Bose is recalling roughly 634,759 lithium-ion battery packs used in its S1 Pro and S1 Pro+ portable Bluetooth speaker systems. The U.S. Consumer Product Safety Commission says the packs can overheat and ignite, and owners should stop using them right away.
Why the battery packs pose a fire risk
The recall covers battery packs made for the S1 Pro and S1 Pro+ speaker systems, which the company sold between December 2017 and July 2026. Regulators say the lithium-ion cells in these packs can overheat and catch fire, creating a risk of burn injuries and property damage. The CPSC reports that the manufacturer has received seven reports of packs melting, producing smoke or catching fire. Six of those reports involved property damage, and no injuries have been reported so far.
Which units are affected
Only battery packs with serial numbers beginning with 083723, 078352, 084105, 078591, 078592, 084106, or 086409 are included in the recall. Those packs were sold separately for between $100 and $160, and the complete speaker systems sold with them for $700. Buyers purchased the packs at Bose, Best Buy and other retail stores, as well as online through Amazon.com, Bose.com, BestBuy.com, Walmart.com and other websites.
What owners should do now
Owners should check the serial number on the battery pack installed in their S1 Pro or S1 Pro+ speaker and stop using it if it matches the listed numbers. The CPSC advises removing the recalled pack from the speaker and not charging or operating it in the meantime. Consumers with questions about a refund, replacement or the recall process can call Bose at 800-278-1083 or visit the company's website for details.
