Judging whether the sound quality of Wired Headphones meets the high-fidelity standard is an important issue for audio enthusiasts and professionals. The following aspects can help you make a judgment.
1. Frequency response
High-fidelity headphones should have a wide and flat frequency response range. Generally speaking, it is ideal to cover the frequency range of 20Hz to 20kHz. Within this range, the headphones can accurately reproduce various sounds, from low bass to crisp high notes. If the frequency response is unbalanced, it may cause the sound of certain frequencies to be over-emphasized or weakened, affecting the overall sound quality. You can understand its frequency response by checking the technical parameters of the headphones or professional audio test reports.
2. Resolution
High-fidelity headphones should have excellent resolution and be able to clearly distinguish various sound details. For example, when listening to music, you can hear the subtle changes in the timbre of instruments and the breathing of singers. Headphones with high resolution can make you feel more realistic and rich musical expression. You can judge the resolution of headphones by listening to some complex musical works, such as symphonies and jazz.
3. Distortion
Low distortion is one of the important features of high-fidelity headphones. Distortion refers to the degree of difference between the sound output by the headphones and the original sound. High-fidelity headphones should reduce distortion as much as possible to make the output sound closer to the original sound. Generally speaking, the lower the distortion, the better the sound quality. The distortion of the headphones can be measured by professional audio testing equipment, or by listening to some pure audio signals, such as sine waves, to judge the distortion of the headphones.
4. Dynamic range
High-fidelity headphones should have a large dynamic range and be able to reproduce huge changes from weak sounds to strong sounds. Headphones with a large dynamic range can make you feel more shocking and realistic music effects. You can judge the dynamic range of headphones by listening to some music works with strong dynamic changes, such as movie soundtracks, rock music, etc.
5. Tone
The tone of high-fidelity headphones should be natural, real, and not too colored. Different headphones may have different tone characteristics, but in general, they should be able to accurately reproduce the tone of various instruments and human voices. You can judge whether the sound quality of the headphones meets the high-fidelity standard by listening to some familiar music and comparing the differences in sound quality between different headphones.
In short, judging whether the sound quality of Wired Headphones meets the high-fidelity standard requires comprehensive consideration of multiple factors. By evaluating frequency response, resolution, distortion, dynamic range and timbre, the sound quality level of the headphones can be judged more accurately. At the same time, personal hearing experience is also very important. Different people may have different preferences for sound quality. Therefore, when choosing headphones, it is best to listen to them in person to find the most suitable high-fidelity headphones for yourself.
