FCC Filings Hint at Unreleased Apple or Beats Bluetooth Headphones

The U.S. FCC published documents for an unreleased Bluetooth over‑ear headphone with model A3577. Details are largely confidential, and it's unclear whether the device is from Apple or Beats (not AirPods Max 2, which has a different model). A Beats Studio Pro revision is a possible scenario, with more information expected as filings are reviewed.
