What a FUN pair of headphones!
I bought these mainly for use with iPad, watching Netflix and listening Spotify/Qobuz. For hi-res 96kHz/24bit I connect the Mobius using USB-C to USB-C with my iPad Pro. Mostly I use Bluetooth for convenience and while one cannot expect the best quality, watching Netflix or YouTube is so much fun with the Mobius and I don't feel a lot of difference with the hi-res. For music I prefer to be in hi-res USB connected mode.
My preferred EQ setting is 'default' - this is supposed to be the Audeze sound. 3D mode I prefer off, although it creates a wider stage and make the world around you seem bigger, the more intimate sound feels more real, especially for voices during dialog. Even in 3D mode of, action scenes with explosions sound like I never heard before: deep trembling bass but very fast and detailed, not muddy at all with a lot of richness and detail, but not too sharp to make my ears bleed.
I'm not an audiophile, but I do love headphones. I own Dan Clark AEON 2 Closed, Quad ERA-1, Sennheiser 660s, Fidelio X2HR. With Bluetooth support I have Beyerdynamic Amiron Wireless, Sony WH1000-XM2, Sony XB950BT. For conference calls and my too little gaming time, I use a Beyerdynamic MMX300. My DAC/AMP for wired desktop listening is an Audio-gd NFB-11.38. For wired iPad/phone I use a DragonFly Cobalt and for wireless Bluetooth I use the Fiio Q5s with wired headphones.
I'm really amazed how the Mobius can stand its own between my other headphones. It is more fun than the Amiron Wireless for mobile listening, I like it more than the wired Dan Clark for desktop listening and mobile using Fiio Q5s, and would put it on par with the Quad ERA-1 for how much I'm enjoying them.
My Quads are not ideal for mobile use, they are open back and must be handled with care. I used the AEON 2 CB for mobile, and while they might be more refined compared to the Mobius, I have much more fun with the Mobius. Add to this that the Mobius supports wireless and I do not need to drag my Fiio Q5s and cable my headphones to it and the experience becomes so much more convincing.
The only little drawback they have is battery life. My other BT headphones easily last me more than a day, the Mobius requires regular recharge when used wireless. Connected to iPad for hi-res they easily outlive one day use, then I'm using a USB-C port extender that provides a USB-C charging port and a USB-C data port. I have several port extenders and as long as it has 2 USB-C with one marked explicitly for charging, it works great.
On the comfort side the clamping force is a bit tight out of the box, but not to the level it is uncomfortable. You are just reminded you have a headphone on. They are very solid and sturdy, good for travel and mobile use. They are not compact nor do they fold, so expect to need a bit more room in your backpack when traveling.
If you are on the fence to buy these, don't hesitate! Unless you need a long battery life and noise canceling for intercontinental flights (in some distant future maybe), but for home use there is nothing better imho.
