The first fastener and the second fastener may detachably secure the strap to the body of the HMD system. Various other methods and systems are also disclosed. ## Claims ### Claim 1 A head-mounted display system, comprising: a body having a right side and a left side; a display device coupled to the body such that, when the head-mounted display system is donned by a user, the display device is positioned to display content to the user; a right side arm coupled to the right side of the body, the right side arm being dimensioned to be detachably coupled to a first portion of a swappable head strap; and a left side arm coupled to the left side of the body, the left side arm being dimensioned to be detachably coupled to a second portion of the swappable head strap. ### Claim 2 (depends on 1) The head-mounted display system of claim 1, wherein either one or both of the right side arm and the left side arm are configured to accommodate a respective electronic component. ### Claim 3 (depends on 2) The head-mounted display system of claim 2, wherein the respective electronic component is an audio transducer. ### Claim 4 (depends on 1) The head-mounted display system of claim 1, further comprising either one or both of: a first snap piece disposed on the first portion of the swappable strap and configured to snap onto the right side arm to detachably couple the right side arm to the first portion of the swappable strap; and a second snap piece disposed on the second portion of the swappable strap and configured to snap onto the left side arm to detachably couple the left side arm to the second portion of the swappable strap. ### Claim 5 (depends on 4) The head-mounted display system of claim 4, wherein: the first snap piece includes a first lip configured to fit around an edge of the right side arm; and the second snap piece includes a second lip configured to fit around an edge of the left side arm. ### Claim 6 (depends on 4) The head-mounted display system of claim 4, wherein the first and second snap pieces are made of a material that is more rigid than a material of the swappable strap. ### Claim 7 (depends on 4) The head-mounted display system of claim 4, wherein: the first and second snap pieces are made of a plastic, a metal, or a ceramic; and the swappable strap is made of a woven fabric, an elastic, a knitted fabric, a fibrous fabric, or a webbing. ### Claim 8 A strap assembly for head-mounted display system, the strap assembly comprising: a strap configured to fit around a head of a user; a first fastening piece disposed on a first portion of the strap and configured to be detachably coupled to a right side arm of the head-mounted display system; and a second fastening piece disposed on a second portion of the strap and configured to be detachably coupled to a left side arm of the head-mounted display system. ### Claim 9 (depends on 8) The strap assembly of claim 8, wherein: the first fastening piece is configured to fit over an edge of the right side arm; and the second fastening piece is configured to fit over an edge of the left side arm. ### Claim 10 (depends on 8) The strap assembly of claim 8, wherein: the first fastening piece includes a first lip configured to fit around an edge of the right side arm; and the second fastening piece includes a second lip configured to fit around an edge of the left side arm. ### Claim 11 (depends on 10) The strap assembly of claim 10, wherein: the first lip is configured to snap onto the right side arm; and the second lip is configured to snap onto the left side arm. ### Claim 12 (depends on 8) The strap assembly of claim 8, wherein the first and second fastening pieces are made of a material that is more rigid than a material of the strap. ### Claim 13 (depends on 8) The strap assembly of claim 8, wherein: the first and second fastening pieces are made of a plastic, a metal, or a ceramic; and the swappable strap is made of a woven fabric, an elastic, a knitted fabric, a fibrous fabric, or a webbing. ### Claim 14 (depends on 8) The strap assembly of claim 8, wherein: the first fastening piece is bonded to the first portion of the strap; and the second fastening piece is bonded to the second portion of the strap. ### Claim 15 A method of assembling a head-mounted display system, the method comprising: attaching a right side arm to a right side of a body of a head-mounted display system; attaching a left side arm to a left side of the body of the head-mounted display system; dimensioning the right side arm for detachably coupling to a strap assembly; and dimensioning the left side arm for detachably coupling to the strap assembly, wherein the strap assembly comprises: a strap configured to fit around a head of a user; a first fastening piece disposed on a first portion of the strap and configured to be detachably coupled to the right side arm; and a second fastening piece disposed on a second portion of the strap and configured to be detachably coupled to the left side arm. ### Claim 16 (depends on 15) The method of claim 15, further comprising configuring either one or both of the right side arm and the left side arm to accommodate a respective electronic component. ### Claim 17 (depends on 16) The method of claim 16, wherein the respective electronic component is an audio transducer. ### Claim 18 (depends on 15) The method of claim 15, wherein: the first fastening piece includes a first lip configured to fit around an edge of the right side arm; and the second fastening piece includes a second lip configured to fit around an edge of the left side arm. ### Claim 19 (depends on 18) The method of claim 18, wherein: the first lip is configured to snap onto the edge of the right side arm; and the second lip is configured to snap onto the edge of the left side arm. ### Claim 20 (depends on 18) The method of claim 18, wherein: the first lip is configured to snap onto the right side arm; and the second lip is configured to snap onto the left side arm.
