The flexible mount is comprised of an elastomeric material. The personal acoustic system further includes a band comprising a first mount and an earpiece comprising a second mount. An acoustic element is housed within the earpiece. The elastomeric mount is positioned intermediate the first mount and the second mount to flexibly connect the band to the earpiece. ## Claims ### Claim 1 An assembly, comprising: a headband comprising a first mount; an earpiece comprising a second mount and an electroacoustic speaker, wherein the second mount comprises a circumferential mounting surface; and an elastomeric grommet flexibly connecting the band to the earpiece, wherein the elastomeric grommet is positioned intermediate the first mount and the second mount, wherein the elastomeric grommet comprises an inner mounting surface, and wherein the inner mounting surface is positioned around the circumferential mounting surface to connect the elastomeric grommet to the earpiece. ### Claim 2 (depends on 1) The assembly of claim 1, wherein the first mount comprises an annular inner surface. ### Claim 3 (depends on 2) The assembly of claim 2, wherein the circumferential mounting surface comprises a groove, wherein a portion of the elastomeric grommet is positioned at least partially within the groove, and wherein the portion of the elastomeric grommet is friction-fit within the groove. ### Claim 4 (depends on 3) The assembly of claim 3, wherein the groove comprises an outer notched profile, and wherein the elastomeric grommet comprises an inner notched profile corresponding to the outer notched profile to prevent rotation of the elastomeric grommet relative to the earpiece. ### Claim 5 (depends on 1) The assembly of claim 1, wherein the elastomeric grommet is comprised of a first material, wherein the first mount is comprised of a second material, and wherein the second material is different than the first material. ### Claim 6 (depends on 5) The assembly of claim 5, wherein the elastomeric grommet and the headband comprise a co-molded subassembly. ### Claim 7 (depends on 3) The assembly of claim 3, wherein the elastomeric grommet comprises a groove, and wherein the annular inner surface is positioned at least partially within the groove. ### Claim 8 (depends on 7) The assembly of claim 7, wherein the groove comprises an outer notched profile, and wherein the annular inner surface comprises an inner notched profile corresponding to the outer notched profile. ### Claim 9 (depends on 1) The assembly of claim 1, wherein the elastomeric grommet is comprised of a material selected from a group consisting of thermoplastic elastomer and silicone. ### Claim 10 (depends on 1) The assembly of claim 1, wherein at least one relief feature is defined into the elastomeric grommet. ### Claim 11 An assembly, comprising: an earpiece comprising an acoustic element; and an integrally-formed subassembly, comprising: a band; and an elastomeric member, wherein the elastomeric member is positioned at least partially around at least a portion of the earpiece, and wherein the elastomeric member is coupled to the earpiece without additional fasteners. ### Claim 12 (depends on 11) The assembly of claim 11, wherein the elastomeric member is snap-fit around the portion of the earpiece. ### Claim 13 (depends on 11) The assembly of claim 11, wherein the elastomeric member is comprised of a material selected from a group consisting of thermoplastic elastomer and silicone, wherein the band is comprised of a material selected from a group consisting of metal and plastic, and wherein the earpiece is comprised of a material selected from a group consisting of metal and plastic. ### Claim 14 An assembly, comprising: a band comprising a first end portion and a second end portion; a first earpiece comprising a first electroacoustic speaker and a first annular mounting surface; a second earpiece comprising a second electroacoustic speaker and a second annular mounting surface; a first elastomeric grommet flexibly connecting the first end portion of the band to the first earpiece, wherein the first elastomeric grommet comprises a first inner mounting surface, and wherein the first inner mounting surface is positioned around the first annular mounting surface to connect the first elastomeric grommet to the first earpiece; and a second elastomeric grommet flexibly connecting the second end portion of the band to the second earpiece, wherein the second elastomeric grommet comprises a second inner mounting surface, and wherein the second inner mounting surface is positioned around the second annular mounting surface to connect the second elastomeric grommet to the second earpiece.
