The headset may be shaped to provide a comfortable and proper seal to, for example, exclude ambient noise. In addition, the headset may configured to include various interchangeable components and may further include several input ports. Advantageously, the headset may be modular and may facilitate coupling with one or more interfaces, such as an audio source and a microphone. ## Claims ### Claim 1 A headset comprising: an earcup assembly; a headband assembly including a bracket, said headband assembly further including a cushion assembly removably coupled to said bracket, wherein a top section of said cushion assembly includes a channel for guiding a wire; one or more slots formed in said bracket, each slot configured to receive a locking mechanism, said locking mechanism operable for adjusting a distance between said headband assembly and said earcup assembly; and a post pivotally coupling said earcup assembly to said locking mechanism, said post configured to facilitate pivotal movement of said earcup assembly with respect to the headband assembly. ### Claim 2 (depends on 1) The headset of claim 1, wherein said top section is detachably coupled to a bottom section via a hook and loop fastener. ### Claim 3 (depends on 1) The headset of claim 1, wherein said cushion assembly is configured to connected to one or more stoppers of said headband assembly. ### Claim 4 (depends on 1) The headset of claim 1, wherein said locking mechanism is a cam assembly including a housing comprising a cam and a lock pad, said locking mechanism configured to compress around said bracket. ### Claim 5 (depends on 4) The headset of claim 4, wherein said cam assembly includes a thumb pad having a pin extending through said one or more slots and rotatably coupled to said cam of said housing. ### Claim 6 (depends on 5) The headset of claim 5, wherein said pin is operable to rotate said cam between a locked position and an unlocked position. ### Claim 7 (depends on 6) The headset of claim 6, wherein said cam comprises a front surface having one or more depressions and one or more protrusions, said depressions corresponding to the unlocked position and said protrusions corresponding to the locked position. ### Claim 8 (depends on 1) The headset of claim 1, wherein said post is curved to conform to a shape of said earcup assembly. ### Claim 9 (depends on 1) The headset of claim 1, wherein said earcup assembly is D-shaped. ### Claim 10 (depends on 1) The headset of claim 1, wherein said earcup assembly comprises a frame, a driver assembly, and an earpad. ### Claim 11 (depends on 10) The headset of claim 10, wherein said driver assembly is detachably connected to said frame. ### Claim 12 (depends on 10) The headset of claim 10, wherein said earpad is detachably connected to said driver assembly. ### Claim 13 (depends on 10) The headset of claim 10, wherein said earpad is formed of a one or more layers. ### Claim 14 (depends on 13) The headset of claim 13, wherein at least one layer is made of alcantara. ### Claim 15 (depends on 13) The headset of claim 13, wherein said one or more layers includes at least one of a memory foam layer and a cooling gel layer. ### Claim 16 (depends on 1) The headset of claim 1, wherein said earcup assembly includes a bayonet-type mount configured to connect to a corresponding bayonet-type fastener. ### Claim 17 (depends on 1) The headset of claim 1, further comprising a first input port and a second input port. ### Claim 18 (depends on 17) The headset of claim 17, wherein said first input port is configured to couple with an audio source and said second input port is configured to couple with a microphone. ### Claim 19 A headset including a cam assembly, the headset comprising: an earcup assembly; a headband assembly including a bracket; one or more slots formed in said bracket; a cam assembly including a housing and a thumb pad, said thumb pad including a pin extending through said one or more slots and rotatably coupled to a cam of said housing such that cam assembly is configured to adjust a distance between said headband assembly and said earcup assembly; and a post pivotally coupling said earcup assembly to said locking mechanism, said post configured to facilitate pivotal movement of said earcup assembly with respect to the headband assembly. ### Claim 20 (depends on 19) The headset including a cam assembly of claim 19, wherein said pin is further configured to rotate said cam between a locked position and an unlocked position.
