Wireless Audio Transmitter and Receiver

A wireless audio transmitter and receiver system sends sound without cables, using radio waves (like Bluetooth or 2.4GHz) to connect devices, with the transmitter sending audio from a source (TV, phone) and the receiver picking it up for speakers or headphones, often as a combined 2-in-1 unit for flexibility in home audio, car stereos, or professional setups. They work by modulating sound onto a carrier frequency, with advanced models offering low-latency codecs (aptX) for synchronized audio.
