Inmo recalls Air3 smart glasses after overheating temples caused 10 burn reports
↗
Inmo has issued a recall for its Air3 smart glasses in the US and Canada due to a left temple overheating defect that poses a burn hazard.
The recall highlights a critical thermal management failure in a wearable device worn directly against the skin. For engineers, the fact that the issue was known and mitigated with a physical sleeve before the formal recall indicates a gap between internal risk assessment and regulatory compliance. The remedy is a software update, suggesting the thermal limits were not properly enforced in the firmware.

The recall covers over 1,600 units sold between December 2025 and August 2026 in the US and Canada.
Ten users reported a burning sensation on the face and left ear, prompting the CPSC to classify it as a serious injury risk.
Inmo is providing a free software update to fix the issue, although reviews from seven months prior already noted the overheating problem.
THE READ
What the cluster adds up to.
Inmo has recalled its Air3 smart glasses following reports that the left temple overheats during extended use. The US Consumer Product Safety Commission (CPSC) identified this as a burn hazard that poses a risk of serious injury or death. The recall affects over 1,600 units sold in the US and Canada between December 2025 and August 2026. The company is directing users to stop using the device immediately and contact support for a remedy.
The technical failure is localized to the left temple, which users reported causing a burning sensation on the face and ear. This indicates a thermal management flaw in the hardware or firmware that allows the component to exceed safe skin-contact temperatures. The fact that the issue was present in reviews seven months before the formal recall suggests the defect was known to the manufacturer. Inmo had previously included a protective sleeve with the glasses to mitigate the heat, a stopgap that did not prevent the regulatory action.
The resolution for affected users is a free online software update rather than a hardware replacement. This implies that the overheating is controlled by firmware parameters that can be adjusted to limit power draw or temperature. For engineers, this case demonstrates the importance of enforcing thermal limits in software, especially for wearables where direct skin contact increases the risk of injury. The delay between the initial user reports and the formal recall highlights the risks of relying on physical mitigations instead of fixing the underlying control logic.
The recall was initiated in cooperation with the CPSC after ten specific reports of injury. The glasses were sold through Inmo's website, Amazon, and a Kickstarter campaign for prices between $900 and $1,300. The identification of the recalled units relies on a label printed on the right temple. This incident underscores the regulatory scrutiny applied to consumer electronics that interact closely with the human body, where thermal safety is a non-negotiable requirement.
