At £42, this open-box FiiO BTR13 is a strong bargain in the current used market, sitting well below the 25th percentile of £48 and significantly under the median of £78 based on 316 recent GBP listings. For context, the BTR13 retails new for roughly £64, so buying it now at £42 means you’re securing a versatile Bluetooth/USB DAC and headphone amp for about 35% off retail while still getting a well-regarded device.
The BTR13 is notable for its thumb-sized form factor and three-way switching (PC/BT/PHONE), delivering solid power via its 4.4 mm balanced output (220 mW/channel) and aptX HD/LDAC support for high-quality streaming. It’s a favorite among budget-conscious enthusiasts who want portable LDAC performance without the bulk. Since this is an open-box unit, assume it’s essentially new with minimal wear, and unless accessories are missing, this is a clean buying opportunity at a price that rewards the buyer.

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.
