As a digital product that is a must-have for today's young people, Bluetooth earphones have many variations so that people are confused about choosing. So how do we choose a better Bluetooth earphone but in a similar price range?

3 Key Points:

1. Fast and stable connection

2. Better sound quality

3. Low latency

➹ Connection Stability

If the bluetooth earphone connection is disconnected during use, it indicates that the bluetooth connection of the earphone is unstable. Mostly caused by objects blocking or interfering with the signal. For example, some metal objects can affect the bluetooth connection.

So you need to choose a bluetooth earphone with high anti-signal interference.

At present, bluetooth earphones are generally divided into 2 versions, namely bluetooth 4.0 and 5.0. Compared with bluetooth 4.2, bluetooth 5.0 not only improves anti-interference, but also greatly reduces power consumption. It can increase the data transmission speed by 2 times, from 1Mbps to 2Mbps, and the transmission distance is also increased by 4 times. In theory, it can reach a distance of 300 meters. If your house is very large, you don't need to worry about disconnection.

Bluetooth with different versions will follow the previous version. For example, if your phone supports Bluetooth 4.2 and your Bluetooth earphone supports Bluetooth 5.0, then after connecting, the Bluetooth 4.2 version will be used.

Now it has been gradually applied in the bluetooth earphone market, products using bluetooth 5.2 will have faster and more stable connection over long distances, lower power consumption, lower latency and improved sound quality.

➹ Sound Quality

After the sound is transmitted from the mobile phone to the earphone, the sound quality will be lost, which is related to the audio decoding protocol supported by the earphone.

The current common encoding methods include SBC (the most common), AAC, aptX, and LDAC, in real experience, the difference in sound quality between them is very large.

When measuring this protocol, we can judge from 2 parameters of bluetooth audio sampling rate and bluetooth audio digit. The higher the value, the better the effect of sound transmission quality.

iPhone only supports SBC and AAC encoding technology, and both are supported by almost all Bluetooth earphones, so there is no need to worry about the encoding used when choosing earphones.

For Android 8.0 and above, in addition to supporting SBC and AAC, it also supports aptX and LDAC.

Qualcomm's aptX protocol series can compress audio files without affecting the achievement of higher sound quality, which is the right choice for now.

➹Low Latency

With higher chip quality and Bluetooth version, and the corresponding encoding method can make the latency lower. However, with the increase in configuration, the price of the earphone will definitely increase. Among them, earphones with aptX encoding also have advantages in delay issues, and also have Qualcomm chips, so they can be a priority feature.

A little knowledge: Because Bluetooth transmission is in the 2.4Ghz frequency band and WiFi on the cellphone is also at 2.4Ghz, there will be a little interference with Bluetooth transmission. So it is recommended to change the cellular network or WiFi band to 5G when playing games.

In addition to the 3 important points above for choosing earphones, the appearance and long battery life are also important, so choosing a trusted brand will certainly make you worry-free~
