Elex pads - Clear Pro pads - Utopia pads
Elex and Clear Pro pads. No matter how much you wash them they just get dirty.
Clear Pro and Utopia pads.
I had to get a shot of the Clear Pro pads on the Elex. They look like burgundy in real life.
So, they pretty much all have the same frequency response. They sound almost identical.
Clear Pro must have a little more top-end zing in things I was listening to (snare drum ringing)
However, I brought out the replacement Elex pads that drop.com was shilling recently. If you don't know, they recently refunded all orders as the pads Focal had sent were up to 15% lighter than the stock Elex pads. They skimped a little, on the foam perhaps, as a result of strikes in France and difficulty with material supply chain and/or labor costs. Drop customers were less than thrilled with the whole ordeal, as you might imagine.
Here is the Elex pad at the bottom, the replacement Elex pad in the middle, and the Utopia pad at the top.
You can't tell from the photo but the Utopia and replacement Elex pads compress much more easily than the Clear Pro, and even the stock Elex pads.
As a result the Elex and Clear Pro pads have a more roomy presentation, and the Utopia feels slightly more 'in-your-face'.
If I had to recommend I would advise you
don't buy the Utopia pads, unless you don't mind that trade-off (it's not a huge difference), or want them purely for comfort (they are so damn comfortable. The thicker pads start clamping my head). Maybe Focal will go back to the original material for future pads. Maybe the Utopia pads were always like this, I can't tell you if that's the case. Either way I'm sticking with the Utopia pads... Focal aren't the best for huge soundstage anyway
