Ergohaven rolls out the K:04, a split ergonomic mechanical keyboard that blends a compact 58‑key layout with wireless Bluetooth LE. Two halves communicate independently, letting users tap a thumb‑cluster key to pull up secondary layers that house the number row and navigation functions. Columnar stagger keeps keys aligned to fingertip curvature, easing strain for users.

The K:04 starts at $180 for the bare chassis, with switches and low‑profile blank keycaps adding $60 to reach $240. Branded keycaps push the price to $265 or $280 depending on style. Modular options—rotary encoder, touchpad, or 32 mm trackball—cost $35, $55, or $65 respectively, extending the keyboard’s functionality beyond typing for enthusiasts and professionals who value.

Ergohaven’s Entropy software, built on Vial, lets users configure each half’s layout and module functions. Removing a module preserves its settings, so re‑inserting restores the previous configuration instantly. The keyboard supports Gateron LP 3.0 switches by default but can host full‑height MX switches with an extra plate, offering broad choice for tactile preference and comfort.

By combining a minimalist form factor with interchangeable modules, the K:04 targets power users who need more than a standard 60‑percent board. It also appeals to ergonomics advocates seeking a split layout that reduces wrist strain. With modular upgrades and a flexible keycap lineup, the K:04 redefines what a portable mechanical keyboard can achieve today.
