The Keychron K2 is the best wireless mechanical keyboard under $100. It packs Bluetooth 5.1, hot-swappable switches (V2), and a compact 75% layout into a well-built aluminum frame. After 4 weeks of daily typing across Mac and Windows, it earns its position as the top budget keyboard recommendation. The Gateron Brown switches provide a satisfying tactile bump without being disruptive in shared spaces.
