Focal Hadenys
Open-back Hi-Fi headphone with 40 mm aluminium/magnesium drivers — warm, detailed, dynamic
Sound, in Detail
Developed and manufactured in France in Focal’s own workshops, the 40 mm aluminium/magnesium dome drivers deliver a pure hi-fi sound that’s detailed, warm, and dynamic. The ideal headphone for a no-compromise listening experience at home.
Comfortable & Lightweight
Thanks to the lightweight magnesium yoke, these headphones are perfectly suited for long listening sessions, while the memory-foam earpads add extra comfort.
Refined Craftsmanship
With earthy brown tones, Hadenys carries a refined, sophisticated look — a colour that feels both fashionable and timeless. Inspired by the Hadean era, the period when Earth formed around 4.6 billion years ago, Hadenys represents a return to our natural origins.

Measurements
Frequency response
What does this mean?
The line marked as target is something you could call the “ideal” curve: a target response derived from research by the Harman group, exploring what kind of headphone tuning tends to be preferred by a broad range of listeners – regardless of age or demographics. This is often referred to as the Harman Target.
From left to right you see sub-bass, bass, mids, and then the curve tilts upward where treble begins. That part of the spectrum is naturally amplified by the shape of the human ear.
These headphones are tuned for two things: fun and high detail retrieval. They’ve managed to create an open headphone that still carries a small bass lift instead of the typical big drop. You don’t see that often — and that’s exactly why these headphones are such a joy.
