Let’s talk about stability first

One of the most important differences between Bluetooth and wired headsets is stability and latency.

Bluetooth headsets with poor stability will often be disconnected. When there are many other Bluetooth devices around, it will also produce zrazila noise. Friends who have used Bluetooth headsets must have encountered it.

As for the delay issue, no one would expect that when they were “eating chicken”, the avatar box would only hear the gunshot for two seconds; or the second subtitle disappeared when watching the video, and the first line was just finished. .

To improve stability and reduce latency, you have to use stronger Bluetooth technology.

Not long ago, SIG (Bluetooth Official Organization) announced the abandonment of Bluetooth 4.1 and below.

Therefore, the mainstream wireless headsets now mainly have two versions, Bluetooth 4.2 and Bluetooth 5.0.

Compared with 4.2, Bluetooth 5.0 has a transmission rate twice as fast. The transmission distance has been expanded four times while reducing power consumption and saving power, and its anti-interference ability has also been enhanced.

When purchasing a wireless Bluetooth headset, the stability and low latency of the headset that supports Bluetooth 5.0 will be better than that of 4.2.

Fortunately, models after iPhone 8 and Android phones equipped with Qualcomm Snapdragon or Huawei Kirin processors in the past two years support Bluetooth 5.0.

If your phone does not support Bluetooth 5.0, it can still be downward compatible, downgrading to 4.2 to use.

So no matter whether your phone supports it or not, Tony suggests that it is best to choose a headset that supports Bluetooth 5.0.

In addition, the “true wireless” described by the split Bluetooth headsets actually refers to Qualcomm’s TWS (True Wireless Stereo) true wireless stereo technology.

The traditional Bluetooth headset can only be connected to a single headset, and the left and right headsets can be connected through the line to synchronize the sound.

The TWS Bluetooth headset, in short, connects one of the headsets as the main headset to the mobile phone, and then connects the main headset to the remaining headset, thereby realizing the wireless separation of the left and right channels.

It is precisely because the split earphones are divided into main and auxiliary earphones, so after a long time, you will find that the battery consumption of the two earphones is different.

The TWS Plus technology developed on the basis of TWS uses both earphones as main earphones and connects directly to the mobile phone.

While avoiding the difference in battery consumption, latency and power consumption are also reduced.

At present, TWS headsets have achieved a hundred yuan level.

Most of the hundreds of expensive Bluetooth headsets use TWS Plus technology. If possible, choose TWS Plus Bluetooth headsets.
