Hey everybody! I'm a long-term lurker on this thread (I was an Indiegogo backer), and I just wanted to let everyone know something weird that happened to my Mobius. I went through Audeze's support email (awesome help!), but they ended up needing to RMA my headset. I'll post what I sent them.
Basically, I woke up one day and there was no audio coming from any source, or from the built in voice that says “power on” or “7.1 channel”. I had been using firmware beta v3 for several weeks, and it had been working fantastic. I started work that day and turned on my Mobius, but, alas, no audio. I opened up the Audeze HQ app on both a Windows and Mac computer, but the app ddd not detect the Mobius as connected. The light on the Mobius responded as if it was working however. It showed the charge light and also the bluetooth connected light. I could hear the slight hiss of the amp while the headset was “on’. The Mobius even responded to button presses, ie the computers both show the Mobius switch audio modes. However, the audio modes no longer showed the updated naming conventions, so the surround sound mode showed up as 8-channel, rather than 7.1. Each connection I tried also responded to the volume scroller, so on Mac the volume changed on OS when I changed volume with the Mobius. However, no audio and no voice prompt can be heard through all the above steps.
The ONLY thing that happened was I updated my macOS to the latest version overnight and left my Mobius plugged in. I have NO idea if this just happened to line up with my headset dying on me, but I thought it might be worth warning everyone that perhaps leaving your Mobius plugged into a Mac while it updates MIGHT mess up its firmware.
Aside from this hiccup, I love the Mobius and these couple weeks without it have really been hard to adjust to haha. Also, Audeze has been extremely quick to get my issue sorted, so high marks for their service!
