## Abstract

A headphone device includes a head pad, a band, and a sleeve. The head pad has a curved shape with a first radius of curvature. The band extends from an edge of the head pad into a curved shape with a second radius of curvature different from the first radius of curvature, and supports a housing, via a hanger, housing a speaker unit. The sleeve has a curved shape with the first radius of curvature and is slidable along the head pad to cover the band so as to change the radius of curvature at a part of the band covered with the sleeve to approximate to the first radius of curvature.

## Claims

### Claim 1

A headphone device comprising:
a head pad having a curved shape with a first radius of curvature;
a band extending from an edge of the head pad into a curved shape with a second radius of curvature different from the first radius of curvature, and supporting a housing, via a hanger, housing a speaker unit; and
a sleeve having a curved shape with the first radius of curvature and slidable along the head pad to cover the band so as to change the radius of curvature at a part of the band covered with the sleeve to approximate to the first radius of curvature.

### Claim 2 (depends on 1)

The headphone device according to claim 1, wherein the sleeve has a greater flexural rigidity than the band.

### Claim 3 (depends on 1)

The headphone device according to claim 1, wherein at least part of the sleeve is retractable into the head pad.

### Claim 4 (depends on 1)

The headphone device according to claim 1, wherein the sleeve includes a mark for indicating a slid amount of the sleeve with respect to the head pad.
