Nach längerem Hin- & Herüberlegen hab ich mich doch endlich für Austrian Audio entschieden.Nachfast 2 Jahrzehnten Musikproduktion und Sounddesign kann ich sagen, hier stimmt die Qualität.Und auch der Preis ist angemessen im Anbetracht dessen was geliefert wird.Toller, voller, aber dennoch gut neutraler Sound, sehr guter Tragekomfort, auch über längere Zeit.Wirklich recht präzise in der Klangwiedergabe.Für elektronische Musik jedenfalls geeignet, für klassische Musik soweit ich das momentan beurteilen kann, auch sehr angenehm ausgewogen, aber auch schön neutral.Kein Hi-Fi Produkt. Analytisches Hören geht aber ganz fein.Je nach Geschmack, sehr zu empfehlen!

Headphones are incredibly comfortable and seem very well built. I was/am concerned about the headband issue that others have noted, but Austrian Audio offers 5-year warranty so I was willing to accept that breakage prior to 5-years is hopefully covered.If you don’t care for the sound profile these are extremely easy to EQ and can reach adequate volumes from all devices I’ve tried.

These sound absolutely lovely. The detail is incredible, with a great soundstage and crisp, clear mids and treble. But at the same time, they're not tiring to listen to: they still have some warmth. Comfortable too.

J'ai long cherché un casque qui pourrait correspondre à mes attentes (et a mes grandes oreilles) et le Hi-X65 n'a pas déçu.D'une qualité de construction et rendu sonore bien au delà de son prix.Capacité de détails égal où supérieur à des casques 3 fous plus chers.Rien d'autre à dire sauf qu'il est parfait a tout niveau.

En el terreno de la reproducción musical HiFi hay un espectro incontable, muchas especificaciones técnicas, datos, revisiones, pero la única básica y determinante es la que te ofrecerán tus oídos.Solo te puedo decir, la calidad de construcción y comodidad de estos auriculares es magnífica. En cuando a su sonido, es muy equilibrado, neutro, analítico con un espacio de escenario amplio que te da una sensación 3D.Repito, no quiero caer en comparativos técnicos, lo que describo es porque me han dejado muy satisfecho y sobresale a una banda de auriculares que yo tengo de gama media y alta que me permite afirmar el gusto que me han proporcionar estos auriculares, de una marca tal vez no muy popular y conocía en el mundo, pero el respeto que trae de origen hace posible decirte que es un auricular excelente

What is there to say that hasn't been said? They sound fantastic, and they're built like a tank!

Looking for the pro sound headphones without breaking your bank? This one is to go. Amazing volume sound, crispy as the spring air

UPDATE: I gave these headphones five stars for sound, review below; they are absolutely fantastic performing and comfortable headphones. Unfortunately, there is a fault with the plastic connectors where the headband slides in and out for sizing. These plastic pieces crack and break apart very easily, and it sounds like (on forums) this breakage has happened to many many Hi-X65 owners. Austrian Audio does honor their warranty and replace them, as they did with mine. But, the new set has the same thin plastic piece and I assume it will crack again sooner rather than later. It is at a stress point that gets pressured every time you wear them, so it is not possible to avoid breaking them by being careful. They both broke, on both sides, on mine. See picture. A few healthy dollops of JB Weld fixed the problem, and the headphones are thankfully the same grey color as JB Weld, which is great. But, still, not very elegant. When my new pair breaks again, I will just do the JB Weld repair and keep them. The warranty exchange process with Austrian Audio was bumpy and haphazard but eventually they exchanged it.Also, I'm very worried about what happens when I need new ear pads or a cable. Both of these items are proprietary and specific to only these headphones, and Austrian Audio does *not* list replacement ear pads, head band pads, or cables for sale anywhere. This is very strange, as these parts were clearly designed to be easily replaceable.———-My original five star review:I absolutely love these headphones! They are so comfortable and well made and the sound is comfortable and easy going and warm, as well, but also with lots of detailed extension into the highs and lows.To sum up my love for these headphones: they are extremely detailed, with a beefy warm boost in the low mids. Every other set of headphones I compare with these sound thin in comparison. The airy highs are rolled off a bit, they are still there, and articulate, and you can boost them with eq for a full clean sound, but the air is reduced in intensity by default it seems. This makes long listening sessions very very easy and comfortable. Bright mixes with shimmering fiddle overtones for example have everything there, just with a warmer balance overall. For mixing, if I need to use headphones, I will switch between these and my Austrian Audio Hi-X15s though because the Hi-X15 are not warm at all and much brighter, so they can reveal problems with harsh highs that sound totally fine on the Hi-X65. But, if your mix has too much low-mids, wow you will definitely know it right away on the Hi-X65s. That's usually the problem area in a mix where sound builds up, so I can see why they made sure the low mid frequencies were strong.They feel expensive and sturdy. The cups are large and they give me plenty of space for my ears and my fairly large head. There's a fair bit of clamp force, as others have mentioned; it has settled a bit over the past month but is still significant. I have an extra large head, both in height and width. These fit. After a few days I realized that I wasn't extending them far enough (after seeing myself in the mirror) and they still had plenty of clicks to spare. Getting them extended properly did improve the sound, I'm glad I noticed that!Oh and I like how very efficient and easy to drive these headphones are. These are no problem to power at very modest volume settings (about one third volume) on my phone, laptop, or portable CD player, with no need for a specialized headphone amp. That is key, for me, because if I'm going to listen using these headphones then I need to be able to use them any time without having to fuss with a bunch of separate hi-fi audio components. I just want to plug them into a regular headphone jack and use them. Check! My old Sony CD Walkman from 20 years ago needs the volume set to about 40% for normal listening levels. My laptop computer with its built in headphone jack is at about 20%. Easy peasy. Funny enough, though, the xCAN bluetooth headphone amp needs to be cranked up to 60% - go figure! It sounds great though on the xCAN. I wanted to assume that it would sound the same, but honestly I can't find levels where these sound exactly the same on my MacBook compared to the xCAN preamp; the balance and the detail really is different. So, I guess the sound you get from these can technically depend on the headphone amp, though they work great on any well-made consumer device.

UPDATE: It's now April 9, 2024. Had these about a year and 3/4 months. They sound BETTER than ever. These have become my "maybe" end-game headphone to MY ENDGAME. There was a small issue with the wiring - not sure why it happened. I reached out to AUSTRIAN AUDIO, and they possess the best Customer Service, Kevin, who helped me get what I needed with love and care for the product. Based on that customer service I'm a customer for life. And these cans have never sounded better. One of my all time best purchases. Thank you Austrian Audio & Thank You Kevin!Not an audiophile, but I love high-end headphones. These are my first open-backs, and they are amazing. I've had for 2 months and they keep getting better. Maybe the best I've ever had including more expensive cans. I had the Sundara for a month and these blow it away in my humble opinion.UPDATE: They sound even better. Nothing compares. I feel like when I hear a good source (I use qobuz or my own high-end files) it's just giving me all the song got. I hear it all - tremendous detail and comfort that i often fall asleep in. Endgame. (until the next ones.)

These headphones sound phenomenal the build quality is impeccable the open soundstage in the natural Sonic characteristics are incredible I can't say enough good things about these headphones and frankly I will buy these again very soon and I will buy them from the same people at Kellards because because of lack of communication on my part I made a snap in judgment which I resend and I think that Kellards is a very stand-up seller and I won't hesitate to buy from them again.

I don’t normally post reviews but I just had to post one for these criminally underrated headphones. I have been a headphone addict for at least 12 years and I can honestly say that the Hi-X65 is one of the best headphones I have ever heard.If you are looking for headphones that dissect the music and present it to you with amazing imaging, instrument separation and detail, these are the ones to get. The detail… it’s what so many other headphones strive to achieve but fall short compared to the X65. Also these somehow have some of the best instrument separation I’ve heard under $1000.To top it off, these headphones are super easy to drive, I get AMAZING sound from these from my iPad with just the Apple headphone adapter.If there is one downside, and it’s not really a downside, is that the X65s require good quality music. I use Amazon Music HD with these and it’s just fantastic. If you have lower quality audio, these headphones will let you know that it’s bad. If a song has been mixed with hot treble, these headphones will let you know. If there is someone in the back row of the orchestra with a squeaky chair, these will let you know.Now, if you feed these things high quality music, you will just sit there in awe. Whatever the Austrian Audio team did to make these headphones, I hope they keep doing it and I hope word gets out about these and more people get to experience what I have. Amazing cans.

Love the detail while watching videos.

Su sonido sin ecualizar es correcto sin más, pero lo bueno que tienen es que son perfectamente ecualizables, a diferencia de otros auriculares que no mejoran mucho o suenan muy artificiales con ecualización. Por lo tanto si usas un ecualizador paramétrico, como por ejemplo APO si los usas con PC, o Qudelix 5K, o similar, puedes moldear su sonido y hacerlos sonar como auriculares muuucho mas caros. Sus agudos son limpios y nada ásperos, a diferencia por ejemplo de los senn HD560S, cuyos agudos no me acabaron de convencer. Sus graves son detallados pero el subgrave necesita ser potenciado por EQ. Las frecuencias medias suenan claras y detalladas. En definitiva, que con EQ los puedes convertir en analíticos, cálidos, etc... de hecho he configurado varios presets de EQ y en uno de ellos suenan como mis impresionantes Anker Q30 (otros que con EQ superan a cascos mucho mas caros) y en otro a mis venerados senn HD650 pero 'supervitaminados' con mejores medios y mas agudos, pero igual o mas cristalinos.
