At US$65, this is a strong deal against your database anchor: it lands below the 25th percentile of US$68 and well under the median of US$107, so it reads as a bargain rather than just “okay” pricing. For a used desktop DAC/headphone amp, that’s exactly where a buyer wants to see a clean listing.
What makes it worthwhile is the E07K’s reputation as a simple, dependable USB DAC/amp with enough power for efficient headphones and a straightforward plug-and-play setup. If it powers up cleanly, holds charge if used portably, and includes the right cable(s), this is the kind of older FiiO piece that still makes sense as a budget desktop or starter rig buy.

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.
