Five passive Focal headphones, two acoustic approaches and three driver materials. This guide connects the specification to the place you will actually listen.
The first decision
Open-back and closed-back headphones solve different problems. Choose the acoustic format before choosing the model.
Open headphones allow air and sound to move through the earcups, supporting an expansive presentation in a quiet room—but they leak sound and offer little isolation. Closed headphones contain more sound, reduce external distraction and make more sense around other people.
Driver material, weight, impedance and the quality of the source chain then refine the shortlist. A private comparison is more useful than treating price as a ranking.
Current collection
Focal’s current high-fidelity category includes these five passive models. Bathys is positioned separately by Focal as a wireless active-noise-cancelling headphone.
A reference personal listening system in a quiet, dedicated space where openness, realism and resolution take priority over isolation.
Explore model
Reference listening where privacy and acoustic isolation matter—at home, in a shared space or during considered portable use.
Explore model
Serious at-home music listening for clients who want an expansive open-back presentation, strong dynamics and an easier step below Utopia.
Explore model
Long, relaxed listening at home when low weight, easy source matching and open-back spatial presentation are priorities.
Explore model
Everyday high-fidelity listening when you need passive isolation, a lighter enclosure and compatibility with portable sources.

Fast comparison
Specifications narrow the field. Comfort, isolation, tonal preference and source pairing still require listening.
| Model | Design | Driver material | Impedance | Weight | Frequency response |
|---|---|---|---|---|---|
| Utopia | Open-back | Pure Beryllium | 80Ω | 490g | 5Hz–23kHz |
| Stellia | Closed-back | Pure Beryllium | 35Ω | 435g | 5Hz–23kHz |
| Clear Mg | Open-back | Magnesium | 55Ω | 450g | 5Hz–23kHz |
| Hadenys | Open-back | Aluminium / Magnesium | 26Ω | 294g | 25Hz–22kHz |
| Azurys | Closed-back | Aluminium / Magnesium | 26Ω | 306g | 15Hz–22kHz |
Open-back
Utopia, Clear Mg and Hadenys are intended for listening where sound leakage will not disturb others and ambient noise will not mask fine detail.
Closed-back
Stellia and Azurys place a physical enclosure behind the driver, improving isolation and making shared-room or portable listening more practical.
Driver progression
Each 40mm driver uses Focal’s ‘M’-shaped dome geometry. Material changes the balance of stiffness, mass and damping—and therefore the engineering route to control.
Utopia and Stellia use Focal’s reference diaphragm material for extremely low moving mass and high rigidity.
Clear Mg uses a magnesium dome chosen for lightness, damping and dynamic precision.
Hadenys and Azurys combine aluminium rigidity with magnesium damping in a lighter, accessible design.
System matching
Passive headphones rely on the source, DAC and amplifier connected to them. Impedance alone does not predict sound quality or whether a device will provide enough clean voltage and current.

Frequently asked
Utopia, Clear Mg and Hadenys are open-back. They suit quiet, private spaces because they leak sound and provide little isolation.
Stellia and Azurys are closed-back. Stellia is the reference option; Azurys is lighter and intended for flexible home and portable use.
No. Focal categorises Bathys separately as a wireless headphone with active noise cancellation. This guide follows Focal’s passive high-fidelity category.
It depends on the headphone, source and listening level. Even easy-to-drive models can reveal improvements in noise, dynamics and control from a well-matched DAC and amplifier.
