The YP-F1 is an MP3 player designed to target later teens and earlier twens and it is characterized by the concept of a luxurious and casual fashion accessory. As an ultra-small music player targeting a generation that is not satisfied just by listening to music but is also very sensitive to fashion, its design is intended to highlight the motifs of various styles of wear (clip type) and to allow changing faces (replaceable front cover). Living up to the keywords “luxurious and casual”, this product visually expresses a taste for classiness and colorfulness – designed to target a young generation pursuing distinction and microminiaturization.
