The Braun Oral-B iO 4 is an electric toothbrush designed for adults who want a thorough clean through a combination of rotational and pulsating movements. It utilizes a round Ultimate Clean brush head with medium bristles, operating at 10,500 oscillations and 48,000 pulsations per minute to remove plaque effectively. You can choose from four different brushing modes—Daily Clean, Sensitive, Whitening, and Super Sensitive—allowing you to adjust the intensity based on your gum sensitivity or specific goals. To help you maintain a safe technique, the handle features a smart pressure sensor that glows green when you apply the right amount of force, turning red if you press too hard or white if you are too light. A built-in timer ensures you brush for the recommended two minutes, with zone change alerts to remind you to move across different areas of your mouth. This black model, featuring 1 handle, is powered by a Li-ion battery that provides up to 48 minutes of use, typically lasting around 12 days between charges. For those who prefer guided care, the device synchronizes via Bluetooth with the Oral-B app to provide real-time coaching on your brushing habits. The set comes with a charger and a hard travel case, making it easy to keep the toothbrush protected while you are away from home.
