With a level of aesthetics that’s comparable to seeing the Yin and Yang elements lock in to form a complete circle, the Koishi TWS Earbuds by Sjoerd Ramaker focus on visual gestalt. The headphones come with a square case that has no lid to begin with. Instead, the headphones ARE a part of the case as they snap conveniently into the sides to complete the soft, rounded square’s form.

Named Koishi, after the Japanese word for Pebble, the TWS Earphones come with a soft, pebble-inspired form that’s beautiful to look at, comfortable to store in pockets, and can even be stacked one above another as Zen Stones. They come in three stone-inspired colors, and even sport a slightly mottled stone texture. Running right through the case is a light strip that helps let you know when the earbuds are charging, or when they’re low on charge. However, it also visually guides you to instinctively know where the earphones are, so you can glance at the case and pull the earbuds out without fiddling to find them. I personally love how calming they look, and how satisfying it feels to see the earphones snap right into the case, creating a flush, complete form!
