Product Description

The Firstblood B81 Crystal is a compact 75% mechanical keyboard designed for users who want a visually distinctive, transparent design combined with versatile switch customization. It suits hobbyists and gamers who value a unique aesthetic and the ability to swap switches without soldering. Its wireless and wired connectivity options make it flexible for different setups.

Key Features

  • Full-key hot-swappable Kailh sockets allow easy switch replacement or experimentation without tools.
  • Includes letter stickers with transparent backgrounds, letting users choose whether to display legends on keycaps.
  • Crystal damping knob offers tactile feedback and ergonomic control, beneficial for gaming and precise input.
  • Bluetooth 5.0, 2.4G wireless, and wired connectivity provide multiple connection modes for convenience.

Build Quality

  • Constructed with a precision-drilled acrylic surface for high translucency and durability.
  • Gasket mounting structure reduces typing noise and vibration, improving acoustic comfort.
  • Ultra-high PC keycaps with FCSA profile support a consistent typing feel and durability.

Typing Experience

  • Linear Kailh Ice Star Jelly switches require moderate force, suitable for smooth keypresses without tactile bumps.
  • Gasket mount softens keystrokes, reducing harsh feedback and noise.
  • Customizable switch options allow users to tailor typing feel to personal preference.

Compatibility

  • 75% layout with 81 keys fits compact desk setups while retaining essential keys.
  • Compatible with Windows and Mac systems.
  • North-facing LEDs improve compatibility with keycap designs that have side legends or translucent elements.

Trade-offs

  • Transparent acrylic case may show dust and fingerprints more easily than opaque designs.
  • Linear switches may be less suitable for users who prefer tactile or clicky feedback.
  • Unknown battery life and latency details for wireless modes.
