Focal Bathys Dune: the wireless headphones with active noise cancellation
Bathys is much more than just a wireless headset. It embodies Focal’s excellence in audio technology. Its French-made Aluminum/Magnesium “M”-dome drivers deliver unmatched sound quality. You can expect detailed, precise, and dynamic reproduction with every listen.
Bathys’ active noise cancellation immerses you in deep silence, allowing you to fully dive into your music, movies, or phone calls. With over 30 hours of battery life, these headphones are ready to follow you wherever you go.
Premium design for unparalleled comfort
Bathys’ design is inspired by Focal’s high-end headphones, evident at first glance. Premium materials such as Magnesium for the yokes, genuine leather for the headband, and Aluminum for a robust build are used to ensure unparalleled comfort, regardless of your head shape. The light weight, compactness, and perfect fit make it an ideal travel companion.
Sound personalization
Focal has added an innovative new feature to Bathys: the Mimi hearing test. Thanks to the Focal & Naim app, you can tailor the headphones’ sound to your hearing. Bathys thus adapts to your unique hearing to offer a personalized audio experience. Whatever your test results, you can fully enjoy the Focal sound.

What the press says
Focal does not intend to target mere technophiles, but rather an audience interested in a premium, even luxurious product. The construction is thus most impressive. The structure is made of aluminum, the yokes of magnesium. The headband is covered with leather on top and microfiber underneath.

Focal ne compte pas s'adresser aux simples technophiles, mais à une cible intéressée par un produit premium, voire luxueux. La construction est ainsi des plus impressionnantes. La structure est en aluminium, les branches (yoke) en magnésium. L'arceau est recouvert de cuir sur le dessus et de microfibre en dessous.
Although it leaves us with a very good overall impression, driven by its sound performance, the Focal Bathys will fully satisfy a specific audience that is primarily looking for a great listening experience, even if it means sacrificing some features.

Here’s my take after several months of use. The smartphone app is easy to use and seems to work well. The battery holds a charge well, giving us great runtime. On the sound side, nothing’s been overlooked—superb, well-detailed audio. The big downside is the comfort of the ear pads, or at least their not-so-large size. I can fit my ears inside, but at the expense of comfort.

Voici mon avis après plusieurs mois d'utilisation.
L’application sur le smartphone est facile a utiliser et semble bien fonctionner.
La batterie tient bien la charge, ce qui nous fait une belle autonomie.
Coté son, rien n'est délaissé, un superbe son bien détaillé.
Le gros point négatif est le confort des coussinets ou du moins la taille qui n'est pas grande. Je peux y rentrer mes oreilles au détriment du confort.

By way of comparison with a nearly 40-year-old wired HD 540 Reference, this wireless model is exceptional in terms of perceived "liveliness": the bass is impressive, the rest of the spectrum is well layered—maybe a tad less "airy" than the 540, if that—but there's more body. The built-in DAC is a plus; Bluetooth is excellent as well. There's no listening fatigue despite it being a closed-back headphone. In short, this headphone is a little gem. Bravo.

A titre de comparaison avec un filaire HD 540 Référence de presque 40 ans, ce sans fil est exceptionnel en terme de "vie" ressentie, les basses sont impressionnantes, le reste du spectre bien étagé, peut être un poil moins "aéré" que le 540, et encore, mais il y a plus de matière. Le dac interne apporte un plus, cependant le Bluetooth reste excellent. Il y n'y a aucune fatigue ressentie du fait que cela soit un casque fermé. Bref, c'est un petit bijou ce casque. Bravo.

Attention for big heads. It helps a bit. Otherwise, pure happiness.
