Our Verdict
Focal Celestee
Focal Azurys
The Focal Celestee is a higher-tier model than the Focal Azurys, with a more premium build. They're kitted out with higher grade materials, but the metal-clad Azurys aren't poorly constructed, just cheaper to produce with fabric earpads, for example. Both closed-backs provide a little noise isolation, but not much. Both have warm frequency responses, and the Celestee exhibit slightly better frequency response consistency. Still, if you want an in-line mic and can't shell out for the higher-end model, the Azurys is worth a shout.
