Our Verdict
Focal Bathys Wireless
DALI IO-12
The Focal Bathys Wireless and the DALI IO-12 offer a comparable feature set and sound. Both headphones feature some extra emphasis in their bass range presentation, but the DALI rolls off some high-end for a darker sound, while the Focal opt for a bit of extra treble-range detail. While the DALI's sound profile can be adjusted via a singular EQ preset, the Focal offer far more customization via the graphic EQ in their companion app. When it comes to on-the-go use, the DALI's supremely comfortable fit, longer battery life, and great build quality elevate them above the Focal, and they feature a slightly better-performing mic. Still, the Focal's ANC system is more capable of cutting out external noise, and it's able to deliver audio more consistently.
