There are some obstacles in using wireless products in our daily life. Sometimes it may be a problem of the product itself, but it may be that the construction worker does not notice some influencing factors during the installation process, which will lead to the failure of the wireless product. When purchasing wireless products, radio signals often see different wireless frequency bands such as 433MHz, 868MHz, 902MHz or 2.4GHz. The wireless signal transmission loss is inversely proportional to the wavelength, which is proportional to the frequency. The higher the frequency, the greater the loss. Since many technologies are based on the 2.4 GHz band, such as Bluetooth, WiFi, Zigbee, etc., the frequency band is crowded and causes many interferences. Therefore, a complex anti-interference mechanism is required, and multiple wireless signals are repeatedly transmitted, and the following is relatively less crowded and anti-interference below 1 GHz. The mechanism is simpler. In addition, in order to achieve the same transmission distance below 868 GHz, 2.4 GHz needs to increase the transmission power. Therefore, the power consumption of a 2.4 GHz device is much larger than that of 1 GHz or less. Therefore, under the same conditions, the transmission distance in the frequency band below 868 GHz is farther than 2.4 GHz, and the penetration is strong. Low power consumption is required, transmission distance is long, and the amount of data transmitted is small, and products below 868 GHz are selected. (such as in building control) First, we must know the characteristics of wireless attenuation. Below are some guidelines for wireless product installation. It is very important to transmit the angle of the signal through the wall. The effective wall thickness (signal attenuation) varies with this angle. Signals should be transmitted directly through the wall as much as possible. TIps: Avoid unfavorable penetration angles by locating the transmit/receive antenna or using a repeater. For example, AdvancedDevices two-way dimmer 丶 wireless switch use When using equipment with an internal receiving antenna, the equipment should not be mounted on the same wall as the transmitter. Near the wall, radio waves are likely to be disturbed to disperse or reflect. Therefore, the position of the antenna must be on an opposite or connected wall. When using a device with an external antenna, the ideal antenna mounting location is the center of the room, and the antenna is at least 10 to 15 cm from the corner or concrete ceiling. TIps: Avoid radio propagation along walls (assuming a narrow room). The distance between the EnOcean receiver and other transmitters (eg GSM / DECT / WLAN) or high frequency interference sources (computer, audio / video equipment) should be at least 50 cm. However, the EnOcean transmitter can be installed next to any other high frequency transmitter without any problems. TIps: The distance between the EnOcean receiver and the different types of high frequency transmitters is at least 50 cm. The position of the transmitter is not important. For esports headsets, USB jack is used, the traditional 3.5mm headphone jack design does not appear acoustic positioning sense, pay more attention to surround sound, design field is different. Wired Game Headphones definitely have lower latency than Wireless Gaming Headphone for Gaming Headphones. Usually use magnetic ring shielding, tensile line design.
The online esports headphones are mainly USB ports, and the independent sound card design is mainly used to create virtual sound effects and positioning effects. The use of esports headphones will inevitably appear cool light effect, headset light, microphone light, RGB light belong to the current mainstream design.

Common esports headsets use an all-inclusive design,which has the advantage of isolating ambient noise.The headband part of the earphone will be different from each type of earphone.The strength of the headband will determine whether it will compress the head after wearing, whether it is breathable and other details.
Common esports headphones will be equipped with switch adjustment. When choosing, you can give priority to products that support 7.1 sound channel, consider supporting light switching, and consider supporting acoustic positioning function. Usually tap earphones will also come with a microphone design. Consider models with high sensitivity and acoustic noise reduction.
