Timing matters little here: the BTR11 is a recent, still-current budget receiver rather than an obsolete generation. At £22, though, it is an emphatic bargain—well below the £63 25th-percentile comparable price and dramatically under the £176 median. Even allowing for some variation in listings, this is strong-buy territory.
The appeal is straightforward: Bluetooth 5.3, LDAC support, a clean 3.5mm output, low output impedance and enough power for most IEMs and efficient headphones. Battery life is around 15 hours on AAC, or roughly 8.5 hours with LDAC, and the opened box should mean little if the unit is unused. Check that the charging cable and clip are present, then test pairing, battery life and the 3.5mm socket; otherwise, this looks like an easy recommendation at £22.

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.
