The E10K Olympus 2 has a strong reputation as a compact, no-nonsense entry-level USB DAC/headphone amp, and £31 is a genuine bargain. Your comparable sales put the median at £276 and the 25th percentile at £59, so this sits comfortably below even the lower quartile—excellent value if it is working properly.
It remains useful for desktop listening: USB-powered, simple to run, with a clean line output, coaxial digital pass-through, gain and bass-boost switches, and enough output for many headphones, including some 250-ohm models. Original packaging is a welcome bonus and makes the listing more attractive for resale. At this price, simply confirm that the micro-USB connection, volume control, headphone output and supplied cable function correctly; there is little reason to overthink the purchase if they do.

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.
