At US$60, this sits well below the US$105 median and even under the US$64 25th percentile, so it reads as a strong buy in the current used market. Against a typical spread up to US$199 at the 75th percentile, this is priced on the low side without feeling unrealistic.
That makes sense for a compact USB DAC/amp that’s long been popular as an easy desktop or travel upgrade: it gives you cleaner output and more drive than a laptop or phone jack, and the K3 line is generally liked for being simple, reliable, and good-sounding for the money. The missing USB cable is a minor knock, not a dealbreaker, and at this price the main thing to confirm is that it powers up cleanly and the inputs/outputs work as expected.

Fiio, founded in 2007 in Guangzhou, China, emerged as a specialist in portable audio gear, initially crafting components like speakers for brands such as Meizu before launching its own lineup. The name blends "Fi" from hi-fi fidelity with "iO" symbolizing digital one's and zeros, evoking authentic sound and modern convenience, while its Chinese rendering "飞傲" conveys innovative vitality. From modest beginnings, the company expanded into a 15,000-square-meter industrial complex by 2022, solidifying its role as a prolific developer of music-centric electronics.
The brand excels across a broad spectrum of portable and desktop audio categories, with flagship strengths in high-resolution digital audio players (DAPs), USB DACs, portable headphone amplifiers, and in-ear monitors. Its portfolio also encompasses cables, desktop amps, and select speakers, prioritizing versatile, high-performance solutions for on-the-go and home listening without venturing into turntables or large-scale hi-fi systems.
Fiio occupies a commanding mid-tier position in the global audiophile market, renowned for delivering premium sound quality at accessible prices that punch above their weight. Praised by enthusiasts for reliability and value, it appeals to discerning buyers seeking refined portable setups over luxury excess, backed by worldwide distribution and a track record of user-acclaimed innovations.
