Dimension comparison
Design and build quality
Both peripherals in this comparison come from Logitech, a brand known for sturdy construction and professional aesthetics. The Logitech MX Keys S Combo presents a full-size keyboard layout designed to sit securely on a desk. It features carefully-crafted keys intended for quiet operation. The Logitech MK850 Performance Wireless, according to its provided specifications, engineers both the mouse and keyboard for hours of work, with a stable keyboard base and a mouse sculpted for the hand. While both aim for durability, the higher price point of the Logitech MK850 Performance Wireless suggests potentially premium materials, though the Logitech MX Keys S Combo maintains a solid build suitable for daily office tasks.
Typing Experience
Typing comfort is critical for productivity. The Logitech MX Keys S Combo offers a full-size keyboard with carefully-crafted keys designed for quiet and comfortable typing over long periods. The Logitech MK850 Performance Wireless takes this further with a laptop-like profile and spherically-dished keys shaped specifically for fingertips. This design delivers a fast, fluid, and precise typing experience. Additionally, the Logitech MK850 Performance Wireless features smarter illumination where backlit keyboard keys light up as hands approach, adapting to the environment. This gives it an edge in low-light conditions compared to the standard layout of the Logitech MX Keys S Combo.
Mouse Performance
Navigation speed and precision differ between the two models. The Logitech MX Keys S Combo includes a contoured right-handed mouse with a hyper-fast scroll wheel, enabling users to fly through documents and web pages efficiently. The Logitech MK850 Performance Wireless steps up performance with MagSpeed, described as Logitech's fastest and most precise scroll wheel capable of scrolling 1000 lines per second. It also boasts an 8K DPI sensor that tracks anywhere, even on glass. For users requiring high-precision tracking on diverse surfaces, the Logitech MK850 Performance Wireless holds a clear advantage.
Connectivity and Compatibility
Modern workflows often require switching between multiple devices. The Logitech MX Keys S Combo is fully multi-device and multi-OS friendly, allowing users to start typing on a computer and switch to a tablet, phone, or second computer. It supports dual connectivity, letting users choose between USB or Bluetooth. The mouse can pair with up to 3 screens. The Logitech MK850 Performance Wireless is also wireless but the provided data emphasizes performance features over specific connectivity counts. The explicit support for pairing with multiple screens makes the Logitech MX Keys S Combo a strong contender for multi-device users.
Software and Customization
Software integration enhances hardware utility. The Logitech MX Keys S Combo utilizes Logitech DuoLink software to link the mouse and keyboard together for custom functionality and smarter navigation, requiring the download of Logitech Options. The Logitech MK850 Performance Wireless uses the Logi Options+ app to enable Smart Actions shortcuts. These shortcuts allow users to automate repetitive tasks by performing multiple actions with a single keystroke. The Logi Options+ app also offers more lighting customizations for the Logitech MK850 Performance Wireless, providing deeper control over the device's behavior and appearance.
Comfort and Ergonomics
Ergonomics play a vital role in preventing strain during long work sessions. The Logitech MX Keys S Combo includes a cushioned palm rest, providing immediate support for the wrists while typing. The mouse is contoured for right-handed use. The Logitech MK850 Performance Wireless is engineered for deeper focus with a stable keyboard at an optimum angle and a mouse sculpted for the hand. While both prioritize comfort, the inclusion of a dedicated cushioned palm rest gives the Logitech MX Keys S Combo a tangible benefit for users seeking immediate wrist support without additional accessories.
Price and Value
Value is determined by the balance of features and cost. The Logitech MX Keys S Combo is priced at $89.99, offering a comprehensive keyboard and mouse solution with multi-device support and comfort features. The Logitech MK850 Performance Wireless is priced at $199.99, more than double the cost. While the Logitech MK850 Performance Wireless offers advanced specs like backlighting and an 8K DPI sensor, the price premium is significant. For most users, the Logitech MX Keys S Combo provides the essential wireless performance and comfort needed for daily tasks at a much more accessible price point.
Which one should you buy?
Choosing between these two depends on your specific needs and budget. If you require advanced features such as backlit keys for low-light environments, an 8K DPI sensor for precision tracking on glass, and automation tools via Smart Actions, the Logitech MK850 Performance Wireless justifies its higher cost. However, for the majority of users seeking a reliable, comfortable, and multi-device friendly setup, the Logitech MX Keys S Combo is the superior choice. It delivers core performance features like hyper-fast scrolling and dual connectivity at less than half the price, making it the better value proposition for general productivity.
