”If you’re after a more affordable pair of true wireless buds with good sound, extensive smarts and impressive noise cancellation, the LinkBuds S tick those boxes.” ’Trusted Reviews’ – Recommended.

The world’s smallest and lightest*

The Sony WF-LS900N are the world’s smallest and lightest, noise-cancelling, Hi-Res, Truly wireless headphones. At just 4.8 grammes in weight, you’ll hardly even notice you’re wearing them.

* As of March 30th 2022. According to research by Sony Corporation, measured using Strategy Analytics guidelines in the Truly Wireless style supporting noise cancelling and compatible with LDAC headphones market. LDAC is a certificated codec of "Hi-Res Audio Wireless"

Comfortable fit
More than just small and light, these Sony LinkBuds S headphones are supremely comfortable, too. Using ear-shape data collected since 1982, Sony are in the best positon to design the most ergonomically optimised and comfortable in-ear headphones, for the greatest variety of ear shapes.

Automatically switches between ambient sound and noise-cancelling
The WFLS900N headphones intuitively switch between Ambient Sound Mode and noise cancelling, depending on where you are. Adaptive Sound Control detects whether you’re walking, traveling or stationary and then adjusts the ambient sound settings to suit – automatically.

Crystal-clear sound quality
Although small, the advanced, 5mm speaker drivers deliver a rich, powerful sound with articulate vocals and a crisp top-end. Coupled with the noise cancelation, you’ll hear finer details that would otherwise be hard to detect.

The best sound - wirelessly
With their LDAC wireless audio system, these Sony Bluetooth headphones are able to receive around three times more detail than ordinary Bluetooth headphones. This means that all your High-Resolution music files are played to perfection, without the need for a cabled connection.

Clearer calls
Using microphones on the inside and outside of the earbud, combined with advanced signal processing, your voice comes across loud and clear to your caller. The smart noise reduction system uses sophisticated AI machine learning to suppress ambient noise and lets you be clearly heard – even in noisy environments.

Multipoint connection
For total convenience, these Bluetooth headphones can be paired with two Bluetooth devices at the same time. So when a call comes in, your headphones know which device is ringing and connect to the right one automatically. You’ll also be able to quickly switch your headphones to either of the two devices at the touch of a button.

Speak-to-Chat and smart playback
Speak-to-Chat automatically pauses the music when you start a conversion – such as ordering a coffee – so you don’t have to remove your headphones. When you do remove them, a proximity sensor knows when you’re wearing one or none and stops the music accordingly. Pop these Sony Bluetooth earbuds back in and the music resumes.

Intuitive touch control
It’s easy to keep control of your Sony wireless earbuds, with simple touch control. Tap on the left earphone to change from noise cancellation to Ambient Sound settings, for example. The right earphone responds by skipping tracks.

Long battery life and quick charge
With 6 hours of battery life, these Sony LinkBuds last the distance. Once you’ve used up the batteries, simply pop them in their case and dip into a further 14 hours playback, giving a total of up to 20 hours. Forgotten to charge your headphones the night before? Don’t fret, as a quick 5 minute charge is all you need for 60 minutes playback.

The ideal partner for your workout
Not only do these LinkBuds fit securely, the IPX4 rating means that they’re also resistant to splashes and sweat. This makes them ideal for jogging or your regular workout.

Enjoy big sound from the smallest around, with the game-changing Sony WF-LS900N LinkBuds S earphones.

Rated 5 out of 5 by from Good value Bought as a Christmas present. These headphones are comfortable with great noise cancelling capabilities. Sound is very good and the time of use on a single charge is about 6 hours. Compared to others they are very good value

Rated 1 out of 5 by from Registering product Appalling process to register takes forever to find serial number which is not required anyway. Fitting in anything other than current date as purchase date does not work Based on simply the process or registering the product I would not recommend any Sony product to anyone.

Rated 5 out of 5 by from Amazing sound quality These tiny earbuds are easily the equal of the wf1000xm4 earbuds minus the noise cancellation. I love these especially in Earth blue. They are so comfortable, I fell asleep with them still in my ears whilst listening to music. So far I cannot find a single negative thing about them

Rated 4 out of 5 by from Battery life - I thought it would last longer Bought this 2 weeks ago. I like the design. I like the options available in the Sony Headphones app. Love the multi-point connection. The fit is excellent - I swapped out the ear buds for a larger size but switched back to those that came pre-fitted. The noise-cancelling is perfect for me as someone who works at home a lot. It reduces a lot of the background noise so that I can hear my playing music clearly, or hear speakers crystal clear during online meetings. I like the fact that it gives a quick charge when in the case - which is very handy because... Downside: battery. Unfortunately, from 100%, it doesn't last as long as mentioned in large print on the marketing blurb: "20 hours battery life with a 5 minute quick charge for up to 60 minutes of play time". It barely gets me to 1pm from a 9am start. That means I have had to switch back to using my CH-700 headphones. Those last the entire day - and more besides. Yes the CH-700 is bigger so the battery is also bigger, but seeing as I purchased the LinkBuds S based on the "20hrs battery life", let's just say I'm not a little disappointed.

Rated 3 out of 5 by from Great buds but… I was really excited about these when I received them but the excitement did not last long. The features like adaptive noise cancellation, speak to chat were spot on. However noise cancelling is not the best in these earbuds but the mic clarity was good but some complained they could hear noise. As I said earlier the excitement didn’t last for long as the left earbud stopped working within 4 days of use and I had to send it back to the Sony service centre for warranty. I’m still waiting to hear back from them with an update.

Rated 5 out of 5 by from Very good sound, very light and comfortable This is my second pair of ANC in-ear headphones. Sony are better in terms the ANC, and really good with the transparent (ambient) mode. I had to return my previous in-ear headphones (another good quality brand) because they were not staying long in my ears and the connection with Windows was not stable. In contrast Sony Linkbuds have very stable and reliable connection with my laptop and with my phone. I am very happy with the ease with which I can switch between the devices I had paired them with, and with this I do not miss the multipoint feature at all. The left one is sliding off my ear some times after longer walk and may need to readjust, but so far the fit and the stability in my ears is much better than my previous experience. The main area I would strongly advise Sony to improve is the app and the opportunity to better adjust the touch controls for the Linkbuds S. The current available touch controls are very limited and one very important for me - the return to previous track (or in my case 30s back on Audible) is possible to be assigned only as 3 taps on the right bud and tapping 3 times often gets 4 or only 2 and is not best.

Rated 5 out of 5 by from Great Sounding Earphones I have used Sony Products before, The Linkbud S has exciting sound quality and with some EQ tweaks, can make your music sound amazingly well balanced. The ANC is really good, compared to WF1000 XM4, is really close, great for traveling. The confort is really nice and compact, great for users with small to middle sized ears.

Rated 2 out of 5 by from Device linking POOR, Sound quality GREAT Researched the best earbuds for a while before opting for Sony. Bought this a month ago and they linked immediately to my mobile. Great start, but I'm unable to link to my laptop without completely disconnecting from my mobile each time. It's so frustrating, that I think it was a waste of time buying them. Sure, the sound quality is great, but I want the ability to switch between a number of devices, such as mobile, laptop, smart speaker, and completely unable to find if this possible via YouTube or Sony. Very disappointing, for a decent product.

Rated 1 out of 5 by from Confusing touch controls that don't work Had these buds for about three days now, great sound, a bit plastic feeling. They worked great initially, but now the touch controls don't work at and I have to use Google assistant the stop, change volume, skip tracks etc. Feeling disappointed as they the sound fantastic, which doesn't count for much without the controls. Oh and the app although it has lots of functionality is not very intuitive. I am going to pursue a refund

Rated 5 out of 5 by from Great everyday headphones Really loving my Linkbuds S!!! The noise cancelling is really good, and i really appreciate the 1 tap to go to ambient listening when it's busy out and about. Also best thing is how well they fit, never fallen out, even when taking a jumper off etc they stay on. Honestly such a game changer.

Rated 4 out of 5 by from Convenient but Sound could be even better Excited to buy this product following good online reviews. Being fully wireless provides great flexibility of use and relatively easy to use. Little disappointed in available functionality e.g. no volume control and sound quality and noise cancelling are not as good as some other wired buds on the market.

Rated 5 out of 5 by from Great buds Bought these iin July. Use them in work, the sound is excellent, the noise cancelling is really impressive plus the hearthrough is great. For training they are the perfect size. No chance of them falling out whilst your training. Other earbuds that I have previously bought, after a while, I would have to keep adjusting them, but the Sony linkbuds s are brilliant.

Rated 5 out of 5 by from Great all-round! Got these recently after reading/watching several reviews - I was impressed by how small the case is and how light it is, along with the buds themselves. They block a lot of noise passively and the ANC really performs well, not needing much volume to block it completely. On first try, I used these for approximately 3 hours with no ear fatigue at all, which was great. The product also has a nice matte feel, but I am definitely in the market for a protective case as I will have these on the go. I'm yet to experience any scenarios where these have slipped out of my ears and the side-profile is very low. The app is OK, but not user friendly enough in a way that's streamlined. This would be my only drawback although this is a separate part of the product itself in my opinion.

Rated 4 out of 5 by from Very pleased Purchased Linkbuds Sfrom a duty free shop At Malaga Airport, very pleased with the sound quality and ergonomics of the case and buds. Found the setting up and the lack of written instructions in the box a definite handicap being from an older generation but stumbled my way through it once I realised that I needed to down load an app and proceed from there. Overall very good.

Rated 5 out of 5 by from Small, comfortable, good sound with effective ANC I own other (older) Sony earbuds (the earliest bt in ears, WF-1000X and a neckband WI-1000X) and these are far better in terms of sound and usability than the early bt earbuds. The headphone app works well - indeed it is essential to make the most out of these. Initial hardware update worked seamlessly via the app. The app also determines how to set up the touch choices. (One thing I have not found yet are preset eq settings for types of venues). Sound is full but also clear, although you need to have ensured a good ear fit. Not difficult but needs time. This also keeps them secure in-ear. I am still trying out the many features. Speech control I have switched off as it activates too soon for non speech sounds, but being able to regulate ambient sounds is perfect for when you need to hear traffic for example. ANC is not as closed-off as my neck bands but still effective. Their small size and weight is amazing and makes for comfortable use. The case fits (hides) easily in a pocket. Battery life seems to be OK but longer usage will need a recharge from the small, neat case (as some press reviewers have said, wireless charging of case would have been good but is not available). Overall I am pleased with them. If discounted later in the year they will be even more desirable. Bought from Richer Sounds by phone using Private Eye code and arrived next day (suggested delivery time was 5 days). Very pleased with phone sale team.
