EarPods are said to have taken hundreds of people's eardrums to study the shape, and AirPods are estimated to have made a lot of little-known efforts in this regard, which is Apple's strength.

As long as you open the lid of the storage box and get close to the iPhone, it will automatically connect and pair, all in one step, which is the fastest Bluetooth pairing in history. Although the continuous use of AirPods is only 5 hours, but because you will certainly carry the storage case with you, so put back to charge on the line, the official saying is 15 minutes to use 3 hours. AirPods sound effect don't expect too much, basically maintain the EarPods always boiled water style, use it to listen to any music will not be too effective, the only outstanding thing is that the mid-frequency voice is relatively clear, but the performance of the bass is like dragonfly water has no taste, but you don't blame Apple, in the iPod era they do not have the so-called \"sound dye\
5 to 6 years, there is still 50% capacity. Not less than 80% capacity in 2 years. Battery life means that the capacity does not reach the nominal, the internal resistance exceeds, the performance deteriorates, not completely unavailable. Lithium batteries, if overdischarged, can not be recovered and completely broken; Therefore, when storing, it is also necessary to charge once every six months to keep the battery from self-discharging and causing over-discharge.
