If you own a Bose S1 Pro or S1 Pro+, we have some good news and bad news. The good news: the speaker himself is fine. The bad news: the battery pack inside may be less than good. Bose and the US Consumer Product Safety Commission (CPSC) announced a recall on Thursday that covers nearly 635,000 lithium-ion battery packs in the US, as well as about 35,400 in Canada.
The affected packs may overheat and ignite, risking fire and burns, so stop using yours immediately if affected. Bose has received seven reports of batteries melting, smoking or catching fire. Among them were six cases of property damage. Fortunately, no injuries were reported.
The S1 Pro and S1 Pro+ are Bose’s portable PA speakers, designed for parties, gigs and the like. The speakers have a built-in mixer, support Bluetooth streaming and can go mobile with the removable battery pack. The S1 Pro+ supports a wireless mic and instrument transmitter, a separate $159 purchase.
The affected packages were sold from December 2017 to July 2026 at Bose, Best Buy, Amazon, Walmart and other retailers. The battery packs came in the box with many of the speaker units, which cost about $700, and were available separately for between $100 and $160.
Not every battery pack is recalled. To find out if yours is, you need to remove the battery, find its 17-digit serial number, and check it against the recalled batches. When the battery serial starts with 083723, 078352, 084105, 078591, 078592, 084106 or 086409You may want to sign up for a free replacement on Bose’s recall page.
