In an effort to give digital peripheral products the familiar feel associated with analog products and sophisticated humor that makes users happy, this product was developed focusing on the value created by design, rather than on price or specifications. The name “Otokurage” was combined from two Japanese words meaning “sound” and “jellyfish”. The product’s design focuses on earpieces, not usually considered a part of headphone design. By designing with earpieces in mind, these headphones mimic flowing jellyfish. For better in-ear fit, four sizes of earpieces are available. By changing earpieces, users can enjoy the delicate changes in design.
