Overview of the Logitech MK955 and Wave Keys MK670

The Logitech MK955 Signature Slim Wireless Keyboard and Mouse Combo is priced at $109.99, whereas the Logitech Wave Keys MK670 Combo comes in at $79.99, making the Wave Keys about 27% cheaper. Both products promise a wireless experience, catering to different user needs, with the MK955 targeting larger hands and quiet typing, and the MK670 focusing on ergonomic comfort and natural typing.

Design and Build Quality

In terms of design, the MK955 boasts a sleek and solidly built full-size keyboard with a familiar laptop-style typing experience. This combo is made from recycled plastic, demonstrating Logitech's commitment to sustainability. Meanwhile, the Wave Keys MK670 presents a wavy keyframe design that promotes a natural wrist position, enhancing comfort during prolonged use. The cushioned palm rest with memory foam in the MK670 offers added support, making it suitable for all-day comfort. Both products prioritize aesthetics and usability but cater to different preferences, with the MK955 offering a more traditional layout compared to the ergonomic focus of the MK670.

Typing Experience

The typing experience differs significantly between the two combos. The MK955 is designed for quiet typing, featuring SilentTouch technology that reduces click noise by 90%. This is ideal for office environments or shared spaces. In contrast, the Wave Keys MK670 emphasizes a more natural typing posture with its ergonomic design, which places hands, wrists, and forearms in a comfortable position. While both products feature quiet mice, the MK670’s design is particularly suited for users who prioritize comfort over noise reduction.

Connectivity Options

Both the MK955 and MK670 offer versatile connectivity options. The MK955 allows seamless switching between three devices, making it suitable for users who multitask across personal and work computers. It connects via Bluetooth or the Logi Bolt USB receiver. The Wave Keys MK670 also supports Bluetooth and Logi Bolt connectivity, enabling easy switching between PC, tablet, and phone. However, it's important to note that the Easy-Switch feature does not apply to the MK670's mouse, which could limit its versatility compared to the MK955's multi-device functionality.

Battery Life

Battery life is a key consideration for wireless devices, and both combos excel in this area. The MK955 offers an impressive battery life of up to 36 months for the keyboard and 24 months for the mouse, ensuring minimal interruptions due to battery changes. In comparison, the Wave Keys MK670 boasts similar longevity, with up to 3 years for the keyboard and 2 years for the mouse. While both combos offer excellent battery performance, the MK955 has a slight edge in terms of keyboard longevity.

Customization and Functionality

Customization features are a standout aspect of both products. The MK955 includes customizable keys and buttons that can be programmed using the Logi Options+ App, enhancing productivity for users who rely on shortcuts. Similarly, the Wave Keys MK670 allows users to personalize their experience with the same app, making it easier to streamline workflows. While both products offer customization options, the MK955's additional device-switching capability may provide greater functional advantages in a multi-device setup.

Environmental Impact

Sustainability is a consideration for many consumers today. The MK955 incorporates a minimum of 48% post-consumer recycled plastic for the keyboard and 25% for the mouse. On the other hand, the Wave Keys MK670 features an impressive 61% recycled plastic for the keyboard and 65% for the mouse. This makes the MK670 a more environmentally friendly option, appealing to users who prioritize sustainable products while still ensuring comfort and functionality.

Which should you buy?

Choosing between the Logitech MK955 Signature Slim Wireless Keyboard and Mouse Combo and the Wave Keys MK670 Combo largely depends on your specific needs. If you require a quiet typing experience with the ability to switch between multiple devices, the MK955, priced at $109.99, may be worth the investment. However, if comfort and ergonomic design are your top priorities, the Wave Keys MK670, at $79.99, offers significant savings without sacrificing quality. Ultimately, both products are excellent choices, but the best option will depend on whether you value multi-device functionality or ergonomic comfort more.
