I upgraded to these from a cheap pair of headphone. What a difference. Now it seems like I am there whatever music I am listening to. Never expected such a vast difference. And comfortable too.

Comfortable to wear--good sound clarity--worth the price

These are, by far, the best headphones I have ever used. I have heard things that I've never heard before in music I've been listening to for 40 years! They are very comfortable and solidly made as well.

Excellent quality. Picks up voice and dampens out all the noises. Remember to pick up connectors for what your using it for.

better than i thought. sound great.

These are the most outstanding headphones I've ever used. Phenomenal sound (paired with a Dragonfly Red). robust construction, incredibly comfortable. Strongly recommend if you're in the market for a midrange headphone.

I used two of these baluns to connect a Buttkicker transducer attached to the sofa in my home theatre to the subwoofer output of my AVR over CAT5. They work well, and only requires simple plug and play operation. This allowed me to use the existing CAT5 in my home to connect the second sub, so I didn't have to spend a ton of time fishing and running new cable to support the new sub. So while these products are seemingly expensive for a passive device, if you already have the UTP infrastructure available you can save a lot of time and effort using them instead of pulling new cables. Look for other Muxlab baluns which will allow you to run all kinds of things across UTP. (eg. CCTV, audio, video, hdmi, component video, stereo, vga ect.)

This is my second Austrian Audio product (I also have an OC18), and I can say for sure that the company has a commitment to build quality. These things are absolutely gorgeous. They are also fairly light weight and incredibly comfortable to wear for long periods while working (for me, typically, 6-10 hours a day). Another concern was ear cup size, as I've got fairly large ears, but there's plenty of room in there.



As for the sound, I love them, with one big caveat: In my opinion, these are not at all for someone who casually wants to sit down and listen to music. While they have a great soundstage for closed-back cans, they are neutral and very clinical. You're not going to get that huge bass bump, and smoothed out highs that you find in the consumer-focused market. You will hear every fault with both the performance and mixing/mastering. That said, I do enjoy them when I've had music on in the background when I was too lazy to swap them out for my Beyerdynamics.


I'm using these primarily for audiobook production/post-production work, and they suit me perfectly. Both in the booth while recording and out of the booth for proofing and editing, they are bang on. In the booth, they allow me to hear my voice (which is in the baritone range) quietly, while accentuating mid-and high-range noises that might be easier to rerecord, rather than deal with in editing. Also, the leather ear cups are tight enough to prevent any bleed into the mic, while still remaining unbelievably comfortable.


During post-production, again, they help block out unwanted external sound so I can hear what I'm working on, while providing a focused reference for what is happening in the recording--good and bad.


While I can't speak to how they would work in a studio setting for musicians, I can absolutely recommend them for VO recording/post-production.

My reference for years has been the Sennheiser HD650, and I've been an open-back guy ever since I first heard them. But the AA Hi-X55 is better in nearly every way, especially in comfort and detail. It may lack just a bit of that airiness that is the signature of open-back 'phones, but in staging and definition it's a significant step up. I can't speak to durability--only a week in--but so far I am thrilled. Highly recommended.

I bought it for my 6 and 9 year old sons they love it, it loud and to sound is great.
its also reasonable price
