Compare Keychron Lemokey L3 vs Lemokey L4 Differences Side by Side

This comparison focuses on the Keychron Lemokey L3 and L4, two 80% aluminum wireless gaming keyboards that share the same 4000 mAh battery, 1000 Hz polling, and QMK/VIA support. The decision is hard because both are premium, full-metal TKL boards from Keychron’s gaming sub-brand, but they differ in plate material, key count, acoustic treatment, and layout options. The L3 includes a knob and macro column, while the L4 emphasizes upgraded acoustic foams and a receiver storage compartment. This guide helps buyers choose based on whether they prefer a softer, more customizable typing feel or a denser, dampened out-of-box sound.

Pros and Trade-offs

Choose the Lemokey L3 if you prefer a softer typing feel from the PC plate, need ISO/JIS layout support, or want a knob and macro column for productivity and modding. Choose the Lemokey L4 if you prioritize a firmer feel from the aluminum plate, quieter typing from upgraded acoustic foams, and easy dongle storage for travel. Both deliver identical wireless gaming performance and 4000 mAh battery life, so your decision should hinge on sound preference, layout needs, and accessory features.

Keychron Lemokey L3

  • +Polycarbonate plate provides a softer, more flexible typing feel compared to aluminum.
  • +Features a knob and dedicated macro column for quick access to custom commands.
  • +Supports ANSI, ISO, and JIS layout standards, appealing to international users.
  • +Available as a barebone kit for modders who want to supply their own switches and keycaps.
  • −No receiver storage compartment, increasing the risk of losing the 2.4 GHz dongle.
  • −Lacks the upgraded acoustic foam layers (IXPE, PET, EPDM) found in the L4 for sound dampening.
  • −Heavier than the L4 at 1976 g, making it less portable.

Keychron Lemokey L4

  • +Includes upgraded acoustic foams (IXPE, PET, EPDM) for reduced keystroke vibration and improved sound.
  • +Hidden magnetic receiver storage compartment on the back protects the 2.4 GHz dongle during travel.
  • +Aluminum plate provides a firmer, more rigid typing feel preferred by some users.
  • +Slightly lighter at 1858 g and more compact at 355.8 x 142 mm for better portability.
  • −Lacks a knob and macro column, limiting out-of-box shortcut options.
  • −Available only in ANSI layout, so users needing ISO or JIS must look elsewhere.
  • −Not offered as a barebone kit, reducing flexibility for modders to start from scratch.

Which Keyboard Is Better for Your Needs?

In gaming, both keyboards perform identically with the same 1000 Hz polling and gasket mount feel. For office use, the L4’s upgraded acoustic foams and receiver storage give it an edge in quietness and convenience. Programming favors the L3 because of its softer PC plate, knob, and wider layout support. Travel leans toward the L4 due to its integrated dongle storage and smaller footprint. Modders and content creators will appreciate the L3’s PC plate, barebone option, and macro column for deeper customization and workflow control.
