Talking about the selection guide of Bluetooth noise-cancelling headphones
As a popular product in the recent headphone market, Bluetooth noise-cancelling headphones not only have a wide audience, but also have a wide variety of categories.
However, as a consumer, what should you pay attention to when purchasing a Bluetooth headset noise reduction product that suits you? We'll talk a little bit about it in the next article.
1. Noise reduction technology and application scenarios of Bluetooth noise reduction headphones
At present, the noise reduction technology adopted by mainstream Bluetooth noise reduction headphones on the market mainly focuses on three aspects: passive noise reduction, call noise reduction and active noise reduction. When buying a good noise-cancelling headset, you usually need to consider whether the noise-cancelling technology used is suitable for your own use scene.
From the perspective of usage scenarios, it mainly corresponds to complex and irregular noise environments, and users who pay attention to sound quality are more suitable for passive noise-cancelling headphones. Because passive noise reduction mainly relies on sound insulation materials, it can achieve lossless sound quality under the premise of full-frequency noise reduction (20-20Khz). .
Mainly for commuting, specific scenarios (airplane, subway), and users with certain call needs are more suitable for headphones that combine three noise reduction technologies. In such scenarios, the noise frequencies are mainly concentrated in the middle and low frequency bands, and the use of active noise reduction technology is relatively more targeted for sound processing in this frequency band; at the same time, the combined applications of call noise reduction and passive noise reduction in such scenarios include: Helps provide a better calling experience.
