Audeze Mobius review / impressions

i am looking for a headphone with which i can reproduce 5.1, 7.1 and dolby atmos through the 6.25 mm analog headphone output of my yamaha cx- a5100. anyone knows ?
If your Yamaha CX-A5100 can decode the mentioned audio formats into a 2-channel headphones surround format like DolbyHeadphones, any headphone will do.

The analog 6.25 mm connector is stereo (2-channel) only, no way to send discrete 5.1 or 7.1 audio channels through.

Mobius does simulate a virtual 7.1 setup out of an analog (or digital) stereo signal.
Mobius produces a realistic illusion of sitting in a room with a 7.1 speaker arrangement, but does not reproduce the original 7.1 mix and effects, i.e. like a sound circling around you.

For real 7.1 effects like that you need to connect Mobius to a PC via USB.

This is Mobius‘ Achilles Heal - no way to connect it to a TV set, Blue Ray player or the like for true 5.1 or 7.1 surround.
It doesn’t have a fitting interface like S/PDIF or HDMI, and it doesn’t have the decoders built in.

i don't understand very good what you mean by decoding the mentioned audio formats into a 2 channel( ?) headphones surround format. can 2 channel be a surround format ? how can i know if the cx-a 5100 can do such a decode ?

Headphones have 2 channels, left and right, that’s it.
To trick the ears and simulate more channels WavesNX, DolbyHeadphones or the like are used.


Surround sound for speakers is packed into different “Codecs”, like Dolby Digital, Dolby Atmos, DTS ...

A quick glance on the Yamaha site showed, your AV Receiver can “decode” these into discrete separate audio channels for loudspeakers, like left, center, right, ... up to 11.2.

But - I couldn’t find any hint that the A5100 can repack those channels into DolbyHeadphones or any other 2-channel format that is suitable for a normal headphones.

Guess you’re stuck with plain stereo - finally not too bad, as true surround on headphones doesn’t work too good on most - except on Mobius!

It can’t do that. Dolby atmos will always send the decoded sound from the tv. Soundblasters turn codec into SDX but I you might wanna disable atmos in that case. And again what you will receive is VSS on 2 stereo channel with Mobius or just use 2 channels with 3D on Dolby etc off. I’m hoping for a new version of Mobius that connects with the Xbox and PS systems on 7.1 channel. Not something like Penrose because it’s a few steps down from Mobius with lacking 3D properties. Yet as mentioned above unfortunately very sadly there are only theories about how to get 7.1 channel on Mobius only myths nothing else. Believe me I spent weeks to find a work around but no luck. Somehow they should fix this. If analog connection doesn’t work give me a USB extension which will work with these next gen consoles or give me a new headset like Mobius. 🤷🏻‍♂️

PS: http://www.sonore.us/ultraRendu.html

this is the device I found that might work with Mobius on 7.1 channel. I would reallly love to see a review of these and how they deliver the sound from Ethernet cable. Anyway. Here you go!

Sonore ultraRendu might likely play sound on Mobius, but how would I get the sound from my TV Set into it?
Even if the TV could stream via network (mine can‘t) - Sonore ultraRendu doesn‘t decode any surround format, at least no mention of Dolby Atmos and the like.
They might have skipped surround decoders because they cost a license fee.

In order to get surround with headtracking similar to Modius requires a computer outputting your surround sound files (movies or music) via USB or S/PDIF to the Yamaha receiver. You will need to run surround processing software on the computer to convert the 6-8 channel audio to 2 channel. A headtracking device mounted on the headphone and communicating with the computer will give the same effect as the Modius. There are several cheap systems for this application: NX Head Tracker for Headphones (requires NX Mixroom software) or Redscape Headtracker and Software.

That´s true, but if a computer is already involved, the simple and best sounding solution is named “Mobius”😂
Unless one likes to spend $1K+ to get better headphones.

i don't understand how this Could be a solution to my problem. unless if you mean to spend more than 1000 dollars to a headphone ? will i have then dolby atmos, surround 5.1 7.1 or so ouT of which headphone ? I DEFINITELY USE NO COMPUTER TO LISTEN TO A HEADPHONE.

This in fact IS what I meant: no computer - no true multichannel surround - sorry!
Not out of an AV-amp or a TV-set, unfortunately.

With computer, Mobius is the BEST solution for immersive, true multichannel, surround / 3-D experience, as it has the Headtracker+WavesNX built into very good sounding headphones.

If this is not good enough (soundwise) next stop is way more expensive, and less convenient.
WavesNX+Headtracker hardware are available separately to mount on any headphones.
Again, limited to PC use only.

Or one could go the Smyth Realizer route, good luck!

This is maybe the best answer to the primary question:
Meanwhile, connecting the Mobius to the analog (6.25 mm) jack of the Yamaha, and use Mobius’ plain stereo to 3-D function, gives quite an amazing, immersive result no other headphones offers.

The NX headtracker costs $99 and the software is currently $29. It can be attached to any headphone, even a $30 pair. Redscape with software is $140 and again attaches to any headphone. So computer based alternatives to the Mobius aren't that expensive.

It was stated earlier that if you don't have headphone surround processing in your receiver or Blu-ray player/streamer, then you can't have surround out to the headphone. The Yamaha receiver CX-A5100 does not allow direct computer input, similar to outputting to a Dac. Using a computer to stream a movie/music through some headphone surround software out a GPU's HDMI into a receiver should provide the 2-channel surround audio to the headphone jack. Optionally the Modius can be connected, via USB, to play back the surround data instead of a surround processor software.

Since the Mobius requires a computer to get true 7.1, using the analog in isn't the answer to getting surround out of a receiver's headphone jack. I agree that the 2-channel surround experience with the Mobius is nice. I personally find the Mobius to be too heavy and ill fitting, not comfortable for long sessions.

How bad is the mic on these? look basically no headphone I have heard with built in mid can match like a mod mic but on the grand scale how bad is it? HyperX stuff is pretty garbage it's at least better than that right?

Need a headphone with mic for casual convos

I haven't run into any issues with the mic, and I'm definitely a casual user (just party chat with my friends). The mic works well enough for that; I come in clear and they don't hear my breathing most of the time.

Mobius mic is decent enough. It’s not like v moda boom mic good but it’s still good. I’m gonna order Penrose mic cause I heard really good recordings with it. Not that I’m not satisfied with Mobius mic but to have a better option. It’s is sold on Audeze’s website. You can check them out.

Well after like several months of usage and adjustment, I've found a way nicer EQ for the Mobius than the one I shared, basically a completely different correction still using AutoEQ, thanks to the new measurements from oratory1990 which work way better. I've settled on a EQ between my previous Warm and Warmer settings, achieved with a simpler sound signature file only reduces the 6KHz bump from the default oratory1990 Optimum Hifi curve, having adjusted said curve to preserve high-frequency detail past 10KHz.

I highly recommend Convolution with double-precision EqualizerAPO. Preserves all small adjustments to the curve, as a result music is such a joy to listen to on the Mobius, and in general it just sounds more natural to my ears when combining this curve with the imaging/detail/bass of the headset.
Link here for 64 bit processing EqualizerAPO

New EQ, using the oratory1990 Optimum HiFi curve. Use the Default Mobius preset on the latest firmware.
Convolution (Recommended):
(Add both .wav files specifically in EqualizerAPO, it will auto-switch between 48k in 7.1/Stereo, and 96k in High Res). Paste in /config folder.

Optional LFE/Sub low pass filter for DTS-HD/Dolby TrueHD, most home theater amplifiers do this. Sometimes mixing rooms have their subwoofers low-passed and don't 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 multichannel tracks. Add onto above, make sure its the last addon
Channel: SUB
Filter: ON LPQ Fc 250 Hz Q 0.75
As a note, to compare this EQ to non-EQ, overwrite your EQ'd config.txt with a -5.9db preamp, then just undo/redo for instant comparison.

Compared to my first EQ, feel like I found a distinct improvement for my own enjoyment. Thankyou AutoEQ, and thankyou oratory1990. Also @FlavioWolff ping since you commented recently about it.
