People who have high requirements for sound, that is, audiophiles, naturally do not choose wireless transmission of audio. Whether it is Bluetooth or FM, the signal is first compressed and converted into a radio signal and then transmitted to the receiver. The signal is converted and decoded and compressed, and the loss of the signal will occur in the process of signal compression, transmission, decompression and transcoding. Although it may be possible to add sound beautification hardware or software to process the sound It doesn't look so authentic.

For example, A and B are 5 meters away from each other, A is the sink (receiving signal sound), B is the faucet (signal transmitter), add water to the sink, and use the water pipe (transmission signal line) as long as there is no leakage in the middle of the water pipe. Do it without loss, no matter what? You can only change the angle of the faucet, and increase the pressure to spray it, but in the process of spraying, a lot of water will be wasted!

Of course, if the sound requirements are not particularly high, you can consider wireless speakers. After all, it will save a lot of cumbersome cables and the trouble of drilling holes in your beloved house for these cables. However, in the future, wireless audio is inevitable for future development, which will reduce the cost of installation and debugging, and the cost of wire is not a small expense.
