A reversible headwear (100), such as a beanie, includes a reversible headwear body (110) and a pom-pom (150) connected thereto. The reversible headwear body (110) is adjustable between a first configuration and a second configuration. The headwear body (110) has a first surface (112) and an opposite second surface (114). The first and second surfaces (112, 114) correspond to outer and inner surfaces respectively in the first configuration of the headwear body (110), and to the inner and outer surfaces respectively in the second configuration of the headwear body (110). The headwear body (110) has a through-hole (130) extending from the first surface (112) to the second surface (114). The pom-pom (150) is configured to be connected to the headwear body (110) to allow movement of the connected pom-pom (150) through the through-hole (130) for positioning the connected pom-pom (150) over the opening on or over the outer surface when the headwear body (110) is in the first configuration or the second configuration.

Earphone apparatus includes dry electrophysiological electrodes and, optionally, other physiological and/or environmental sensors to measure signals such as ECG from the head of a subject. Methods of use of such apparatus to provide fitness, health, or other measured or derived, estimated, or predicted metrics are also disclosed.

The HATDANA HAT simply put based on apparel industry guidelines for head sizes and hat sizes, is a more efficient and economical manufacturing process of making several hats from one same square yard of fabric. By being able to cut several two specific shapes a Rectangle (brim) and Triangle (crown) from one same square yard of fabric and stitching with one stitched seam one each of those two specific shapes together in a particular way a Rectangle and Triangle yields one hat. Being able to cut several Rectangles and Triangles from one same square yard of fabric yields several hats. Each hat covers head in entirety based on the hat making industry's own understanding of hat and head sizes.
