ABSTRACT:
This invention is a hat specially configured to carry earphones and a music player equipped with or without an attachment clip. The hat comprises slit-like button-hole openings and grooves in the bill into which the music player clip can be attached, as well as elastic retaining straps to affix the music player and the earphones. Button holes on the hat's surface form together with the headband a conduit that allow the passage, from outside to the inside, of the electrical cables connecting the music player to the earphones. The seam between the headband and the hat is open above the ears of the wearer to allow the retrieval or stowing away of the earphones. The invention also covers a method of listening to music at the option of the user without obstructing surrounding sound by keeping the earphones stowed away in the retaining area formed by the headband.
