What are the unique features of wireless headphones?
A wireless headset generally refers to a headset system that transmits signals by infrared rays, and a cordless headset refers to a headset system that uses radio waves to transmit signals. The working frequency of infrared earphones ranges from a few KHz to a few MHz, and the effective distance is about 10 meters. The earphones must be within the visual range; most cordless earphones work in UHF with a transmission range of up to 100 meters and can bypass obstacles. Two or more wireless/cordless earphones may interfere with each other, so when choosing them, it is best to choose a variety with multiple operating frequencies. For cordless earphones, the possibility of interference when working on UHF is less than that on VHF. Both of these headphones have background noise, and the higher-end models have adopted noise reduction technology. Also note that the battery life of the wireless/cordless headset should generally not be higher than 8 hours.
