Bluetooth 5.0 TX RX Mini Audio Adapter

Physical size: 2.2 × 5.9 × 1.2 cm (0.86 × 2.32 × 0.47 in); lightweight construction ensures easy portability and unobtrusive placement. Equipped with a built-in rechargeable Li-polymer battery providing up to 4 hours of continuous operation. Bluetooth version: 5.0 — supporting enhanced range, lower power draw, and improved multipoint resilience. Single 3.5mm aux interface serves both input and output functions. Compatible with all mainstream Bluetooth audio devices (headphones, earbuds, speakers), as well as non-Bluetooth audio hardware featuring standard line-level aux ports — including UK-market TVs, desktop computers, car stereos, portable media players, and home amplifiers. Transmitter function enables audio streaming *from* fixed devices (e.g., Sky Q box, DVD player, PC) to wireless headphones or speakers — ideal for shared households or noise-sensitive environments. Receiver function allows audio streaming *to* fixed audio systems (e.g., DAB radio with aux-in, older car head unit) from mobile devices — enabling hands-free navigation prompts, podcast playback, or Spotify control without cables. Pairing initiated via tactile central button; status indicated by simple LED behaviour. Designed for practical UK/EU usage: tested with common regional devices (e.g., Sony Bravia TVs, JBL Flip speakers, iPhone 12–15, Samsung Galaxy A-series, Ford SYNC systems), with emphasis on reliability over marketing claims — no hidden firmware locks, no region-based restrictions, no mandatory cloud services.
