碩士 === 國立臺北科技大學 === 創新設計研究所 === 95 === This thesis applies Kano’s model of two-dimension quality to an inquiry of the consumers’ perceptions on headphone quality. Firstly, the results of the questionnaires based on“Kano’s Paired Question”reveal that the customers’ satisfaction on the headphone quality can be evaluated in terms of five factors. The findings from the statistics analysis include that there exist ten items of ”one dimension quality”, three items of “attractive quality” and one item of “must-be quality”. In the calculation of Matzler and Hinterhuber’s quality index (the improvement and curtailing coefficient), the primary improvement index in the aspect of “appearance” is the volume and weight of headphones, “usage” the ear-pad’s cladding, “sound quality” the audibility. In the aspect of “value-added function”, it is the position of amplifier controller, and in “storage and packing” the enclosed guarantee card (sticker). In addition, that various users have different opinions on quality attributions of headphone due to the structure of different population backgrounds. In “appearance”, females show more care on “satisfactory-unsatisfactory index” of the product attribution “design and display” than males. As displayed in the index comparison chart of “usage”, males show more care on satisfactory-unsatisfactory index of the product attribution “play the music directly” than females. In “sound quality”, the improvement on the element of “bass and neutral tone” is attractive to males of 21~30 years of ages. As depicted in the index comparison chart of “value-added function”, males of 31~40 years of ages have no interest in “retractable cable”. In “storage and packing”, the attribution, “to be desk-top decoration”, is relatively attractive to females of 31~40 years of ages. Finally, a radar chart of newly developed products is drawn by means of the attribution analysis obtained from the questionnaire and literature. It provides a simple method in which the design and development strategies of the top three leading brands are analyzed and ranked.
