To connect music to home appliances, there are several ways.

First, you can use Bluetooth technology to wirelessly transfer music from your phone, tablet or computer to a Bluetooth-enabled stereo or headset.

Second, you can use an audio cable to connect a music device (such as an MP3 player or phone) to the audio input port of your sound system.

In addition, some TVs and sound systems also support wireless connection. You can transfer music from your device to your TV or stereo via Wi-Fi or AirPlay.

Finally, you can also use smart speakers (such as AmazonEcho or GoogleHome) to play music, which can be controlled by just voice commands. No matter which method you choose, you can easily connect music with home appliances and enjoy a high-quality music experience.
