Based on its work experience, AKG has formed a team to produce Austrian audio. They have produced microphones and 2 headphones, the on-ear Hi-X50 and now the over-ear version Austrian Audio Hi-X55.

Following this, Austrian Audio Studio is producing and developing microphones and headphones designed for use.

Austrian Audio Hi-X55 : Design

Austrian Audio Hi-X55

When it comes to design materials, it is mostly made of metal body. Especially operational parts. The bow of the headband uses metal rail inlays with grooves that serve as guides for the adjustment mechanism.

The adjustment method is very robustly develope by the company. Thus, you will not have any problem in adjusting the size you want. But, when the headphones are on your head, it is a little harder to adjust. So coincidentally changing the fit of the headphones while wearing them can be avoid.

The Hi-X55 has hinges for folding them for travel and rotating the ear cups to get that perfect fit on your head. The hinges on the headphones are smooth and feel quite strong.

It seems that the Austrian audio likes velcro very much, as they also used it with a removable cushion on the top of the headband. I like that they glued it instead of velcro, at least this way it would be easily replaceable by the user.

Moreover, the Hi-X55 headphones are a single entry compact disc-shape headphone design with a portable 3m cable. The cable is abort in a 3.5mm TRS connection with a screw-on ¼ ”adapter. While the other end has a bayonet lock with a 2.5mm TRS connection.

Therefore, the Hi-X55 has a single entry system. Because of this, the internal wiring from left to right of the headphones is uncover. The wire is distort in such a way that it will be difficult to coincidentally slit on the wire.

The earpad on the Hi-X55 is also dispensable. There are 12 clips on the ear cup that hold it firmly in place, but the earpad can be easily replace by user. Earpads are made of memory foam, which is soft enough to suit the shape of your head.

Austrian Audio Hi-X55 : Comfort & Isolation

Austrian Audio Hi-X55

At first glance, the Hi-X55 looks like it has a small supraorbital ear cup, but the earpad has thin walls so that the inner diameter of the earpad is larger than you would expect depending on the ear cup which makes it a compact circular.

The earpad is thick and compact enough to feel like a pillow on the sides of my head. Thus having an ear pad in front of the side of my head will not cause any problem of comfort. Another added benefit of having thin-wall ear pads is that they will not warm the side of my head even though they are made of leather.

When I adjust the headbands, I adjust them to a maximum of about 1 notch, which is respectable. The adjustment mechanism is so large that it can assist a wide variety of head sizes. Although there is some foam on the top of the headband, any small size adjustment will give me a warm spot on the top of my head.

While the earpads on the Hi-X55 are thin, they stand out. And with their closed nature, they make a good passive seal around my ears. They can keep the sound inside and create an overall immersive sound environment.

Austrian Audio Hi-X55 : Audio Quality

Austrian Audio Hi-X55

Simply put, the Hi-X55 puts recordings for observation. They provide low-frequency information with straight-edged rigidity. Giving the bass sound a proper weight and speed but controlling it to some extent approaching. Their midrange resolution also allows you to see a direct and colorless view of what’s going on – and, in the case of singers, an understanding of technique that is virtually forensic.

At the top of the frequency range AA stays to the right of the clinical. Trouble sounds have substance and sting. And – if the recording is master in this way – there is a lot of luster. But the Hi-X55 resists hardening at the top end, even if you really decide to increase the volume.

However, for all their powers of insight and analysis, nothing is indifferent to what these headphones sound like. They are more than happy to track the dynamic peaks and licks of the recording, they integrate the occupants of the sound stage, in one performance, they have many near-field monitors instead of making them sound like a number of different elements. Sensitive to. They also collect appropriate rhythmic expressions. Which is more than just for many competitive designs.

Not the most exciting thing they can do to buy that kind of money, that’s for sure, but it’s going to miss the point somewhat. The Austrian audio Hi-X55 will tell you everything you want to know about the recording, without getting all the laboratory assistants. Which is a talent in itself.

High Excursion Technology

Look Like a Professional Headphones

Hi-Xcursion (High Excursion) technology is the key to the amazing sound of our Hi-X55 headphones.

All Austrian audio Hi-X headphones have a 44 mm driver and ring magnet system. This design allows to improve air flow and includes the strongest magnetic field in its class.

The ring magnet, attached to the copper-clad aluminum voice coil, reduces the weight of the membrane and the voice coil attached to it, allowing the membrane to move quickly or change direction, providing a more responsive impulse response.

Our science, measurement and hearing tests have shown that 44mm is the best size for this design. It ensures professional operation in Hi-X, removes a lot of air and eliminates diaphragm ‘wobbling’. This is like wetting the driver mass, where our membranes actually show results: it is ultra-hard while still reducing unwanted resonance.

Austrian Audio Hi-X55 : Connectivity

In terms of connectivity, Austrian Audio Hi-x55 come with a portable 3m cable. The cable is aborted in a 3.5mm TRS connection with a screw-on ¼ ”adapter. While the other end has a bayonet lock with a 2.5mm TRS connection. Because of this, it does not support for any Bluetooth Audio codec, Bluetooth and Bluetooth multi-point connection.


When Austrian Audio’s marketing team introduce that these headphones were design for studio use. I was worried it might not be fun. The Hi-X55 can mean business in many ways, but it still hasn’t burried how to have fun when it comes to hand over a natural and easy bass response.

The design has a utilitarian feel, and many practical deliberation had to be made to secure durability. Regardless, the Hi-X55 was adorn with some plastic parts to smooth out the edges and make it look stylish even with being so strong.

While I can’t see how the Hi-X55 is root in previous AKG products. The team’s experience evolves through design, tuning and refinement. Despite being design by a relatively new company. The Hi-X55 is a very mature product that should not be limited to just the studio. Plenty of regular audiophiles will also enjoy this.
