In short
Choose LinkBuds S over LinkBuds Fit for longer battery and a lower Sony Store price; Fit's gains are the V2 chip and a bigger 8.4 mm driver. The 4.8 g buds cancel noise, stream LDAC and LC3, connect to two devices at once and are IPX4. Sony rates them for 6 hours with noise cancelling on, 9 off and 20 with the case. Skip them if you want wireless charging or open-ear buds.
Who it is for
- Commuters who want small, light noise-cancelling buds that switch between noise cancelling and Ambient Sound on their own.
- Listeners who want LDAC and LE Audio in one small pair.
- People who juggle a phone and a PC. Multipoint holds both connections, and Swift Pair speeds up pairing with the PC.
- Shoppers who care what their gadgets are made of. The Earth Blue finish uses recycled material from collected water-server bottles.
Who should skip it
- Buyers who want Sony's newer sealed LinkBuds. LinkBuds Fit moves to the V2 chip, an 8.4 mm driver and Bluetooth 5.3, at the cost of some battery.
- Open-ear listeners. LinkBuds Open is Sony's open-ear model.
- Anyone who wants to drop the case on a wireless charger. It charges over USB-C only.
What sets it apart
- Longer battery than LinkBuds Fit: up to 6 hours with noise cancelling on and 9 off, against 5.5 and 8.
- Light buds at 4.8 g each.
- Integrated Processor V1, the chip Sony also uses in WF-1000XM4, behind the noise cancelling and Ambient Sound.
Caveats
- Talk time is 3.5 hours, with noise cancelling on or off.
- Sony gives no case weight or size, and no figure for what a quick charge buys.

LinkBuds S or LinkBuds Fit?
LinkBuds Fit is the newer sealed LinkBuds, and Sony’s Japanese store sells both. Here’s how they differ:
| Spec | LinkBuds S | LinkBuds Fit |
|---|---|---|
| Processor | Integrated Processor V1 | V2 |
| Driver | 5 mm | 8.4 mm |
| Bluetooth | 5.2 | 5.3 |
| Music, noise cancelling on | Up to 6 hours | Up to 5.5 hours |
| Music, noise cancelling off | Up to 9 hours | Up to 8 hours |
| With the case | Up to 20 hours (noise cancelling on) | No figure from Sony |
| Sony Store Japan | ¥26,400 | ¥29,700 |
Fit moves from the XM4-era V1 chip to V2 and from a 5 mm driver to 8.4 mm. LinkBuds S plays half an hour to an hour longer per charge, depending on noise cancelling, and costs less at Sony’s own store. Pick Fit for the newer hardware and S for battery and price. If you’d rather keep your ears open, LinkBuds Open is the other route.
Noise cancelling and Ambient Sound
The noise cancelling runs on Integrated Processor V1 and gets help from a structure Sony designed to cut wind noise. Ambient Sound lets in more outside sound than an earlier Sony model did, Sony says, and Adaptive Sound Control flips between the two modes based on what you’re doing and the places you go often. DSEE Extreme is a switch in the Sound Connect app.
Sony pitches LinkBuds S as suited to spatial audio but lists no 360 Reality Audio certification.
Charging
Sony’s 20-hour figure counts recharges from the case and was measured over AAC with DSEE Extreme and EQ off. On standby the buds last up to 8.5 hours with noise cancelling on, or 16 with it off. The case charges over USB-C, with a USB-A to USB-C cable in the box.
Fit and controls
The hybrid tips come in SS, S, M and LL, two pairs of each, and a fit test helps you settle on a size. Sony describes an ergonomic surface design. Quick Access is built in, wear detection pauses playback when you take a bud out, and you can listen with a single bud. The buds carry an IPX4 drip-resistance rating, which Sony qualifies with an asterisk.
Connections and calls
Bluetooth 5.2 is Power Class 1, with a range of about 10 m, and alongside LDAC and LC3 it carries the TMAP, CSIP, MCP, VCP and CCP profiles that LE Audio uses. Find Device is built in. For calls, MEMS omnidirectional microphones handle what Sony calls high-precision voice pickup.
Price and colors
Sony gives LinkBuds S no list price in Japan, where it’s sold at an open price, and Sony Store Japan charged ¥26,400 including tax on 19 September 2026. There’s no US price from Sony, so check what US retailers charge before you buy.
It comes in white, black, ecru and earth blue. The Earth Blue pair uses recycled material from collected water-server bottles in the buds and case, and the other colors use some recycled material in the exterior.
