No replacement parts
The headphone sounds great; this is the good part of it. The way it heats and compresses the hair while making dressing glasses nearly impossible, is the middle part. The cables are tha shame part. The architecture is great; everyone knows the weak part of an headphone are the cables, even if the Focal cables break particularly quick, and so the fact they accessorize the headphone with a detachable wire would be a wow factor. Right? Wrong! Focal has no replacement cables! The first time I contacted them for the broken cable they asked me to send the whole headphone [sic] for a replacement (the cable weight few grams). Now that it happened again I preferred to purchase a Chinese cable for $6 that still feels out of tune with the headphone, but at least works, and perhaps shall last longer.
Pros: Great sound and noise reduction. Fine materials, from the exterior.
Cons: The cables break after few months of use often due to the detachment of some internal wire disabling stereo or making sound intermittent. Yet they are welded in the "beatiful" cable and so unopenable and Focal sells no replacement cable! The second cable has no microphone and so the only way out is purhasing a third party cable.
