Some of you may be wondering, what's the difference between a bluetooth headset and a wireless headset? Many friends will say that most bluetooth headsets are wireless, but traditional in-ear bluetooth headsets still have cables on both sides of the cell to transmit audio signals. In other words, both sides of the in-ear bluetooth headset with cable can work at the same time, just like a bluetooth speaker. The in-ear bluetooth headset can transmit through the cable, so that both ears can produce sound steadily and synchronously.
The true · wireless bluetooth headsets, represented by AirPods, are further subtracted, meaning they work differently. There are main and secondary earphones in real wireless bluetooth earphones. When connecting, transmitter devices (mobile phone, tablet computer, music player with bluetooth output, etc.) should be connected with the main earphone first, and then connect with the secondary earphone after confirming the connection. Only after the connection is completed, can it work normally.
That is to say, compared with the traditional "wireless earphone", the connection between the real wireless earphone is not only the signal transmission between the earphone and the signal transmitter, but also the wireless connection between the main and secondary earphones. Compared with the traditional "wireless earphone", the real wireless earphone has a more complex structure, higher transmission requirements, and higher power consumption. The influence of these elements on the final sound effect is also more obvious. The general phenomenon is that the sound quality of the real wireless earphone is slightly worse than that of the bluetooth earphone of the same price. With all the distractions, why make real wireless headphones?
Traditional in-ear bluetooth headset is have a wire connected, which makes them have escaped with the physical connection between sound source, but the wire between two headphones, when wear or bring some interference, a typical example: movement, especially in sports physical needs traditional bluetooth headset is always unable to deal with "auscultation effect". Of course, it is not limited to this. In addition, the middle line is missing. In terms of gameplay and user freedom, the real wireless headset will significantly improve the experience of this part.
But there are problems with the real wireless bluetooth headsets
In this case, I believe that many manufacturers will follow up to launch TWS products. The market that is more interested in this kind of product form may be in foreign countries, or it may be that cockerel attaches more importance to sports and has more time and opportunities for sports, right? However, as the editor mentioned above, it is not easy to solve the problem of making real wireless earphones to match the original in-ear bluetooth earphones.
There's a popular saying in the audio world, "play the video before you play HiFi." "Electricity" for bluetooth headsets is not only related to the battery life, but also means whether it can provide enough power to support the normal work of the internal circuit. In addition to the original signal receiving module and most of the code playback, the real wireless earphone also has a circuit connecting the main and secondary earphones. Three parts work at the same time, the requirements for the battery is also correspondingly increased. Therefore, we can all see that the single use time of real wireless earphones will not be too long, most of which are about two hours, and they should be basically used with storage boxes containing batteries, so as to ensure enough battery life.
