BOSE is one of the largest speaker manufacturers in the United States and the largest home theater brand in Europe and the United States. It is the only commercial speaker designated on the U.S. Space Shuttle, and BOSE is also used at the Barcelona Opera House and the Sydney Olympic Games.
 
BOSE is one of the most important manufacturers of computer audio among the international brands, and the products are not simply reduced from the large audio, and all products have been redesigned and tuned for the computer. There are not many computer speaker products, the more popular ones areCompanion50, Companion2, Companion20 and Musicmonitor, the price is about 1000-4000 yuan, focusing on the high-end market. Except for the Companion2, which uses a plastic shell, the other three are made of aluminum alloy with a stylish design, and the four products are all at the middle and upper level in terms of appearance.
 
In terms of sound quality, the 4 products are very good, of which the Companion2 is priced at 950 yuan, but it is not very competitive in the same price range. The Companion20 and MusicMonitor are far superior to the Companion2 in terms of appearance and texture, among which MusicMonitor has passive dual-diaphragm technology, and the two conical magnet units equipped inside resonate with the sound generating unit, which improves the quality and quantity of low frequencies, and is more suitable for game and movie users. The Companion20 has an extended touch control wheel and supports audio input and output interfaces for ease of use.
 
The most recommended of the four products is the Companion50, which is priced at 3800 yuan, which is an upgrade to the classic model Companion5. The old Companion 5 has been included in the list of computer speakers recommended by well-known media such as Digital Trends and Heavy.com, the biggest feature of the speaker is the use of its own unique TrueSpace decoding technology, it is designed for computers, only two speakers can be used to restore the 5.1 surround sound effect, and its unique Acoustic Equalization sound equalization technology, It also keeps the sound quality of the speaker excellent at any volume.
 
Although the new Companion50 cancels the 5.1 channel effect on the Companion5, the sound quality still continues the characteristics of the old model, the sound field is wide, the sound is clear and the sense of power is strong, and the layers are clear, which can create a feeling of bullets when playing games, which is very shocking, but the bass is slightly inferior when listening to music. Overall, the Companion 50 is a set of computer speakers that are biased towards entertainment, which is more suitable for watching movies and playing games, and it is not large in size and takes up little desk space, making it one of the first choices for computer entertainment speakers.
