This has not been mentioned much so I thought :-
"A quick guide to adjustments that works perfectly for me in making the Abyss sound sensational"
The Abyss needs to be adjusted as if you were placing a pair of speakers in a room. As Dave Wilson say, " an inch here or there will make all the difference". With the Abyss a few mm here or there, is all it takes.
- attach the ear cups with the stitching pointing straight ahead, or at 90 degrees
- with the Abyss on, one needs to adjust the bass performance and to do this, pull the drivers away from your ears and you should notice the bass increasing. Adjust the headband outwards.
- repeat the above until you will get to a point where you are at the fine line of, the Abyss having near perfect bass or sounding diffused
- with the bass dialed in, It is time to adjust the tonal balance. This basically requires the rotation of the ear cups. I will refer to the stitching, moving it upwards increases the highs and downwards the bass. It is a matter of adjusting the cups for personal preference, and allowing for upstream components.
Once dialed in, for me, the Abyss is by far my favorite pair of Headphones......................
