Planar Magnetic Bluetooth Headphones

These headphones provide a truly immersive listening experience. They feature an elegant, luxurious design and a sound reproduction that is impressively precise. They're designed for audiophiles that require the highest quality music.

RHA has created a revolutionary technology that reduces distortion to an imperceptible 0.5%. The CL2 is equipped with a ten millimeter planar magnet driver suspended above two arrays of magnetics.

Accuracy

Unlike traditional headphones that use cones and moving voice coils to move air back and forth, these headphones have ultra-thin diaphragms set up between two magnets. This allows them to control sound waves in a more uniform fashion that provides greater precision and crystal clarity. However, they are heavier, more difficult to power, and more expensive than their dynamic counterparts, which is the reason they haven't taken over the market.

Boutique audio brands like Audeze and HIFIMAN continuously improve and launch new models to make the most of this amazing technology. Audeze LCD-5 headphones are a good example. The most recent model is less brash and more balanced, yet retains the clarity and resolution of its predecessors. The soundstage is also larger and revealing, allowing you to listen to things that weren't before, and also enjoy your favorite models in a new light.

A wider soundstage can also give an enhanced sense of depth and place. The spherical driver of modern closed-back magnetic headphones such as the Oppo PM-3 may also make them sound too wide, particularly when the sound pans from left to right. The HIFIMAN HIFIMAN is built with a more symmetrical design to give a more precise stereo sound.

While the benefits of an expanded soundstage are obvious but most users will find that they prefer a more balanced and neutral tuning for their Headphones planar. The majority of planar magnetic headphones are available with open-back and closed-back models. The latter is a more convenient and traditional design that can be used on a regular basis.

Precision

The planar magnetic driver inside RHA's CL2 headphones produces a sound that is incredibly precise. The driver is small and compact, containing a 16-micrometer diaphragm perfectly suspended over two magnetic fields that provide superior sound up to 45,000 Hz.

The diaphragm also has a more uniform molecular structure compared to traditional cone drivers, which means that there's less distortion across the frequency range. This allows for more natural dynamic response.

To further reduce distortion the diaphragm is placed inside a precisely-machined aluminum housing. The resulting design is lightweight and headphones Planar robust, with a smooth internal surface that encourages uninterrupted flow of audio waves from the microphone to the speakers.

These features create an audio system that is amazing regardless of the volume you choose to play at. The soundstage is large and engulfs your headspace with an unmistakable separation of sounds which gives an impression of depth, allowing you to hear every detail in your music.

The Glasgow-based company makes use of top materials to create the CL2 headphones. They make use of zirconium dioxide, a near-indestructible substance that's used to create synthetic diamonds as well as to protect jet engines. The stainless steel housings that are ultra-thin are tough and scratch-resistant with a matte-finish produced by superheated plasma.

The CL2s are the first planar magnetic portable headphones that offer Sennheiser MOMENTUM 4: Crystal-Clear Wireless Headphones for Calls listening due to their Bluemini adapter and Bluetooth 4.1 support for aptX and AAC streaming. The CL2s come with detachable 3.5mm or balanced 2.5mm cables, which have copper with oxygen-free cores to ensure that analogue signals are transmitted to the headset without distortion.

Soundstage

Audiophiles always want an expansive soundstage that is spacious and large. Audiophiles are not like some listeners who like to jam Taylor Swift on laptop speakers. They want a detailed and wide soundstage so they can fully immerse themselves in the music.

The quality of the soundstage is largely dependent on the acoustics of headphones and how they "present" the sound. Understanding how headphones are designed and made is key to getting the best soundstage out of them. The design of the earpads as well as the headband, and the microphone play a major part in the soundstage.

For example the size of a headband plays an important part in how spacious and open the soundstage appears. A bigger headband will result in a wider soundstage with less distortion. The quality of the earpads are an additional aspect. The earpads need to be comfortable and seal well to minimize unwanted noise and resonance.

Clarity of each instrument is an additional aspect of the soundstage that headphones provide. A clear soundstage makes easy to differentiate between different instruments and vocals in a song, even at higher volumes. Similarly, the clarity of the bass is vital to a headphones' overall sound quality.

Planar magnetic headphones have a greater bass response than dynamic drivers. While dynamic drivers have a smaller diaphragm which is vibrating in response to electric impulses sent by the voice coil Planar drivers feature larger magnets that move the entire diaphragm. This results in a flat wavefront, rather than the spherical wavefront that is focused that is present in dynamic drivers. This helps to localize sound better as it enters your ear.

A flat sound wavefront also requires more power than a spherical, so headphones with planar designs use bigger magnets and require more powerful amplifiers. This is why headphones with a planar shape are typically a bit heavier and bulkier than dynamic headphones.

Distortion

The distortion you hear from your headphones is the result of the voice coil moving between two places in a cyclical manner, compressing and decompressing air around the speaker diaphragm. This causes the various points on the diaphragm to move out of phase which causes the sound to become muddy and distorted. Planar magnetic headphones have a lower distortion rate because the drivers apply the same driving force across the entire flat surface. This results in a low distortion even when volume is high.

Planar headphones also have wide frequency response. They can reproduce a variety of frequencies, from deep bass to high treble. They also have an immediate transient response. This means they react quickly to changes in audio signals.

While planar headphones have many advantages but they can be difficult to drive without an external amplifier. They typically have larger magnet arrays than dynamic headphones and require higher power to operate. There are, however, highly efficient planar headphones that can run directly from mobile devices and desktop audio players.

The CL2 planar magnetic earbuds by RHA is made with an oxygen-free, conductive core and a bespoke neodymium magnetic material to provide greater efficiency. They are compatible with all Bluetooth devices and can be used wirelessly or via wired connections. The cables are available in 3.5mm, balanced 2.5mm and premium materials. They are also braided to ensure durability and strength.

There are a myriad of options for Bluetooth planar headphones, or even just a set of good headphones to listen to music. It's important to consider your budget and your preferences for listening before deciding. It's tempting to purchase the most expensive headphones, but you might find that they don't sound quite as great as a pair of cheaper ones.

Leakage

Planar headphones, as the name suggests, use a flat membrane and magnetic fields to create sound. They also have a much thinner diaphragm that's often less than 80% of dynamic drivers. They can produce a richer sound and have more detail than their larger counterparts. They also require more power. While some headphones, like the HIFIMAN DEVA can run off a mobile phone, most require a separate headphone amp to ensure the best sound.

Planar magnetic headphones emit more sound because of their bidirectional movement than those that use a voicecoil transducer. They are therefore not suitable for public use, especially in situations where you don't wish to disrupt other people. However this is not a problem when you select closed-back headphones that have a secure seal to stop the sound from escaping.
