This review is just plain bad.
"Dyson smartly did away with the unpopular air purifying mask design that it used for its prior-generation "
No... just no.
Dyson made a model that doesn't have the feature that was in their first headphone model which was the whole reason they made headphones! Why are you writing about a product when you don't understand where it comes from?
Dyson started out with vacuums. They came up with a great way to reliably remove debris from the sucked in air before it hits the filter resulting in you not having to buy replacement bags. As they went on they got more and more into air filtration and air-moving technology as they made newer vacuum models. That research resulted in them making new and innovative fans and air purifiers.
They also continued to make more complicated and well-designed electric motors which are basically in nearly all their products.
Dyson's headphone line started out as a portable air purifier. They figured out the best way to make a portable air purifier was to simply mount it on the head and avoid hoses etc. Then they were like hey, that'll be noisey. So they were like how do we get rid of the noise factor? Well, you could put music in people's ears and also use noise-cancelling tech to block out the hum from the motors/fans running on each ear.
That's how you get to the Dyson Zone headphones, which are fantastic and are beloved by people who use them. Why are they beloved? Because some of us can't breathe the same air that you take for granted. I get brutal migraines when expose to amounts of perfume that you can't even smell. I have four air purifiers in a one-bedroom apartment.
The Dyson Zone are INCREDIBLY POPULAR among people who aren't ableist twits! Just because you don't need the Dyson Zone doesn't mean that it isn't filling a niche. Now, is that niche big enough to sustain a product line for a company Dyson's size? I honestly don't know, but I do know from talking to other people with my condition online, for a lot of us this has given us our lives back and enabled us to go into public spaces like grocery stores or shopping malls safely in a manner that things like an N95 mask don't. (You can check out the documentary Stink on YouTube if you want to learn a bit more about why chemicals that destroy some people are allowed in almost any soap or cleaning product you buy. I will spoil it for you, the reason is rich douche bags and lax journalism.)
For anyone who cares about the sound, the OnTracs if they sound like the Zone (which I'm sure they do) will be quite good. You don't get the spacial audio effect of the AirPods Max, but if you want really good balanced sound, great noise cancellation and you don't want to get AirPods Max, I'd say feel free to give these a go. I will say that having these automatically connect to my iPhone was sometimes a pain, I'm not sure if that was the iPhone's fault or the Dyson's, but setting up a Siri shortcut to do it makes it work generally flawlessly which makes me think it's iOS's fault.
