[Technical Article] 6 questions about headphones

The gap between high-quality and low-quality headphones can be quite significant. High-end brand-name headphones and budget ones from small or counterfeit producers can vary greatly in sound quality. Poor headphones may produce sharp treble, harsh bass, distorted sound, or a noticeable change in vocal tone. Sometimes, the sound might just feel off, and it can be hard to pinpoint exactly what's wrong. In severe cases, the sound distortion could harm your hearing. For instance, listening to Jacky Cheung's songs might feel unnatural, though it's tough to describe precisely why. Lower-end headphones often lack the craftsmanship, materials, and tuning expertise that premium brands invest in, making the sound less detailed and more fatiguing over time. On the other hand, high-end headphones are built with superior craftsmanship, materials, and meticulous tuning. The sound produced feels rich and full, even at higher volumes, without causing discomfort. These headphones can reproduce sound with great accuracy, immersing you in the music. For example, listening to Faye Wong's tracks might feel like she's performing right in front of you. Naturally, the price reflects the quality and effort put into creating these headphones. People often ask which brand offers the best headphones. The truth is, every brand has its unique strengths and weaknesses. What works best for one person may not suit another. Many cities have high-end headphone experience stores where you can test different brands and models. The key is to find headphones that match your personal preferences and listening style. The sound produced by different headphones depends heavily on the tuning decisions made during design. This is akin to cooking—same ingredients can result in vastly different dishes depending on the chef's skills and preferences. A simple way to choose a brand is to consider whether the brand's sound style aligns with your tastes, as the tuning of headphones is influenced by the nationality of the designers. For instance, German headphones tend to be precise, while American ones might be more dynamic and expressive. Different headphones sound so distinct because the environment in which the music is played affects the final output. Imagine someone singing in an empty room versus a well-decorated one—the acoustics will differ significantly. The former might have more echoes, while the latter provides clearer sound. Ultimately, it's not the brand itself that determines whether headphones are good or bad, but whether they suit your needs. The best way to determine suitability is by visiting a physical store to listen. Wearing headphones that don't match your preferences can lead to frustration. Listening to music should be enjoyable and relaxing. Why does the sound quality of newly purchased expensive headphones seem underwhelming at first? Many people buy headphones worth tens or hundreds of thousands, only to be disappointed upon unboxing. The sound quality appears poor, leading to feelings of deception. However, all headphones require a "burn-in" period after initial use. During this time, the sound improves progressively, eventually reaching the desired quality level. This process is referred to as "breaking in," and it's especially noticeable with mid-to-high-end headphones. Inside headphones, there's a diaphragm that vibrates to produce sound. Mid-to-high-end headphones typically have thicker diaphragms, which take time to shed their stiffness and achieve optimal sound performance. Other components also require time to stabilize before delivering consistent sound quality. Therefore, when purchasing high-end headphones, it's advisable to connect them to an audio source for a while with moderate volume. Different headphones have varying burn-in times, and some high-end models require extended periods to deliver their full potential. This applies not only to headphones but also to computer speakers. Higher-end speakers improve significantly after adequate warm-up time. Regarding bass and sound quality, many believe that heavier bass equates to better sound quality. While this might appeal to some, it's a misconception. Heavy bass sacrifices sound details, distorting the overall sound and affecting clarity. This is particularly problematic for studio monitors designed for accurate sound reproduction. Losing sound details also impacts the "soundstage," which refers to the perceived space of the sound. A good soundstage allows listeners to visualize the location of sound sources. Heavy bass compromises this, making the scene feel flat and less immersive. Heavy bass tuning can also distort vocal performances, making singers sound overly deep. High-fidelity headphones, however, allow listeners to feel like the singer is right in front of them. The downside of excessive bass is potential hearing damage. Powerful bass from computer speakers or headphones, especially over prolonged use, can lead to conditions like tinnitus or temporary hearing loss. For those who enjoy bass-heavy sound, adjusting the volume can help mitigate risks. Is it worth investing in a good pair of headphones? Many premium headphones offer exceptional sound quality, but achieving this requires specialized knowledge in sound engineering. Most smartphone manufacturers lack this expertise and rely on third-party suppliers for audio components. Despite this, many modern phones boast HIFI-grade audio chips capable of playing high-resolution audio files. Pairing these phones with quality headphones can unlock incredible sound experiences. Original smartphone earbuds, however, fail to utilize the phone's full potential. Today, many high-end headphone brands offer models with integrated microphones, combining superior sound quality with call functionality. These are excellent upgrades for standard smartphone earbuds. With the rise of mobile entertainment, HIFI headphones provide an immersive experience for movies and shows. Dialogue and ambient sounds become more realistic and engaging. What defines a good pair of headphones? Unlike speakers, headphones sit directly on your ears, amplifying even minor sound quality differences. Balanced sound quality ensures that complex music remains soothing and not jarring. One way to judge is by wearing headphones and listening to songs that leave you feeling relaxed and comfortable. Such headphones enhance your mood and create a sense of tranquility. In today's fast-paced world, music serves as a form of relaxation. Poorly tuned headphones can have the opposite effect, making listening stressful over time. Secondly, good headphones must have sufficient fidelity, accurately reproducing the original recording. Ideally, they should convey the subtleties of the singer's emotions, allowing listeners to feel the singer's mood while enjoying the music. Additionally, headphones should have a good balance of high and low frequencies. Excessive bass diminishes details, while harsh treble can be uncomfortable. Premium headphones deliver smooth, natural highs and lows. The most challenging aspect of headphone tuning is creating a convincing soundstage. This involves recreating the recording environment, enabling listeners to visualize the positions of instruments and singers. Top-tier headphones can transport listeners to the heart of a concert hall, where each instrument plays with precision. At its highest level, sound tuning becomes an art form. Different styles, cultures, and designers shape distinct sound signatures. Inferior headphones provoke anxiety, while excellent ones bring comfort, joy, and an appreciation for the artistic nature of music.
