“How can we pursue Innovation in the Classics?” This is a question that David’s Formula never stops asking itself when it is designing ear-bud earphones. Before its elite team begins the design process, David's Formula researches preferences of different consumer groups, running cross-analyses with market trends. In so doing, it addresses the needs of more finely delineated consumer groups and is able to predict future design trends. Then the product design team works through a “five senses marketing” concept. It is also worth mentioning some of our latest design breakthroughs: decorative trimmings with shark fins or butterfly dance, which gives the external shell a 3D layered look and displays an unprecedented sense of fun. Also available are special models that combine different types of materials, introducing silicon extensions into earphone shells,creating a brand new textural and visual experience for users.
