The difference between wireless FM headphones and audio headphones

Wireless FM headphones: To work with the FM transmitter at the same time, built-in FM receiving circuit, working in the FM band (88-108MHZ), generally has the function of listening to FM (frequency modulation) broadcast.

When in use, the audio signal passes through the FM modulation circuit matched with the earphone, and is converted into a frequency modulated signal to be transmitted to the space. After the FM earphone receives the FM signal transmitted by the earphone (the receiving frequency of the earphone is adjusted before use, so that the receiving frequency and the transmitting frequency thereof are adjusted. The frequency of the device is consistent. After demodulation and other processing, the headphone speaker is pronounced by amplification.

Since the FM signal is a radio signal, wireless transmission is realized between the earphone and the transmitter. The larger the transmission power of the FM transmitter, the farther the transmission (listening) distance is.

The audio earphone is simple. Any earphone that can play audio processed by other circuits is an audio earphone.

It can be seen from the above that the main difference between the wireless FM headset and the audio headset is that one uses the FM radio to wirelessly transmit audio signals; the other is to transmit audio signals in other ways.
