Share: How to choose Bluetooth audio?
The popularity of smartphones and tablets has spawned a range of peripheral peripherals, of which portable Bluetooth speakers are more common. Because of its small size, exquisite appearance, coupled with the wide compatibility of Bluetooth chips and carrying many novel features, it is loved by young people. The portable Bluetooth speaker market is a relatively new field, and there are also many phenomena in which the fish are mixed. Take Yixun as an example, there are 48 portable Bluetooth brands, and the number of products is 377. These data do not yet include unidentified cottage brands and products. What is the current status of Bluetooth speakers? How to buy Bluetooth speakers correctly? I hope this article can give you some inspiration.
Bluetooth speaker market status:
At present, the mainstream Bluetooth small speakers on the market are composed of several parts: domestic brands, international brands and the so-called cottage brands. The existence of different types of products also meets the needs of the mainstream market. There are many domestic brands and the price is in the middle. Most buyers will purchase these products that are both reassuring and affordable. The price of international brands is basically 3-5 times that of domestic brands. Even higher, the users of the purchase are concentrated in the digital masters and geeks; more cottage products are spread all over the stalls, subway stations and other corners, the price is very low, the sound quality slag can be imagined, and the purchase They are more of a user who is not sensitive to digital products. At present, the Bluetooth speaker market is chaotic, and there are still many problems.
Awkward face, homogenization is still serious
Almost 100% pure imitation
Homogenization is an inevitable topic, and the homogenization of the audio circle has its own characteristics. It is said that the foreign moon is more than a circle of its own, Bluetooth speaker and foreign famous brand speakers "accidental" face is not a case. Imitation is a shortcut to quickly become famous. After all, it is standing on the shoulders of giants, stealing the concept, and plagiarizing the appearance is almost no high cost. On the other hand, homogenization is reflected in the technical level. Technology Kaiyuan is the current status quo. The entry point of various technologies is not high. Manufacturers can do it as a trick! You have Bluetooth at home, and I have low cost of NFC. Also add, just like the smart phone on the market, just a function, which can be achieved on the phone. This greatly increases the consumer's identification cost.
The chaos in the industry, how to fight with the cottage? !
Some users are sensible to be fake, and are willing to pay for their pockets, because the two words: cheap!
Due to the high threshold of audio high-end, ordinary manufacturers are not easy to enter due to technical and financial constraints, so this field is relatively stable, there will not be many new competitors; and the market for Bluetooth speakers is different. Strolling through the subway station in Guangzhou, the village in the city, and selling along the street stalls are mobile power, Bluetooth speakers and cheap headphones, of which Bluetooth speakers can start with a minimum of thirty or fifty dollars, many products are also under the banner of foreign big brands, arrogant This will bring a small impact to the formal manufacturers to a certain extent. There are many brands of portable speakers, although some manufacturers are also a formal brand that has begun to take shape. However, because the industry is too new and the audience's awareness is low, it is very likely that they will be mistaken into the ranks of the cottage. How to accurately identify genuine and cottage, how to choose the product that suits you according to your own consumption ability, we will specifically talk about it below.
How to choose a Bluetooth speaker
People buy things and look for objects, people tend to believe in their eyes. At first glance, it seems that the call is successful, which means that the transaction is successful for more than half, so the choice of Bluetooth speaker shape is the most valued by consumers, and the most benevolent. Everyone's aesthetic taste is different, so the choice of appearance on the small series will not cost more. From other perspectives, we should pay attention to what to buy Bluetooth speakers.
1, Bluetooth version:
Bluetooth version improvement technology
Although the latest Bluetooth version is backward compatible, no matter which version of Bluetooth is almost 100% compatible, it does not mean that the Bluetooth version is not important. Up to now, there are six versions of Bluetooth technology, including V1.1, 1.2, 2.0, 2.1, 3.0, and 4.0. The high version is backward compatible. V1.1 and 1.2 have been basically eliminated. The most widely used ones are currently. V2.0, 2.1 version, its transmission rate can reach more than 2Mbps, and can transmit data and voice at the same time. The latest improved versions V3.0 and 4.0 have been released, and the transmission speed has been greatly increased to 24 Mbps, and the theoretical value of the transmission distance is up to 60 meters. Therefore, before buying, you need to understand the Bluetooth version of your playback device. Xiaobian recommends that you purchase a newer Bluetooth speaker with a version of 2.1 or higher. If the Bluetooth version is too low, it is easy to play music intermittently.
2, about the material:
Observe the workmanship at the details
Unlike traditional multimedia speakers, which use wooden cabinets, most Bluetooth speakers are usually made of plastic or metal. Usually the regular brand does not save money on the materials used in the speakers. Even if it is made of plastic material, there will be little surface unevenness and thin texture. Some thoughtful brands even put a waterproof coating on the outside of the speaker, or a special waterproof paint to meet the needs of users traveling outdoors. Here Xiaobian should remind you to pay attention to whether the interface of the speaker is flat when purchasing, and manually measure the weight of the speaker. Speakers that are too light in weight are portable, but slight bumps can easily cause damage to internal parts.
3, battery life:
Mainstream dual unit portable Bluetooth speaker parameters list
The battery life of the speaker is the same as that of the mobile phone. Of course, the longer the better. Of course, everything has a peak, Xiao Bian suggested that under normal use, the ideal battery life of Bluetooth is maintained at 8-10 hours. Listen to 3 hours a day for 3 days. Usually the working time of the speaker has a certain relationship with the battery capacity and the power of the product. Battery capacity = use time × device power ÷ battery voltage. Simply put, when other values ​​are fixed, the battery capacity is proportional to the time of use. Taking dual-cell Bluetooth speakers as an example, their power is concentrated between 4W and 6W. If you want to achieve better playback time, the battery capacity should be above 1000mAh.
4, sound quality
The sound quality should be heard by yourself, choose the speaker that suits your hearing habits.
Objectively speaking, the sound quality of the small speaker is very awkward. It does not have the large size of the speaker and power like the hifi/target=_blank>HIFI speaker. Its sound quality is physically limited and cannot compete with the big speaker. But for the vast majority of users who are not golden ears, small speakers with a tablet and mobile phone are enough to meet the needs of hearing. In this case, how to judge the sound quality is good or bad? The most intuitive way is to listen to it personally. For example, BOSE and other brands have online stores with their own products for users to listen to. When you listen, you need to pay attention to a few points. First, the volume loudness of the speaker is big enough. Secondly, whether the high-pitched sound is broken at the maximum volume; the most commonly used part of listening to pop music and watching movies is the mid-range part of the speaker. Pay attention to the sound. Whether it is distorted, whether the sound is excessively dyed; the last low frequency, don't be too harsh, and reach your basic expectations.
5, other
Many small speakers are promoted with new, strange and special functions, such as self-contained alarm clock, wireless card reader, NFC, self-contained lanterns, etc. Although the function is very cool and convenient, it is not necessary to put the cart before the horse. Users should not cover up the original intention of purchasing Bluetooth speakers because of the gorgeous publicity.
to sum up:
According to the above suggestions to buy Bluetooth speakers, the general direction is basically correct, the rest is that users choose their own speaker products according to their own budget and taste. In short, choose a familiar brand, do not rush to buy a lot of unknown copper and iron, so as to avoid unnecessary security risks.
