1. Compatibility. Although the compatibility of Bluetooth speakers basically supports 100% of existing Bluetooth devices, it is still necessary to check whether your broadcast equipment supports Bluetooth before buying.
2. Sound quality. After all, buying a Bluetooth speaker just to listen to music has a better experience, so you must pay attention to its sound quality. The sound quality depends on the Bluetooth version, but nowadays most of the market choose Bluetooth 4.0, and the sound quality is still guaranteed.
3. Transmission interval. This problem is also our concern throughout. The transmission interval of the Bluetooth speaker has nothing to do with the Bluetooth version, and the first thing still depends on the advanced level of skills. So when choosing a Bluetooth speaker, you can choose a signal that is stable and has strong anti-interference.
4. The battery and the quality of the built-in battery of the Bluetooth speaker directly determine its broadcast time and service life. Before buying, please inquire about the practice broadcast time and the number of repeated charging decay. It is recommended that consumers choose lithium polymer batteries as much as possible when choosing Bluetooth speakers, without risk of explosion.
