Equipped with the new Bronion Technology, it significantly slows down ion reduction and maintains 99% negative ion output over the long term, delivering shiny and healthy hair. With the Smart Silencer installed, it reduces noise by 2dB without compromising airflow, wind pressure, or wind speed. The temperature and airflow function enables fast drying. Powered by an AC motor, it delivers maximum airflow and wind pressure. The 77°C warm air helps reduce hair damage. Swiss-made with easily removable filter for simple cleaning. Includes overheat protection, cool shot button, professional-grade temperature and airflow switching, slide switch, and a 3-meter power cord.

I’ve used this hair dryer for several months now and notice a significant improvement in my hair’s shine and smoothness. The ion output is strong and consistent, even after long use. The noise reduction is noticeable, especially in quiet environments. The cool shot function is very useful for finishing styles without overheating the hair.

It performs well and delivers strong ion output. The drying speed is fast, and the cool shot function works well. The only minor issue is the filter needs to be cleaned occasionally, but overall it’s a reliable and effective tool.
Megan Abraham –
I switched from an older Soiris model and noticed a clear difference in hair quality. The shine is much better and the hair feels softer. The overheat protection gives me peace of mind, and the design is professional and easy to use.

Great performance with excellent ion output and quiet operation. The wind pressure is strong, and drying is fast. I do wish the power cord were longer, but otherwise it’s a solid investment for daily use.
