This right here is the real deal - I held off to write the review until I got the 770 Pro 80Ohm headphones and here it is:
Regarding the sound, there is a CLEAR difference when plugging into the audio interface and when plugging into whatever soundcard you might have. Also, it drives 80 Ohm headphones without any issues, to get really satisfactory volume (a bit loud) seems to be at 60% of the volume dial (keep in mind, this is without any headphone amps) - at 100% it is blazing and too loud.
As I am a guitar player, I bought this audio interface exclusively because it had the "Pad" option, and having a guitar with Active pickups (EMGs), I didn't want to invest in an additional DI box etc - the "padding" does wonders and there is no clipping/distortion caused with the feature turned on. If you have a guitar with active pickups (especially hot ones like EMGs), I really recommend this audio interface.
I also use the t.bone M85 Beta microphone for either some "riff idea" recording or simply using the microphone during gaming. There have been many times where I was deliberately close to the microphone and was speaking in an... ASMRish voice and everyone in the Discord or game voice chat went "DUDE WTF" - the signal is clear and there is no clipping (once you play a bit with the knob).
Honestly, I cannot imagine NOT having an audio interface going forward and this little red thing spoiled me.
