Headphoneus Supremus
A quick note that Focal were wonderful (as was my local dealer) and replaced my Elear drivers under warranty, with the only cost to me being $20 in freight. This was after a low-bass clipping issue arose.As long as the person you're buying from has a receipt for the headphones from an authorized dealer you would be covered as Focal changed their policies on warranty to be transferrable.
Warranty varies per Headphone (Clear, Stellia are 3 years, Utopia is 5). I'd also double check and make sure the headphones were purchased in the same country as you. If not, they'll have to be sent to whatever country there purchased from for warranty.
I can't speak to pricing on repairs. I know headband repairs can be fairly pricey. Not sure about driver replacements.
Excellent service, and after 100 hours of (careful) break-in, the Elears sound spectacular.
