## Abstract

A headset includes a housing provided at one end of a headband, an ear pad attached to the housing, a boom main body attached to the housing on a side opposite to the ear pad, an arm portion provided in the boom main body and protruding to a side opposite to one end of the headband with the housing interposed between the headband and the arm portion, a first microphone provided at a protruding tip of the arm portion, and a second microphone provided on the arm portion, and disposed on a substantially straight line passing through a mouth of a user and the first microphone and on a side opposite to the mouth of the user with the first microphone interposed between the mouth and the second microphone.

## Claims

### Claim 1

A headset comprising:
a housing at a first end of a headband;
an ear pad attached to the housing;
a boom main body attached to the housing on a side opposite to the ear pad;
an arm portion in the boom main body and protruding to a side opposite to the first end of the headband with the housing interposed between the headband and the arm portion;
a first microphone at a protruding tip of the arm portion; and
a second microphone on the arm portion, the second microphone being disposed on a substantially straight line passing through a mouth of a user and the first microphone and on a side of the arm portion opposite to the mouth of the user with the first microphone interposed between the mouth and the second microphone;
wherein the first microphone is disposed only on an arm inner surface at a mouth side of the arm portion, and the second microphone is disposed only on an arm outer surface of the arm portion at a side opposite to the arm inner surface.

### Claim 2 (depends on 1)

The headset of claim 1, further comprising an audio signal processor configured to generate a signal having directivity in a direction toward the mouth of the user based on audio signals collected respectively by the first microphone and the second microphone.

### Claim 3 (depends on 1)

The headset of claim 1, further comprising a third microphone disposed on the arm outer surface of the arm portion at a side opposite to the first microphone with the second microphone interposed between the first microphone and the third microphone.

### Claim 4 (depends on 3)

The headset of claim 3, wherein a distance between the second microphone and the third microphone is longer than a distance between the first microphone and the second microphone.

### Claim 5 (depends on 1)

The headset of claim 1, further comprising a power supply controller configured to turn off a power supply of the headset when the power supply controller detects a rotation of the arm portion to a position where the arm portion overlaps the headband by rotation of the arm portion with respect to the housing.

### Claim 6 (depends on 1)

The headset of claim 1, further comprising a power supply controller configured to turn on on a power supply of the headset when the power supply controller detects a rotation of the arm portion to a position where the arm portion protrudes to a side opposite to the first end of the headband with the housing interposed between the arm portion and the headband by rotation of the arm portion with respect to the housing.
