The core team at Gold Planar began designing and building quality audiophile headphones in 2010 as a major manufacturer for some of the most reputable brands in the industry. In 2017, Gold Planar was officially established as its own purveyor of boutique Hi-Fi headphones, with the goal of creating the highest line of reference headphones. Today, Gold Planar uses all of its years of knowledge and experience to design proprietary in-house planar magnetic diaphragm drivers that exceed the performance values of modern day standards. Gold Planar planar drivers are used by other manufacturers of top-end headphones, and are often regarded as the best in class. Gold Planar is proud to now be designing its own headphones under its name that boast their expertise and talents. We invite you to experience the original planar magnetic driver headphone in all of its fullness and audio glory
The GL400 is an open-back style headphone with perforations in the outer cover, allowing a natural flow of air through the headphone. This creates an extremely coherent and life-like soundstage. The GL400C is a closed-back style headphone that blocks out outside noises for a more isolated listening experience. The design of the outer shell creates a natural and reverberant atmosphere, perfect for every genre of music.
The GL400 was designed to be an extremely portable Hi-Fi headphone made for the on-the-go audiophile. Weighing only 160 grams (GL400) and 190 grams (GL400C), the GL400 is incredibly light yet durable due to the aerospace-grade aluminium and leather construction. The GL400 utilizes Gold Planar’s proprietary ultra-thin nano membrane planar magnetic drivers that takes the full advantage of the powerful N50 magnet. The engineering behind the GL400’s driver design creates a uniform magnetic field that is evenly distributed across the membrane. The nano membrane’s thinness allows extreme responses that brings out every minute detail. The overall result is a highly sensitive and consistent sound that lacks any form of distortion. The GL400 thus boasts one of the highest resolutions in headphones of its size. With a frequency range of 10Hz to 50kHz, you can experience the most powerful bass and the most detailed trebles. The GL400 was tuned with a balanced sound in mind, so you can experience a natural presentation of the music, with warmth, transparency, and clarity. With the option of using balanced headphone cables, you can also take the GL400 to new heights with the extra input power. The comfort and audio quality of the GL400 will have you wearing it all day long

Out of the box there was an emphasis in the 200 to 500Hz range. The driver was under damped. This caused the reverb in recordings which mostly reside in this frequency band to overpower more direct sounds. This is the cause for slightly muddy sounding lower midrange.
I made another foam pad from packaging foam & placed it behind felt pad pushing the felt pad more firmly against back of driver. There was hardly any pressure before hand. I also made a foam pad for front of driver which I used to hold a piece of knit fabric I obtained from a T-shirt which is pressed against front of driver. These modifications improved the damping quite a bit such that the 200-500Hz peak is a thing of the past. Now the sound is very even from 40Hz all the way to as far as I can hear which is about 14KHz which is great. I took them to a friend of mine who is world famous audio electronics engineer & he thought they sounded great. He loved how dynamic they sound compared to most hifi headphones. The difference is not subtle. It is huge. Very hard hit snare drums sound very hard hit, not subdued as it does on my Senheiser HD579's. Yet everything sounds natural & organic. Subtle sounds are subtle but unlike the other phones I have are extremely clear but in a natural way.
It is hard to put these down in spite of how uncomfortable they are on my ears due to the fixed position of the earcups. There is no pivot vertically, only horizontal swivel. They sound absolutely phenomenal for price.
