[6] It was directed by Juanjo Giménez, who also wrote the screenplay alongside Pere Altimira.

[10] Reviewing for El Periódico de Catalunya, Beatriz Martínez gave Out of Sync 4 out of 5 stars, considering the film to be "an allegory of the loss of links with reality when everything around us crumbles", labelling the number of (different) layers in the film as "prodigious".

[11] Sergi Sánchez of La Razón gave it 5 out of 5 stars, extolling how "it approaches sound with an unusual aesthetic rigour, never forgetting to delve into the emotional journey of its protagonist", while warning that its risky formal proposal may put off more than one viewer.

[12] Carlos Marañón of Cinemanía gave the film 3.5 out of 5 stars, writing that the film proposes "a story underpinned by the opposition between silence and sound", in a manner as effective as it is disquieting, "which brings us back to the simplicity of pure cinema".
