Open Box ProtoArc EK04 Wireless Ergonomic Keyboard

If your workday happens at a kitchen table or in a spare-room office, the ProtoArc EK04 ergonomic keyboard is designed to help you type in a more natural, relaxed posture. It’s a wireless keyboard with a split, wave-shaped layout, a padded wrist rest and a numeric keypad that comes as a separate piece you can put anywhere on the desk. This open-box unit is $59.99.

Why remote workers switch to a split layout

On a standard flat keyboard, both hands sit close together, which can angle your wrists outward and roll your shoulders in over a long day. A split design divides the keys into two angled halves, so your hands can rest closer to shoulder width. The EK04’s layout is designed to reduce muscle fatigue during long typing sessions. It isn’t a medical device, though, so if you already have wrist or shoulder pain, ask a health professional about your setup.

Padded support for your palms

The built-in wrist rest gives your palms somewhere soft to settle between keystrokes, instead of the hard edge of a desk. That matters most on long writing days, when your hands rarely leave the keys.

A numpad that goes where you want it

The separate numeric keypad is what sets the EK04 apart. On most full-size keyboards, the number pad sits on the right and pushes your mouse further away, so your arm reaches out every time you grab it. With the EK04 you can:

• place the numpad on the left and keep the mouse right beside the keyboard;
• put it away on days spent writing rather than working with numbers;
• bring it front and centre for spreadsheets, invoices or tax season.

Setting up the ProtoArc EK04 ergonomic keyboard at home

A few general habits help with any ergonomic keyboard: keep your elbows relaxed at your sides, your forearms roughly level and your monitor around eye level. Give yourself an adjustment period, as split layouts can feel unfamiliar for the first few days, especially for keys near the middle.

The EK04 is rechargeable, with a USB charging cable in the box. Our product sheet doesn’t state the wireless connection type, battery life or supported operating systems. If you need it to work with a specific laptop, tablet or work-issued computer, contact our team before you order.

Round out a work-from-home desk

For video calls, the EMEET OfficeCore M0 Plus speakerphone picks up voices in 360° and reduces background noise and echo. If you’re setting up several desks that share one computer, the NComputing L300 thin client is worth a look. You can browse the rest of our Open Box Computer Accessories for more desk gear.
