Hi-Res, also known as High Resolution Audio, is not unfamiliar to headphone enthusiasts. The purpose of Hi-Res audio is to showcase the ultimate quality of music and the reproduction of the original sound, obtaining a realistic experience of the live performance atmosphere of the original singer or performer. When measuring the resolution of digital signal recorded images, the higher the resolution, the clearer the image. Similarly, digital audio also has its "resolution" because digital signals cannot record linear audio like analog signals, and can only make the audio curve closer to linearity. And Hi-Res is a threshold for quantifying the degree of linear restoration.
What is Hi-Res Audio:
Hi-Res Audio is the abbreviation for High Resolution Audio. It is a high-quality audio product design standard developed by JAS (Japan Audio Association) and CEA (Consumer Electronics Association). The Hi-Res Audio logo is currently only for use by JAS members. The use of this logo requires JAS permission and will be provided to CEA member companies through a licensing agreement with JAS for product promotion, advertising, and promotional activities.
The process by which brand merchants are authorized to use the Hi-Res Audio logo and Hi-Res Audio Wireless logo is referred to as Hi-Res certification in the industry. This means it's not just a simple certification mark. This is a music system that includes music resource monitoring devices from the association (including a series of products such as walkman, earphone earplugs, earbuds, speakers, etc.).
More and more products have obtained Hi-Res certification, and Hi-Res certification has become an essential certification mark for high-end audio devices. CEA and logo authorized users agree to comply with the HRA product guidelines and performance requirements stipulated by JAS. Hi-Res enables portable audio and video to have full range and high bitrate capabilities. The addition of the Hi-Res label to headphone products not only represents an ultra-high listening experience, but also represents the unanimous recognition of their headphone products in terms of quality and sound quality in the industry. It is one of the symbols of whether a headphone reaches high-end.
