Techniques for guiding perspiration to desired channels to avoid negative impacts to electrical and mechanical functions of extended-reality devices, and systems and methods of use thereof

A mixed-reality (MR) headset, comprising:

• a two-part housing configured to house electronic and mechanical components used to present MR content, the two-part housing including a first part of the two-part housing and a second part of the two-part housing;
• and
• a channel formed by coupling the first part of the two-part housing to the second part of the two-part housing, the channel defined by a first portion of a first perimeter of the first part of the two-part housing overlapping a first portion of a second perimeter of the second part of the two-part housing, wherein a second portion of the second perimeter of the second part of the two-part housing extends away from the channel,
• wherein:
• the channel is configured to guide perspiration along the first perimeter of the first part or the second perimeter of the second part away from the electronic and mechanical components housed in the two-part housing.
