Planar magnetic headphones, also known as orthodynamic headphones, are a type of high-end audio equipment that uses a unique driver technology to deliver high-quality sound. These headphones utilize planar magnetic drivers, which differ from the dynamic drivers commonly found in most headphones. Planar magnetic headphones are known for their exceptional audio accuracy, clarity, and detail, making them a popular choice among audiophiles and professionals.
Here’s how planar magnetic headphones work and what sets them apart:
1. Driver Technology: Planar magnetic headphones use a different type of driver technology compared to traditional dynamic drivers. In dynamic drivers, a diaphragm is attached to a coil of wire that moves within a magnetic field, generating sound. In planar magnetic drivers, the diaphragm is a thin, flat sheet with conductive traces that are placed within a magnetic array.
2. Planar Magnetic Principle: The diaphragm in planar magnetic headphones is suspended between two sets of magnets, with the conductive traces aligned in a grid-like pattern. When an electrical current passes through the traces, it interacts with the magnetic field created by the magnets. This interaction causes the diaphragm to move and produce sound.
3. Advantages of Planar Magnetic Headphones:
- Detailed Sound: Planar magnetic headphones are known for their ability to reproduce audio with exceptional detail and accuracy. They can reveal nuances in music that might not be as noticeable with other types of headphones.
- Low Distortion: The design of planar magnetic drivers can result in lower levels of distortion compared to some other driver types, leading to cleaner audio reproduction.
- Wide Frequency Response: Planar magnetic headphones can often deliver a wide frequency response range, allowing you to hear both deep bass and high treble frequencies more accurately.
- Fast Transient Response: These headphones can respond quickly to changes in audio signals, resulting in better handling of fast-paced music or dynamic soundtracks.
- Size and Weight: Planar magnetic headphones can be larger and heavier compared to dynamic driver headphones, which might affect comfort during long listening sessions.
- Power Requirements: Planar magnetic drivers often require more power to achieve optimal sound quality. As a result, they might benefit from using a dedicated headphone amplifier.
5. Audiophile and Professional Use: Planar magnetic headphones are highly regarded in audiophile and professional audio communities due to their ability to deliver high-fidelity sound. They are commonly used by musicians, audio engineers, and serious music enthusiasts who value accurate sound reproduction.
It’s important to note that while planar magnetic headphones offer excellent audio quality, they might also come at a higher price point compared to headphones with other driver types. As with any audio equipment, personal preferences and the types of music you enjoy will influence whether planar magnetic headphones are the right choice for you.
