Bathys is the first set of wireless headphones with active noise cancelling and high-fidelity sound! Created with the technology from the best Focal headphones, its speaker drivers with Aluminium-Magnesium ‘M’-shaped dome, made in France, deliver detailed, precise and dynamic sound reproduction. Thanks to its battery life of over 30 hours and its active noise cancelling, Bathys plunges listeners into deep silence to optimise their listening experiences. Its design follows in the footsteps of Focal’s high-end headphones. Combined with refined materials, such as Magnesium on the yokes, real leather on the headband or Aluminium for a robust construction, this results in an unrivalled comfort for any head shape.
