Gold Planar headphones

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 bring 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.

Built quality

The GL-400C is obviously budget-priced but the build quality does not show any cheapness at all. Gold Planar claimed they used light aluminium to construct the enclosures of the headphones. Every part of the headphones felt solid. 

Portability with high fidelity. 

The GL400 was designed to be extremely portable Hi-Fi headphones 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 nanomembrane planar magnetic drivers that take full advantage of the powerful N50 magnet.

GL400 and GL400C. 

The GL400 are open-back style headphones 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 are closed-back style headphones that block 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.

Top-selected driver 

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.

Comfort

The headband does have sufficient padding, which sits comfortably on the head. The headphones feel durable, the ear cups have thick paddings (synthetic leather). 

Mids and vocals

The mids are clear and nicely layered, aided with a wide soundstage that rendered very good stereo imaging. 

Bass

The bass coming from G400/G400C is quite impressive.

Treble

The high frequency is where the GL-400C shines. Within this price range, there is nothing comparable to the level of clarity and detail in the high-frequency reproduction

Tuning style

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!

Gold Planar team

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.

“Excellent! The cheapest headphones in their class I've ever seen, but they still sound good! The only nuance is the landing. They are not around the ear but sit on the ear. The rest is a bomb, I definitely would recommend them!”
