"We completely understand that not everyone can go out and spend this kind of money on a pair of wireless headphones."
"But, we would implore you to take the time to listen to the Focal Bathys Mg. The original Bathys showed Focal could make the jump from wired to wireless successfully, and the changes made for this version push the envelope even further. They’re exceptional performers."
"Could Be Seen as a Relative Bargain"

"Should Be Considered a Measuring Stick aor Other Brands"
"The Focal Bathys MG should be considered a measuring stick for other brands to be competitive in the high end landscape. Whether we’re talking about sound quality, ANC performance, comfort, design or features, they all can and should do better," notes Andrew Park, headphones.com, April, 2025.
"The Focal Bathys MG brings subtle yet important upgrades that favor refinement over flair. With a smoother treble, tighter bass, and a wider, more balanced soundstage, the MG delivers a more polished experience—especially when used in wired DAC mode. While it may not be a night-and-day transformation, audiophiles and detail-obsessed listeners will likely hear and appreciate the differences. If you value clarity, realism, and a more relaxed tonal balance—and can justify the cost—the Bathys MG is the better long-term investment," reports Delaney Czernikowski, audio46.com, June 6, 2025.
App Control Features Sonic Tailoring
Providing efficiency in every detail, Bathys MG is equipped with Bluetooth 5.2 technology for seamless connectivity. Control is simple via the Focal & Naim app, allowing you to tailor the sound to your hearing and listening preferences.

The headphones are compatible with the voice assistants on your devices. To activate this feature, press the button on the right-hand earcup of the headphones and speak.
Extended Battery Life
These excellence wireless headphones offer 30 hours of battery life in Bluetooth® mode, 35 hours via Jack, and 42 hours in USB-DAC mode (cables included). Fast charging adds 5 hours of listening time in just 15 minutes.
Connect to Several Devices at the Same Time
Bathys MG headphones are fitted with multipoint Bluetooth technology, which allows them to be connected to two devices at the same time. The headphones can therefore switch easily between two audio sources without using the normal process of Bluetooth, reconnection. They can also automatically answer a call on your phone when you are listening to audio content on another source (for example, a computer or tablet).
These headphones can save up to eight devices. If more than eight different devices are connected, the device that was paired first will be removed. You will need to pair it again. To do this, press and hold the multifunction button for four seconds.
"Raises the Bar for Wireless"
"The Focal Bathys MG are excellent sounding wireless headphones, it raises the bar for wireless. The non-MG Bathys have a studio quality presentation holding back a bit of the realism, and the Focal Bathys MG have that live and in person presentation," observes reviewer Durwood, audioreviews.org, June 17, 2025.
"Just as with their other models, the Bathys MG is absent of creaking and weird noises, while still combining plastic, metal and soft genuine leather. It is the extra details making them feel well put together that ensures a premium experience."
