This is a quality of life update for the O2 headphone. Recommended for early production units (Q1 2022 - Q2 2023).

  • reprinted shells with a smaller baffle for an ergonomic profile more similar to the Ada
  • our suspension strap
  • a new cut of the E+ pad for the smaller baffle size to improve comfort and pad longevity
  • stealth wiring + screws
  • a flexible, high-airflow dust cover that mounts to the back of the driver
  • a new non-magnetic front grill
  • a renewed warranty
