Dyson Supersonic: Revolutionary Design Meets Advanced Technology

The Dyson Supersonic represents a complete reimagining of traditional hair dryer design. Unlike conventional dryers with motors in the handle, Dyson moved the digital motor V9 into the head, creating better weight distribution and reduced noise levels.

Key Innovations That Set Dyson Supersonic Apart

Digital Motor V9: The heart of the Dyson Supersonic spins at 110,000 rpm—5 times faster than conventional hair dryer motors. This ultra-fast rotation generates powerful, controlled airflow while remaining surprisingly quiet at 77 decibels (comparable to a washing machine).

Intelligent Heat Control: Advanced microprocessors measure air temperature 40 times per second, automatically adjusting heat output to maintain optimal temperatures. This prevents extreme heat damage that occurs with traditional dryers.

Air Multiplier Technology: Originally developed for Dyson’s bladeless fans, this technology amplifies airflow by 3 times, creating a high-pressure, focused air stream that cuts drying time significantly.

Magnetic Attachments: Five precision-engineered attachments connect magnetically and rotate 360 degrees for easy styling from any angle.
