The company said the issue is happening in the original model of the portable speaker.
Sonos is having overheating issues with a "very low" number of its Roam speakers. Bloomberg reports that some users' portable Bluetooth speakers are overheating around the device's USB-C port. The company has not recalled any products as a result but it aware of the issue happening.
"We’ve closely tracked a limited number of reports involving the USB-C charging connection on some first-generation Sonos Roam speakers," Sonos said in a statement shared with Engadget. "While the overall incidence rate is very low, and environmental conditions appear to play a role, we’ve taken several proactive steps to even further reduce the likelihood of this issue, including software updates and accessory improvements."
