Multifunctional Bluetooth Cassette Adapter

This multifunctional car cassette adapter combines Bluetooth 5.0 wireless audio streaming, FM radio reception, and physical tape playback in a single ISO-standard cassette form factor. Built from high-grade ABS polymer, it weighs 85 g and integrates a low-power Bluetooth module with an effective line-of-sight range of up to 10 metres. It connects directly to the car’s cassette deck without modification — no soldering, no splicing, no permanent installation. Audio output is delivered via the deck’s original magnetic head interface, preserving signal fidelity and eliminating the background hiss or frequency roll-off typical of FM transmitters. The included micro-USB data cable allows for potential firmware upgrades, and the English manual provides clear step-by-step guidance for initial pairing, source selection (BT/Radio/Tape), and volume calibration.
