Yibracki Heavy-Duty Speaker Wall Mount and Ceiling Speaker Mount for Sonos Era 100 Wireless Speaker Mount,Tilt & Swivel Adjustable Mount or Sonos Era 100 Speaker with Hardware Kit - 2 Pack, Black

I needed a ceiling mount. I looked at a three different wall mounts to see if any might work but they did not look secure for ceiling mounting. Then I saw these. I was a little hesitant, but they work very well after I tossed the included screws in the trash. I did end up using one screw (for the tilt-swivel) because I did not have an equivalent handy. These would work well as a wall mount too.The detractors are too picky. The mount is well designed and fairly easy to install. The screws are trash but that is easy to fix. Overall, they are better than any of the wall mounts I checked out.

I installed two under kitchen cabinets. It took a bit if measuring and maneuvering to get them positioned just right, but once I did, they held my Sonos speakers great! Very secure they look fantastic

In the picture you can see that one of the screw holes is off centre. On top of that, they are also the wrong size. The rest of the product seems quite sturdy.

I have a sonos arc soundbar with sub in my kitchen and really wanted era 100s for surrounds but didn't want them sitting on the counter so it's easier to clean. However, my backslash is solid stone so I couldn't drill a mount into the wall. These worked great if I hung the speakers upside down below the cabinets. 👍

Worked well for ceiling mount.
