October 30, 2026 — A user of Shokz OpenFit Open-Ear True Wireless Earbuds has reported discovering a swollen and leaking battery in one earpiece during normal operation. The incident, which occurred in late September 2026, highlights potential fire and chemical exposure risks associated with lithium-ion battery failures, though no injury or property damage was sustained in this specific case.
Product Details
Incident Overview
On or about September 25, 2026, a consumer reported that during normal use of their Shokz OpenFit Open-Ear True Wireless Earbuds, they noticed one earpiece had a swollen battery that was leaking liquid, identified as battery electrolyte. The user immediately ceased using the earbuds and has not used or charged the unit since the discovery. Fortunately, no fire occurred, no personal injury was sustained, and no property damage is known to have resulted from this incident.
It is important to note the specific timeline of this product. The original Shokz OpenFit earbuds were purchased on November 9, 2023, from shokz.com. The unit involved in this incident, however, was a warranty replacement received by the consumer around mid-November 2025. This replacement unit was provided after the original unit’s charging case had failed under a previous warranty claim.
Safety Concerns
A swollen and leaking lithium-ion battery, like the one reported in the Shokz OpenFit earbuds, poses significant safety concerns due to the inherent risks associated with battery failures.
- Immediate Dangers: The primary immediate danger is the risk of fire or thermal runaway. Swollen batteries indicate an internal chemical reaction that can generate excessive heat, potentially leading to combustion, explosions, or ignition of nearby materials. The leaking liquid, which is battery electrolyte, is also corrosive and can cause chemical burns upon skin contact or irritation if inhaled.
- Long-Term Risks: Even if no immediate fire or injury occurs, a compromised battery can continue to degrade, potentially leading to further swelling, leakage, or even a delayed thermal event. Exposure to battery chemicals over time can have adverse health effects.
- Who Might Be Affected: Anyone using or in proximity to the affected earbuds could be at risk. This includes the user, family members, or individuals in shared spaces where the product is stored or used. Children, who may be more susceptible to chemical exposure or unaware of the dangers, are particularly vulnerable.
- Property Damage Potential: A battery fire, even a small one, can quickly spread and cause substantial damage to personal property, including clothing, furniture, or electronic devices, and potentially lead to structural damage in a home.
What Consumers Should Do
If you own Shokz OpenFit Open-Ear True Wireless Earbuds, especially if they are a warranty replacement unit, it is crucial to be aware of these potential risks.
- Immediate Steps to Take: If you observe any swelling, bulging, leaking, or unusual heat from your earbuds or charging case, immediately stop using the product. Do not attempt to charge, use, or repair the device. Place the product in a non-flammable container (like a metal tin) away from flammable materials.
- How to Check for Affected Product: Regularly inspect your earbuds for any signs of physical changes, including bulging or swelling of the earpieces or charging case, discolored areas, or any unusual odors.
- Prevention Measures: Always use the manufacturer-provided charging cables and power adapters. Avoid exposing earbuds to extreme temperatures, direct sunlight, or physical damage. Do not drop, crush, or puncture the battery.
- Reporting Procedures: If you experience a similar incident, report it immediately to the manufacturer, Shokz Technology Inc., and to the U.S. Consumer Product Safety Commission (CPSC) at SaferProducts.gov. Detailed reports are crucial for identifying potential widespread issues and prompting necessary safety actions.
