USB 2.0 can support up to 480 Mbps. It’s more than fast enough for any audio stream you can send to a DAC.
Your headphones don’t need USB 3.0 5 Gbps speeds. USB 3 requires extra wires with different properties that need to be controlled more tightly, which can impact cable flexibility. If your headphones used USB 3 when they didn’t need it that would be one more thing to break and more failure modes for the cable.
A USB 2 cable with fewer conductors was the right choice for this product. The fact that you only got miffed about it when plugging the cable into a tester, not from actually using the product or cable, is good evidence that a USB 3 cable wasn’t needed.
Apple’s iPhone cables are not known for their durability. They serve a mostly stationary purpose, unlike headphones you wear on your head.
I keep a few converters for older devices and servers that don't have (m)any C ports, but as far as a consumer "forever cable" goes, TB5 feels close. Certainly the cable's bandwidth is beyond what most people need, unless you're editing 8k video or continually shuffling hundreds of GBs between external disks.
It alleviates the anxiety of knowing what cable does what.
I use Apples Thunderbolt 4 or USB-C cables exclusively: if its white its for charging and low data, if its black its for high data.
I’ve been doing this for a few years, but its really costly as those Apple Thunderbolt cables are crazy expensive.
I have one of those. They are thick and unwieldy af. Since I've borked the usb connection on my monitor because of static discharge, I no longer use it and figured I'd repurpose it for my digital camera, for which I used to have a short cable that was sometimes annoying. This cable is so freaking think and hard that it'll move my (admittedly somewhat light) camera on the table.
It’s rigid and thick, like a Thunderbolt 3 cable, yet only supports USB 2.0 speeds and fast charging for a device that doesn’t need fast charging.
Compare that to Apple’s iPhone USB-C cable which is thin, flexible, and supports the same features.
That matters because someone might grab that cable assuming it’s a “better cable”: it came with a £629 product, it’s thick and feels serious, so surely it’s capable. But it isn’t. And there’s nothing marked on it to tell you otherwise.
The whole system ends up relying on presumption, which is exactly the problem the device in the article is solving.
The purpose of the heavy construction is to make it durable, not to carry 5 Gbps data streams to your headphones.
Unlike most USB peripherals like your printer and keyboard that get plugged in and then don’t move around, headphone cables go to your head and move around constantly. They can get pinched in drawers or snagged on corners.
Hence the more durable construction.
Apple’s USB iPhone cables wearing out prematurely is so common it’s a meme.
Maybe Apple's changed their cables recently, but the fragility is the reason I avoid Apple cables.
Especially in headphones. The number of times those broke during a bike ride or run was way to high for me to keep wasting money on them knowing full well they weren't going to last more than a few months just like every other Apple headphone I've ever had.

I don’t know how to fix the market especially when consumers keep rewarding these practices, and I think the effectiveness of TikTok style influencer marketing will make it worse.
The problem is the opposite of what you’re describing, it’s not a cynical design choice, it’s a lazy one. They probably just purchased a cable for capabilities irrelevant to the product and the result is worse ergonomics and misleading physical cues about what the cable can actually do.
I think you are underestimating the importance of perceived premium combined with the pressures of cost accounting, but I do think that is pretty normal for ‘audiophiles’ which is their target market.
If the argument is that B&W deliberately chose a thick cable to seem premium, it doesn’t square with them actively slimming down the headphones. B&W are primarily a speaker company, their USB-C product range is basically just a few headphones and earbuds.
More likely they just sourced a generic cable that happened to support high wattage and didn’t think about the mismatch.
Either way, we’re deep in the weeds on B&W’s cable procurement now. The root point is that USB-C is a mess. You can’t tell what a cable supports by looking at it, and even premium manufacturers are shipping cables that don’t do what you’d reasonably expect.
That’s exactly the problem the Treedix from the article solves.
You are using circular reasoning in your logic, you assume the premise is true and from there you derive your evidence.
I would contend that someone thought about it and decided to go with the cheaper option because they could get away with it. I would consider my assumption to have more grounding given my experience with manufacturing and cost accounting.
My example of weights is that the steel weighs are cheaper than the alternative of using heavier drivers, by adding weight they are signaling premium without delivering it. Similarly with the USB cable, consumers assume such cables are thick because of thicker wires and better shielding, it’s cheaper to make a thick cable without those those features, once again signaling premium without actually providing it.
The vast majority of high volume consumer manufacturers use cost accounting practices which would absolutely be tracking and attributing the usb cable costs and the whole point of that accounting practice is to constantly be thinking about minimizing costs of even the smallest inputs, all the way down to the individual screws used. Yes, they’re thinking about how to save 1/100ths of a cent from each screw.
Or, why Apple manages the same in half the footprint?
Or, why someone would expect that a cable that came with a pair of headphones actually charges things at over 65w?
So, no: I wouldn't expect the cable for a pair of headphones (of any price) to support USB 3. That represents extra complexity (literally more wires inside) that is totally irrelevant for the product the cable was sold with. (The cables included with >$1k iPhones don't support USB 3, either.)
Meanwhile: Fast charging. All correctly-made USB C cables support at least 3 amps worth of 20 volts, or 60 Watts. This isn't an added-cost feature; it's just what the bare minimum no-emarker-inside specification requires. A 25-cent USB C-to-C cable from Temu either supports 60W of USB PD, or it is broken and defiant of USB-IF's specifications.

Now, of course: The cable could be thinner and more flexible and do these same things. That'd probably be preferred, even: Traditional analog headphones often used very deliberately thin cables with interesting construction (like using Litz wire to reduce the amount of internal plastic insulation) to improve the user's freedom of movement, and help prevent mechanical noise from the cables dragging across clothes and such from being telegraphed to the user's ears.
Using practical cabling was something that headphone makers strived to be good at doing. I'm a little bit annoyed to learn that a once-prestigious company like B&W is shipping cables with headphones that are the antithesis of what practical headphone cables should be.

But yeah, both USB C cables and the ports on devices could be better marked so we know WTF they do, to limit the amount of presumption required in the real world. So that a person can tell -- at a glance! -- what charging modes a device accepts or provides, or whether it supports video, or whether it is USB 2 or USB 3, or [...].
Prior to USB C, someone familiar with the tech could look at a device or a cable and generally succeed at visually discerning its function, but that's broadly gone with USB C. What we have instead is just an oblong hole that looks like all of the other oblong holes do.
After complaining about this occasionally since the appearance of USB C a decade or so ago, I've come to realize that most people just don't care about this -- at all. Not even a little bit. Even though these things get used by common people every day, the details are completely out of the scope of their thought processes.
It doesn't have to be this way, but it's not going to change: Unmarked ports are connected together with unmarked cables and thus unknown common capabilities are just how we roll.
Your last paragraph is depressingly accurate though. I think that's exactly why devices like the Treedix exist: the standards bodies and manufacturers clearly aren't going to fix the marking problem, so now we need test equipment to figure out what our own cables do.
