Ok, for the benefit of mankind and the generations to come, here the results of my highly objective and indisputable tests.
Mobius vs ATH-M50XBT (modded with the Brainwavz Angled Sheep's Skin earpads): it was a tough one, I really liked the ATH and I was so proud of my obsessive days of A/B (2 ATH-M50XBT with different earpads, 1 ATH-M50X, 1 Mobius) thanks to which I've found the almost perfect earpads that made them sound, to my imperfect ears, even more neutral than the wired sister.
They are more present than the Mobius in the upper half. Which is good. The Mobius lack there.
Between the dip in my ears, the dip in the Mobius around 5Khz (see review in Rtings), the nature of planars, and the artificial soundstage of the Mobius where some instruments get a bit lost, I felt and feel a lack of vitality there, in general, and specially in the upper half.
The ATH are also lighter and (with the new pads) more comfortable.
But the Mobius had something... A roundness, which makes them more gentle on my ears in the long term. A better albeit artificial soundstage, more separation, more precision in the bass while still being fairly neutral.
And well, can be used with USB, have LDAC (useless for mixing but nice for fun), have this 3D thing, presets...
So. Mobius won.
Mobius vs Aventho Wireless: why Aventho and not Amiron? Ask Beyerdynamics. They told me the Aventho are more neutral and suggested me those over the Amiron for production.
So, I've received, tried, and in 2.2 seconds I knew they had lost. I mean, the Aventho had lost vs Mobius. And Beyerdynamics had lost, their mind.
I don't know nothing about Tesla drivers, but, these headphones need caffeine.
They're not neutral. They're just not alive.
Not even the MIY app, which compensated for the dip on the highs in my ears, could save them.
There is almost zero soundstage. The bass is somehow muddy and pumped.
They sound even darker than the Mobius.
They had also a very noticeable hiss.
And despite being so much lighter, the designer preferred form over function and the junctions of the headband touch the head. Not nice.
Instant return.
Mobius vs Ora Graphene: here I couldn't take advantage of the German Return Right. No Ora here.
I was just about to pull the trigger on an eBay auction for an import from USA.
But I've found a thread on Head-Fi about them, and a few people there had the Mobius too.
So I asked them which one is more neutral.
I was told Mobius.
So, the Ora didn't get a chance.
I stay with the wish to try them.
But Mobius it is.
Mobius vs PXC 550-ii and vs ATH-DSR9BT: I just trusted Rtings and decided not to abuse any further of the Return Right. I've just let go of the obsessive need to compare them too.
Now, I've just ordered the Gel Pads for the Mobius.
I'll come back with my impressions.
I'll also test the AKG K371-BT as soon as they're available. I'm very very very skeptical about the absence of any better codecs than SBC. But, they made them for studio, I must try them.
The Nuraphone remain a curiosity, but I just don't feel that monitoring with something sticking into my ears (besides the reviews about how they make your ears hot) is emotionally convenient.
So.
I think I'll get Morphit, they support Mobius.
And I'll follow the suggestion received in KVR and I'll get a hearing test. Definitive one online, probably also a professional one here locally.
I'll get my EQ Curve, and I'll transpose it in Morphit.
Many people use Morphit with CanOpener, I might try.
That was.
My quest is, at the moment, ended.
And the moment when I understood it was ended, is when I saw the Mobius (I have the copper version) near my Apogee HypeMic.
I think that style is also important.
Colors must fit
You have some dedication.
