The Philips S9980/59 is a rotary shaver from the 9000 Series Limited Edition, finished in a distinctive blue. It utilizes SkinIQ technology and a Power Adapt sensor that reads hair density 500 times per second, allowing the device to automatically adjust its power to match your beard's thickness. To ensure a comfortable experience, the Pressure Guard sensor lets you know if you are pressing the shaver too hard or too light against your skin. Three flexible 360-D rotary heads move freely to follow the contours of your face, while the Lift & Cut system works to shave as close as 0.00 mm. The blades are crafted from high-performance space-grade steel and are self-sharpening, which maintains their effectiveness for up to two years. Because the housing is waterproof, you can use the device for both wet and dry shaving. This model is powered by a Li-Ion battery providing 60 minutes of cordless runtime after a one-hour charge. For maintenance, it comes with an automatic cleaning station and cartridge, though a beard trimmer attachment is also included for different styling needs. You can further manage your grooming routine via the Philips Shaving app, and the included travel pouch makes it easy to take the system and its charger base on the go.
