With the continuous development of life, we have higher and higher requirements for the quality of music. From the Walkman, MP3, MP4 to the current speakers, we can see our love for music. A high-quality speaker can increase the fun of life and give people happiness. The first thing I think of is the Bluetooth speaker. Nowadays, the Bluetooth speaker has become a necessity of many users. Compared with the traditional desktop speakers, Bluetooth speakers are small in size, not only easy to listen to and carry, but also have various functions. In addition, the sound quality of Bluetooth speaker is getting better and better. In terms of sound, it can meet the requirements of most users.


I. whether it is light and portable
A large part of the reason why we bought the speakers is to make it convenient for us to go out and use them: we go outing with our family on weekends, open the speakers on the grass and play a soothing music; the elders at home can take the speakers to the square park for entertainment after supper, etc.; so if we have a small portable speaker, it is simply too convenient for us. For example, the size of this BIU speaker is only 78mm, and its thickness is only 33mm. It's not as big as the palm of your hand. One speaker is only 124g, so it can be said that it's under control.


Two, brand
Now there are a lot of rough Bluetooth speakers in the city, which not only fail in quality inspection, but also cause harm to people's health. For example, many paint materials contain lead, which will affect people's health unconsciously. Therefore, the quality inspection certificate should be clearly seen when purchasing. The fineness of a speaker can be seen from the manufacturer's attitude towards the production of the product, as well as the sense of responsibility to consumers. Most of the multimedia speakers we have seen before are wooden boxes, while the Bluetooth speakers are different. Most of the Bluetooth speakers are made of plastic, metal and other materials. The purpose of doing this is to be more light. Generally, we are familiar with the regular brands like Suning, which are not careless in the materials used for the speakers. Even if the plastic materials are used, there are few such phenomena as uneven surface, thin texture and so on. Some attentive brands even cover the exterior of the speaker with waterproof coating or special waterproof paint to meet the needs of users for outdoor travel. When buying speakers, we must pay attention to whether the interface is flat, and weigh the speakers by hand. Although the speaker with too light weight is portable, it is easy to damage the internal parts due to slight collision.


III. whether to wait for power supply and have strong endurance
Compared with the old-fashioned speaker at home, waiting for electricity is one of the characteristics of this portable speaker; therefore, to choose a good portable speaker, first of all, we need to see its waiting capacity, waiting time, and its battery size.


IV. sound quality
I don't know if you've ever felt like this: when you open the speaker cheerfully to appreciate the music, at first you think it's not bad, the sound is loud enough, clear enough, and the bass is smooth. But it's not so "comfortable" after listening for a while. It's special "Feier". This kind of speaker, which feels very tired, can't be liked by everyone because it is "noisy". The "noisy" sound box means that the sound quality of this speaker is not good, it can't bear listening, and it loses the original feeling of music.


V. whether Bluetooth is supported
The convenience brought by Bluetooth is obvious to all. An important part of the product's Bluetooth function depends on the Bluetooth chip. For example, the small BIU speaker is equipped with a Bluetooth 5.0 chip. This product has a strong compatibility, and after the connection with other mobile devices, its stability performance is also the most powerful, the transmission ability is particularly fast and accurate.


Of course, many Bluetooth speakers on the market use low-cost Bluetooth modules. This kind of products not only have a large amount of heat, but also show instability when connecting with other devices. This is also why we are easily disturbed or disconnected when using a part of Bluetooth speakers.
