The BTR15 has earned a strong reputation as a compact, genuinely capable Bluetooth DAC/amp, and GBP 83 is a strong deal. Your six comparable sold listings put the market median at GBP 176, with the 25th percentile at GBP 63, so this sits comfortably in bargain territory despite the minor defect.
Its appeal is the unusually complete feature set: LDAC and other modern codecs, USB DAC operation, a clear display, plus both 3.5mm and 4.4mm outputs. The balanced socket gives it considerably more headroom for suitable headphones, while the small size makes it a very practical phone or laptop companion. Before buying, establish exactly what “minor defect” means and confirm charging, Bluetooth pairing, both outputs, buttons, and screen operation; if those check out, this is an excellent low-risk entry into a very useful little unit.

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.
