At least one of the biometric sensors is configured to be pressed up against a portion of the tragus for making biometric measurements. In some embodiments, the housing of the earbud can be symmetric so that the earbud can be worn interchangeably in either a left or a right ear of a user. In such an embodiment, the earbud can include a sensor and circuitry configured to determine and alter operation of the earbud in accordance to which ear the earbud is determined to be sitting in. ## Claims ### Claim 1 An earbud, comprising: an earbud housing defining an audio exit opening; a speaker disposed within the earbud housing and oriented so that audio emitted by the speaker exits the earbud housing through the audio exit opening; and a compliant member configured to anchor the earbud to a user's ear and having first and second ends coupled to the earbud housing at first and second anchoring locations, respectively, the compliant member comprising a loop of flexible material having first and second portions and a reinforcing member disposed within the first portion of the loop of flexible material such that the first portion of the loop has a higher rigidity than the second portion of the loop. ### Claim 2 (depends on 1) The earbud as recited in claim 1, wherein the first portion of the loop and the second portion of the loop are the same size. ### Claim 3 (depends on 1) The earbud as recited in claim 1, wherein the compliant member is formed from an elastomeric material that is less rigid than the reinforcing member. ### Claim 4 (depends on 3) The earbud as recited in claim 3, wherein the reinforcing member comprises a length of spring steel. ### Claim 5 (depends on 1) The earbud as recited in claim 1, wherein the compliant member further comprises a third portion of the loop and wherein another reinforcing member is disposed within the third portion of the loop such that the first and third portions of the loop are more rigid than the second portion of the loop. ### Claim 6 (depends on 5) The earbud as recited in claim 5, wherein the first and third portions of the loop are closer to the earbud housing than the second portion of the loop. ### Claim 7 An earbud, comprising: a speaker; an electrical component electrically coupled to the speaker; an earbud housing, comprising: a first housing component enclosing the speaker; and a second housing component enclosing the electrical component and being removably coupled to the first housing component; and a compliant member configured to anchor the earbud to a user's ear and having first and second ends coupled to the earbud housing at first and second anchoring locations, respectively, the compliant member comprising a loop of flexible material having first and second portions and a reinforcing member disposed within the first portion of the loop of flexible material such that the first portion of the loop has a higher rigidity than the second portion of the loop. ### Claim 8 (depends on 7) The earbud as recited in claim 7, wherein the second housing component comprises a protrusion that engages a channel defined by the first housing component to removably couple the second housing component to the first housing component. ### Claim 9 (depends on 8) The earbud as recited in claim 8, wherein the protrusion is a puzzle shaped protrusion and the second housing component is configured to be decoupled from the first housing component by sliding the puzzle shaped protrusion out of the channel. ### Claim 10 (depends on 8) The earbud as recited in claim 8, wherein the protrusion comprises one or more environmental seals that inhibit intrusion of liquid between the first and second housing components. ### Claim 11 (depends on 8) The earbud as recited in claim 8, wherein the protrusion comprises a locking feature that opposes removal of the second housing component from the first housing component. ### Claim 12 (depends on 7) The earbud as recited in claim 7, wherein the second housing component further comprises a the first and second anchoring locations. ### Claim 13 (depends on 7) The earbud as recited in claim 7, wherein the first housing component comprises a first electrical contact at an exterior surface of the first housing component and the second housing component comprises a second electrical contact at an exterior surface of the second housing component, wherein the first and second electrical contacts form a portion of an electrically conductive pathway that electrically couples the electrical component to the speaker. ### Claim 14 (depends on 7) The earbud as recited in claim 7, wherein the electrical component is selected from the group consisting of a battery, memory, a sensor and a microphone. ### Claim 15 An earbud, comprising: an earbud housing defining an audio exit opening; a speaker disposed within the earbud housing; and a compliant member configured to anchor the earbud to a user's ear, comprising: a reinforcing member; and a loop of flexible material having first and second ends coupled to the earbud housing at first and second anchoring locations, the loop of flexible material having a first portion that encloses the reinforcing member and a second portion, the reinforcing member making the first portion of the loop more rigid than the second portion of the loop. ### Claim 16 (depends on 15) The earbud as recited in claim 15, wherein the second portion is farther from the earbud housing than the first portion. ### Claim 17 (depends on 16) The earbud as recited in claim 16, wherein the compliant further comprises a third portion of the loop and another reinforcing member is disposed within the third portion of the loop such that the first and third portions of the loop are more rigid than the second portion of the loop. ### Claim 18 (depends on 17) The earbud as recited in claim 17, wherein the first and third portions of the loop are closer to the earbud housing than the of the loop. ### Claim 19 (depends on 15) The earbud as recited in claim 15, wherein the reinforcing member comprises a length of steel.
