With the popularization of mobile devices, we face screens longer and longer every day, but whether it ’s a mobile phone, tablet or laptop, the sound quality of the external speakers is poor, especially when using a mobile phone, it also consumes electricity, and Bluetooth speakers are small and portable, and wireless transmission can solve this problem very well. But how should we choose Bluetooth speakers?

Pick a Bluetooth speaker, we need to pay attention：

(1) The battery life of the speaker. The battery life of the speaker is the same as the mobile phone, of course, the longer the better. Normally, when other values are constant，the battery capacity is proportional to the use time. The larger the power capacity, the stronger the battery life.

(2) Bluetooth version. Try to choose a speaker with a higher Bluetooth version. The higher the Bluetooth version, the more power-saving the Bluetooth speaker, the longer the effective distance, and the stronger the Bluetooth compatibility. Earlier versions of Bluetooth may not guarantee good battery life and signal transmission.

（3）Sound quality. The best way is to listen to the sound of the speakers yourself. Objectively speaking, the sound quality of Bluetooth speakers cannot be competed with large speakers due to physical limitations. We need to pay attention to several points during the audition. First, whether the loudness of the speaker is loud enough; second, whether there is a cracking phenomenon in the treble at the maximum volume.The most commonly used in listening to popular music and watching movies is the middle and high-frequency part of the speaker. Pay attention to whether the sound resolution is high enough (clear and delicate).

(4) Portability and versatility, that is, how big the volume and weight of the speaker, if it is used outdoors. Waterproof and drop resistance is very important, due to inevitable that it will rain or fall when playing outdoors. The waterproof level depends on the IPX level of the product. The higher the level, the better the protection.
