Dyson Supersonic – An Honest Review Of The $400 Hair Dryer

Dyson Supersonic Hair Dryer Review – Most women just want an easy-to-use hair dryer that dries our hair fast and efficiently while reducing frizz. At one time this was a lot to ask for, but just like all other technology, hair dryers have evolved. Now here we are with the Dyson Supersonic, a feature-rich piece of technology that is changing how we look at hair dryers. This is a more-than-decent dryer so it gets 4.2 out of 5 stars. Keep reading to find out why.

Features of the Dyson Supersonic Hair Dryer

In this section, I am going to talk about some key features of the hairdryer. I will also give it a rating on a scale of 0 to 5, with 0 being “terrible”, and 5 being “the best thing that ever hit the market”. You can check out the snapshot table below for a quick view of the ratings. They are explained in detail below the table.

Ease of Use – 3/5

Dyson is pushing the boundaries of innovation in the hair dryer industry. With that being said, the Supersonic hair dryer has so many features that it could get a little complicated. Trying to understand the technology, figure out the best settings, fiddle with the magnetic attachments–by the time you do all that you may just want to get a simple hair dryer with two settings so you can dry your hair and move on with your day.

Durability – 5/5

Just as Dyson is known for innovation, they are also known for the high quality of their products but we do have one concern. This hair dryer is essentially a computer and computers are sensitive. They don’t stand up well to bumps and bruises. What happens if you drop the dryer? The Supersonic does come with a two year warranty, but it is limited to parts and labor due to defect only so this is something to keep in mind.

Heat Output – 5/5

The Supersonic has four different heat settings and three different airflow settings. Most inexpensive hair dryers just have High and Lo settings and you are lucky if you get a Medium setting. Being able to customize the amount of heat that comes out of the dryer as well as how fast it comes out is convenient.

The Supersonic features a glass bead thermistor (which is essentially a sensor and a current limiter)connected to a microprocessor. This helps to control the temperature so the dryer doesn’t get too hot. The microprocessor measures the temperature twenty times per second, so it is constantly regulating temperature.

Price – 2/5

Dyson has been around for decades and everyone knows that their products are expensive. The Supersonic is no exception. While it is common for people to pay more money for the best in class, the Supersonic’s price may be a little bit inflated even for the number of amazing features it has. It is around three to five times more expensive than the average hair dryer. That means that this hair dryer isn’t for everyone–it is geared more towards well-off and wealthy people who are really paying for the name more than the features.

In our opinion, the price tag is enough to make most people turn away from the product and Dyson knows this, so it would seem that they are marketing to only a select group of shoppers.

Options – 5/5

Everyone likes options and the Dyson Supersonic hair dryer has no shortage of them. The hair dryer comes in six different color combinations with one of them being limited edition. The dryer also has a lot of accessories to choose from including three different attachments that come with the dryer. Another option to choose from is the standard model or the professional model.

Power – 5/5

There is no doubt that the Dyson Supersonic hair dryer is powerful. It has a digital V9 motor that is quieter than other hair dryers. This is great for people who have babies, jumpy pets, or anyone else in their household that gets disturbed by loud noises.

The motor is also very powerful. It features a 13-blade impeller that produces 13 liters of air every second. The Supersonic has air multiplier technology in the head of the dryer, so once all that air leaves the motor, it is multiplied by three when it comes out to your hair. The Supersonic does all of this on only 41aW of power.

Review of Other Features

Dyson’s goal with the Supersonic was to create a high-end hair dryer that is powerful, dries faster, and is easier to use. The Supersonic meets two out of three of those goals. You know the old saying: “two out of three ain’t bad”. However, for the price tag, it would be nice to have all three.

The hair dryer is definitely powerful. Having a powerful motor is a hallmark of Dyson’s products. This is good for people with thick hair but people with thin hair really don’t need this much of power. Even the low setting could be too harsh for thin hair.

One thing that does get a solid 5 is the faster drying time. For people with thick hair, this is one of the most valuable features of the dryer. If features a high-velocity jet-stream of air that dries six times faster than the average hair dryer.

The design of the dryer is another area to look at. Dyson made an attempt at a modern design that solves common hair dryer problems but they may have fallen a bit short. Putting the motor in the handle was supposed to make the hair dryer easier to hold and balance. While it does do this, it also makes it slightly heavier so its like you give away one feature to gain one. The buttons are on the back, very close to where you hold the dryer so you could accidentally turn the dryer on/off or change settings when you don’t intend to.

Comparison to Similar Dryers on the Market

The Dyson Supersonic is one of a kind, but there are some dryers that could be compared to it. To make it fair, we choose popular brand name dryers with similar features and accessories.

Dyson Supersonic vs. Conair 225PR

This Conair 225PR comes with 2 attachments instead of three and the power cord is about four feet shorter than the Supersonic, but overall they perform basically the same functions. While the Conair isn’t computerized, it does have high-torque technology for fast drying as well as technology for heat protection and anti-frizzing. The best part is that it only cost one-tenth of the price of the Dyson Supersonic hair dryer.

Dyson Supersonic vs. Paul Mitchell Pro Tools Express Ion Dry

Paul Mitchell Pro Tools Express Ion Dry

The Express Ion Dry+ lets you blow-dry, blowout, and style your hair like a pro. The advanced technology of the Express Ion Complex™ provides shiny, healthy results while a powerful motor quickly and gently dries hair.

At only a third of the cost of the Supersonic, this Paul Mitchell hair dryer has more speed and heat settings than the Supersonic. It features an LCD display so you can easily see the temperature and settings. It also has a cool shot feature. When comparing these two hair dryers, Dyson is the clear winner when it comes to features and advanced technology, but if you are looking to save money on a high-tech dryer, then Paul Mitchell’s is a great choice.

Dyson Supersonic vs. Revlon Salon Infrared Hair Dryer

Revlon Salon Infrared Hair Dryer
Revlon Hair Tools is dedicated to helping women achieve beautiful hair they’ll love!

The Revlon hair dryer isn’t as advanced as the Dyson, but it does have some great features. This one also has a cold shot button and two speed and heat settings. It has an ion select dial that lets you choose how much ions you want. It also has a turbo boost button to increase airflow. All of this is computerized on the Dyson so it would be more of a hassle using these features on the Revlon.


The Dyson Supersonic hair dryer is one of the best and most innovative hair dryers to ever hit the market. We definitely recommend this hair dryer if you can afford it.

It works great, we aren’t disputing the quality, but it is very expensive for an at-home hair dryer. If this price was for the professional version then maybe it would be an easier pill to swallow, but as it turns out the professional version cost even more!

If the Dyson is out of your budget, our recommendation would be to check out our reviews of the Nume Signature or the Conair InfinitiPRO.
