This is a massive buyer’s opportunity in the entry-level DAC/amp category, as the US$25 asking price is a genuine bargain that sits far below the 25th percentile of US$64 for used FiiO E10K units. Based on our database of 311 recent comparable USD listings, the median used price is US$105, with the 75th percentile at US$179, meaning this listing is roughly 60% cheaper than the typical floor for these items. You are effectively paying a fraction of what even the most budget-conscious buyers usually spend for this specific model.
The FiiO E10K Olympus 2 remains a well-regarded favorite for its sturdy metal build, 200mW output at 32 ohms, and clean bass boost that drives most desktop and portable headphones with authority. Its newer PCM5102 DAC chip and improved amplification stage offer a noticeable upgrade over the original E10K, delivering lower noise and better transient response. At US$25, even if the unit lacks original accessories or shows minor wear, the price-to-performance ratio is unbeatable, making this a clear buying opportunity for anyone needing a reliable, affordable USB DAC/amp.

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.
