Dimension comparison
Design and build quality
The Logitech MX Keys S Combo presents a sleek and solidly built full-size bluetooth keyboard design. It is constructed with a focus on sustainability, utilizing recycled plastic for its body. The accompanying mouse is contoured for comfort, aiming to fit well in the hand during extended use sessions. In contrast, the Logitech MK955 Signature Slim Wireless features a stable keyboard with an optimum angle designed for hours of work. The mouse included with this combo is sculpted for the hand, prioritizing ergonomic support. Both devices exhibit a professional aesthetic suitable for office environments, though the Logitech MX Keys S Combo explicitly highlights its eco-friendly material composition.
Typing experience and key feel
Typing performance varies between the two options. The Logitech MX Keys S Combo offers familiar laptop-style typing, designed to provide a comfortable experience across long documents. The keys are shaped to facilitate a natural flow without excessive force. The Logitech MK955 Signature Slim Wireless delivers a fluid typing experience with a laptop-like profile. It features spherically-dished keys shaped specifically for fingertips, aiming to deliver a fast, fluid, and precise typing experience. While both prioritize comfort, the Logitech MK955 Signature Slim Wireless emphasizes precision and speed in its key design.
Mouse performance and precision
Mouse capabilities are a key differentiator in this comparison. The Logitech MX Keys S Combo includes the M750 L Signature Plus wireless mouse, which is designed for larger hands. It allows users to scroll through documents line by line or fly through web pages using the SmartWheel technology. The Logitech MK955 Signature Slim Wireless pairs with the MX Master 3S Wireless Mouse. This mouse features an 8K DPI sensor capable of tracking anywhere, even on glass surfaces. It also boasts MagSpeed, described as Logitech's fastest and most precise scroll wheel, enabling users to scroll 1000 lines per second.
Noise levels and office suitability
For shared workspaces, noise output is critical. The Logitech MX Keys S Combo is engineered for a quiet experience, conjuring focus time with quiet typing and clicking. The included mouse utilizes SilentTouch technology for 90% less click noise, making it highly suitable for open offices. The Logitech MK955 Signature Slim Wireless also offers a quieter typing experience compared to standard mechanical switches. However, the specific 90% noise reduction claim is associated with the Logitech MX Keys S Combo's mouse technology, giving it a slight edge in pure noise suppression metrics provided in the data.
Connectivity and multi-device support
Both combos support multi-device workflows. The Logitech MX Keys S Combo allows users to type and click across personal and work computers, moving seamlessly between a home desktop and work laptop. It supports switching between a laptop, tablet, and phone. The Logitech MK955 Signature Slim Wireless also supports wireless connectivity standards compatible with Windows and macOS. Both devices utilize bluetooth connections to maintain a cable-free workspace, ensuring flexibility when transitioning between different hardware ecosystems during the workday.
Software and customization
Software integration enhances the utility of both peripherals. The Logitech MX Keys S Combo supports the Logi Options+ App, available for Windows and macOS. This allows for customizable keys, buttons, and shortcuts for extended possibilities. The Logitech MK955 Signature Slim Wireless also utilizes the Logi Options+ app. It enables users to automate repetitive tasks by creating and sharing time-saving Smart Actions shortcuts that perform multiple actions with a single keystroke. Additionally, the Logitech MK955 Signature Slim Wireless offers more lighting customizations on the app for its backlit keys.
Price and value proposition
Cost is a significant factor for many buyers. The Logitech MX Keys S Combo is priced at $109.99, positioning it as a more affordable entry into the wireless combo market. It provides solid functionality with a focus on quiet operation and sustainability. The Logitech MK955 Signature Slim Wireless is priced at $199.99, reflecting its premium feature set including backlighting and high-DPI mouse sensors. While the Logitech MX Keys S Combo offers better immediate value due to the lower price, the Logitech MK955 Signature Slim Wireless justifies the higher cost with advanced performance specifications.
Which one should you buy?
Choosing between these two depends on your specific workflow needs. If you work in a quiet environment and prioritize sustainability, the Logitech MX Keys S Combo is the logical choice due to its SilentTouch technology and recycled plastic build at a lower price. If you require high precision, work in varying lighting conditions, or need advanced automation features, the Logitech MK955 Signature Slim Wireless is the superior option. Its 8K DPI sensor and backlit keyboard provide capabilities that the lower-priced model does not match, making it worth the investment for power users.
