My review of the Focal Azurys and Hadenys is up:

Included are comparisons to the Elex and HD 600 for the Hadenys, and Bathys for the Azurys.
Overall, I think Focal did a good job with both of these headphones and they are well-worth the recommendation.
The Hadenys I was pretty meh to begin with but after sitting down and properly doing side-by-side comparisons to the Elex and HD 600, I would take it over those two if I was buying a new headphone today. My only nitpick is that I feel like it could've been priced similarly to the Azurys.
The Azurys is also excellent and I prefer its sound to the Bathys. But if you're wanting to get a headphone specifically for travel, then I think the all-in-one wireless package of the Bathys is still a superior experience.
