Focal Bathys Dune Wireless Headphones

These Focal Bathys headphones deliver high-fidelity sound in a portable wireless design. They use 40mm aluminum-magnesium M-shaped dome drivers with proprietary Focal technology. Active noise cancellation blocks ambient sound during Bluetooth listening. A built-in DAC and amplifier enable high-resolution wired audio up to 24-bit and 192 kHz via USB-C.

Ideal for audiophiles wanting wireless freedom

The bundle includes a desktop stand and a 25-foot extension cable for flexible desktop use. Hands-free calls benefit from Qualcomm Clear Voice Capture technology. Both wired modes require battery power to operate the active amplification. Buyers needing passive analog operation without battery drain should consider other models.

Battery life ranges from 30 to 40 hours depending

Bluetooth with ANC provides up to 30 hours of listening time. Using the 3.5mm analog input extends this to 35 hours. USB-C wired mode offers the longest runtime at up to 40 hours. High-resolution 24-bit/192 kHz playback is supported only in USB-C wired mode.

Questions about this item

What source device do I need to use the USB-C wired mode with 24-bit 192 kHz audio?

A laptop or smartphone with a USB-C port that supports USB audio output. The included USB-C cable connects the Bathys to that device for high-resolution wired playback.

Can I connect the headphones to an older device that only has a 3.5 mm headphone jack?

Yes. The Bathys has a standard 3.5 mm input. Use the included 3.5 mm audio cable to connect to older wired sources. Battery power is still required for amplification in this mode.

How do I confirm the built-in DAC is active when using the USB-C cable?

When the USB-C cable is connected to a compatible source, the Bathys switches to wired DAC mode and supports 24-bit 192 kHz playback. The headphones must be powered on, as battery is needed for amplification in all wired modes.
