Sound Quality and Driver Technology
The Arc-1 headphones utilize 40mm dynamic biocellulose drivers combined with 24-bit DSP and Bluetooth aptX codecs. This advanced driver design ensures crystal clear, distortion-free sound across the entire frequency range, from deep bass to high treble.

The biocellulose composite speaker cone, with its flexible surround, allows for free movement and reduces breakup distortion, resulting in enhanced dynamics and cleaner sound reproduction.
