You can purchase a standalone Online License directly from the publisher, Boom NT2 , if you bought the book second-hand without a code.

| Option | Legal? | Contains De Opmaat Audio? | |--------|--------|----------------------------| | Boom’s sample chapter (website) | Yes | 1–2 sample tracks | | Public library lending (includes access code) | Yes | Full (temporarily) | | Second-hand book with unused code | Possibly | Full if code untouched | | YouTube unofficial reading practice | No / unclear | Rarely exact; low quality |

If you bought a used book but need the audio, email Boom customer service. Explain your situation. Sometimes, they offer a discounted rate to purchase just the audio tracks (e.g., €10) rather than the full digital package.

Users on Reddit report that the digital license often expires after one year or cannot be reused if the previous owner already activated it. Without the audio, a significant portion of the book's content (listening exercises) becomes unusable.
