To promote a new series of The Traitors, ON THE SLY worked with BBC Creative to produce an immersive 3D binaural audio trailer designed for headphone listening.

The concept places the listener at the centre of the show’s iconic round table. Using spatial audio, the trailer creates the sensation of Claudia Winkleman moving around the listener, circling the table before leaning in to whisper directly into their ear. The effect mirrors the tension and paranoia at the heart of the programme.

Through careful sound design and spatial positioning, the piece builds a short narrative moment that places the audience inside the world of the show rather than simply promoting it.

The result is a trailer that feels less like a traditional campaign execution and more like a brief immersive experience — drawing listeners directly into the psychological atmosphere of The Traitors.

This project sits alongside ON THE SLY’s wider work in immersive audio, broadcast campaigns and large-scale experiential sound design.
