The Dyson Supersonic is the benchmark fast-drying dryer, the one most others get measured against. TechGearLab scored it 86 out of 100, the top mark in their test group, praising its powerful, well-controlled airflow and handle-mounted motor. It is not always the single fastest in raw minutes; what nothing else matches is the combination of speed, low heat damage, balance, and quiet operation. The price is the only real barrier.
- — Highest-ranked dryer in TechGearLab's lab testing (86/100), with airflow that cut drying time roughly in half versus a standard dryer
- — Digital V9 motor sits in the handle, so the tool is exceptionally well-balanced and light on the wrist during long blowouts
- — Intelligent heat control measures air temperature many times a second to keep the dryer from scorching hair
- — Among the most expensive consumer hair dryers on the market at around $430
- — In one head-to-head test it took 30 minutes to fully dry thick hair versus 20 for the Shark HyperAIR, so it is not always the literal fastest
- — Replacement and accessory costs are high, and the proprietary attachments do not fit other brands
