HiFi Bass FM Transmitter Bluetooth 5.3

Slim-profile FM transmitter engineered for seamless integration into UK-spec vehicles; Dimensions: 68 × 32 × 22 mm; Weight: 42 g; Material: flame-retardant ABS casing with reinforced USB port mounts; Audio system: stereo FM modulation with harmonic-rich bass extension activated by tactile bass boost button; Visual feedback: responsive LED bar that illuminates and pulses proportionally to audio energy — fully disableable via CH button hold; Charging system: independent regulation for USB-C (PD 20W) and USB-A (QC 18W), each maintaining full output even under thermal load; Wireless core: certified Bluetooth 5.3 controller with support for SBC and AAC codecs, ensuring compatibility with iOS and Android; Voice system: dual-mic array with CVC noise cancellation, optimised for speech intelligibility in moving vehicles. The HiFi stereo output avoids the thin, tinny character common in entry-level transmitters by preserving midrange detail alongside boosted bass — making podcasts, audiobooks and vocal-centric music equally enjoyable. Dual charging supports mixed-device households: e.g., an iPhone 14 charging at 20W while a Samsung Tab A charges at 15W (within QC 18W headroom). Bluetooth 5.3’s lower power draw extends adapter lifespan and reduces heat buildup — important in UK summer conditions where dashboard temperatures exceed 50°C. The microphone’s noise model was trained using real UK traffic audio samples (A-road, M25, city centre), not generic lab noise — resulting in superior rejection of diesel rattle and rain-on-roof frequencies. LED disable logic is hardware-level, not firmware-dependent, guaranteeing reliability across all vehicle electrical systems.
