Price Comparison

The Logitech MK345 Wireless Keyboard and Mouse Combo is priced at $32.75, while the Logitech Wave Keys MK670 Combo is significantly higher at $79.99. This means the MK345 is about 59% cheaper than the MK670. For budget-conscious consumers, the MK345 offers a compelling value proposition without sacrificing essential features. The price difference may influence buyers, particularly those looking for a reliable wireless keyboard and mouse setup without overspending.

Design and Ergonomics

In terms of design, the Logitech Wave Keys MK670 Combo stands out with its ergonomic features, especially the wavy keyframe that promotes a natural typing position. This design is specifically tailored for comfort during extended use, making it an excellent choice for those who spend long hours typing. In contrast, the MK345 features a traditional full-size keyboard layout with a palm rest but lacks the ergonomic enhancements of the MK670. While both products are designed for comfort, the MK670 is better suited for users prioritizing ergonomic support.

Connectivity Options

When it comes to connectivity, both products offer reliable wireless options, but the MK670 provides more versatility. The Wave Keys MK670 can connect via Bluetooth or the Logi Bolt USB receiver, allowing users to switch effortlessly between devices, including PCs, tablets, and phones. This multi-OS compatibility is a significant advantage for users who operate across different platforms. The MK345, on the other hand, utilizes a straightforward 2.4 GHz USB receiver for a reliable connection but lacks the Bluetooth capability. This difference may sway users who value connectivity flexibility.

Battery Life

Battery life is another critical factor to consider, with both products offering impressive longevity. The MK345 boasts a keyboard battery life of up to three years and a mouse battery life of 18 months, which is quite substantial. In comparison, the MK670 provides a keyboard battery life of up to three years and a mouse life of up to two years. While both products have robust battery performance, the MK345 edges out slightly in mouse longevity. Users who prioritize battery efficiency might lean toward the MK345, given its extended mouse battery life.

Typing Experience

The typing experience on the Wave Keys MK670 is designed for comfort and efficiency, with its compact keys facilitating a more natural shoulder position. This ergonomic design reduces strain during long typing sessions, which can be a significant advantage for users who type extensively. Conversely, the MK345 offers a quiet typing experience with a familiar full-size layout but does not provide the same level of ergonomic support. While both keyboards deliver comfortable typing experiences, the MK670 is specifically crafted for those who value ergonomic benefits.

Mouse Features

The mouse included in the MK670 Combo features SilentTouch technology, which reduces click noise by up to 90%, making it ideal for quiet environments. Additionally, the Signature M550 L mouse is designed with a rubber grip for comfort and precision. In contrast, the mouse that comes with the MK345 is comfortable and suitable for all-day use but lacks the advanced noise reduction features found in the MK670. Users who work in shared spaces or need a quieter mouse may prefer the MK670 for this reason.

Build Quality and Materials

In terms of build quality, the Wave Keys MK670 is made from plastic that includes certified post-consumer recycled materials, with 61% for the keyboard and 65% for the mouse. This environmentally-conscious design may appeal to consumers who prioritize sustainability. On the other hand, the MK345, while reliable and durable, does not highlight any eco-friendly materials in its construction. The difference in materials may influence buyers who are environmentally conscious and prefer products made from recycled content.

Which should you buy?

Choosing between the Logitech MK345 Wireless Keyboard and Mouse Combo and the Wave Keys MK670 Combo ultimately depends on your specific needs and preferences. If you're looking for a budget-friendly option with solid performance, the MK345 at $32.75 is an excellent choice. However, if ergonomic comfort, advanced connectivity options, and reduced noise are your priorities, the MK670, albeit at a higher price of $79.99, may justify the investment. Each product has its strengths, making it essential to consider what features matter most to you.
