The popularity of wireless products can be traced back to two or three years ago, when 2.4G wireless headsets dropped to 99 yuan. But as far as the current wireless market is concerned, Bluetooth is the absolute mainstream position. Let alone how hot the Bluetooth headset market is, first-tier multimedia speaker manufacturers such as Edifier, Hivi, Microlab, etc. have stepped into the manufacturing of Bluetooth speaker products. If the leading companies in an industry all act together, the future development direction of the industry must follow them.

    As mentioned earlier, the popularity of wireless started from 2.4G, so why did Bluetooth eventually occupy the mainstream? Can Bluetooth be singled out for 2.4G? In fact, in comparison, Bluetooth technology has its unique advantages.

     In view of the maturity of Bluetooth technology, Bluetooth is no longer the inconvenient guy in the early years. Early Bluetooth was very picky about Bluetooth devices due to compatibility issues. Not every mobile phone with Bluetooth function can connect to Bluetooth speakers; not every device with Bluetooth function can transfer files, so Bluetooth is limited to The application of Bluetooth headsets is narrow.

    Up to now, the Bluetooth function has been very powerful. The higher version of the Bluetooth protocol supports the Advanced Audio Transmission Protocol (A2DP), that is, through the Bluetooth device itself, the playback device is controlled, including but not limited to play, pause, high volume, low volume, previous song, next song, etc. , Fully realized wireless control. Of course, Bluetooth can even be seamlessly connected and switched. When the device enters the work area, it can automatically switch the currently matched Bluetooth device, and it is seamless, and the user experience is greatly improved.

  For a specific user population, Bluetooth technology can also play a role in saving investment. The new iPhone5 uses a small DOCK interface, which is completely inconsistent with the old interface. Then all Apple DOCK speakers on the market are scrapped because they are not compatible with the new iPhone; but if these DOCK speakers use Bluetooth connection In this way, there is no such problem, only a wireless connection is needed, not a real physical connection, which greatly saves the user's investment.

    In addition, due to the addition of NFC technology, the Bluetooth pairing method is more simplified. You only need to bring the Bluetooth mobile phone close to the Bluetooth speaker, and the pairing process is completed in a short time, which is very convenient to use.

     Compared with other wireless carrier methods, Bluetooth and 2.4G are currently the two most mainstream, and Bluetooth is the most compatible of these two methods. Bluetooth does not need a transmitter, that is, mainstream digital products have built-in Bluetooth functions, and only need to be connected to use, unlike 2.4G or FM, infrared and other wireless methods, which require a transmitter, it is very convenient to use . Suppose we have invested in a Bluetooth device, which can be used in any product that supports Bluetooth. This is cross-platform, cross-system, not restricted by other factors, and has strong compatibility.

    The use of Bluetooth is very convenient, you only need to pair it when you connect for the first time. The Bluetooth protocol with better compatibility and higher version at present can complete the pairing without even entering the passcode. Not only that, but Bluetooth products can even automatically connect within the working range, eliminating the trouble of manual connection, and it is indeed very convenient to use. These advantages are not available in 2.4G equipment.
