DETAILED DESCRIPTION
In competitive gaming environments, modern headsets are connected to an audio exchange with boom assemblies that support microphones, easing communications among teammates without the need to shout to be heard. In various embodiments of the present subject matter, earphones, which convert electrical energy into sound waves, are designed with a grille, which is configured as a permeable layer to receive sounds produced externally in the gaming environment, in combination with a noise plate, which is configured to attenuate or eliminate noise, when the noise plate covers the grille. The visibility of the noise plate also provides a platform on which art work, advertisements, insignia, trademarks, designs, and so on, are displayed. Each noise plate also has an aperture that guides a jack of a boom assembly into internal audio components to receive communications uttered by a wearer. The boom assembly can be removably detached and attached to either the right earphone or the left earphone, depending on the preference of the wearer.
FIGS. 1A, 1B illustrate a headset 100 that comprises a pair of earphones 101a, 101b held over a gamer's ears by a pair of bands 108a, 108b worn over the head. Each earphone 101a, 101b includes a pad 102a, 102b, which envelops the ear by enclosing it completely. Each earphone 101a, 101b includes a frame 106a, 106b that is mechanically coupled to a shell 102a, 102b. The shell 102a, 102b is further mechanically coupled to the pad 102a, 102b to enclose assembled parts residing between the pad 102a, 102b and the shell 104a, 104b, as well as providing rigidity to the structure of each earphone 101a, 101b. 
Each earphone 101a, 101b includes a noise plate 110 to provide insulation against distracting noise that is produced in a competitive environment, such as during gaming tournaments. The noise plate 110 can be removed by exerting a force greater than the magnetic coupling that fastens the noise plate 110 to the earphone 101a, 101b so as to allow the wearer of the headset 100 to hear teammates shouting out during tournaments. The noise plate 110 includes an aperture 112 that guides a jack 116 of a boom assembly 114 to mate with a female port (not shown) of the earphone 101a, 101b. When connected, the wearer of the headset 100 may audibly communicate via utterances that are received by the microphone screen 118 for transmission to audio circuitry components (not shown).
The earphones 101a, 101b are mechanically coupled to the band 108a, 108b via hollowed cylinders 120a, 120b. Protected by these cylinders 120a, 120b are audio wires that transmit audio communication to the earphones 101a, 101b. These audio wires also receive audio communication received from the boom assembly 114 for transmission to other audio processing circuitry (not shown). FIG. 1B illustrates that the earphone 101a can be rotated about 90 degrees. The earphone 101b can be similarly rotated. When the wearer of the headset 100 rests the headset 100 on his neck, both earphones 101a, 101b may be rotated so that the pads 102a, 102b engage his chest, and in this manner, add comfort as well as exposing art work, advertisements, insignia, trademarks, designs, etc., on the noise plates 110a, 110b. 
FIGS. 2-3 illustrate an exemplary earphone 101 presented in an exploded perspective view. The earphone 101 includes the noise plate 110. The noise plate 110 is rectangular in shape and includes an aperture 112 for guiding jack 116 to audio circuitry (not shown) to transmit audio information received by the boom assembly 114. The earphone 101 includes a gasket 202 having an annular shape for defining an opening 202f. Multiple holes 202a-202d are provided near the corners of the gasket 202. These holes allow magnetic members 210a-210d to magnetically couple the noise plate 110 to other assembled parts of the earphone 101. The gasket 202 includes an aperture 202e to cooperatively communicate with the aperture 112 for guiding jack 116 to mate with audio circuitry (not shown) of the earphone 101.

A hollowed, projected cylinder 204e protrudes into the aperture 202e of the gasket 202 which terminates at the aperture 112 of the noise plate 110 to further help guide the jack 116 of the boom assembly 114 to mate with audio circuitry (not shown) of the earphone 101.
The earphone 101 includes a frame 106 characterized by its U-shaped racetrack form. Protruding at an angle from one side of either arm of the U-shaped frame 106 is a hollowed cylinder 206a, 206b that engages openings 208a, 208b of the earphone 101 to allow the frame 106 to cradle at various angles, hence adding comfort to the wearer of the earphone 101.
The earphone 101 includes the shell 104 having two open ends. The diameter of a proximal end of the shell 104 tapers gradually to a distal end of the shell 104 to form a neck. Two openings 208a, 208b on either side of the neck of the shell 104 mate with projected hollowed cylinders 206a, 206b of the frame 106, thus allowing the frame 106 to cradle against the shell 104. A notch 208c located at the distal end of the shell 104 is configured to receive speaker wire for transmitting audio information into the earphone 101.
The earphone 101 includes a bezel 210 on which electrical, electronic, and mechanical parts of a speaker system are assembled. The earphone 101 includes a pliant, annular member 212, whose center opening permits audio sound reproduced by the speaker system housed by the bezel 210 to be projected. Multiple holes 212a-212d couple the annular member 212 to the bezel 210. The pad 102 is a component of the earphone 101 that envelops the ear of the wearer of the earphone 101.
FIG. 3 reveals elements not readily visible with the illustration in FIG. 2. The noise plate 110 of the earphone 101 includes multiple projected, hollowed cylinders 110a-110c to accommodate magnetic members 210a-210d to magnetically couple the noise plate 110 to other assembled parts of the earphone 101. The boom assembly 114 includes a proximal end that houses jack 116 and a distal end for accommodating a microphone screen 118. The projected, hollowed cylinders 206a, 206b are more clearly illustrated by the exploded, perspective view of the earphone 101 presented from the back as shown in FIG. 3.

One portion is a fitting of manufactured parts of the earphone 101 that includes an assembly comprising the shell 104, the frame 106, and the noise plate 110. The notch 208c into which earphone wires are guided to assembled parts of the earphone 101 is visible. The aperture 112 of the noise plate 110 guides the jack 116 of the boom assembly 114 to mechanically and electrically communicate with a clutch 214, which belongs to the other portion of the earphone 101.
The clutch 214 is housed by the bezel 210. The bezel 210 is one part in an assembly of parts, including the pad 102 and the annular member 212, which together comprise another fitting of manufactured parts of the earphone 101. Specifically, the clutch 214 comprises three fingers 214a-214c that grip a jack collar 402 to seize the boom assembly 114 firmly while allowing the jack 116 to be in electrical communication with the wire form 216 and other assembled parts of the bezel 210 as well as allowing the boom assembly 114 to be coaxially rotated (in the direction where the jack 116 is inserted into the clutch 214). Multiple magnetic members 210a-210d are shown floating in the illustration to illustrate its fastening function to magnetically couple the bezel 210 to the other parts of the earphone 101.
FIG. 5 illustrates the boom assembly 114 using a perspective view. The boom assembly 114 includes a boom overmold 504 at a proximal end to house the jack collar 402 that is used to house the jack 116 at its base 502. At the distal end of the boom assembly 114, a microphone receiver is hidden behind the microphone screen 118, which is longitudinally aligned with the front microphone housing 508. Supporting the front microphone housing 508 and the microphone screen 118 is a back 506 of the microphone housing.
FIG. 6 illustrates a collection of parts so assembled to form a portion of the earphone 101. The collection of parts includes the pad 102, the annular member 212, and the bezel 210. The multiple magnetic members 210a-210d mate with metallic female members 602a-602d that are characterized as projected, hollowed cylinders, and whose ends include metallic exposures to correspondingly mate with the multiple magnetic members 210a-210d. The bezel 210 includes the clutch 214, which is formed from three fingers 214a-214c, perpendicularly projected from a rectangular platform 606 and fastened to the bezel 210 via screws. Wound around the distal ends of the fingers 214a-214c is a wire form 216 that is configured to mechanically couple with the jack 116 of the boom assembly 114 by providing tension to retain the jack 116. Each finger 214a-214c, at the distal end, has a groove into which the wire form 216 is set so as to prevent slippage of the wire form 216 from the fingers 214a-214c. A PC board 604 containing audio circuitry lies on the finger 214a and superjacent to the PC board 604 are the fingers 214b, 214c. 
The bezel 210 includes a driver protector 608 that is characterized by its annular shape including two wings 608a, 608b. The driver protector 608 is fastened to the bezel 210 using a suitable fastening agent, such as glue. The wings of the driver protector 608 mate with two C-shaped members 614a-614b to prevent slippage of the driver protector 608.
