AI Verdict
This is a compact, split ergonomic keyboard with a hard, non-removable palm rest, multi-device Bluetooth and 2.4G connectivity, and USB-C charging.
This keyboard is a situational fit for those prioritizing a compact, split ergonomic design and multi-device connectivity. Its hard, non-removable palm rest and reported hollow key sound are significant compromises, but the ergonomic shape and connectivity options are strong points for specific users.
If the typing sound or wrist rest comfort are critical, look for keyboards with sound-dampening materials or a padded, removable wrist rest.

Pros
- Connects to up to 3 devices via Bluetooth or 2.4G USB receiver, allowing seamless switching.
- Compact split-key design (13.1 inches long, 8.9 inches wide) without a number pad promotes natural shoulder alignment.
- Features 2 adjustable tilt legs to position the keyboard for relaxed wrist posture.
- Built-in rechargeable battery offers 250 hours of standby time after a 2-hour charge via USB-C.
- Includes dedicated Select-all, Copy, Cut, and Paste function keys for productivity.
Cons
- Keys produce a hollow, cheap sound, especially in the middle, due to a likely hollow interior without sound-absorbing materials.
- The wrist rest is hard, unpadded, and non-removable, which may not suit all users for extended typing.
- One early user reported the EK04 only having 2.4GHz dongle connectivity with no Bluetooth, contradicting product claims.
- Requires a significant adaptation period to get used to the split layout, potentially impacting typing speed initially.
- Function key layout for Copy (F8) and Cut (F9) is inconsistent with standard keyboard shortcuts.
Dimension Scores
While it uses scissor-switch keys, multiple early users report a 'hollow' and 'cheap' sound when typing, detracting from the experience.
Offers multi-device switching between 2.4G USB receiver and Bluetooth, but there's a conflicting report of a unit lacking Bluetooth.
Backlighting is not mentioned in any product specifications or user feedback, indicating its absence.
The keyboard 'looks and feels well-built' externally, but the internal 'hollow shell' causing poor typing sound suggests a compromise in material use.
Best For
- Users seeking ergonomic relief from wrist and shoulder strain in a compact form factor.
- Individuals who frequently switch between up to three devices (PC, Mac, tablet).
- Workspaces where a separate numeric keypad is preferred or not needed.
- Those who prioritize a clutter-free desk with a smaller keyboard footprint.
Not Recommended For
- Typists sensitive to keyboard sound, as the keys are reported to sound hollow.
- Users who require a soft, cushioned, or removable wrist rest.
- Anyone needing a built-in 10-key numeric pad.
- Individuals unwilling to adapt to a split ergonomic layout.
Watch Out For
- The keyboard's internal construction leads to a 'hollow' and 'cheap' sound when typing, which can be distracting during prolonged use.
- Despite product specifications, at least one early user reported the EK04 lacking Bluetooth connectivity, relying solely on a 2.4GHz dongle.
- The integrated wrist rest is hard and not cushioned, which might cause discomfort for users accustomed to softer support.
- You'll need to commit to a learning curve; adapting to the split ergonomic layout can take weeks to regain typing speed.

What Buyers Say
Even though the official Amazon listing shows a future availability date, early impressions from Reddit users and other sources indicate the ProtoArc EK04 is already out there. The most consistent feedback points to a significant issue with the keyboard's sound; many find the keys sound hollow and cheap, which can be a real deal-breaker for daily use. Users generally appreciate the compact, split ergonomic design and the ability to switch between multiple devices. However, the hard, non-removable wrist rest is a recurring point of contention, and there's conflicting information about whether Bluetooth is actually present.
“Man, this thing looks cool, but the clacky sound from the keys is driving me nuts. My old keyboard sounded better, seriously. And that wrist rest? Hard as a rock, not what I expected.”
Common Praise
- Compact size and split design help with wrist and shoulder comfort.
- Ability to switch between 3 devices using either 2.4G or Bluetooth is convenient.
- Dedicated function keys for Select-all, Copy, Cut, and Paste are useful for productivity.
- Scissor-switch keys are lightweight and have satisfying travel.
Common Complaints
- Keys sound hollow and cheap, like typing on an empty box.
- The wrist rest is hard, unpadded, and cannot be removed.
- Confusion and conflicting reports regarding the presence of Bluetooth connectivity.
- Learning curve for the split layout can be frustrating and slow down typing initially.
Ownership Tips
- The hollow sound of the keys becomes more noticeable and irritating over time, especially in quiet environments.
- The hard, non-removable wrist rest can lead to discomfort during long typing sessions, requiring external padding for some users.
- The split layout takes a dedicated effort to master; expect a temporary drop in typing speed for several weeks.
- Confirming Bluetooth functionality upon purchase is crucial, as some units might only offer 2.4G wireless.
Frequently Asked Questions
Does this keyboard actually have Bluetooth connectivity?
The product specifications state it connects via both Bluetooth and a 2.4G USB receiver. However, one early user reported their EK04 unit only had 2.4GHz connectivity.
Is the numeric keypad integrated into the main keyboard?
No, the EK04 is a compact keyboard without a built-in numeric pad. It is designed to be used with a separate, optional numeric keypad.
Is the wrist rest soft or cushioned?
No, the wrist rest is explicitly described as a 'hard palm rest' with a leather surface and is not cushioned. It is also non-removable.
How long does the battery last on a single charge?
The keyboard features a built-in rechargeable battery that provides 250 hours of standby time after a 2-hour full charge.
How difficult is it to get used to the split layout?
It takes time to adapt to a split ergonomic layout compared to a traditional keyboard, with users reporting it can take a couple of months to regain typing speed.
Buying Guide
When you're looking at ergonomic keyboards, you're trying to find something that helps your body feel better while you type. The big things are usually how it splits your hands, how much your wrists are angled, and if it has a comfy place for your palms. Don't just grab the cheapest one; think about how long you'll be using it every day and what kind of support your body actually needs.
Split Design
This means the keyboard is literally split into two halves, often angled. It helps keep your wrists and shoulders in a more natural, relaxed position, like how your arms would naturally rest if you weren't typing. It can reduce strain but takes some getting used to.
Palm Rest (Hard vs. Soft, Removable vs. Integrated)
This is where your palms or wrists rest. A hard, integrated one, like on this keyboard, provides consistent support but might not be comfortable for everyone. A soft or removable one offers more cushioning and flexibility to adjust your setup.
Connectivity (Bluetooth vs. 2.4G USB Receiver)
Bluetooth lets you connect wirelessly to multiple devices without a dongle, freeing up USB ports. A 2.4G USB receiver usually offers a more stable, direct connection but uses up a USB port and is typically for one device. Multi-device keyboards let you switch between them easily.
Alternatives
If the hollow typing sound or hard wrist rest are deal-breakers, look for ergonomic keyboards with padded, removable wrist rests and user reviews specifically mentioning quiet keypresses or sound-dampening construction.
