Design and Ergonomics

The Logitech Wave Keys MK670 Combo offers an ergonomic design that promotes comfort during extended use, while the ProtoArc Foldable Keyboard and Mouse prioritize portability for on-the-go productivity. The Wave Keys features a wavy keyframe design and a cushioned palm rest made with memory foam, ensuring that wrists and forearms are positioned naturally for comfortable typing. In contrast, the ProtoArc's ultra-slim profile and folding mechanism allow it to be easily transported, making it ideal for frequent travelers. The Wave Keys is designed for medium- to large-sized hands, while the ProtoArc maintains a flat typing surface that might not provide the same level of ergonomic support.

Portability

When it comes to portability, the ProtoArc Foldable Keyboard and Mouse excel with their compact and lightweight design. This combo includes a carrying hard case and can be folded for easy transport, making it particularly well-suited for those who travel frequently. The Wave Keys, while compact, lacks the foldable feature, making it less convenient for on-the-go use. For users who prioritize the ability to work from anywhere, the ProtoArc's fold-and-go mechanism and robust carrying case make it a more convenient option.

Connectivity Options

Both the Logitech Wave Keys MK670 and ProtoArc Foldable Keyboard and Mouse offer versatile connectivity options, but they cater to different user needs. The Wave Keys can connect via Bluetooth or Logi Bolt, allowing users to switch easily between multiple devices, including PCs, tablets, and phones. On the other hand, the ProtoArc can connect to up to three devices using 2.4G and Bluetooth, making it suitable for users who frequently switch between different devices. While both products support multi-OS compatibility, the ProtoArc's ability to connect seamlessly with three devices could be more advantageous for users with diverse setups.

Battery Life

Battery life significantly favors the Logitech Wave Keys MK670 Combo, boasting up to three years for the keyboard and two years for the mouse with standard use. In comparison, the ProtoArc features rechargeable components, with auto-sleep functionality extending standby to 150 days for the keyboard and 200 days for the mouse. While the ProtoArc allows for convenient recharging and eliminates the need for frequent battery changes, the long-lasting performance of the Wave Keys may be preferable for users who want to avoid the hassle of recharging frequently.

Typing Experience

The typing experience differs notably between the two products. The Logitech Wave Keys MK670 Combo features a wavy keyframe that aligns with the natural position of the hands, promoting a comfortable typing experience for long periods. Additionally, the cushioned palm rest enhances wrist support. Meanwhile, the ProtoArc's flat design and whisper-quiet scissor switches provide a different typing feel, emphasizing silence and portability over ergonomic support. Users who spend considerable time typing may find the Wave Keys more comfortable, while those who type less frequently or prioritize quiet operation may prefer the ProtoArc.

Mouse Functionality

The mouse included in the Logitech Wave Keys MK670 Combo utilizes SilentTouch technology, which reduces click noise by 90%, creating a more peaceful work environment. It is designed with a contoured shape and rubber grip, ideal for medium- to large-sized hands. Conversely, the ProtoArc’s ultra-slim mouse features three adjustable DPI modes for precision, making it adaptable for various tasks. While the Wave Keys mouse focuses on comfort and quiet operation, the ProtoArc mouse emphasizes versatility and portability, appealing to users who require precision in different work scenarios.

Price Comparison

Both the Logitech Wave Keys MK670 Combo and the ProtoArc Foldable Keyboard and Mouse are priced at $79.99, making them equally accessible in terms of cost. However, the ProtoArc's average price over the last 90 days is about $72.87, indicating that it could be perceived as a more cost-effective choice if purchased during sales or promotions. Despite this, the Wave Keys offers significant ergonomic advantages, which may justify its price for users prioritizing comfort over portability.

Which should you buy?

Choosing between the Logitech Wave Keys MK670 Combo and the ProtoArc Foldable Keyboard and Mouse ultimately depends on your specific needs. If comfort and ergonomic design are your primary concerns, the Wave Keys is the superior option, offering a typing experience designed to reduce fatigue during long hours of use. However, if you prioritize portability, the ProtoArc excels with its foldable design and easy transport capabilities, making it ideal for business travelers. Both products are priced the same, but their features cater to different user requirements, so consider your workspace and typing habits before making a decision.
