Dyson Supersonic Hair Dryer vs Oral-B iO Series 9
Side-by-side comparison of features, pricing, ratings, and alternatives.
The Dyson Supersonic Hair Dryer is a high-end hair dryer that uses advanced digital motor technology to dry hair quickly and efficiently. It features intelligent heat control and comes with magnetic attachments for styling and drying.
The Oral-B iO Series 9 pairs a magnetic, micro-vibrating brush head with linear magnetic drive technology for a smoother, gentler brushing motion compared to traditional oscillating-rotating brushes, while still delivering thorough plaque removal. A color-coded smart pressure sensor lights up green, yellow, or red on the handle to indicate ideal, acceptable, or excessive brushing pressure, helping prevent gum damage from brushing too hard. The companion app uses the phone camera during brushing to provide an AI-powered 3D mouth map showing which areas were missed or need more attention, turning brushing into a more guided, data-driven routine.
Around $299.99 MSRP.

4.5 (4)Highly recommend Oral-B iO Series 9
Been a regular user of Oral-B iO Series 9 for a while now. Premium build quality. No major complaints so far. Would recommend.
Decent but has rough edges
Oral-B iO Series 9 is solid overall, though it's not perfect. On the plus side, genuinely useful real-time pressure feedback. That said, app features require a smartphone, which held us back from rating it higher.
Does exactly what we need
We've been using Oral-B iO Series 9 for a few months now and it's genuinely made a difference. Smooth, comfortable brushing motion. No major complaints so far. Would recommend.
