TechRadar Verdict
The Sony WH-CH720N pack in a lot of audio finesse and smart features for the price. Unlike Sony’s mid-range earbuds, they’re not stealing flagship-like performance from the gods – there are clear limitations compared to step-up models – but they’re a comfortable, enjoyable listen, and the ANC does a good job of lowering outside noise.

The newSonyWH-CH720N noise-cancelling headphones are a direct replacement for the previous CH710N model, adding new features, plus sound and noise-cancelling upgrades.
With an official price of $129 / £99 / AU$259, the Sony WH-CH720N are aggressively positioned, bringing some flagship-level features from thebest noise-cancelling headphonesto lower budgets, including adaptive noise-cancellation, multi-point pairing, and app support.
But do they bring flagship-level performance too? Not quite – you’re definitely getting more in line for what you pay for here. We were blown away by what theSony WF-C700Nearbuds deliver for the price, and with these being the equivalent over-ear headphones, we hoped for the same again. But we’re less blown away, and more saying, “Oh wow, there’s a serious breeze today”. Which is absolutely fine for this price – it would have been churlish to expect them to really challenge theSony WH-1000XM5, which cost more than three times as much.
Let’s start with sound quality, since it’s really the most important element. Out of the box, I found them pretty heavy-handed when it came to bass. I didn’t hate it, but it’s not what I was expecting. However, once I connected the cans to the Sony Headphones app and looked at the settings, I realised they were on the ‘Excited’ EQ preset, which was overcooking things. After turning this off, I found they deliver a pretty much ideal balance.
Bass is warm but level-headed, mid-range is robust and individual instruments stand out within it well, and treble has plenty of clarity to make the little details pop. An extra step of precision is definitely what you get here that most other affordable headphones won’t deliver – the detail across the whole range is strong, and songs feel sharp.
They’re fun to listen to, capable of giving something some nice energy and bounce. Where they slip a little is in naturalism and their dynamic response. The sound doesn’t feel open, and it doesn’t have the ability to suddenly blow up and shift gears in the way that better headphones can – it feels like it has to stay with a certain lane, and that’s constraining it.
On the good side, it’s also a fairly relaxed presentation. Some ANC processing can make sound feel quite forward and aggressive, but that’s not the case here. I didn’t find them fatiguing to listen to at all over a whole afternoon, or for a whole flight.
That’s partly because they’re light and comfortable – at just 192g / 6.8oz, they’re far lighter than higher-end headphones, and so even though they’re less well padded than premium models, they never became sore for me.
The lightweight plastic feels a little rougher and less high-quality than what you get in even the olderSony WH-1000XM4, let alone the newer XM5, but that’s fine.
Speaking of design, you’ve got buttons on the underside of both earbuds. On the left are controls for turning them off and on, and switching ANC modes. On the right are play/pause and skip buttons. They’re all fairly easy to find under your fingers.
The active noise cancellation here is good at reducing the volume of outside sounds severely, but it’s not the massive, mind-blowing sound blocker that you get from the really elite models. It’s great for the price, though.
The noise cancellation of the CH720N effectively puts its boot down on the loud sounds of city traffic, for example. I walked along the road listening to music that I could hear clearly, and I didn’t have to crank the volume loud in order to make out what I was listening – at only about 25% volume, I could listen happily.
But standing at one intersection and switching between the CH720N, my older Sony WH-1000XM3, and my newerApple AirPods Pro 2earbuds revealed that the CH720N was leaking in traffic noise from an adjoining busy road about 200 feet away. With the XM3 or AirPods Pro 2, that road ceased to exist – as far as my ears were concerned.
Taking the CH720N on a flight was a similar story – they made it much easier to focus on the sound, but the engine drone lived on more than with higher-end gear. WatchingRye Lanewith its its gentle, conversational dialog levels, I had to crank the volume up high (over 60%) to ensure I could hear everything clearly.
The CH720N are well-equipped for features even beyond what I’ve mentioned so far. There’s support for 360 Reality Audio and Sony’s DSEE upscaling of mediocre-quality tracks (looking at you, still,Spotify), which no doubt contributes to the detailed sound.
There is no LDAC hi-res support, but the CH720N does have Bluetooth 5.2, so it could supportBluetooth LE AudioandAuracastin the future, if Sony can persuade itself to support the same next-gen standards as everyone else. The multi-point pairing works well for easy switching between devices – there can be wobbles, but nothing that trying a second time didn’t fix for me. They have a USB-C port for charging, and a 3.5mm jack, with a good-length cable in the box.
The battery life claim of 35 hours at normal listening volumes with ANC on is right in line with my experience – if anything, it’s a little low. There’s no auto-pause when you take them off, though, so just make sure you don’t run them down accidentally.
Overall, I think these rank among thebest cheap headphonesavailable today – their performance ranks really well against competition from the likes of JBL. They sound good, their noise cancelling is effective, and you get a lot of smart features. They’re great – but if you can stretch to go higher, even up to a pair of Sony WH-1000XM4, you really do get a leap forward in audio and ANC quality.
Sony WH-CH720N review: Price & release date
The Sony WH-CH720N are competitively priced at $149 / £99 / AU$259 – though the UK is most competitive out of those. Still, you don’t get many noise-cancelling headphones from big brands at that kind of price, generally. Much like their earbuds sibling, theSony WF-C700N, they somewhat over-deliver on features in general compared to most other options in this price range.
Much of the WH-CH720N’s competition is from the likes ofAnkerSoundcore or 1More, though JBL is probably the best known competitor – most notably with theJBL Tune 750BTNC, which costs pretty much the same.
Sony WH-CH720N review: Specs
Should you buy the Sony WH-CH720N?
Buy them if…
You want solid ANC for lessThey might not be magic sound silencers, but the Sony WH-CH720N are great at clamping down on the din around you and letting your music or videos come through at a normal volume – great for your hearing health.
Music quality mattersThey may not be audiophile quality, but audiophiles should appreciate what Sony is going for here: finely balanced sound that’s brimming with detail. If you want to hear your music represented well, you can’t do much better for the price.
You want a long battery lifeAt 35 hours with ANC on (and much longer with it off), these are rated to last longer than Sony’s flagship headphones.
Don’t buy them if…
You expect absolute noise-blocking powerThe ANC is great for the price, but it does leak in sound from across the spectrum.
You want hi-res audioThere’s nothing here, though with Bluetooth 5.2 support, Sony could theoretically add it in the future – but don’t bet on that.
You want expansive, naturalistic soundAs good as the sound is, it still feels restrained by the processing and limited dynamic range. If audio fidelity is your main focus, wired-only headphones at the same price will do it better (though without ANC).
Sony WH-CH720N: Also consider
Anker Soundcore Life Q30Officially priced higher than the Sony WH-CH520 (though not by much), but actually available for around the same price, the Q30 add the 3.5mm jack and active noise cancellation into the mix. They’re an excellent value, though twice the weight of the Sony.
JBL Tune 760NCThese are a lot like the Sony, but they offer a folding design, which is useful for travel – and they’re cheaper in some places. The Sony headphones offer more features, but they’re similar in a huge number of ways. The Sony feel a little more future-proof, so we’d maybe lean in that direction, but there’s not a lot in it.
How I tested the Sony WH-CH720N
For testing the Sony WH-CH720N, I mainly used them as part of my standard routine – I used them for walking around the city, I used them in the TechRadar office to drown out the wails from the dungeon, and I used them on the bus. But I also took them on a work trip that involved a longer train and then a flight, so I could really test the active noise cancellation.
I mainly listened to music fromAppleMusic on my iPhone 13 Pro, but I also used them with my laptop, streamed videoYouTubeand other sources, and watched movies fromAmazonPrime Video and Mubi.
I’ve been testing headphones and audio equipment for over a decade, ranging from affordable options such as these, up to much higher-end sets.
