For consumers, in order to prevent being cheated, they still have to improve their own product identification, as long as they have enough discrimination, they can not be fooled in front of a series of new terms and gorgeous propaganda.
Today we will take the Bluetooth headset selection as an example to show you what details we often overlook in the selection process.

Bluetooth transmission protocol:
Since the mobile phone canceled the 3.5 interface, Bluetooth headsets have become more and more popular among consumers.

Endurance:
Lifetime is also a concern for consumers when purchasing Bluetooth headsets. There are many Bluetooth headsets claiming how much life can be achieved, but there are few intentionally indicating under which circumstances this battery life can be achieved.
At present, the nominal battery life of the current Bluetooth headset is basically calculated according to the playback time under the SBC protocol. The higher the transmission quality, the more power is consumed. Therefore, if you use the LDAC Bluetooth transmission protocol, you will find The battery life of the headset has become significantly shorter.
Noise reduction:
For many consumers, the distinction between various noise reductions is not very clear. There are two types of noise reduction mentioned in Bluetooth headsets, namely active noise reduction and call noise reduction.
When many consumers choose the earphone, they will think that the earphone has active noise reduction when they see the noise-reducing function. In fact, it is only equipped with noise-reducing function. For this, consumers must look carefully.
In short, how to choose a suitable headset, in addition to the basic parameters, appearance, the above details still need to pay attention. Be sure to pay more attention to your purchases before you can buy your favorite products.
