The FiiO KA5 is a USB DAC/amp dongle with dual Cirrus Logic CS43198 chips, an OLED screen with physical buttons, and 3.5mm plus 4.4mm balanced outputs rated up to 265mW per channel into 32Ω. It suits phone and laptop listeners who want on-device controls and both USB-C and Lightning cables in one kit.
Who the FiiO KA5 is for
Balanced and single-ended headphones: The 4.4mm output is rated at 265mW per channel into 32Ω for 16–300Ω loads, and the 3.5mm jack at 122mW per channel for 16–150Ω.
Android and iPhone owners: USB-C to USB-C and USB-C to Lightning OTG cables both come in the box, so the detachable-cable dongle moves between an Android phone and a Lightning iPhone.
Hands-on tweakers: The OLED screen and buttons set high or low gain, 5 digital filters, L/R balance and screen flip without an app, and FiiO Control adds app control on Android.
Consoles and external DACs: A UAC 1.0 mode, entered by holding the multifunction key while connecting, works with devices such as the Nintendo Switch and PS5, and the 3.5mm jack can switch to coaxial S/PDIF out through a 3.5mm-to-RCA coaxial cable sold separately.
Skip it if: you need MQA or iPhone app control: FiiO says the KA5 does not decode MQA, FiiO Control supports it only on Android, and an iPhone may stutter at extreme volume because of its limited USB power.
Formats: PCM up to 32-bit/768kHz; DSD64/128/256; coaxial out up to 32-bit/192kHz; no MQA
Display and controls: OLED screen; buttons for menu, settings, volume and track skip
Connection: USB-C port with detachable cable; UAC 2.0 and UAC 1.0 modes
In the box: USB-C to USB-C OTG cable, USB-C to Lightning OTG cable, USB-A male to USB-C female adapter, manual
Size, weight and colors: About 56.3 × 22 × 12mm and 19g without cable; Black or White
