How to choose the most suitable Bluetooth speaker?

1. The biggest buying point of Bluetooth speakers is Bluetooth wireless music playback. The Bluetooth version is related to the quality of the Bluetooth speakers. The higher the Bluetooth version, the more power-saving Bluetooth speakers, the longer the effective distance, and the stronger the Bluetooth compatibility. At present, the version of Bluetooth speakers is 2.0, 2.1, 3.0 from the earliest 1.1 to later; I heard that 4.0 is coming out soon, wait and see.
2. Speaker power: This involves the power of the speaker amplifier and the power of the speaker. Under the same conditions, the higher the power, the better the sound; of course, it also depends on the capacity of the speaker, such as some small speakers. If its power is too high, the speaker will be "not honest" when playing music, and it likes to jump, which is what people often say that the speaker can dance, so many manufacturers stick a layer of silicone pad or other things under the small speaker to make it. Does not bounce, but also increases the appearance of the speaker.
3. Speaker: When it comes to speakers, it's more complicated, internal magnetic speakers or external magnetic speakers, paper cones or other, speaker structure, speaker power, impedance, etc. It is generally difficult for non-professionals to know, and there is no such requirement for speaker sound quality. Gao generally doesn't pay attention to these.
4. Listen: listen to the sound quality of the speakers, whether there is noise, whether it is easy to break the sound, whether it is distorted, whether the sound sounds uncomfortable (the speakers with poor sound quality will feel very noisy after listening for a long time), bass and Is the high pitch reflected, etc.? Try to use different songs as much as possible during audiovisual, and the downloaded songs are best to use genuine ones. Many music files on the Internet have been processed, which is very different from the genuine music, and don't increase the volume too much during the audition. (This applies to any speaker)
5. Speaker cabinet material: In the past, we paid more attention to this. Everyone thought that the wooden cabinet was better than any metal or plastic. Of course, this is also true. However, with the research of the speaker cabinet, the metal, plastic and other materials are now The body can also achieve the same effect as the wooden box. Unless it is very professional and requires very high sound quality, the wooden box must be used.
6. Craftsmanship: With the development of the times, the craftsmanship of speakers has attracted more and more attention. Your speakers have no advantage in sound quality, but if the craftsmanship is well done and beautifully done, it can also be favored by the masses.
