We've pretty much been waiting for a sequel to the Award-winning Sony WH-CH720N since they arrived in 2023.
Not because they fell short of our expectations – quite the opposite – but because the budget noise-cancelling over-ears were so good, we couldn't wait to see what Sony could do when given another chance to impress.
A sequel has indeed finally arrived in the shape of the Sony WH-CH730N, vowing to elevate everything we liked about the WH-CH720N while mitigating their modest but not-trivial limitations.
Those limitations included a slightly bass-heavy sonic signature, as well as a design that, if we're being charitable, wasn't exactly the last word in luxury.
If the WH-CH730N can rectify such minor issues without losing the character of what made their predecessors so great, they could truly be successors to some of our favourite headphones of the past few years. Now that's something worth getting excited about.
When Sony invited us for an exclusive look at the WH-CH730N, we had to take advantage. We haven't heard the new headphones yet, but we've had a sneak peek at how they look and feel, and heard directly from Sony about the changes the next-gen over-ears have made. From what we've seen, they could be something very special.
Excited for: a new folding look
When we went to see them in person a few weeks ago, we really liked the way the new WH-CH730N looked.
Taste is subjective – and how a pair of headphones appear on the outside should be a secondary priority to how they sound – but that wholesale redesign really works for us. The WH-CH720N were, to be charitable, rather rough and ready headphones, but the smoother, more modern design of their successors feels like a big improvement. Out are the rather basic earcups, replaced by larger, more premium cups that come across as far more premium than the headphones' modest price might suggest.
Better still, they should be more ergonomic to live with thanks to the fact that the new over-ears feel sturdier and are now fully foldable, something that was lacking in the somewhat rigid WH-CH720N. It was always a worry that you might accidentally snap your precious headphones in transit, but full foldability helps assuage such fears this time around.
It makes sense considering that these are still reasonably budget-friendly headphones geared towards everyday use. When you've got over-ears that are going to be thrown into backpacks and tossed into the back of the car, you want to know they're going to survive years of potentially hard use.
Excited for: refined tuning and (hopefully) better sound
At first, it was easy to hear the news that Sony hadn’t updated the physical drivers for the Sony WH-CH730N. You expect new hardware from one generation to the next, so the fact that Sony had kept the same 30mm dynamic units as found in the WH-CH720N just slightly smacked of complacency.
Yet that needn’t be the case. The thing is, the WH-CH720N sound great – they might be the best sound-per-pound wireless over-ears you can buy – with their slightly enthusiastic bass the only real point of criticism. Even then, you can tone that down via the in-app equaliser, so it’s not a huge deal.
As it turns out, we want more of the same from the WH-CH730N, albeit with a bit of sonic tinkering to make them as good as they can be. Tweaking tuning algorithms rather than physical hardware can make a surprisingly profound difference, too – just look at how much better the Bose QuietComfort Ultra Earbuds (2nd Gen) sound over their first-gen antecedents.
The punchy, deeply musical personality of the WH-CH720N…but better? Sounds like a recipe for success to us.
Excited for: longer battery life
Wow, check out these numbers. We didn’t think the WH-CH720N were exactly short on battery life, thanks to their 50 hours of lifespan with ANC off and a still-massive 35 hours with it on, but Sony has really doubled down for the sequel.
The WH-CH730N will go for 75 hours before they need a recharge if you have noise cancelling turned off, a figure that quite frankly puts their predecessors in the shade. That’s a huge usability bonus, only sweetened by the fact that a three-minute quick charge will grant around an hour of playback when you’re in a hurry.
Not many rivals come close at this kind of money. The Austrian Audio Hi-X25BT (£129 / $140) will go for around 30 hours before they need a recharge, whereas even the mega-battery-boasting Philips TAH8000E's (£140 / $149) 70 hours with ANC off can't quite keep up.
Excited for: that seamless Sony usability
From the bottom of its range to the very top, Sony's headphones are very rarely a chore to live with. Quality tends to suffuse everything the brand does at the moment, with its wireless cans exemplifying this customer-first focus on usability and performance that few rivals can match.
What the WH-CH730N have in their favour right out of the gate, then, is the fact that they're a pair of Sony over-ears. That means certain features, such as DSEE upscaling for poorer-quality files, as well as 'Precise Voice Pickup Technology' for better noise calls and beamforming mics contributing to improved noise cancelling, are already in the bank.
Plus, access to the Sony Headphones app is never a bad thing, as while it's rarely been the most sleek or stylish platform in the world, the levels of customisation it offers are extremely tough to beat.
Unless something goes horribly wrong, we'd feel confident in stating that, from its voice calls to its ANC, we'll likely be in very safe hands with the WH-CH730N.
A small concern: that higher price
This isn't a dealbreaker for most, but it's still worth mentioning: the WH-CH730N are more expensive at launch than their predecessors. It's not a massive increase – only £10 in the UK – but it does point to a slightly more worrying trend in audio concerning rising prices.
This isn't something for which we blame Sony, but more a reflection of where things could be headed across the market. Due to poor market conditions, the global economic downturn, certain political decisions and an increasing scarcity of computer chips, consumer audio prices are rising, and even the budget end of the audio landscape isn't unaffected.
£10 isn't a huge rise from one generation to the next, but when even massive entities such as Sony are affected, it could point to an unwanted trend: higher prices for your headphones.
