SRI Labs DryQ Vs Dyson Supersonic Nural: We Tested Both
Twenty minutes into a blowout, with your arm aching and the hair dryer drowning out everything else in the room, it’s easy to wonder whether a better hair dryer would make your beauty routine easier. The SRI DryQ and the Dyson Supersonic Nural are both marketed as delivering salon-quality results at home, but there’s about $200 between them. So which one actually delivers? We tested both side by side on the same wig head, measuring weight, noise, airspeed, and how much hair each could dry in three minutes. Want to compare more options? See all seven dryers we tested in our roundup of the best premium hair dryers.
⭐ Quick Verdict
⭐ Best For: The DryQ suits anyone who wants a lighter, foldable hair dryer at a lower price. The Nural suits anyone who wants a quieter hair dryer.
🚫 Not Ideal For: The DryQ isn’t ideal if noise bothers you. The Nural isn’t ideal if you’re paying extra for faster drying, since it tied the DryQ.
✅ Bottom Line: Same drying speed, about a $200 price difference. Choose based on whether weight or noise matters more to you.

How We Tested
We put the SRI DryQ and the Dyson Supersonic Nural through the same three hands-on tests: same equipment, same settings, same wig head. That way, any difference in the results comes from the hair dryers, not from how we tested them.
Hair Dryer Weight
A dryer’s weight matters more than most people expect. If you have long or thick hair, you can spend several minutes holding it over your head, and a heavy hair dryer tires your arm quickly. So we put both the DryQ and the Supersonic Nural on the same digital scale to see how much each one actually weighs.
Hair Dryer Noise
We also measured noise. Using a sound meter, we took a reading at the top airflow setting. That’s the setting most people use to dry the bulk of their hair, and it’s usually the loudest.
Hair Dryer Airspeed Test
Airflow speed is a big part of how fast a hair dryer gets the job done. We set each dryer to its highest airflow setting and measured the air speed with the same airflow meter, held at the same distance from the nozzle.
Three-Minute Hair Drying Test
What matters most with any hair dryer is how much drying it gets done in a set amount of time, so we put both hair dryers against the clock. For each test, we drenched the hair on the same wig head and blotted it with a towel until it stopped dripping. Then we ran the hair dryer for exactly three minutes. When time was up, we graded the hair on a 1-to-5 scale: 1 means still damp, and 5 means completely dry. We ran every test on a single wig head, so results may vary across hair types, especially fine hair or very thick, curly hair.
Performance Test and Results
Weight
Setup: We weighed the SRI DryQ and the Dyson Supersonic Nural on the same digital scale, both without attachments.
Observation: The DryQ came in at 386 grams (about 13.6 oz). The Supersonic Nural weighed 464 grams (about 16.4 oz, or just over a pound). That makes the DryQ about 78 grams (2.8 oz) lighter.
Bottom Line: Both are light enough to hold through a full blowout. The DryQ’s lighter weight is most noticeable if long or thick hair keeps the hair dryer over your head for several minutes.
Noise
Setup: We measured each hair dryer with a sound meter, on its highest airflow setting.
Observation: The Supersonic Nural read about 78 dB, roughly as loud as a vacuum cleaner running nearby. The DryQ read about 85 dB, closer to heavy city traffic. Normal conversation sits around 60 dB.
Bottom Line: The Nural is the quieter of the two. A 7 dB gap is easy to hear, so if noise matters to you, the Nural has the edge. You’ll have to raise your voice to talk over either one at full power. Both stay within NIOSH’s guideline of up to 8 hours a day at 85 dB, so a typical 10- to 15-minute blow-dry isn’t a hearing concern.
Hair Dryer Airspeed Test
Setup: We set both hair dryers to their highest airflow setting and measured air speed with the same anemometer, held at the nozzle.
Observation: The DryQ’s air moved at 1,434 feet per minute (about 16.3 mph). The Supersonic Nural’s moved at 1,390 feet per minute (about 15.8 mph).
Bottom Line: That’s a difference of about 3%, too small to notice while drying. On airspeed, the two are effectively tied. Real drying speed comes down to more than one number, which is what our three-minute test checks next.
Three-Minute Hair Drying Test
Setup: We soaked the hair on the same wig head, towel-dried it until it stopped dripping, then ran each dryer for exactly three minutes on its highest settings. We rated the results on a 1-to-5 scale, where 1 is still damp and 5 is completely dry.
Observation: The Supersonic Nural left most of the hair dry and the ends completely dry, with a little dampness left near the roots. The DryQ also dried the hair well in three minutes, leaving it close to fully dry.
Bottom Line: Both dryers scored 4.5 out of 5. In three minutes, each got the hair close to fully dry, so neither has a clear edge on drying speed in our test.
Rating: DryQ 4.5/5 | Supersonic Nural 4.5/5
Overall Results
| Test | SRI DryQ | Dyson Supersonic Nural | Edge | What It Means |
|---|---|---|---|---|
| Weight (no attachments) | 386 g (13.6 oz) | 464 g (16.4 oz) | DryQ (78 g lighter) | The DryQ is about 2.8 oz lighter. That’s most noticeable during long blowouts, when the dryer stays over your head for several minutes. |
| Noise (highest airflow) | 85 dB | 78 dB | Nural (7 dB quieter) | A 7 dB gap is easy to hear. Both are loud enough that you’ll need to raise your voice to talk over them, but the Nural is noticeably quieter. |
| Air speed (highest airflow) | 1,434 ft/min (16.3 mph) | 1,390 ft/min (15.8 mph) | Tie (about 3% apart) | The difference is too small to feel while drying. Both push air at about the same speed. |
| Three-minute drying score | 4.5/5 | 4.5/5 | Tie | Both got wet hair close to fully dry in three minutes, so neither has a clear edge on drying speed. |
SRI DryQ or Dyson Supersonic Nural: Which Should You Buy?
In our tests, the two hair dryers tied on airspeed and drying time. So the choice comes down to what matters more to you: a lighter hair dryer or a quieter one. Price and features come after that.
Who Should Buy the SRI DryQ
The DryQ is the better pick if weight matters to you. At 386 grams, it was about 2.8 oz lighter than the Nural on our scale, which makes a real difference when long or thick hair keeps the dryer over your head for several minutes. It also folds for travel and has a lower list price ($299.99 vs. $499.99).
Choose the DryQ if you:
Have long or thick hair and want a lightweight dryer for long blowouts
Travel often and want a hair dryer that folds
Want to spend less
SRI also says its infrared and red light technology supports healthier hair. We didn’t test that claim, so treat it as a manufacturer claim, not one of our results.
Who Should Buy the Dyson Supersonic Nural
The Nural is the better pick if noise bothers you. It measured 78 dB to the DryQ’s 85 dB, a 7 dB gap you can easily hear, especially in a shared home or early in the morning. It also comes with five magnetic attachments and a 2-year warranty.
Choose the Nural if you:
Want the quieter hair dryer of the two
Want versatile styling options from five magnetic attachments
Want a wider range of styling attachments
Don’t mind paying more
Dyson says its Nural sensors lower the heat automatically as the hair dryer gets closer to your scalp. We didn’t test that feature either.
SRI DryQ vs. Dyson Supersonic Nural: Our Final Verdict
After testing both hair dryers side by side, we found the SRI DryQ and the Dyson Supersonic Nural closer than their price gap suggests. They tied on airspeed and in our three-minute drying test, so neither one dries hair meaningfully faster than the other. The real differences are weight, noise, and price.
The DryQ is the better pick for most people who want a lighter, more affordable hair dryer. It was about 2.8 oz lighter on our scale, it folds for travel, and its list price is $200 lower. If you have long or thick hair and spend several minutes holding a hair dryer over your head, the weight difference is the one you’ll feel.
The Nural is worth the extra cost if noise is a dealbreaker. It was 7 dB quieter in our test, an easy difference to hear. It also comes with more attachments and Dyson’s sensor-based heat features. Just know that the higher price buys you a quieter hair dryer, not a faster one.
Frequently Asked Questions
Which dries hair faster, the SRI DryQ or the Dyson Supersonic Nural?
Neither, in our testing. Both scored 4.5 out of 5 in our three-minute drying test, and their airspeeds were within about 3% of each other. On drying speed, they’re effectively tied.
Is the DryQ quieter than the Dyson Supersonic Nural?
No. In our noise test, the Nural measured about 78 dB and the DryQ about 85 dB on their highest airflow settings. A 7 dB gap is easy to hear, so if noise is a priority, the Nural is the better choice.
Which hair dryer is lighter?
The DryQ. It weighed 386 grams on our scale, compared with 464 grams for the Nural, a difference of about 2.8 oz. That’s most noticeable during long blowouts on long or thick hair.
Is the Dyson Supersonic Nural worth the extra cost?
It depends on what you’re paying for. In our tests, the Nural didn’t dry hair faster than the DryQ. What the higher price gets you is a quieter dryer, five magnetic attachments, and Dyson’s sensor-based Scalp Protect feature, which we didn’t test. If drying speed is your main concern, our results don’t show a reason to pay more.
Does the DryQ’s red light technology actually work?
We didn’t test it. SRI says its infrared and red light technology supports healthier hair, but our tests measured weight, noise, airspeed, and drying time, not hair health. Treat it as a manufacturer claim.
Which hair dryer is better for travel?
The DryQ. It folds, and according to SRI, units ordered after November 27, 2025, are dual voltage. The Nural doesn’t fold.
Do both hair dryers protect hair from heat damage?
Both brands say their dryers use intelligent heat control to regulate temperature and limit heat damage, and both offer multiple heat settings. Dyson adds a Scalp Protect mode that lowers the heat as the dryer gets closer to your head. We didn’t test heat output or hair damage, so these are manufacturer claims.
