So comfortable you barely notice them, even after having them on all day. The sound is just Nice. You can give a list of imperfections, sure, but compared to normal headphones they sound perfect, warm and clean.
I was used to Sony Extra Bass and dynamic driver IEM's so the bass felt a bit shy, but with the right amplification I very much like it. Also worth noting that they sound very isolated for open backs (in a good way)
For the price and if you like nice sound, I would very much recommend.
Everything about these cans are top notch for the price. The quality of the materials, the comfort of both the headstrap and earpads and of course the sound. I do wish they were a bit "punchier" though, because although the sound is very good and soundstage is good and all that, even with a strong amp you don't really get the kick and intensity of say a pair of HD650's (which I also have).
It is worth mentioning to anybody buying this pair that you should definitely try to EQ them. AutoEQ works perfectly fine for me, but you should experiment a bit to see what really brings out the best qualities in terms of sound that these offer.
Overall 9/10 for me, and only brought down slightly by the lack of punchiness.

Good audiophile headphones
Sound profile wise they are warm.. they aren't the most comfortable for me which is my only complaint really... Otherwise very solid headphones excellent tonal balance decent sound stage etc...
As with my Aeon Closed X the sound on my FiiO R7 is great through the Aeon Open X, but the comfort is unmatched, I could wear these for days at a time.
I finally found headphones that do not tire me with their sound characteristics in the long run. So if you are looking for something to relax after a hard day or to listen in the evening for pleasure and not analysis, these headphones are the way to go. I recommend.
A lot of reviewers suggest the closed are more accurate and technically better. I disagree. There’s something thin and brittle about the midrange of the Closed X that completely ruins guitar tone, significantly altering it. The Open X do not suffer from this at all - although they do have more treble extension than I’d like - again a lot of headphones do this to chase detail at the expense of tonal accuracy. However, using the pad recommendations of Z from YouTube (the default white plus the soft foamy black as a combo) these sound pretty awesome. I don’t like to EQ as I use these on multiple devices, including direct monitoring of guitar through a mixer. Some music can still sound a little too bright, but for the most part these become well balanced without sacrificing detail. Guitars in particular (I’m a guitarist) sound terrific, as do vocals. I returned the Closed X, sold the HD6xx, kept the Open X. Other headphones I’ve owned before these include: Noble K10u, Ether C, LCD2, HD6xx (twice but never liked), AirPods Max, RS1i, DT880 Pro (twice, nice but spikey), and a host of different IEMs from Shure, Westone, etc.
The only issue I have is that despite being soft, with fairly light clamping pressure, and being open back, these still somehow cause a bit of clamping pressure after half an hour and need to be shifted around or taken off for a bit, and they get hot. Far more comfortable than the Ether C, HD6xx (terrible), LCD2 (heavy) and APMax (heavy).
high quality build / very comfortable / very clean sound / well worth the price
I'm really enjoying them. They are very comfortable, light and the sound is balanced with a clean strong planar bass (they need to be EQ'ed to harman target first though). I'm so impressed with them that I'm going to buy the closed version next, which reviewers like Resolve and DMS say is a superior version.
Pros
They are very well made using a combination of metal and high quality plastic
They have the best stock earpads I've ever had
They need EQ but after applying oratory1990's harman_over-ear_2018 profile the sound is well balanced with a strong clean planar bass.
