I took a try on Cowin's 30% off promo. I received free shipping. That was a good deal. Compared to other brands, these are really small and lightweight. Other active/sports earbuds are bulky in the ear can cause discomfort before the battery dies. These sleek earbuds have a more comfortable smaller form factor. I also like the sound modes. You can have ANC off when it is quiet like inside the house; ANC on when you are in studying, public or working around fans, motors, power tools running; and the other mode, which lets you hear and amplify ambient settings like when you need to be alert of your surroundings like walking, running, or listening out for visitors. Another thing I like is the USB cable is USB-C, which is the same for my cell. This makes it easy to plug in the cable and have one less cable to carry. This will mainly be used while I am studying/homework, to accompany ear protection in loud environments, and working out/fitness.
