An exceptional sound, even more optimised
The Bathys MG pushes the boundaries of wireless sound excellence. "MG" refers to its exclusive Focal magnesium drivers. Their promise? Pure, ultra-precise high-fidelity sound. Its refined design, comfort and optimised electronics add to the heart of this portable headphone, which is ready to deliver incomparable listening experiences on all your journeys.
With its innovative magnesium drivers made in France in Focal's workshops, the Bathys MG delivers high-fidelity sound of remarkable purity. The bass is impactful and the highs are crystal-clear. Sophisticated microphones optimise active noise cancellation, for better voice isolation and perfect control of the environment. The USB-DAC mode offers high-resolution sound up to 24 bits/192 kHz.
Portable listening and long battery life
Efficiency in every respect. The Focal Bathys MG portable headphone integrates Bluetooth 5.2 technology and connects effortlessly. It can be easily controlled from our Focal & Naim app. It lets you adjust the sound according to your hearing sensitivity and listening preferences, and tailor it to your environment through three noise-cancellation modes: Silent, Soft or Transparent. In wired mode, this headphone allows for up to 35 hours of listening.
A premium design and such comfortable wear
The Bathys MG is part of Focal's range of premium headphones. Just like the Bathys, it features a highly refined aesthetic. It comes with a warm Chestnut finish, inspired by Clear MG, and the backlit Focal logo (if desired).
