How wireless invisible headphones work

Nowadays, the basic configuration popular among users is equipped with mobile phones, so it is mainly the mobile phones that are blocked or detected. Currently, the mobile phone shielding system on the market mainly interferes with the three frequency ranges of GSM900MHz, GSM1800MHz and CDMA2000MHz; The detection range is generally from 100MHz to 2600MHz. The anti-detection anti-shielding wireless transmitter operates at a frequency of 200-400 MHz, so the mobile phone shielding system is ineffective for this device, and since the device is a one-way transmission system, the mobile-type receiving terminal does not transmit signals to the outside, and is always in the receiving state, so Dogs can't be found.
