The purpose of this dataset is to analyze user experience in a virtual reality (VR) environment, focusing on a comparative study between visual and audiovisual stimuli based on the archaeological site of Edzna, Mexico. The immersive experience allowed participants to explore the site without needing to physically being there, and the experiment was conducted in a museum setting, offering a unique experience that goes beyond traditional visual-only exhibits. The dataset includes both Electroencephalography (EEG) recordings from eight channels (Fz, C3, Cz, C4, Pz, PO7, Oz, and PO8) and user responses to the User Experience Questionnaire (UEQ), providing necessary data for future studies on how immersive environments affect user perception. 
The EEG data was collected using a Unicorn Hybrid Black EEG system with a sampling rate of 250 Hz. Participants were exposed to two conditions: a visual-only stimulus and an audiovisual stimulus, both of which represented scenes from the archaeological site in VR. Prior to exposure, a baseline measurement was taken to capture the initial state of the participants. Data collection was conducted in MOSTLA, a digital innovation lab at Tecnologico de Monterrey campus, and the Museum of Contemporary Art in Monterrey.                                                                                                                                                                                                                                       
                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                            
Each EEG recording is shared in .set format and follows the BIDS structure. The recordings include eight channels of brainwave recordings for the baseline, visual, and audiovisual conditions. The signals are presented in both formats: raw and preprocessed. Additionally, an .xlsx file is provided with basic participant metadata, such as age, gender, unique identifier as well as the UEQ responses.
