Focal Bathys MG: a wireless headphone enhanced by magnesium

Focal unveils Bathys MG, a Bluetooth headset equipped with active noise cancellation and designed to deliver faithful, precise sound reproduction. This model is built around drivers developed by the French brand, renowned for its acoustic expertise. Combining exclusive technologies, optimized electronics, and meticulous design, it aims to accompany users in their everyday listening, on the move as well as at home.

A refined, ergonomic design inspired by Focal’s craftsmanship

The Bathys MG sports an elegant design reminiscent of Focal’s high‑end wired models, showcasing the brand’s acoustic know‑how. Its headband in genuine leather and microfiber ensures optimal comfort, while the use of magnesium for the yoke and aluminum for the main structure guarantees robustness and lightness. The earcups feature the backlit Focal logo, adding a touch of sophistication. The use of premium materials reinforces the product’s upscale appeal.

The easily replaceable ergonomic earpads provide excellent acoustic isolation and adapt to each user’s morphology. Despite its 350‑gram weight, the Bathys MG remains comfortable for long listening sessions, though some users may find it a bit heavy after several hours. It is designed to accompany you on the go.

An audiophile “Made in France” sound signature

At the heart of the Bathys MG are 40 mm magnesium “M”‑dome drivers, manufactured in France in Focal’s workshops. Derived from Focal’s high‑end models, these transducers deliver natural, precise sound reproduction. The Bathys MG’s sound signature is characterized by impactful bass, detailed mids, and crystalline highs.

The frequency response extends from 10 Hz to 22 kHz, covering the entire audible spectrum, with total harmonic distortion below 0.2% at 1 kHz. This technical performance translates into a wide soundstage and captivating dynamics, making the Bathys MG one of the best‑performing wireless headphones in acoustic terms.

Connectivity and versatility for total listening freedom

The Bathys MG stands out for its versatile connectivity. It uses Bluetooth 5.2 with multipoint support, allowing you to connect two devices simultaneously. Pairing is simple and fast. Supported audio codecs include SBC, AAC, aptX, and aptX Adaptive, ensuring optimal compatibility with a wide range of devices.

The distinctive feature of the Bathys MG lies in its USB‑DAC mode, which allows high‑resolution audio playback up to 24‑bit / 192 kHz when connected to a compatible computer or smartphone. This mode bypasses the source device’s audio processing, delivering superior sound quality.

For purists, the headphone can also be used in wired analog mode via its 3.5 mm jack input. It is worth noting that even in this mode, the Bathys MG applies slight equalization to maintain its characteristic sound signature.

Noise reduction and smart features for a personalized immersion

The Bathys MG’s active noise‑cancelling (ANC) system uses eight microphones to analyze and neutralize ambient noise. While effective, it does not quite rival the very best on the market in terms of sheer efficiency. However, Focal has prioritized a balance between isolation and preservation of sound quality.

Three modes are available: “Silence” for maximum reduction, “Soft” for moderate attenuation, and “Transparency” to remain aware of your surroundings. The headphones are easily controlled via the Focal & Naim app, compatible with iOS and Android.

The app lets you tailor the sound to your liking using the equalizer (preset or custom settings), adjust it depending on your listening environment, and manage noise reduction with the Silent, Soft, or Transparent modes. It also offers a hearing test to adapt sound reproduction to each user.

Battery life and charging for extended, hassle‑free listening

Battery life is one of the Bathys MG’s strong points. It delivers 30 hours of battery life in wireless use, 35 hours in Jack mode, and 42 hours in USB‑DAC mode. Its fast‑charging function provides an additional 5 hours of listening in just 15 minutes.

This energy performance places the Bathys MG among the leaders in its category, ensuring extended use without the constraint of frequent recharging.
