A wireless audio adapter with Bluetooth 5.0 serves as a versatile bridge between wired and wireless audio devices. It can function as both a receiver (to stream audio to wired speakers/headphones) and a transmitter (to send audio from non-Bluetooth sources like TVs or old stereos). Key features include FM radio, AUX/3.5mm/RCA inputs, optical support, hands-free calling, and NFC pairing.
