This is a strong deal at £22 GBP. It sits well below the £63 GBP 25th-percentile figure from six recent comparable sales, making it a genuine bargain rather than merely a fair ask. The opened box is the only slight qualification, but at this level there is plenty of value even if the packaging is not pristine.
The BTR11 is a very useful little Bluetooth receiver for turning wired headphones or IEMs into wireless ones. It offers Bluetooth 5.3 with LDAC, a 3.5mm output, a built-in amplifier, multipoint pairing, microphone support, and up to 15 hours’ battery life. Its compact clip-on design is especially handy for commuting, and the output is well suited to efficient headphones and earphones. Check that the charging cable and clip are present, then buy with confidence.

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.
