The ear tip includes a hollow main body having a first end defining a first opening and a second end defining a second opening for coupling to a coupling portion of a housing of the earpiece, and a peripheral portion integrally coupled to an outer surface of the first opening and shaped to conform to a surface of an ear canal. The peripheral portion has an outer edge with a plurality of wedge-shaped apertures formed integrally and spaced around the outer edge. The second opening and/or the coupling portion of the housing are adapted to be acoustically coupled with each other. ## Claims ### Claim 1 An ear tip for increasing mid-range frequency perception of an earpiece, comprising: a hollow main body comprising: a first end of the main body defining a first opening; and a second end of the main body defining a second opening for coupling to a coupling portion of a housing of the earpiece; and a peripheral portion integrally coupled to an outer surface of the first opening and shaped to conform to a surface of an ear canal, wherein the peripheral portion has an outer edge with a plurality of wedge-shaped apertures formed integrally and spaced around the outer edge, and wherein the second opening and/or the coupling portion of the housing are adapted to be acoustically coupled with each other. ### Claim 2 (depends on 1) The ear tip of claim 1, wherein when coupled to the earpiece has a measured SPL corresponding to a mid-range frequency, and the measured SPL corresponding to the mid-range frequency increases by at least 2 dB as compared to the earpiece coupled with a control ear tip from about 1.5 kHz to about 3 kHz, wherein the control ear tip has a fully intact peripheral portion without any apertures and/or wherein optionally the control ear tip is capable of forming a complete seal in the ear canal. ### Claim 3 (depends on 1) The ear tip of claim 1, wherein each of the plurality of wedge-shaped apertures has a wedge angle of between 40 to 60 degrees. ### Claim 4 (depends on 1) The ear tip of claim 1, wherein the main body and the peripheral portion are made from an elastomer material. ### Claim 5 (depends on 1) The ear tip of claim 1, wherein the main body and the peripheral portion are made from a first material and a second material respectively. ### Claim 6 (depends on 1) The ear tip of claim 1, wherein the first opening and the second opening are of different sizes and/or shapes. ### Claim 7 (depends on 1) The ear tip of claim 1, wherein the wedge-shaped apertures are formed with rounded corners and/or edges. ### Claim 8 (depends on 1) The ear tip of claim 1, wherein the peripheral portion and the wedge-shaped apertures are formed by injection molding. ### Claim 9 (depends on 1) The ear tip of claim 1, wherein the plurality of wedge-shaped apertures comprises of at least four wedge-shaped apertures. ### Claim 10 (depends on 9) The ear tip of claim 9, wherein the earpiece has a measured SPL corresponding to a mid-range frequency, and the measured SPL corresponding to the mid-range frequency increases by at least 5 dB as compared to the earpiece coupled with a control ear tip from about 1.5 kHz to about 3 kHz, wherein the control ear tip has a fully intact peripheral portion without any apertures and/or wherein optionally the control ear tip is capable of forming a complete seal in the ear canal. ### Claim 11 An earpiece comprising: a housing defining an acoustic passage to deliver sound energy as an acoustic source; and an ear tip detachably coupled to the housing, comprising: a hollow main body comprising: a first end of the main body defining a first opening; and a second end of the main body defining a second opening for detachably coupling to the acoustic passage; and a peripheral portion integrally coupled to an outer surface of the first opening and shaped to conform to a surface of an ear canal, wherein the peripheral portion has an outer edge with a plurality of wedge-shaped apertures formed integrally and spaced around the outer edge, and wherein the second opening and/or the acoustic passage are adapted to be acoustically coupled with each other. ### Claim 12 (depends on 11) The earpiece of claim 11, wherein the earpiece has a measured SPL corresponding to a mid-range frequency, and the measured SPL corresponding to the mid-range frequency increases by at least 2 dB as compared to the earpiece coupled with a control ear tip from about 1.5 kHz to about 3 kHz wherein the control ear tip has a fully intact peripheral portion and/or wherein optionally the control ear tip is capable of forming a complete seal in the ear canal. ### Claim 13 (depends on 11) The earpiece of claim 11, wherein each of the plurality of wedge-shaped apertures has a wedge angle of between 40 to 60 degrees. ### Claim 14 (depends on 11) The earpiece of claim 11, wherein the main body and the peripheral portion are made from an elastomer material. ### Claim 15 (depends on 11) The earpiece of claim 11, wherein the main body and the peripheral portion are made from a first material and a second material respectively. ### Claim 16 (depends on 11) The earpiece of claim 11, wherein the first opening and the second opening are of different sizes and/or shapes. ### Claim 17 (depends on 11) The earpiece of claim 11, wherein the wedge-shaped apertures are formed with rounded corners and/or edges. ### Claim 18 (depends on 11) The earpiece of claim 11, wherein the peripheral portion and the wedge-shaped apertures are formed by injection molding ### Claim 19 (depends on 11) The earpiece of claim 11, wherein the plurality of wedge-shaped apertures comprises of only four wedge-shaped apertures. ### Claim 20 (depends on 19) The earpiece of claim 19, wherein the earpiece has a measured SPL corresponding to a mid-range frequency, and the measured SPL corresponding to the mid-range frequency increases by at least 5 dB as compared to the earpiece coupled with a control ear tip from about 1.5 kHz to about 3 kHz, wherein the control ear tip has a fully intact peripheral portion and/or wherein optionally the control ear tip is capable of forming a complete seal in the ear canal.
