There is a big difference between Bluetooth earphones and traditional wired earphones. Compared with wired earphones, Bluetooth earphones have higher requirements for technology and quality. Therefore, in terms of product quality issues, Bluetooth headphones, like general electronic products, their own service life has been the most concerned issue of consumers. In order to solve consumers' concerns about product life, almost all Bluetooth headset manufacturers have launched a "one-year warranty, free replacement" after-sales commitment.

Although the promise of free replacement of quality problems within a year makes most people feel free to pay the money, but with the gradual consumption of the life of the earphones in the process of use, some earphones began to break out in about two years. This phenomenon has to make people question whether the life of Bluetooth headphones is only one year, so the headset manufacturers are basically only guaranteed for one year.

In this connection, through detailed data analysis, we learned an industry truth: that is, the average life of Bluetooth headphones is really only 2 to 3 years (including thousands of Bluetooth headphones like Apple airpods). This is why most headphone manufacturers only dare to guarantee a free replacement within one year, and rarely dare to promise three years, because the promise of a long time will inevitably lose money. Therefore, it can be concluded that the headset is a relatively fast consumption of electronic products.

The life performance of Bluetooth headphones is mainly in the battery life of the headset. With the passage of time, the headset battery is gradually consumed, and the battery life of the headset also decreases until it is completely unusable. In other words, the natural life of a pair of Bluetooth headphones is directly determined by the battery life used by Bluetooth headphones.

At present, the batteries used by Bluetooth headphones are basically lithium batteries, because the energy density of lithium batteries is the largest battery in use at present, which can well meet the small design needs of Bluetooth headphones. Generally, the life of the lithium battery is after 500 cycles of charging, and the battery life of the Bluetooth headset can be calculated in this way. Therefore, in order to have a long service life of Bluetooth headphones, one side is to use a large-capacity lithium battery, and the other side is to reduce the power consumption of Bluetooth headphones, so as to increase the use time of 500 charges.

Understand the truth about the life of Bluetooth headphones, so how to choose a headset with a long life? Still need to start from the battery capacity and headset power consumption two aspects. For battery capacity, we can basically make a comparison from product parameters. However, in terms of power consumption, the determining factors are more complex.

If you want to reduce the power consumption of Bluetooth headphones, you should try to save power. Power saving can be started in the exterior design, reducing the flicker of the breath lamp, or it can be started in the core, using a low-power Bluetooth chip, or a low-power sound unit. As far as we know, the Bluetooth 5.0 chip is the lowest power consumption and the latest chip, and the power consumption of the sound unit of the moving iron is lower than that of the moving coil. I believe that according to the above introduction, everyone will probably know how to choose Bluetooth headphones according to the price, use scenario, and personal preferences.

Finally, there is a minefield that needs to be told in advance to avoid everyone stepping on the thunder. When comparing the battery capacity, we must not forget to look at the user feedback on the wearing experience of this headset, because some headphones will blindly use a large-capacity battery when pursuing high battery life, ignoring the stability and comfort of the headset itself when wearing. I believe that we do not like the kind of headphones that hurt ears for less than two minutes, in fact, friends with high comfort requirements can give priority to professional sports headphones.
