Hi-X55 : Great headphone, not for everyone

The build quality is top notch. Tho I have to mention that the rotation of cups is a lot looser on the left side on the right, but other then that, a very well made headphone.

Tho I am worried about clicking I hear from the plastic bits when the headphone clicks to place. When adjusting my headphones on my head with not much force, you can hear the metal parts move against the plastic as if it's going to take the plastic apart.

That was the bit from my K550 headphone which broke too and it looks similar.

If you mix mostly on monitors, certainly get them to check problems areas on. They will stand out immediately. I especially liked them for vocal work (both interview and music vocal mixing.)

However, I feel like the comfort is lacking which is a shame.

Many reviewers praise it but I have a feeling that they don't sit more than 4 hours with it on. It's a tad too heavy which also causes the headphones to creep forward every time you look down.

This sucks because the passive noise reduction is absolutely fantastic.

Also something to look out for is that the cable is really loud compared to other headphones which is annoying when drumming/moving with them. From 40cm down the cable, if you softly tap on it, it sounds like someone is tapping on the cup directly.

Soundstage is fine.

Still debating whether I am keeping this since I do sit for long hours with them on.

EDIT: after mailing with Austrian Audio, the loose left ear was indeed an issue with my specific headphone. This is also what caused the discomfort.

I want to leave this review up incase anyone else has this issue but I did adjust the stars according to as if my headphone would function like most likely your new one.
