Silicone Case for Sony WF-1000XM3 Earbuds from 3 C Electronic Store on Lazada for S$5.43 with free shipping to Singapore.

Five colors are available, Black, White, Dark Blue, Red, and Cyan. I chose black. Regardless of colors, it comes with a black carabiner.

The silicone case is 1.5mm in thickness and comes in two pieces, one for the cover and one for the body of the Sony WF-1000XM3’s charging case.

My only complaint about this case is the lack of cover for the hinge area.

There is a cut out for the USB-C charging port, but it lacks a dust cover for it.

Unlike the Silicone Case for Apple AirPods, this cover does not block the front LED.
