Item  Description

 

(1) wireless products use distance nothing more than to depend on two factors， the power of the transmitter and the receiver sensitivity of the receiver， and want to get farther distance is nothing more than increase the transmit power or improve receiver sensitivity. The X300 wireless receiver 2.4G dedicated omnidirectional antenna and optimize circuit design， a relatively normal Bluetooth headset circuit board antenna significantly improved receiver sensitivity， a relatively ordinary 10-meter range Bluetooth reception range up to 20meters，  we use the Iphone4S measured distance over 25 meters (2) Since the X300 is a wireless receiver， the use of distance depends primarily on Bluetooth transmitting equipment， power different device power there will be differences.(3) U the segment signal penetration is not good， so through the wall signal will significantly attenuated， 2.4G is the resonant frequency of water， human walked signal will be absorbed is a normal phenomenon.The said distance wireless products for LOS， open line of sight. 3) U the segment signal penetration is not good， so through the wall signal will significantly attenuated， 2.4G is the resonant frequency of water， human walked signal will be absorbed is a normal phenomenon. The said distance wireless products for LOS， open line of sight. (4) X300 wireless Bluetooth receiver， the use of 2.4G high sensitivity omni-directional antenna， the use of the environment， pay particular attention to as far away as possible from the same frequency wireless routers and other equipment， a strong power of the wireless router will interfere with the X300 signal reception， making deterioration of the reception， in order to ensure the reception， we measured to be better in the more than two meters away! (5) Due to the characteristics of low power consumption of the Bluetooth chip itself， does not receive audio data for a period of time will automatically enter a low-power standby mode to turn off the chip has its own internal CODEC audio data received CODEC automatically start at once， the process of this switch produce "scarred" sound， this sound characteristics of Bluetooth chips decision， not a product quality problem.
