Is there any chance Aptx HD support can be added? All these codecs are free to my knowledge so was it just a time thing that caused it not to be added?
No. They are not free. SBC and LC3 are royalty free through the Bluetooth SIG. AAC is licensed through a consortium (VIA). AptX/HD is a codec from Qualcomm. LDAC is from Sony. LHDC is through HWA. For each one you have to pay separate licensing fee either through the chip vendor or separately for the receiver. For transmitters they may be free. The main issue is the support from the chipset vendor you use. The chipset we use on Mobius only supports SBC/AAC/LDAC.
It'd be great, but I care more about PC and gaming versatility with the awesome sound signatures it comes with for music it's by far the best gaming headset out there for the price; Some additions to the software, some tweaks to the hardware/firmware flashing(&recovery) and headset programming so we can program and take with our own EQ. Small things that allow us to dial in the headset perfect for each user beyond our head settings. For a first generation headset they did great, I just hope they don't churn out a V2 without a lot of added details and consideration on the build quality and people who wear headsets around their neck or off one ear due to work demands. I'd pay extra for metal parts on the yoke, easily replaceable battery, that makes it a buy it for life.
Gelpads are the same depth but do not lose form like the memory foam they wont compress as much or go flat. I've had them for a year i think now and they are the same shape as when I bought them and the memory foam look like squished and angled after only a few months of use for me. They just gotta ditch the foam and make the gelpads the standard even if it costs extra 10-15 dollars.
Thanks for the info, decided to buy it. They already compress a little on the head and don't create that perfect seal, also can build that heat easily. For the number of hours I wear a headphone it makes more than enough sense.
And yeah if we could put our own EQ on the headset itself, that would be something else. Even just a single 'Custom' option. Custom graphical EQ would be peak Mobius for me. Atm I have to route all audio through apps on mobile that support some form of parametric EQ, which means USB Audio Player PRO and Roon. Final thing I think that would make this headphone 'the' headphone.
EDIT: Got the Gel Pads, much better seal, better isolation, resulting more desirable sound. Hard to put a pin on it but its better balanced. It just sits way better, feels more premium. Dare I say soundstage, idk I'd need to do comparison and these are too good to take off.
Also found a port of Equalizer APO that uses 64bit (vs default 32bit) internal audio processing, and redid/updated it for the newest version. Bit clearer vs when its off now, especially when stacking effects like multiple Graphical EQ's.

Result:
Black line is pre-EQ, blue line is post EQ, green line is the EQ itself. Q settings above includes a tweak at 6500Hz to reduce potential sibilance, plus a general -2dB beyond ~3750hz to reduce the treble gain. Easy to adjust treble reduction, its only there to avoid treble shock on enabling this. This was generated in a way that preserves the Mobius brilliance above 10KHz, falloff might have harmed detail and Waves NX locality. Overall this shift the Mobius from a 'dark' headphone to a more neutral presentation.
For people using this wirelessly on Android, I suggest looking at the Wavelet app. It applies AutoEQ system-wide, with no need to root. This comes free. In app purchase is there more as a token of support to the dev, since it unlocks effects of little use for people looking for quality reproduction. I bought it to support the dev.
I use it with the Flat setting, although I have to say that the confusion arising between Flat, Default and Warm settings with subsequent firmware updates is beneath what I would expect from a company with Audeze's lineage.
Keep us informed clearly on what you are doing and what the settings do. It's one thing to use "young and sassy" language on the user manual but, at least for audio enthusiasts, speak clearly to us. Pretty please.
It's the single thing that annoys me the most with this product, the unknown quantities.
RTings measurements I believe were for the Default preset, at least their Test Settings state such, and likely measured pre v5 firmware. I think though v5 Flat is more similar to pre-v5 Default? If so then its for Flat, if not then Default. I think 3D mode was off as well for the measurements, though this EQ works either way
EDIT:
For expanded use of a Harman target curve EQ for the Mobius, I'm adding generated Parametric EQ and Fixed Band (standard 10 levers) versions, as well as the AutoEQ command line I used to generate it. Should be accurate, only way to get it more accurate is for oratory1990 to measure it in Hi Res mode on Flat v5. If your just after the EQ for EqualizerAPO, use the Graphical EQ settings. Parametric is usable in Roon, USB Audio Player (Android) and more, while Fixed Band is your more generic equalizer.

Optional diffuse-field addon, add this in EAPO to give the Mobius more of a diffuse-field response in the high treble, doesn't effect anything else. Could theoretically help spatial awareness and 3D mode. Definitely brighter with this, but also more 'wide' like theres a center channel, its hard to quantify. Worth testing AB.

Note, this is only 1/3rd of a full diffuse field correction. Can apply it multiple times or 3x each value to get the full effect.
Optional LFE/Sub high pass filter for DTS-HD/Dolby TrueHD, most home theater amplifiers do this. Sometimes mixing rooms have their subwoofers high-passed and dont notice high-frequency noise/garbage they leave in the LFE channel. The Dark Knight is a good example of this. This removes it all, leaving only bass in the LFE and only on 7.1 tracks. Add onto above, make sure its the last addon

EDIT:
Found that installing EqualizerAPO as a LFX/GFX on Windows 10 caused distortion, notably around 7900Hz, installing as an SFX/EFX fixed it, sounds clean. Setting is in Troubleshooting options in the Configurator. Likely something internal with where the APO is placed in the Windows Audio stack, as SFX/MFX/EFX are full replacements for Vista-era LFX/GFX. Also, post-mix uses the EFX mode, which will disable all APO's but Equalizer APO. Pre-mix is broken for me so I just unticked it in the Configurator to only have the post-mix EFX APO installed.
EDIT:
I am content. Flat + EQ + all addons (incl semi diffuse-field), 3D Auto 7.1 with Room Reflections at 30, head settings inputted, watching Avatar and Godzilla, surreal. Best headphone cinema experience I've ever had, beats any prior surround solution or headphone. Halo 1 Anniversary on PC sounds amazing, crisp and clear with a great soundfield. Bannerlord as well, locality is spot on.
Note, when doing cross-comparison, replace your whole config.txt for volume matching with

Stage: post-mix
Preamp: -6 dB
EDIT:
Personally settled on Warmest EQ, updated all EQ with Fixed, Parametric and Graphical versions of each one using AutoEQ, much more precise and performant too. New EQ's also have a more accurate replication of default high-treble for better use with standard Mobius EQ's.
No, you need to set pre-amp if using Parametric EQ or Fixed Band EQ. The graphical EQ is made of (from memory) 127 different bands which already have pre-amp applied to avoid clipping.
It's possible to use plain EqualizerAPO and edit configuration file in C:\Program Files\EqualizerAPO\config\config.txt. Replace contents of the file with the GraphicEQ.txt file found in results. Preamp is not needed because it is incorporated into the GraphicEQ line.
If you want to use Peace, you're probably better off importing the parametric EQ file. In that case you need to apply pre-amp. And every headphone model clearly displays the pre-amp needed, according to the number of parametric bands you can use (5 or 10).
No preamp needed for Graphical or Convolution, its baked in. Added that info to the post just in case.
Also, just uploaded Convolution EQ variants of all the base EQ's generated through AutoEQ. Good for use in Roon, or in EAPO. Not sure if its better than Graphical, probably more precise since it replicates the result graphs 1:1. Also minimum phase instead of linear phase, again not sure if thats better. At least its there.
Note that for the Mobius for Convolution, you would want both the 48k and 96k activated. The 48k version wont do anything until you move to 3D mode, then it would apply. 96k will activate in Hi Res mode. Same for any apps, if your using Hi Res mode in them then use the 96khz version.
EDIT:
Likely the final update, reworked all upper treble shaping to better use AutoEQ features, result is cleaner and precise. Includes more Harman tuning between 6 and ~8KHz for all profiles. Also partially reverted Harman shaping of 3KHz to account for the F5 firmware update. Lastly a very slight bass boost, better keeps the default Audeze bass levels while keeping Harman shaping. All settings updated on the first post of the last page.

To clarify: the convolution wav attachments in previous page's post have all the modifications baked in? Diffused highs as well? Could you be so kind as to summarize in a new post what your settings actually do? I'd be really grateful.
Also, since Audeze is reading this thread: could you please clarify once and for all what happened to Flat and Default eq profiles between different firmware updates? Trying to EQ these with no knowledge of the starting point is a futile endeavour. As the owner of both Mobius and Hyper-X, I'd appreciate it.
I've measured and published the differences between firmware version's EQ presets here several times.
In short:
There was only one change, when switching to FW5.
Flat and Default are the same within less than 1/2dB now, only Flat is louder 1dB, so when switching, one thinks they're different.
EQ preset slot wasted!
Flat/Default of today is close to what Music was before (green, orange line).
Mobius in general got more bass with the newer firmware (blue line).
FW5 fixed the L/R channel difference in frequency response that was a result of different acoustic properties of left and right cup.
But not for: Footsteps, Ballistics, Racing, RPG.
Here's the new FW5 "Flat", "Default" and "Music" relative to the old "Music" preset.
Thank you for this. Problem is I read that AutoEQ bases its parameters on the old Flat (or Default?) frequency response. So I don't know whether the settings are correct on newer firmware or not. Maybe @FireFreak111 could shed some light on this, since he seems to be quite knowledgeable on the subject.
Right @gorman my understanding was that apart from the general treble reduction in the firmware, there was also a slight reduction between 3 and 4KHz (which was the change I made, 1dB less reduction from the Harman curve (so 1dB more 3.5KHz treble)), wonder if I read those prior graphs wrong though.
The main thing @KaiSc I'm trying to deduce is the absolute difference between original Default, and F5 Flat/Default. Would it be wrong to assume that if the shift is the same for all presets, and that a flat line at 0dB is the original Music preset, the difference between original Music and F5 Music is the same difference between original Default and F5 Flat/Default?
EDIT:
Example using the relative difference between music presets from the above on neutral (third attempt):
Before (includes the 3.5Hz 1dB bump which is only around a ~0.25dB bump post-adjustment:

Firmware 5 changed all music related presets by the same amount:
Default, Flat, Music, Warm.
The blue curve shows the changes, from FW-old to FW-5, in summation of the left+right channel.
More bass in FW5.
Changes left and right are quite different, as AUDEZE corrected the former existing difference between both.
Therefore, looking at just left OR right does lead to nowhere.
Whatever you try, use the blue curve above as reference.
Here's the measurement of AUDEZE Mobius Flat EQ preset L+R sum, changes in Firmware 5 relative to FW 1.
These are acoustic measurements over a span of about 10 month of usage, so the earpads are not like new anymore for the 2nd measurement.
Allow for an uncertainty of ~ +/- 0.5dB.
The little notch at 5kHz is typical for pad changes on the Bruel&Kjaer Artificial Ear 4153.
With real pinnae the effect of more compressed pads is less.
Firmware 5 changed all music related presets by the same amount:
Default, Flat, Music, Warm.
The blue curve shows the changes, from FW-old to FW-5, in summation of the left+right channel.

Ignoring high frequency, roughly maps to an inverse of the relative change. Bass changes definitely are the most interesting part, the net result is that if you apply ~1:1 mapping from ~22-80Hz, a Harman bass response results in net gain from 0-22Hz and a reduction from 80-190Hz. Not sure which I prefer atm.
Also yeah I tried understanding the left/right changes but its clearly tuned very specifically to this headphone's design. L+R is much clearer to understand.
