongside, and that’s the split from LinkBuds Open, which leaves the canal open and has no noise cancelling.
Noise cancelling and Ambient Sound
Sony calls the noise cancelling high-performance and pairs it with Auto NC Optimizer and a structure that reduces wind noise. Adaptive Sound Control reacts to your listening environment, and Ambient Sound, which Sony calls the best in any of its true wireless earbuds, can switch on by itself.
Sound and codecs
An 8.4 mm driver uses Sony’s Dynamic Driver X, and Integrated Processor V2 runs it; Sony uses the same names for WF-1000XM5’s hardware. Fit doesn’t get the QN3e processor from Sony’s XM6. Sony’s C-series earbuds use 5 mm drivers, and LinkBuds Open an 11 mm one.
Fit supports SBC, AAC, LDAC and LC3. DSEE Extreme, switched on in the Sound Connect app, upscales compressed SBC, AAC or LDAC music to up to 96 kHz, 24-bit. Fit is also certified for 360 Reality Audio, with personal optimization and head tracking.
Battery and charging
| Mode | NC on | NC off |
|---|---|---|
| Music | Up to 5.5 hours | Up to 8 hours |
| Talk | Up to 4 hours | Up to 4 hours |
| Standby | Up to 6.5 hours | Up to 14 hours |
| With case | Not published | Not published |
Turning noise cancelling off adds two and a half hours of music. The case charges over USB, and the cable comes in the box.
Controls and calls
You don’t have to find the bud to tap it: Wide Area Tap covers the face around your ear. Quick Access is built in, wear detection pauses playback when you take a bud out, and Head Gesture answers calls. For the calls themselves, Sony describes AI-based, high-precision voice pickup.
Phones and apps
Fit runs Bluetooth 5.3 with a range of up to 10 m and supports LE Audio, Find Device and Audio Switch on top of two-device pairing. Settings, Adaptive Sound Control and DSEE Extreme live in Sony’s Sound Connect app.
Price in Japan
Sony sells LinkBuds Fit in Japan at an open price, so stores set their own. Sony Store Japan charges ¥29,700 including tax, with a 3-year warranty and same-day shipping. There’s no US launch price to compare with, so check what US retailers charge before you buy. Colors are black, white, green and pink, and the box has a USB cable, earpieces and a warranty card.

Frequently asked questions
Should I get LinkBuds Fit or LinkBuds Open?

Does LinkBuds Fit work with an iPhone?
Yes. Sony says it pairs across Android phones, iPhones and PCs, and it can stay connected to two devices at once.
Is LinkBuds Fit waterproof?
No. It's IPX4 drip-resistant, which isn't a rating for swimming.
How long does LinkBuds Fit last on a charge?
Up to 5.5 hours of music with noise cancelling on, or 8 hours with it off, and up to 4 hours of calls either way.
