With the continuous improvement of people's living standards, more and more users began to pursue their own private space, although the trend of wireless speaker products more and more obvious, but this is just for convenience and boxes placed at the convenience of the decoration, The individual is still a private space violated. So, is an important trend in the future development of the field of wireless audio headset products: unrestrained listening environment is what we care about the most.
Current wireless transmission technology including FM, RF, infrared, and is now more popular 2.4G technology. FM most fatal flaw is not strong confidentiality, generally poor sound quality, the highest 22KHz sampling rate is called "radio quality";
Infrared high point requirements, we are very likely to experience slightly off angle infrared remote control operation can not be performed. Their disadvantage is obvious.
The 2.4G technology can not only avoid the above drawbacks, it also has high security, small size, low power consumption, transmission distance, two-way duplex, large bandwidth, etc., become the best solution with a wireless headset. The use of 2.4G and 2.4G technology Bluetooth headset headphones have their own advantages and disadvantages do what? Who are the best options? We compare.
Bluetooth technology, which is a technique based on 2.4G wireless transmission protocol, due to the different protocols used, it is distinguished from other techniques 2.4G technology called Bluetooth.
For now, the most widely used application of Bluetooth technology is a Bluetooth headset. Since most mobile phones have integrated Bluetooth, and some MP3 audio products also integrates a Bluetooth module, so widely Bluetooth headset "mass base," low cost.
Because of the unique advantages of this Bluetooth headset, so most of the Bluetooth wireless devices it does not need to set the transmitter, and the receiver is the only Bluetooth headset can work, the cost is reduced; secondly, Bluetooth headsets confidentiality good, this point is 2.4G frequency characteristics of the decision, it is not likely to cause hopping mean, harmonic and tapped. Finally, the Bluetooth headset is now quite mature, the hundred or so you can purchase good quality Bluetooth headset, the higher cost.
