The E10K Olympus 2 has long been a well-regarded entry-level USB DAC/amp: compact, sturdy, and more capable than its modest size suggests. At US$40, this is a genuine bargain—well below your comparable-sales 25th percentile of US$85 and far under the US$236 median.
It is a particularly useful desktop companion for efficient headphones, offering clean USB conversion, a handy bass-boost switch, line output, coaxial digital pass-through, and around 200 mW into 32 ohms. The 24-bit/96 kHz limit is hardly a practical drawback for ordinary listening, though it is not intended for demanding high-impedance headphones. Confirm that the volume control, USB connection, headphone output, and switches work, and that a suitable Micro USB cable is included; even allowing for a replacement cable, this remains an easy buy at the asking price.

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.
