After the immense and ultra impressive sonic prowess obtained from the Elysium earphone, Vision Ears wanted to continue to improve on it’s electrostatic offering and have launch the EXT ears. Listening to the EXT will bring you closer to the true spirit of the sound. The four electrostatic drivers create a wide open landscape of lush detail that never feels exaggerated. In combination with the electrostatic drivers there is a 9.2mm dynamic driver, with loads of power in the very low end and a 6mm driver for the midrange. The EXT is able to uncover the uncompromising beauty and greatness of your music.

The EXT exclusively features the 2nd generation of Vision Ears’ HALC (High Precision Levelling Chamber). Finely tuning the sound of the dynamic midrange driver to it’s highest accuracy.

Based on the idea of the ELYSIUM to create an electrifyingly detailed but also warm and embracing sound, Vision Ears wanted to explore what is possible. They wanted more. More lows that make you feel the rumble. More mids that vividly embrace you. And more highs to bring an airy and elated experience. The feeling of an electrostatic headphone is unparalleled and hard to achieve with a small earphone. The EXT will prove that wrong. An easy lightness surrounds this creation, airy, silk-like notes gather around your head, musical areas you never recognised will unfold before your closed eyes, a truly electrifying experience.

The Design

The idea was to create a technical but elegant shell with the aesthetics of an open back headphone. The most captivating element of the EXT is the purple machined faceplate with the prominent and magnificent X design. The complex CNC machining was optimized for this project to realise the delicately shifting lines of the design. The elegant deep purple colour anodisation is a special VE custom colour, proudly showing off the VE brand. A vacuum metalized mesh is elegantly sparkling underneath the open structure of the X design. This special aluminium acoustic mesh is giving the dynamic drivers the air to breathe and unfold their rumbling power, while protecting the internal components from outer influences.

The shell was made of solid black acrylic in a semi-custom shape. A black transparent area allows you to have a discreet peek on the green HALC and the four electrostatic drivers.

The Case

The EXT design is prominently covering the finely machined aluminium case. A striking and unmistakable look, showing the remarkable design of the EXT. The machining of this case was made with extraordinary precision, to make the two parts of the case fit perfectly together. The inside walls are all covered with a rubber inlay, so that the earphone is always protected when you are on the go. A premium leather pocket holds the earphones in place, preventing them to collide during transport.

Custom made cable

The EXT comes with a premium 8 wire spc 28AWG cable with a balanced 2.5mm connector as a standard. With the all new VE Adapter you can simply change the termination from 2.5mm to 4.4mm. This premium adapter comes with a gold-plated phosphor bronze conductor and audio grade POM insulation.


The EXT uses an all new 6mm dynamic driver for the middle frequencies, finely tuned by the 2nd generation HALC, a widely praised tuning concept introduced with the ELYSIUM for the first time. Additionally to the levelling chamber of the HALC Vision Ears use an STC (Side Tuning Chamber) that allows the midrange to be precisely tuned on the vocal range. The result is a smooth and rich presence to the middle frequencies. Vocals are full and rich, performing with a vivid and natural tone.

Technical Specialities


An improved HALC tuning concept was exclusively developed for the midrange driver. Additionally to the levelling chamber of the HALC Vision Ears use an STC (Side Tuning Chamber) that allows the midrange to be finely tuned on the vocal range. This new generation is giving many more abilities for tuning and in the end a significant higher level of realism in the midrange.


The technology of electrostatic drivers is well known to high demanding audiophile people but they were yet mainly equipped in high class headphones. In the recent time this technology is gaining more and more ground with IEM´s all over the world, making the huge benefits of electrostatic drivers now portable. Due to a voltage transformer inside the earphones shell the electrostatic tweeters don´t need any external power source but only a high quality and powerful amplifier inside your DAP. The first generation of the Sonion EST drivers have been introduced to the market in 2019, now the second generation is state of the art. Due to their higher output SPL and using two EST dual drivers, the EXT is able to increase and extend the output to a whole new level.

Dynamic Drivers

The 9.2mm dynamic for the lows and 6mm dynamic drivers for the mids are equipped with a Liquid Silicone Rubber (LSR) surround. This technique of making the surround of rubber allows the driver to perform with a very low THD (Total Hormonic Distortion). The Al-Mg Alloy diaphragm of these drivers are light but stiff, which makes the performance surprisingly fast, very deep and precise. A Super Strong Rare Earth N52 Neodymium Magnet, allow the drivers to perform better in more demanding situations, with less distortion at any operating level. In addition, they have added to the 6mm driver a double N52 Neodymium Magnet, to decrease even more the THD and increase the SPL without increasing the size of the driver.
