Ear saver

Device used to protect the wearer's face from hazards

An ear saver, also known as mask strain release strap or mask extender, is an accessory to personal protective equipment (PPE), relieves strain on a mask wearer's ears created through the loops of masks. Ear savers were designed as novel items during the COVID-19 pandemic by the open-source hardware community in response to requests from medical professionals reporting heavy strain on their ears. Ear savers have since been commercialized for a broader population of users as the pandemic wore on.
