It’s been recalled as a fire hazard. See if you can get your money back first:

Brookstone announced the recall of 164,000 wireless speakers because of the risk of fire associated with their lithium-ion batteries.

The affected model is the Big Blue Party, a large indoor-outdoor speaker that was sold by major U.S. retailers and websites from December 2013 through August 2018 for about $200. Consumers should stop using the devices immediately.

Brookstone filed for Chapter 11 bankruptcy protection earlier this year, complicating the process for consumers to obtain a partial refund.
