Oh, did I forget to mention that the Mobius can run double duty as either a wired or wireless headset? There is a lot of tech packed into the Audeze Mobius headset, and the functionality is impressive, to say the least. The term "Bluetooth"" is often treated as a 4-letter word in the audiophile community. The "B" word has the connotation of inferiority since there is a quality loss in the form of compression when transmitting audio wirelessly. From an audio quality perspective, a wired headphone will always sound infinitely better than a wireless one.
However, Audeze has implemented SBC, AAC and LDAC codecs for the Mobius. SBC (low-complexity subband) and AAC (advanced audio codec Apple and Youtube) are common in a lot of wireless devices. Audeze claims that the Mobius features Bluetooth functionality with almost three times the data bandwidth as other Bluetooth headphones. This statement comes from the fact that it implements the newer LDAC codec from Sony. LDAC can supposedly stream audio at up to 990 Kbps at 24 bits/96 kHz. Sony claims that LDAC is even closer to lossless audio due to its higher bitrate, audio sampling, and definition.
Now if the Mobius actually delivers on Sony's claim, that would be a different story. Perceptively, I did think the Mobius sounded clearer and more dynamic than some other major Bluetooth headphone competitors on the market. SoundGuys.com did an interesting test on LDAC codecs and found the 990Kbps version reaches all the way to 48 kHz, however, its resolution and noise floor is nowhere near 24-bits and are worse than 16-bits above 15 kHz. Technically by these numbers, LDAC codecs do not transmit true high-resolution audio. Now whether or not you'll be able to tell the difference is another story entirely. It does sound distinguishably better than any other Bluetooth headphone competitor out there.
The Audeze Mobius also has the ability to connect via USB-C and Auxiliary. Unfortunately, due to the amount of technology packed into these headphones, USB-C is the only method where the headphones can transmit audio passively. This means you'll have to use the battery on the device when using the Aux or Bluetooth options. I was getting about 10 hours of battery life on Bluetooth. I think that's perfectly reasonable for a wireless gamingheadphone these days. Again, being packed with so much tech, planar magnetic drivers, a detachable boom microphone, the battery life will get you through a couple of long gaming sessions without having to charge. I wasn't complaining.
