Combining Miryoku Engineering and Evaluation Grid Method Explore Wireless Headphone Design Appealing Factors

Among the many electronic products, wireless Bluetooth headset is one of the products preferred by young people in recent years, and its large sales volume makes researchers interested in the factors affecting the sales volume of the products. In this study, the evaluation grid method (EGM) in the field of Miryoku engineering can be used to standardize the user’s preferred style and corresponding design features through production image cards, expert interviews, KJ method, questionnaire surveys. After the quantitative I-category analysis of the EGM, the shape characteristics of consumers’ preferences for wireless headphones can be standardized. and it is found that consumers have a higher preference for “Streamlined Overall”, “Rounded Edges”, and “Single and bright color”, so these features can be defined as the most appealing features of wireless headphone for 18–25 years old consumers. The results of this analysis can be used as a reference for the designers to suggest the design specifications.
