Bose, the renowned audio equipment manufacturer, has issued a significant safety recall for the lithium-ion battery packs used in its popular S1 Pro and S1 Pro+ portable speaker systems. The recall, announced this past Thursday in coordination with the United States Consumer Product Safety Commission (CPSC), affects approximately 670,000 units across North America. Specifically, the recall covers roughly 635,000 battery packs in the United States and another 35,400 units in Canada, citing serious concerns regarding overheating and the potential risk of fire.
The recall represents a major operational response for the company, as the affected components were sold as part of their flagship portable PA systems for nearly a decade. While the speaker units themselves remain safe to use, Bose and federal safety regulators have urged owners to immediately discontinue the use of the affected battery packs to prevent potential burn injuries or property damage.
According to the official notification, Bose has received seven reports of the battery packs exhibiting dangerous behavior, including instances where the units melted, emitted smoke, or outright caught fire. These incidents have resulted in six documented cases of property damage. Fortunately, there have been no reports of personal injuries associated with these incidents to date. The decision to initiate a widespread recall serves as a proactive measure to ensure the safety of the consumer base, given the potential for these lithium-ion cells to experience thermal runaway.
The Bose S1 Pro and its successor, the S1 Pro+, are highly regarded in the professional audio community as versatile, portable PA systems. They have become fixtures at outdoor events, small musical gigs, and social gatherings due to their compact design and robust feature set, which includes built-in mixers and Bluetooth connectivity. A key selling point for these devices is their mobility, facilitated by a removable lithium-ion battery pack that allows users to operate the speakers without being tethered to an electrical outlet. The S1 Pro+ model further expanded the ecosystem by supporting wireless microphone and instrument transmitters, which are available as separate accessories.
The scope of this recall is vast, spanning products sold through a wide range of retail channels between December 2017 and July 2026. Consumers who purchased their S1 Pro or S1 Pro+ speakers through major retailers such as Best Buy, Amazon, Walmart, or directly from Bose’s own retail channels may be in possession of an affected unit. These battery packs were either included in the box with the purchase of the speakers—which typically retail for around $700—or purchased as standalone accessories for between $100 and $160. Given the long window of time these products have been on the market, the recall impacts a significant number of households, event spaces, and professional musicians who rely on these systems for their work.
It is important to note that not every battery pack produced for these speakers is subject to the recall. Bose has established a verification process to help owners determine if their specific battery pack poses a risk. To check if a unit is affected, owners must remove the battery pack from their speaker and locate the 17-digit serial number printed on the device. Once identified, this serial number should be compared against the list of affected batches provided by the company.
The specific serial numbers subject to the recall are those that begin with the following prefixes: 083723, 078352, 084105, 078591, 078592, 084106, or 086409. For owners who find that their battery serial number matches one of these sequences, Bose has established a dedicated recall portal on their support website where they can register to receive a free, safe replacement battery. The company has also provided comprehensive documentation and instructions to guide users through the identification and replacement process.
While the recall process is underway, Bose has clarified that the speakers themselves are not defective. Owners who are waiting for their replacement battery pack to arrive can continue to use their S1 Pro or S1 Pro+ speakers without issue, provided they plug the unit directly into an AC power source. This ensures that users who rely on these systems for professional commitments or scheduled events are not left entirely without their equipment, though the portability aspect of the speaker will be temporarily disabled until a non-recalled battery is secured.
The disposal of the affected lithium-ion batteries is a matter that regulators and the company are emphasizing with caution. Consumers are explicitly warned against discarding these potentially volatile batteries in standard household trash or recycling bins. Lithium-ion batteries can pose a significant fire hazard in waste management facilities and transport vehicles if they are crushed or punctured. Instead, owners are encouraged to contact their local household hazardous waste centers or municipal recycling departments to receive proper instructions on how to safely dispose of the recalled units. These centers are equipped to handle the specialized recycling protocols required for lithium-ion chemistry, ensuring that the components are processed in an environmentally responsible and safe manner.
This recall serves as a reminder of the complexities inherent in modern consumer electronics, where high-capacity batteries are essential for the functionality of portable devices. Lithium-ion technology, while highly efficient, requires rigorous quality control and safety standards. When manufacturing defects occur, the result can be hazardous, necessitating the type of large-scale intervention seen here. Bose’s coordination with the CPSC reflects a standard practice in the industry to mitigate consumer risk once a recurring manufacturing issue is identified.
As the recall process moves forward, Bose continues to update its support channels to assist customers. For those who may own multiple units or are using these systems in a professional or commercial setting, the company recommends reviewing all inventory to ensure that every battery pack is verified against the recall list. The swift identification and removal of these batteries from service remain the primary objective for both the company and federal safety officials, ensuring that the utility of the S1 Pro line can be enjoyed safely by its user base long into the future. By following the provided instructions and utilizing the replacement program, owners can eliminate the fire risk while continuing to enjoy the high-fidelity audio performance for which these portable speaker systems are known.
