Check out this review of the Focal Clear by a professional engineer that use to be VP of Digital Media at Microsoft.
I quote
"First and second tracks sounded good and then BAM! The headphone jumped its gap resulting in nasty static/crackling sound. The kind of sound that stops your heart beating for a few seconds! Basically the driver is running out of travel and going outside of the magnetic field and then jumping back suddenly. I hear this routinely in cheap bookshelf speakers when driven by high amplification and deep bass. I could get this to happen even in instrumental/female vocal tracks!
Granted, we boosted the EQ but I have boosted EQ much more in other headphones and they can handle with ease. Not so with Focal Clear. Still, I turned off the EQ and turned up the volume and there it was again: nasty clicks. Granted the level was pretty loud now but not outside of what would be listenable.
Searching online, I see references to Clear "clipping." I suspect this is what they are talking about. If so, it is real flaw in this headphone
The Focal Clear "out of box" (no EQ) response is closer to what we like to see so tonality is not too bad as is. Equalization can take its performance significantly higher but due to poorly designed drivers with too little headroom, this is not a practical path unless you keep volumes low. Without EQ is less of a problem but you would face some brightness and some lack of clarity. At these prices we better not have such compromises.
I can't recommend the Focal Clear with or without Equalization. I expect more from a company like Focal with incredible vertical integration to build drivers and such."
