Some Sonos first-gen Roam speakers are overheating and melting
Early Sonos Roam speakers are overheating, with enough complaints of melted charging cables, jackhammer-type noises, and even a burning plastic smell coming from affected devices forcing the company to respond.

The original Sonos Roam was launched back in 2021, though much about the portable Bluetooth and Wi-Fi-enabled speaker was known ahead of launch. One thing users weren't expecting, however, was that their charging cable and sometimes the speaker itself would melt.
Multiple Reddit posts, some dating back to 2022, detail similar issues with the first-generation Sonos Roam. Users have reported "a burnt smell coming from the speaker," and they have also complained of a "melted USB connector," among other things. Many of the social media posts contained imagery of burnt and partially melted charging cables.
Posts from Sonos' official community website also outlined the same issue, prompting the company behind the speaker to issue a response.
In a statement to Bloomberg, Sonos said that it has "closely tracked a limited number of reports involving the USB-C charging connection on some first-generation Sonos Roam speakers."
The manufacturer notes that the number of cases is "very low," and claims that "environmental conditions appear to play a role."
Even so, Sonos has taken what it calls "proactive steps" to reduce the likelihood of the issue occurring. The company's approach involves "software updates and hardware improvements." The latter of the two is especially interesting, given that the company already released a successor product in 2024. No recall has been issued for the original Sonos Roam speaker.
The statement was published comes after just months after Sonos' other apparent failures came to light. In March 2025, the company was said to have scrapped a portable streaming player that would have rivaled the Apple TV. Two months prior, Sonos' CEO left the company after eight years, all due to the botched launch of an iOS app.
