Design and Ergonomics

The Logitech Wave Keys MK670 Combo features an ergonomic design that prioritizes comfort during extended typing sessions. This keyboard has a wavy keyframe that promotes a natural typing position, reducing wrist strain. In contrast, the ProtoArc Backlit Bluetooth Keyboard for Mac adopts a flat design that encourages a neutral wrist position, which can also help prevent discomfort. The Wave Keys includes a cushioned palm rest made of memory foam, offering additional support, while the ProtoArc's flat layout minimizes the risk of carpal tunnel syndrome. Both keyboards aim to enhance user comfort, but the Wave Keys leans more towards ergonomic support.

Connectivity

Connectivity options differ significantly between the two products. The Logitech Wave Keys MK670 Combo connects via Bluetooth or the included Logi Bolt receiver, accommodating various devices like PCs, tablets, and phones. This flexibility is enhanced by the Easy-Switch feature, allowing seamless toggling between devices. On the other hand, the ProtoArc Backlit Bluetooth Keyboard specializes in connecting to multiple devices via Bluetooth, supporting up to three devices simultaneously. However, it lacks a USB dongle for wired connections. While both keyboards offer robust wireless connectivity, the Wave Keys provides broader compatibility across multiple operating systems.

Key Features

In terms of features, the Logitech Wave Keys MK670 stands out with its SilentTouch technology, which reduces click noise by 90%, creating a quieter work environment. The ergonomic keyboard also includes customizable shortcuts through the Logi Options+ App, enhancing productivity. Conversely, the ProtoArc offers backlit keys with three brightness levels, making it ideal for low-light conditions. This keyboard also utilizes scissor switches for a responsive typing experience. While the Wave Keys emphasizes comfort and noise reduction, the ProtoArc focuses on versatility and usability in different lighting scenarios.

Battery Life

Battery life is a crucial factor for wireless keyboards, and here the Logitech Wave Keys MK670 has a notable advantage. The keyboard boasts an impressive battery life of up to three years, while the accompanying mouse lasts up to two years on a single set of batteries. In contrast, the ProtoArc keyboard and mouse feature built-in rechargeable batteries, which can be convenient but require periodic charging. The ProtoArc's keyboard has a 1200mAh battery, and the mouse has a 300mAh capacity. Users who prioritize longevity without the need for frequent charging may prefer the Wave Keys for its extensive battery life.

Aesthetic Appeal

Aesthetics play a significant role in a keyboard's appeal, and both products offer distinct styles. The Logitech Wave Keys MK670 features a sleek graphite finish that complements modern setups, while the ProtoArc keyboard and mouse set comes in a stylish Space Gray reminiscent of Apple's products. The backlit keys on the ProtoArc add an extra layer of visual appeal, especially in dimly lit environments. Ultimately, personal preference will dictate which design resonates more with users, but both options cater to contemporary tastes.

Price Comparison

When it comes to pricing, the Logitech Wave Keys MK670 Combo is priced at $79.99, whereas the ProtoArc Backlit Bluetooth Keyboard and Mouse for Mac is more budget-friendly at $59.99. This makes the ProtoArc about 25% cheaper than the Logitech option. While the lower price may attract budget-conscious consumers, it’s essential to weigh the additional features and ergonomic benefits that the Wave Keys offers against the savings of the ProtoArc. Users should consider their specific needs when evaluating price versus features.

Compatibility

Compatibility is another critical factor to consider. The Logitech Wave Keys MK670 is designed to work with multiple operating systems, including Windows, macOS, iPadOS, and ChromeOS, making it an excellent choice for users with varied devices. The ProtoArc keyboard, however, is specifically tailored for Mac users, supporting Mac OS 10.12 and later, and is not compatible with devices prior to 2013, nor with Windows or Linux systems. Users who operate across different platforms may find the versatility of the Wave Keys much more appealing.

Which should you buy?

Choosing between the Logitech Wave Keys MK670 Combo and the ProtoArc Backlit Bluetooth Keyboard and Mouse for Mac depends largely on your specific needs and preferences. If you prioritize ergonomic comfort, extensive battery life, and compatibility across various operating systems, the Wave Keys is the superior choice despite its higher price. However, if you are looking for a more budget-friendly option with a stylish design and solid functionality for Mac devices, the ProtoArc could be the better fit. Ultimately, consider your usage patterns and the features that matter most to you before making a decision.
