Logitech MX Keys S Combo - Performance WirelessLogitech Wave Keys MK670 Combo

Design and Comfort

The Logitech Wave Keys MK670 Combo offers a more ergonomic design compared to the Logitech MX Keys S Combo. The Wave Keys features a wavy keyframe that positions your hands, wrists, and forearms in a natural typing position, enhancing comfort during extended use. Additionally, its cushioned palm rest provides significant wrist support, helping to alleviate pressure during long typing sessions. In contrast, the MX Keys S is designed with a flat, laptop-like profile, which can feel less comfortable for some users over prolonged use. However, both combos cater well to different user preferences, with the MX Keys S leaning towards a sleek, modern design while the Wave Keys emphasizes ergonomic functionality.

Typing Experience

When it comes to typing experience, the MX Keys S Combo excels with its fast, fluid typing capabilities. It features spherically-dished keys that deliver a quieter and more precise typing experience, ideal for those who prioritize speed and accuracy. The Wave Keys MK670 Combo, while comfortable, does not match the MX Keys S in speed but still offers a pleasant typing experience thanks to its compact layout and ergonomic design. Users looking for a more responsive and faster typing experience may prefer the MX Keys S, which is engineered for speed and precision, making it particularly suitable for professional environments.

Mouse Performance

In terms of mouse performance, the MX Keys S Combo’s MX Master 3S Mouse is a standout. It features a high DPI sensor that can track on various surfaces, including glass, and allows for scrolling at an impressive rate of 1,000 lines per second, making it ideal for heavy document navigation. The Wave Keys MK670 Combo comes with the Signature M550 L Wireless Mouse, which while quiet and comfortable, does not offer the same level of precision and speed as the MX Master 3S. For users who require high performance and advanced functionality from their mouse, the MX Keys S Combo is the clear winner.

Connectivity Options

Both the Logitech MX Keys S Combo and the Wave Keys MK670 Combo offer versatile connectivity options. The MX Keys S can connect via Bluetooth or the Logi Bolt USB receiver, allowing for easy pairing with up to three devices across various operating systems, including Windows, macOS, and Linux. The Wave Keys MK670 also supports Bluetooth and Logi Bolt, enhancing its compatibility with multiple devices. While both products offer similar connectivity features, the MX Keys S Combo’s ability to switch between three devices gives it a slight edge for users who work across multiple systems.

Customization Features

Customization is a core feature of both combos, with their respective software enhancing user experience. The MX Keys S Combo allows for extensive customization through the Logi Options+ app, enabling users to create Smart Actions shortcuts for automating repetitive tasks. This feature is particularly appealing for power users who value efficiency. The Wave Keys MK670 Combo also offers customization options through the Logi Options+ app, but it is primarily focused on creating shortcuts for convenience rather than enhancing typing speed and precision. For those seeking advanced customization, the MX Keys S Combo provides more robust options.

Build Quality and Sustainability

In terms of build quality and sustainability, both the Logitech MX Keys S Combo and the Wave Keys MK670 Combo are constructed with post-consumer recycled plastic, reflecting Logitech's commitment to environmental responsibility. The MX Keys S incorporates 26% recycled content, while the Wave Keys includes 61% recycled plastic in its keyboard. Both products are designed to be durable and long-lasting, but the higher percentage of recycled material in the Wave Keys MK670 Combo may appeal to environmentally-conscious consumers more strongly. This commitment to sustainability is a positive aspect for both product lines.

Price Comparison

Price is a significant factor when comparing these two combos. The Logitech MX Keys S Combo is priced at $199.99, while the Logitech Wave Keys MK670 Combo retails for $79.99. This makes the Wave Keys about 60% cheaper than the MX Keys S, making it a more budget-friendly option. While the MX Keys S offers premium features and performance, the Wave Keys MK670 provides excellent value for users looking for a reliable, comfortable typing experience without the additional expense. Price-sensitive consumers may find the Wave Keys MK670 Combo to be the better choice for their needs.

Which should you buy?

Ultimately, the choice between the Logitech MX Keys S Combo and the Wave Keys MK670 Combo depends on your specific needs and budget. If you prioritize high performance, speed, and advanced features, the MX Keys S is the superior option, albeit at a higher price. Conversely, if ergonomic design and affordability are your primary concerns, the Wave Keys MK670 Combo presents a compelling value. Each combo has its strengths, making it essential to consider what features matter most to you before making a decision.
