Received the Dekoni Stellia earpads yesterday for the Focal Clear.
They even out the midrange, increase the low end, and add some air and sizzle to the top end.
All this without sacrificing the driver's speed and dynamics, thanks to the diffusion fabric that mimics the stock earpad. I have been thinking that the 3rd party Focal earpads will have to do this to be taken seriously and I have been proven right.
All the detail is there, but the bass is bumpin', vocals are full bodied, soundstage is a little bigger also. The 1.5-2khz area is the one place it takes a hit; vocals take a backseat but the quality of the vocals is more coherent, to my ears.
These are better than Utopia earpads on the Focal Clear (and I have a pair!). They are also miles better than the Dekoni Fenestrated earpads.
The material quality is also really good... super soft leather. Worth while to give it a good condition before use to make sure they will last the long haul!
