5 . The device of claim 2 , wherein the triggered digital interaction further comprises facilitating a payment transaction between at least one of a device-to-device, device-to-vendor POS terminal, or device-to-vendor product code.

6 . The device of claim 1 , wherein said CoS signaling element displays a pre-defined static color display, pre-defined static sequence of color display, pre-defined flashing of a color, or a pre-defined flashing sequence of colors on said CoS signaling element.

7 . The device of claim 1 , further comprising a second user device for pairing and interaction with being any wearable device with at least a line-of-sight or a CoS.

8 . The device of claim 7 , wherein the pairing and/or digital interaction comprises decoding a tag sent by the first CoS device within range by a second user wearable device upon matching of color/symbol-coded interaction rules displayed on the first and second user devices.

9 . The device of claim 8 , wherein the decoded tag comprises at least one of a sound via the audio output element on said housing, vibration via a haptic output element on said housing, pre-defined static color display, pre-defined static sequence of color display, pre-defined flashing of a color, or a pre-defined flashing sequence of colors on said CoS signaling element.

10 . The device of claim 8 , wherein the decoded tag further comprises mirroring at least one of the audio output, haptic output, pre-defined static display, or pre-defined flashing display on the first users and second users mobile devices and/or upload over a network to a social networking site.

11 . The device of claim 8 , wherein the decoded tag triggers an exchange of at least one of a profile content or a social media content between the first and second user over a network.

12 . The device of claim 11 , wherein the content exchange between the first and the second user is displayed on the mobile device of the first and the second user.

13 . The device of claim 1 , wherein the light display signals at least one of an affiliation, support-of-cause, call-receiving, call-dialing, call-in-progress, audio-in-progress, audio type-in-progress, free-for-approach, awaiting approach, approach confirmed, second user pairing-in-progress, second user tag-decoding-in-progress, confirmation of tag-decoding, digital interaction-in-progress, confirmation of digital interaction completion, transaction-in-progress, confirmation of transaction, health status, proximity alert, confirmation of legal age, or an unwillingness for approach.

14 . The device of claim 13 , wherein the signaling of a health status is based on a most recent test result from any one of a health institution, health provider, or public health registry.

15 . The device of claim 13 , wherein the light display of a color from the CoS signaling element signals a COVID-19 negative test result within a pre-defined period of time and a different color signals a COVID-19 result ambiguity.

16 . The device of claim 13 , wherein the light display color from the CoS signaling element signals a proximity of at least one other non-designated person within six feet beyond a pre-defined period of time.

17 . The device of claim 1 , wherein the CoS signaling element displays light in at least one of a solid-colored, broken-colored, mix-colored, color-patterned or colored-flash scheme based on a pre-defined signaling protocol.

18 . The device of claim 1 , further comprising a covert CoS display characterized by at least one type of an obscurement (altered light intensity or pattern display) only discernable to at least one of a select CoS viewer or LoS viewer (select viewer) based on a decoding of a tag sent by the user or triggering a digital interaction between the user and the select viewer.

19 . A circle-of-sight signaling (CoS) element strip device, said device comprising:

a circle-of-sight (CoS) signaling element in the form of a lighting strip, wherein the strip is dimensioned and configured to adhere to a surface of a housing of a wireless over-the-ear headphone device;
