BOSE is the originator of active noise cancelling headphones, and the world's first active noise cancelling headphones were invented by its founder, Amar Bose, in the field of active noise cancellation, BOSE has been in a monopoly position for a long time. Many people have come into contact with the concept of active noise cancellation through BOSE, and it can be said that BOSE is synonymous with active noise cancelling headphones.
 
On the business side, BOSE is the standard noise-canceling headset for first class and business class of many large airlines. In the mass consumer market, SONY's noise-canceling headphones have not yet emerged, and only BOSE is the only top-of-the-line active noise-canceling headphones.
 
Unlike Sony, Sennheiser, AKG and other traditional headphone manufacturers, BOSE is the only brand that regards noise-canceling headphones as its own flagship, and the models launched are all high-quality products, and the well-known QC35II. and QC30 occupy the top five in the list of active noise-canceling headphones from major evaluation agencies all year round, among which QC35II ranks first in the United States "Consumer Reports", and has won unanimous praise in terms of sound quality and noise reduction effect.
 
At present, the models on sale are QC20, QC25, QC30, QC35II., QC35II. is an upgraded version of the QC35 generation, and the first three models were launched earlier. Although the initials on their model names are QC, and people are used to only calling them abbreviations, but in fact, there are many differences between the two, QC20 and QC30 are in-ear headphones, of which QC is QuietControl, which highlights the quick control, while QC25 and QC35II are head-mounted types, in which QC stands for QuietComfort, focusing on wearing comfort.
 
The biggest difference between the head-mounted QC25 and QC35II is that QC35II supports wireless Bluetooth connection, QC25 is a traditional wired connection, and QC25 supports battery replacement, appearance, button layout is not much different, noise reduction effect, wearing comfort is also very small, due to the loss of Bluetooth transmission, wired connection QC25 is slightly better than QC35II in sound quality, but it is only the level of ordinary non-noise canceling headphones at the level of 1,000 yuan.
 
Although there is not much difference between the two, wireless noise-canceling headphones have a higher degree of freedom and are suitable for more scenarios, which has become a big trend today, and QC35 is definitely a better choice. It is ideal for use on long-haul planes, trains and high-speed trains, and its excellent noise reduction effect greatly shields the engine noise of aircraft and the friction of rails. It is also suitable for daily commuting, well suppressing the wind noise and road noise of buses and subways, while suppressing noisy voices, it can also intelligently identify the alarm sound such as station reporting and honking, so as not to sit in the station and be dangerous, the price is 2900 yuan.
 
As for QC20 and QC30, the difference is that QC30 is a neckband design, while QC20 is a traditional wired design, and the prices of the two are 2000 yuan and 2500 yuan respectively. In terms of noise reduction effect, there is not much difference between the two, QC20 is slightly better, and both are at the middle and upper level of the industry. In terms of sound quality, there is still a big gap between the two and QC35, if you choose from the two, QC30 is more recommended, it gets rid of the shackles of cables, and users no longer need to endure the huge noise reduction module assembly, with unique shark fin silicone ear tips, the firmness and comfort after wearing are well-known, which is very suitable for daily commuting and sports.
 
Compared with Sonywi-1000X, which is also a neckband, QC30 is better in noise reduction effect, and the noise floor after turning on noise reduction is also smaller, but the sound quality is slightly worse, and the three frequencies are defeated, of which the gap between the mid-frequency vocal part is the largest. In fact, both are good enough, but the orientation is different, users who focus on noise cancellation and comfort can choose the QC30, while users who focus on sound quality choose the WI-1000X.
