Two Cirrus Logic CS43131 DACs and two low-noise SGM8262 amplifiers deliver up to 550mW from a 4.4mm balanced output, alongside a 3.5mm headset socket, and play PCM up to 384kHz\/32-bit and DSD256. It is also a USB hub for your mouse and drives, with a gasket-mounted, hot-swappable typing feel, Gateron G Pro 3.0 switches, a stepless volume knob and an aluminium-magnesium alloy case.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/FIIOKB3-HIFI_1000x549_23a26be5-d2d9-4fde-9350-13520a437ca8.jpg?v=1767194441\" alt=\"FiiO KB3 keyboard with RGB lighting and headphones plugged in\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eA desktop DAC\/amp in your keyboard\u003c\/h3\u003e\n\u003cp\u003ePlug the KB3 HiFi into your computer and it becomes your sound card. Its “2+2” combination of two CS43131 DACs and two SGM8262 op-amps gives power comparable to a desktop amp: 550mW per channel into 32Ω from the 4.4mm balanced output and 170mW from the 3.5mm, with a 122dB signal-to-noise ratio, so it drives anything from earphones to full-size headphones. It decodes PCM up to 32-bit\/384kHz and DSD256 to bring out the detail in your music.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0960\/3199\/8339\/files\/FIIOKB3-HIFI_790x790_b67b3d24-88cc-4584-afce-659402533938.jpg?v=1767194455\" alt=\"FiiO KB3 3.5mm and 4.4mm headphone sockets and USB ports\" loading=\"lazy\"\u003e\u003c\/p\u003e\n\u003ch3\u003eDriver-free, or ASIO with FiiO’s driver\u003c\/h3\u003e\n\u003cp\u003eUSB audio works without a driver on Windows 10 and later and on macOS.
