Sharing is caring!

The Dyson Supersonic, you must have heard of it. He made a lot of noise when he arrived on the market, first of all because of his very high price for a hair dryer but also fortunately for his effectiveness. It also owes it to an innovative technology without strong heat, which damages the hair less, a specialty of Dyson.

opinionAbout the Dyson Supersonic

The Dyson Supersonic is the hair dryer that made the most headlines when it was released. It has both a design never seen before but also unprecedented speed and efficiency. However, it does not use extreme heat which makes it more respectful of your hair fiber. It owes this to Air Multiplier technology Dyson’s


What first characterizes the Dyson Supersonic is its atypical design, never seen before on another device of the same type. When you take it in hand, you can see that it is rather compact compared to a conventional hair dryer. It has a vertical handle, to facilitate handling. Above, we find the ON/OFF button, and below that which allows to engage the cold air jet mode.

As for its blower head, it is hollow, which is what makes the design so atypical. On this head, we have the possibility to adjust the airflow between 3 settings via the left button, and the temperature via the right button. 


The Dyson Supersonic hair dryer is available for sale in 6 different colors . We find the classic fuschia / gray, red / nickel, fuschia / nickel for the most girly colors. For more sober colors Dyson also offers black / nickel, Prussian blue / copper as well as nickel / copper.

Getting started

The Dyson Supersonic is unlike any other hair dryer. Its handling is easier because it is done vertically, as with the Dyson Airwrap. This different grip compared to conventional hair dryers can be disturbing during the first use but you get used to it quickly.

What also sets the Dyson Supersonic apart from other hair dryers is its weight. It weighs 600 g which is slightly higher than a normal hair dryer, which runs around 400, 500 g. Thanks to its ergonomic design, the user feels absolutely no difference in weight.

Its 3m long rotating cord gives you enough room to achieve your hairstyles comfortably. For even more comfort, changing accessories is done in no time since they are all magnetic.


Its more compact design does not mean that the Dyson Supersonic is less powerful than the others. Its blower head conceals a V9 engine that spins its propellers at more than 110,000 revolutions per minute. It propels in one second about 13 liters of air to the amplifier of the device. Its power is 16000 W which is lower than for another device of the same type which bypasses the 24000 W. 

Such power is necessary for the proper functioning of the Air Multiplier technology. It produces high-pressure air, which it diffuses to ensure faster drying despite a lower power than other hair dryers.


The Air Multiplier ionic technology used by the Dyson Supersonic combined with its V9 motor provides a high pressure airflow. This quality air flow allows you to achieve both rapid drying and also to give different textures to your hair (smooth, wavy, brushing). Despite using strong airflow, the temperature is still regulated thanks to intelligent heat control the device’s.


The Dyson Supersonic has a thermal sensor. It measures the temperature up to twenty times per second so that it does not exceed the chosen one. It has 4 temperature settings that you just need to modify using the buttons on the back of the head of the device:

  • 100° C : Ideal for quick drying and easy blow-drying
  • 80° C : Suitable for drying your hair
  • 60° C : Allows gentle drying and even heat distribution
  • 28° C : Cold air option perfect for giving volume or simply gently pre-drying. 

These 4 temperature variations cover a large number of uses and allow the device to adapt to all types of hair. It can be noticed that the highest temperature remains quite low. A classic hair dryer will see its temperatures rise up to 180°C. The Supersonic is however just as efficient as the others thanks to the power of its airflow.

Did you know ? Too much heat can modify the protein of your hair and therefore deteriorate, change the color. In order to fight against this Dyson and its teams have developed the soft drying nozzle which does not make your color fade or dull.


The Dyson Supersonic comes with magnetic accessories that are easy to change. They allow you to achieve different types of hairstyles and vary the textures for your hair. Among the tips we find:

  • 1 smoothing tip, allowing a soft and uniform smoothing in no time.
  • 1 styling tip, which gives shape and volume to your hair.
  • 1 diffuser tip, perfect for curly hair, since it controls frizz while respecting and defining your curls.
  • 1 nozzle diffusing a flow of soft air, it adapts perfectly to fine, weakened and damaged hair. It also makes it possible not to sensitize even more a scalp which is already it.


As for the features of the Dyson Supersonic, first and foremost it dries. This is also what it knows how to do best, and in record time since it is 8 times faster than a conventional dryer. Its various accessories also allow it to diffuse for defined natural curls, smooth and give volume.


Maintenance of the Dyson Supersonic filter is important, as it helps to ensure optimum results. In order to clean it properly, we advise you to remove it (it is at the base of the handle where the cord is) and immerse it in soapy water. The device comes with a specific cleaning brush and a spare filter. So you can use the brush, rinse and dry to finally put your filter back in place. Be careful to make sure it is dry.

In order to guide its users in cleaning the Dyson Supersonic filter, Dyson has produced an explanatory video.

Compared to the Dyson Supersonic, its price is 10 times lower.

Which Dyson Hair Dryer Should You Choose?

Between the Dyson Airwrap and the Dyson Supersonic you’ve probably already wondered which one to choose. If you are looking for a quick hair dryer, we recommend the Dyson Supersonic instead, whose primary purpose is to dry, unlike the Airwrap. 

The Airwrap is a multifunctional device that pre-drys, curls and smooths. It therefore has a functionality that pre-drys, however it is quite coarse since the drying is finalized afterwards by smoothing or curling with the device. The Supersonic is really designed to dry which makes it a better hair dryer even if the Airwrap is a very good device too.

How much does a Dyson Supersonic cost?

The Dyson site sells it at around $399 and its limited edition in red (same options, only the color changes) is displayed at around $429. Other resellers such as Amazon, Boulanger or even Darty sometimes put in place promotions that can save you up to fiftydollars. So be careful if you want to save on the initial price, to monitor the possible reductions before investing in this device.

Where to buy the Dyson Supersonic?

The Dyson Supersonic is available for sale in household appliance stores such as Boulanger or Darty. You can find it in its different colors also on Amazon or Cdiscount. These two platforms have the advantage of seeing many promotions and reductions to offer to the buyer.

It is also possible to obtain a Dyson Supersonic via the brand’s website. It is displayed there at around $399 that it is possible to pay in 4 installments without charge. This is an option that can be very convenient for those who cannot or do not want to pay such a large price in one go.

What are the pros and cons of the Dyson Supersonic?
