What is the Dyson Supersonic?

Dyson has already sexed up the vacuum cleaner and even the hand dryer, and now it’s turned its attention to the humble hair dryer.

The Supersonic has been four years in the making, at a cost of a cool £50 million. In excess of 600 prototypes were created on the way to the finished article, tested on more than 1,000 miles of human hair.

As a result, Dyson reckons it’s created the fastest, quietest, most hair-friendly hair dryer in existence. So will the Supersonic leave you feeling like you've just stepped out of the salon?

Dyson Supersonic – Design and Features

There’s no question that this hairdryer looks cool. It's like no hairdryer you’ve seen before. I can even forgive the fuchsia-pink accents – perhaps there in case us ladies weren’t sure it was the product for us. Urgh.

The unboxing experience isn’t your average affair, either. With a standard hair dryer, you’ll likely be hit by an avalanche of clips and attachments as you pull open the box. But as you lift the lid on the Dyson, you’ll see your hairdryer and various attachments presented neatly in their own moulded compartments.

So why is the design so different? Well, the smart bods at Dyson have created a digital motor that’s small enough that it can sit in the handle, rather than be bolted on at the back of the dryer head.

One advantage of this, ahem, ‘cutting-edge’ technology is that the Supersonic feels more balanced, so you’re less likely to get arm ache as you’re using it. And if you have hair as long and unruly as mine, that’s kind of a big deal.Dyson Supersonic

That said, it’s not lightweight. I pitted it against my existing, much bulkier hairdryer and they both weighed in at 700g, without attachments. The Supersonic is compact, though, and could easily squeeze into your hand luggage if you wanted to take it travelling.

Air is drawn into the motor, and then Dyson’s Air Multiplier technology amplifies its volume. This makes for a very fast, powerful and targeted current that’s easy to aim at whatever bit of hair you want to style. There’s also a heat-protection sensor that stops the temperature of said air ever getting high enough to damage your luscious locks.

One last feature of note is that each of the attachments is magnetic, so they snap into place at the front of the hairdryer with no effort whatsoever. There’s a Smoothing Nozzle, which dries and gives a smooth finish at the same time, and a smaller Concentrator that can be used for more precise styling. The final and largest attachment is the Diffuser for defining curls and defrizzing.

Dyson Supersonic – Performance

The Dyson Supersonic is easy enough to use. Simply slide the switch to the 'on' position, and away you go.

To adjust the heat and speed, you’ll need to tap the fan and temperature buttons at the back of the dryer. There are four levels for each, indicated by blue LEDs. I’ll admit, I did find this a little fiddly. On my existing dryer, these controls are chunky and close to my thumb, so I can change them without looking. On the Dyson, the buttons are far smaller, so you need to have a good sense of where they are.

There is, however, a button conveniently close to where your forefinger would naturally sit as you hold Dyson’s dryer. Press this when styling for a blast of cool air. I tried the Supersonic first with the Smoothing Nozzle. Rather than blowing my hair around randomly like I was stuck in a Force 10 gale, the nozzle directed the heat efficiently.

Even when I rested it right against my hair, there wasn’t a whiff of that dreaded burning smell. Nor did my ears get uncomfortably hot as I dried around them. I have a blunt fringe that likes to do its own crazy thing, but the Styling Concentrator quickly coaxed it into submission.Dyson Supersonic

But what really blew my mind was the Supersonic’s speed. I swear my hair was dry in around half the time it would usually take.

What’s more, it was visibly smoother and shinier. This meant I didn’t need to attack the frizz with the straighteners afterwards, or pile on a whole lot of finishing product.

Dyson has done a couple of things while engineering the Supersonic to make it run as quietly as possible. The first sounds relatively simple – using a rubber mount to reduce the vibration between the motor and the handle.

The second is more scientific. As James Dyson puts it, "by giving the motor impeller 13 blades instead of the usual 11, we pushed one tone within the motor to a sound frequency beyond the audible range for humans."

In reality, while the Supersonic is definitely much quieter than my existing hair dryer, it’s not the case that only dogs can hear it. The ultimate test came when I decided to dry my hair at the end of the bed where my husband was sleeping. A high-risk strategy, I’m sure you’ll agree.

He woke up. But he did drift off to sleep again almost immediately, and without pulling a pillow over his head as he might normally do. If you’re getting ready with the girls, you could certainly have a conversation over the Supersonic without having to raise your voice.

Should I buy the Dyson Supersonic?

If you really care about your 'do, then I reckon the Supersonic is a worthy buy. Its ability to smooth hair was particularly impressive. It could save you a fortune in styling products, and you might even be able to ditch your GHDs or those pricey Brazilian straightening treatments at your local salon.

But it’s the speed of this dryer that puts it a cut above the rest. Because anything that buys us an extra 10 minutes in bed is a winner in our book.


At £300, the Supersonic is hardly a snip. But if you’ve got the cash to splash, it’s well worth it to have a good-hair day, every day.

So for the price of 8 (yes 8) BaByliss AC motored hairdryers (ionic & ceramic features) with the switches in the right places and a very high quality feel and sound... you can have style over function. Top styling tip, buy 2 Babyliss hairdryers to use together and use the rest of the money you would have spent on tha Dyson to pay down your likely high debt levels.

I preordered and have been using it for a week -- replacing my ionic dryer. Yes, it's a big investment, and I'm glad I went for it. My drying time is cut down to 7 mins (from 15) and I'd describe my hair as 'bouncier' -- shinier, less frizzy, and holds the rolled-brush form better. One to two passes of the concentrated nozzle+a cold blast on each section of my shoulder length hair and I am out the door. Quieter, and the magnetic attachments are great. The cord is heavier than expected and I'm still getting used to the button positions ($499 CDN). The temperature precision and power is outstanding - it seems to dry well at lower temps and there is zero 'hair burn'. It's comfortable on the roots and touching the hair. I'm happier drying/styling more often=more good hair days. I wanted to invest in keeping my hair healthier longer. It's a beautiful piece of equipment and I enjoy using it. Probably not for everyone, but if you are a 'hair person' I'd recommend it for sure.

This is clearly aimed at the apple generation. Make it expensive and tell them it's stylish... fools will give you their money.


December 11, 2016, 4:02 pm

Bull. Total nonsense. The same dumb comment could be applied to everything - houses, cars, flights, you name it, by your reckoning anyone buying anything other than middle-of-the-road- priced goods is an idiot. I reckon you're the fool.


December 11, 2016, 4:04 pm

Yes, because everyone who can afford luxury goods must be doing so via debt. Not so, some of use have the luxury of being able to afford anything we want without giving a hoot about the cost. Get over it and get back to watching a black and white portable tv in your caravan.

Am I the only one who is completely underwhelmed by this dryer? I really, really wanted to like it, based upon the glowing testimonials and demonstrations of the thing I saw on QVC, not to mention other reviews.I heard "lifechanging" and thought, okay. I have to try it.I bought it, took it home, and gave it a shot - four times to be exact. First of all, it's not very light. I don't think the design is such a breakthrough - the motor's in the handle. Really, so what? I have very thick, semi-curly hair and I did a time comparison between how long it took me to dry it with the Dyson and my Conair 1875 and the Dyson was maybe two minutes less. The Conair is lighter and does just as good a job. I think the $399 price tag is paying for the packaging, and the two diffusers, which I don't use anyway. Hot air is hot air, and I honestly don't feel the Dyson is worth the hype or the money.

Of course this is a typical James Dyson 'I am the world's greatest inventor so you must buy my overpriced gadgets'. I am surprised that, unlike the Dyson vacuum which I bought, and quickly ditched because it was plastic junk and broke in no time, this thing isn't covered with his self-aggrandising stickers. My local electrical shop has a room devoted to broken Dyson cleaners whose owners have chucked them out in disgust.


February 13, 2017, 7:11 pm

I have owned two Dyson vacuums and they have disappointed. They are attractive, but they cannot hold a candle to other leader cord vacuums. I got them on sale but still paid more than I should. This hair dryer is HILARIOUS. NEARLY $600 FOR A HAIR DRYER? Absurd. Anyone who will pay that much for a hair dryer needs to have their head examined. The ability to pay for something expensive does not mean you should buy it.

Yeah, because everyone has four hands to hold two brushes and two hairdryers? I got this as a Christmas gift from my husband - I wouldn't have asked for it or bought it myself. But, it will lessen the need for trims (£45 a pop) because my hair is smoother, healthier, already. My other hairdryers have burned, dried out, my hair, meaning more cuts and products to tame it. This 'overpriced' item will pay for itself in approx 18- 24 months with savings on hair cuts and taming/styling products.

Sounds like you bought one.

As my wife is a hairdresser of over 40 yrs i decided to buy her a dyson as a gift..Having used it for a few weeks at home and work she tells me it is a superb dryer.Greater speed of drying and greater control of the hair making for a better finish to hair..The salon has now invested in several dysons,so i'm guessing they are worth the money.

So just to be clear you haven't bought this hairdryer? So this isn't a review, just a snotty opinion about price. How useful.Thanks

I find all these negative remarks rather strange as I've had Dyson vacuums for the last 15 years, and yes sure they are fairly expensive but one thing is for sure they have proved to be reliable, very effective and none of them have ever broken!
