What brand of headphones is tws?

tws is neither a brand nor a model, but a general term for wireless headphones, which is a type of headphones. TWS is the abbreviation of True Wireless Stereo in English, which means true wireless stereo. This technology is based on the development of Bluetooth chip technology. The application of TWS technology to the field of Bluetooth headsets gave birth to a new product - TWS Bluetooth headsets. TWS earphones do not require wires at all but connect and transmit via Bluetooth. At the same time, the left and right ears can be used independently, and their functions are richer.

#TWS earphones do not require wires at all but are connected and transmitted via Bluetooth. At the same time, the left and right ears can be used independently, and their functions are richer.

The principle of TWS earphones

Let’s talk about the principle first. In the past, the working principle of Bluetooth earphones was the underlying wireless signal module, protocol layer and application layer. This is really true. It is the same on Bluetooth wireless headsets, but in the past, the Bluetooth headsets with cables connected the two headphone units to the Bluetooth module through the cable. The Bluetooth signal was transmitted to the module and directly output the audio signal through the application layer, from the two headphone units. It can be said that the entire transmission is only the signals of the mobile phone's Bluetooth and the Bluetooth headset transmitting to each other.

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

Advantages of TWS earphones

Now that we have finished talking about the principles, let’s talk about the advantages of true wireless Bluetooth earphones. Because compared to wireless Bluetooth headsets, true wireless Bluetooth headsets directly subtract 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 scratches. It will make people feel very relaxed wherever they go; at the same time, the true wireless Bluetooth earphones can be made smaller, making it easier for users to carry them daily; the left and right units of the earphones can be directly inserted into the charging box (this is still Apple’s idea, everyone Everyone has learned it, but there is no doubt that this is currently the best solution for charging and carrying true wireless Bluetooth headsets), which not only improves battery life but also reduces the chance of loss.

In addition, there is another very important point about true wireless Bluetooth headsets, which is the future development potential. Although everyone will still find many shortcomings (we will talk about the shortcomings in a moment, they will never be absent), but we don’t know how far true wireless Bluetooth headsets will develop in the future, and we are full of expectations. When the Airpods generation is launched At that time, people thought that this was another product that Apple could not surpass within three years. However, just a few months later, major manufacturers have come up with products that are comparable to Airpods. Although the second generation of Airpods today maintains its leading edge, it is 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 achieve the comfortable operation of taking out the charging box and putting on the ears and it will automatically connect. This is very Amazing.

Disadvantages of TWS headsets

As for the shortcomings, the current true wireless Bluetooth headsets naturally have many unsatisfactory aspects, such as most True wireless Bluetooth headsets are not yet able to achieve real-time sound transmission. The most intuitive experience is: when we open "Peace Elite" and shoot at the wall, the gunshot will not sound until the gun is fired. This is the sound delay. Now Airpods The second generation uses Bluetooth 5.0 to solve this problem, but many true wireless Bluetooth headsets using 5.0 still have this problem.

The second is the poor sound quality, because the last wire is cut off and all data is transmitted wirelessly, which will definitely have an impact on the sound quality. At the same time, because such a design costs high, Therefore, the sound quality of wireless Bluetooth headsets at the same price level has a certain advantage over true wireless Bluetooth headsets; the third is short battery life, which is an inevitable problem caused by small size. Most products have a battery life of ten hours or less. , if you want to improve the battery life, you can only stuff it into a charging box with the same small capacity.

The main features of TWS earphones are:

1. True wireless, eliminating the trouble of tangled earphone wires

ws Bluetooth earphones do not require a wired connection. The left and right earphones, which get rid of the wired constraints of traditional earphones, form a stereo system by Bluetooth, which improves the ability to listen to songs, talk, and wear. If you add professional sound pickup technology, intelligent noise reduction technology, AI algorithm noise reduction technology, etc., you can achieve a perfect sound experience. Wear it on your ears to make voice calls, make video calls, enjoy music, climb mountains, and drive safely without any restrictions.

2. Binaural stereo sound, improve sound quality and call quality

From a product perspective, the audio and video experience is the most popular among TWS headsets. Therefore, the noise cancellation function is an indispensable technology for TWS.

3. Multiple perception, improve user experience, and produce intelligent voice. In the era of crazy development in 2018, TWS earphones have experienced the path of becoming semi-intelligent earphones. Many Bluetooth chips have been upgraded to version 5.0, with built-in serial flash memory, which can more flexibly upgrade customers' software. It can also provide support for transplanting third-party software's original ecology and content (including financial updates, sports information, etc.). Open this port. , in fact it is very possible in this part of the content.

4. Comfortable to wear, easy to use and easy to carry.

Expand knowledge:

The main reasons why Bluetooth headsets have poor sound quality and cannot keep up with heating devices are Two:

1. Bluetooth headsets need to consider the insufficient instantaneous output current that can provide endurance distance. In other words, what we often call insufficient thrust and dynamic transition may have certain deficiencies.

2. Many Bluetooth headsets use the default SBC transmission protocol. This protocol deteriorates the sound quality. Both AC and APTX can transmit 320k audio. So if not a deep audiophile. It's difficult to tell whether the sound quality is good or bad without comparing A-B.
