A pillow system configured to engage the back and sides of a subject's head, the pillow system comprising: cushioning material (45, 50, 55) configured to engage the back and sides of the subject's head responsive to the head of the subject being in place on the pillow system; a resilient frame configured to surround the back and sides of the subject's head to hold the cushioning material (45, 50, 55) in place on the subject's head, the frame comprising: - a first portion having a first inner side and a first outer side, the first portion being configured to hold the cushioning material (45, 50, 55) in place on a first side of the subject's head responsive to the subject's head being in place on the pillow system; - a second portion having a second inner side and a second outer side, the second portion being configured to hold the cushioning material (45, 50, 55) in place on a second side of the subject's head responsive to the subject's head being in place on the pillow system; - an adjustable portion at a location proximate to the back of the subject's head that connects the first portion and the second portion, the adjustable portion providing adjustment to move to and retain spacing between the first portion and the second portion to accommodate differences in distances between the first side of the head and the second side of the head for different subjects; the pillow system further comprising: a first ear cup supported by the first portion and/or the cushioning material (45, 50, 55) adjacent the first portion at a position such that, responsive to the subject's head being in place on the pillow, the first ear cup surrounds the subject's ear on a first side of the subject's head; and a second ear cup supported by the second portion and/or the cushioning material (45, 50, 55) adjacent the second portion at a position such that, responsive to the subject's head being in place on the pillow, the second ear cup surrounds the subject's ear on a second side of the subject's head characterized in that the adjustable portion comprises: one or more springs that slidably connect the first portion and second portion and biases the first portion toward the second portion, or a ball catch system, wherein perforation holes in the first portion and the second portion are the catch of the ball catch system. cushioning material (45, 50, 55) configured to engage the back and sides of the subject's head responsive to the head of the subject being in place on the pillow system; a resilient frame configured to surround the back and sides of the subject's head to hold the cushioning material (45, 50, 55) in place on the subject's head, the frame comprising: - a first portion having a first inner side and a first outer side, the first portion being configured to hold the cushioning material (45, 50, 55) in place on a first side of the subject's head responsive to the subject's head being in place on the pillow system; - a second portion having a second inner side and a second outer side, the second portion being configured to hold the cushioning material (45, 50, 55) in place on a second side of the subject's head responsive to the subject's head being in place on the pillow system; - an adjustable portion at a location proximate to the back of the subject's head that connects the first portion and the second portion, the adjustable portion providing adjustment to move to and retain spacing between the first portion and the second portion to accommodate differences in distances between the first side of the head and the second side of the head for different subjects; - a first portion having a first inner side and a first outer side, the first portion being configured to hold the cushioning material (45, 50, 55) in place on a first side of the subject's head responsive to the subject's head being in place on the pillow system; - a second portion having a second inner side and a second outer side, the second portion being configured to hold the cushioning material (45, 50, 55) in place on a second side of the subject's head responsive to the subject's head being in place on the pillow system; - an adjustable portion at a location proximate to the back of the subject's head that connects the first portion and the second portion, the adjustable portion providing adjustment to move to and retain spacing between the first portion and the second portion to accommodate differences in distances between the first side of the head and the second side of the head for different subjects; a first ear cup supported by the first portion and/or the cushioning material (45, 50, 55) adjacent the first portion at a position such that, responsive to the subject's head being in place on the pillow, the first ear cup surrounds the subject's ear on a first side of the subject's head; and a second ear cup supported by the second portion and/or the cushioning material (45, 50, 55) adjacent the second portion at a position such that, responsive to the subject's head being in place on the pillow, the second ear cup surrounds the subject's ear on a second side of the subject's head one or more springs that slidably connect the first portion and second portion and biases the first portion toward the second portion, or a ball catch system, wherein perforation holes in the first portion and the second portion are the catch of the ball catch system.
