From Airpods first generation to today’s assortments of wireless headphone options, true wireless Bluetooth headphones have gradually replaced the previous integrated Bluetooth headsets, and becomes people’s new buying decision. However, can the headset replace the previous Bluetooth headset? What to know about it? This blog covers everything you need to know, including the principle and the advantages and disadvantages of true wireless Bluetooth headphones.

The principle of TWS headset

Let’s talk about the principle first. In the past, the working principle of Bluetooth headsets was the underlying wireless signal module, protocol layer, and application layer. This is the same for true Bluetooth wireless headsets. However, Bluetooth headsets with cables used to connect two headset units to the Bluetooth module through a cable. The Bluetooth signal is transmitted to the module and the audio signal is directly output through the application layer. The audio signal is sent from the two headset units. It can be said that the entire transmission is only the signal of the mobile phone Bluetooth and the Bluetooth headset.

But the design of the true wireless Bluetooth headset is different. It has two headsets, a primary and a secondary headset. The Bluetooth module in the primary headset is used to connect to the mobile phone, and the secondary headset is connected to the primary headset. In other words, the wireless signal transmission of true wireless Bluetooth headsets is actually divided into two ends, mobile phone to main headset, main headset to secondary headset. Airpods uses this approach, but now Qualcomm has also joined the army and launched Bluetooth 5.0. The dual headset direct connection solution means that true wireless Bluetooth headsets do not need to be divided into primary and secondary headsets, and left and right ears can operate independently.

Advantages of TWS headphones

Let's continue to talk about the advantages of true wireless Bluetooth headsets. Compared with the wireless Bluetooth headset, the true wireless Bluetooth headset directly subtracts the only line between the two units, so the user's wearing experience will be easier, and the overall design will be more convenient. There is no stethoscope effect and no need to worry about scratching. Wherever it goes, it will make people feel very relaxed; at the same time, the true wireless Bluetooth headset can make the volume smaller, and the user's daily carrying will be easier; the left and right units of the headset can be directly inserted into the charging box, which improves battery life while reducing The chance of loss.

In addition to true wireless Bluetooth headsets, there is another very important point, that is the future development potential. Although everyone will still pick out many shortcomings, we do not know how far true wireless Bluetooth headsets will develop in the future, and we are full of expectations. When the Airpods generation was launched, people felt that this was another Apple that could not surpass in three years. However, only a few months later, major manufacturers have pulled out products comparable to Airpods. Although the second generation of Airpods maintains a leading edge, they are also being chased by other manufacturers. We don’t know what kind of technology this design will produce in the future, but now any manufacturer can take it out of the charging box, The comfortable operation that the ears are automatically connected is amazing.

Disadvantages of TWS headphones

As for the disadvantages, the current true wireless Bluetooth headsets naturally have many unsatisfactory aspects. For example, most true wireless Bluetooth headsets cannot achieve real-time sound transmission. The most intuitive experience: the sound in the headset and the The picture is out of sync. This is the sound delay. Now Airpods II uses Bluetooth 5.0 to solve this problem, but many true wireless Bluetooth headsets that use 5.0 still have this problem.

The second is the poor sound quality. Because the last line of its own is cut off, all data transmission is transmitted wirelessly, which will definitely affect the sound quality. At the same time, because of the high cost of such a design, wireless Bluetooth at the same price Compared with true wireless Bluetooth headsets, headsets have a certain leading edge in sound quality;

The third is the short battery life, which is an inevitable problem caused by the small size. Most products have a battery life of ten hours or less. If you want to increase the battery life, you can only put it into a charging box with the same capacity.

Conclusion

To sum up, the current true wireless Bluetooth headset is the future trend, but it has not yet become a truly mature product. Most manufacturers are still groping, and chip manufacturers are constantly looking for feasible solutions. One day in the future, it is almost inevitable that all manufacturers can make excellent products like Airpods II. Then we can enjoy the real wireless life.
