Our Verdict
Focal Celestee
Focal Bathys Wireless
If you care about sound, the Focal Celestee are worth checking out over the Focal Bathys Wireless. The Celestee are wired headphones that are better built and more comfortable. They're more prone to inconsistencies in audio delivery, though, and they deliver less bass than the Bathys. However, the Bathys are worth considering if you're looking for something for casual use. They're wireless headphones with a USB-DAC mode to raise the volume of your audio. They have a mic and a companion app so that you can adjust their sound to your liking, and they have ANC to block out ambient noise around you.
