5 minutes to fully understand the headset, can't just listen to it!
In a world filled with busy car dragons, city chaos, and people who often feel isolated, late-night moments become a sanctuary for many. After work, the desire to find a cozy late-night canteen serving small dishes is common. But beyond that, there's also the longing for good music to accompany you on your way home. Headphones serve as a personal sound portal, allowing you to escape into your own world in any environment. But how much do you really know about headphones?
**—— Types of Headphones ——**
Headphones can be broadly divided into two main categories: over-ear and in-ear. Over-ear models are generally larger and heavier, making them less portable, but they offer superior sound isolation and powerful audio performance. In contrast, in-ear earbuds are compact and convenient, ideal for mobile listening on devices like phones, MP3 players, or CDs.
Based on the transduction principle, headphones can also be classified into dynamic and electrostatic types. Dynamic headphones are the most common, using a coil and diaphragm system similar to traditional speakers. They are efficient and widely used for general audio output. Electrostatic headphones, on the other hand, use a thin diaphragm in an electric field, offering fast response and minimal distortion, though they tend to be more expensive due to their complex construction.
There's also the dual-frequency headphone, which combines the best of both worlds by integrating elements from dynamic, electrostatic, closed, and open designs. These headphones excel in dynamic range, transient response, and sound clarity, making them a favorite among audiophiles.
Headphones also vary in openness: open, semi-open, and closed. Open headphones allow sound to pass through, creating a natural listening experience, while closed ones provide better noise isolation and bass response. Semi-open models aim to balance the advantages of both, offering comfort and sound quality.
**—— Key Headphone Parameters and Sound Quality Terms ——**
Understanding headphone specifications is crucial when choosing the right pair. Impedance refers to the resistance a headphone offers to electrical current, affecting how easily it can be driven. Sensitivity measures how loud a headphone can get with a given amount of power, with higher sensitivity meaning easier driving.
Frequency response describes the range of sounds a headphone can reproduce, typically covering 20Hz to 20kHz, matching human hearing. Other important terms include:
- **Sound Field**: The spatial representation of sound.
- **Tone**: The characteristic quality of a sound.
- **Sound Dye**: When a headphone adds coloration to the original sound.
- **Distortion**: Any deviation from the original signal.
- **Dynamic Range**: The difference between the loudest and softest sounds.
- **Transient Response**: How well a headphone reacts to sudden changes in sound.
- **Signal-to-Noise Ratio**: The ratio of useful signal to background noise.
- **Air Sense**: A term describing the presence of high frequencies and spatial separation.
- **Low Frequency Extension**: How low a headphone can go in terms of bass.
- **Bright/Soft Tone**: Describes the emphasis on high or warm frequencies.
- **Sound Quality**: A general evaluation of how good a headphone sounds.
**—— Amplifiers ——**
Amplifiers play a key role in enhancing sound quality. Power amplifiers boost the signal to drive speakers, while preamplifiers handle signal selection and volume control. Amplifier classes like Class A, Class B, and Class AB refer to different working states that affect sound accuracy and efficiency.
**—— Headphone Cables ——**
Most headphone cables are made from copper, with varying levels of purity. Higher purity copper reduces signal distortion, improving sound quality. Common types include TPC, OFC, LC-OFC, and OCC, each offering different levels of conductivity and sound clarity.
**—— Front-End Equipment ——**
For audiophiles, separating the turntable from the decoder can enhance sound quality. Front-end equipment includes CD players, turntables, and DACs (Digital-to-Analog Converters), all essential for high-fidelity listening.
**—— Breaking-in Headphones ——**
New headphones may not perform at their best initially. The diaphragm rings are rigid and need time to break in. As they soften, the bass improves, and overall sound quality gradually enhances. Proper break-in ensures optimal performance from your new headphones.
