In the past few days,videos of people having sex owners of Apple's HomePod have found that the device leaves visible white rings on their furniture. But it turns out the HomePod isn't the only speaker that can damage furniture.

A reviewer from Tom's Guidefound Thursday that the Sonos One speaker left distinctive white marks on their wooden shelf. A week after the reviewer moved the speaker from the shelf, its mark had faded, but still remained.

The Sonos One is mounted on four feet, rather than a complete ring base like the HomePod's. The photo from Tom's Guide shows markings from the Sonos One's feet that outline the speaker's box shape, but aren't as pronounced as the ring the HomePod leaves.

Apple has attributed the rings left by Apple's HomePod to "oils diffusing between the silicon base and the table surface." Apple suggests cleaning the affected surface with the manufacturer's suggested oiling method.

If the marks are anything like the HomePod's, they may never fade completely. You may need to sand and refinish your surface to bring it back to normal -- and to move your speaker, or place it on a coaster, if you want to avoid such damage in the future.

Alexa's not off the hook. Twitter user Ted Landau that an Amazon Echo Dot created a similar mark on an oiled wood surface.

The devices only appear to damage oiled wood surfaces, but this could still be a problem for many customers who want to display their smart speakers in nicer areas of their homes. Sonos One, HomePod, and Echo owners will have to decide whether to move their devices or embrace the rings. In the meantime, it might be time to shop for coasters.

A Sonos spokesperson told Mashable that "This is the first time we are hearing about this. We’re investigating.”
