Are you looking for a cheap way to make wired headphones wireless? At £18, this is a genuine bargain: it sits well below the £63 25th-percentile figure from six comparable sold listings, against a £176 median and £347 75th percentile. Even allowing for missing accessories, the price leaves plenty of room before it becomes merely fair value.
The BTR11 is a nicely practical little Bluetooth receiver, with LDAC, Bluetooth 5.3, a 3.5mm output, built-in microphone, clip and roughly 15-hour battery life. Its modest amplifier is especially well suited to IEMs and efficient portable headphones, rather than demanding high-impedance models. Check that it charges, pairs reliably, holds its battery and includes the essentials—particularly the charging cable and clip—but missing extras are hardly a deal-breaker at £18.

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.
