Planar Magnetic Bluetooth Headphones
These headphones provide a truly immersive listening experience. They have an elegant, luxurious design and a sound quality that is impressively precise. They're specifically designed for audiophiles who require high quality music.
RHA has developed a revolutionary technology to reduce distortion to less than 0.5 percent. The CL2 is equipped with a ten millimeter planar magnet driver, suspended over two arrays of magnetics.
Accuracy
Planar magnetic headphones use ultra-thin diaphragms between two magnets in contrast to traditional headphones that utilize cones and moving coils to move air. This allows them better precision and crystal clarity. However, they are more bulky, difficult to power, and more expensive than their dynamic counterparts, which is why they're not yet dominating the market.
Thankfully, audio brands that are boutique such as Audeze and HIFIMAN are constantly improving and creating new models that make the best of this new technology. The most recent version of the Audeze LCD-5 headphones for instance is less bassy and more balanced than its predecessors, all the while still retaining the high clarity and resolution. The soundstage has also been enlarged and revealed which allows you to hear sounds that were not there before and to enjoy classics with a new perspective.
A wider soundstage also gives an enhanced sense of depth and place. The spherical driver of many modern closed-back magnetic headphones such as the Oppo PM-3 can also make them sound a bit too wide at times, especially when sounds pan from left to right. The more symmetrical design of HIFIMAN Ananda, on the other hand, is designed to deliver an even more natural and precise stereo sound than the majority of competitors' headphones.
While the advantages of having the larger soundstage are evident, most users will find that they prefer more balanced and neutral tuning for their headphones. This is the reason that most magnetic headphones made for planar use come with both open-back and closed-back models, with the former offering the more traditional and practical design that can be used on a regular basis.
The following are some of the most effective ways to boost your effectiveness:
The planar magnetic driver inside RHA's CL2 headphones produces an audio that is extremely precise. Their compact ten-millimeter driver houses a 16-micrometer diaphragm perfectly suspended over two magnetic fields for superior reproduction up to 45,000 Hz.
The diaphragm has a more homogeneous molecular structure than traditional cone drivers, which means there's less distortion across the frequency range. planar magnetic vs dynamic makes the sound have a much more natural dynamic response, giving it a lush and detailed image quality.
To further reduce distortion, the diaphragm has been encased in a precision-machined aluminum housing. The result is a light and durable design with a smooth inner surface that allows for a continuous flow of audio waves between the microphone and the speakers.
These features create a headphone that sounds great regardless of the volume you are playing it at. The soundstage is huge and covers your entire headspace with distinct sound separation that gives your music a sense of depth.
The Glasgow-based company uses superior materials to make the CL2 headphones. They use zirconium dioxide, an indestructible material that's used to create synthetic diamonds and protect jet engines. The resulting ultra-thin, black stainless steel housings are durable and scratch resistant with distinctive matte finish made using superheated plasma and powdered dye.
The CL2s are compact magnetic headphones that provide wireless listening via their Bluemini adapter, which supports Bluetooth 4.1 for aptX and AAC streams. They also have detachable 3.5mm and balanced 2.5mm cables with oxygen-free copper cores that ensure that analogue signals are delivered to the headphones without distortion.
Soundstage
A vast and expansive soundstage is among the most sought-after features among audiophiles. In contrast to those who enjoy listening to Taylor Swift over laptop speakers audiophiles require a wide and precise soundstage that lets them completely immerse themselves in the music.
The soundstage's quality is greatly dependent on the headphones and their acoustics. To maximize the benefits of the soundstage of a headphone, it is important to know how headphones are made and designed. The design of the headband, earpads and microphones all play a part in creating the soundstage.
For instance, the size of a headband plays an important part in how open and spacious the soundstage appears. A bigger headband means an expanded soundstage and less distortion. The quality of the earpads also is a factor. The earpads need to be comfortable and have an adequate seal to minimize resonance and unwanted noise.
Another benefit of a headphones soundstage is the clarity of every instrument. A clear soundstage makes easy to differentiate between different instruments and vocals in a song even at higher volume. The clarity of the bass also plays a significant role in the overall sound quality of headphones.
In turn, the bass response of headphones with planar magnetics tends to be better than that of dynamic drivers. The headphones with planar magnetics have larger magnets which move the entire diaphragm. Dynamic drivers have a smaller dialum that is vibrating in response to electrical impulses generated by the voice coil. This creates an unidirectional sound wavefront, rather than the focused spherical one found in dynamic drivers, which helps to locate sound more precisely when it enters the ear.
Furthermore flat sound waves requires more power than a spherical which results in planar headphones with larger magnets and needing stronger amplifiers. This is why planar headphones are typically a bit heavier and bigger than dynamic headphones.
Distortion
The distortion of your headphones is due to the voice coil moving back and forth rapidly, compressing and decompressing air around a diaphragm for the speaker. This causes the various points on the diaphragm to move out of alignment, which sounds fuzzy and distorting. Planar magnetic headphones have lower distortion rates because the drivers apply uniform driving forces to the entire flat surface. This produces low distortion even at high volumes.
Planar headphones are also renowned for their wide frequency response. They can reproduce a broad spectrum of frequencies, from low bass to high treble. Additionally, they are able to provide a fast transient response, which means they can respond quickly to changes in the audio signal.
Planar headphones are an excellent choice however, they aren't always easy to drive using an external amplifier. They require more power and have larger magnet arrays. Fortunately, there are some high-quality planar headphones that can run directly from mobile devices as well as desktop audio players.
The CL2 Planar from RHA makes use of an oxygen-free copper core as well as customized neodymium magnets to provide high efficiency. They are compatible with all Bluetooth devices and can be used wirelessly or with wired connections. The cables are available in 3.5mm and balanced 2.5mm and premium materials. They are also braided for durability and strength.
If you're in the market for a pair of Bluetooth planar headphones or just a good set to listen to music, there are plenty of good options to choose from. But, it's essential to consider your listening preferences and budget before making the purchase. While it's tempting to buy the most expensive headphones, you might discover that they don't sound as good as a cheaper pair.
Leakage
As the name implies the headphones are planar. They use a flat membrane that is surrounded by magnetic fields to create sound. They also have a much thinner diaphragm which is often 80% smaller than a dynamic driver. Because of this, they can deliver more detail and a richer sound than their larger counterparts. The downside is that they also require more power to work. While some headphones with a planar design, such as the HIFIMAN DEVA can be powered by phones, the majority need a dedicated headphone amp to ensure the best sound.
Due to their bi-directional motion that they have, planar magnetic headphones tend to let out more sound than headphones with traditional voicecoil transducers. They are therefore not suitable for use in public, particularly in situations where you don't wish to cause disturbance to other people. However, this can be avoided by choosing closed-back headphones with a tight seal to prevent the sound from escaping.
