Meet the smallest wireless earbuds in the world. The Swedish company Earin introduced the compact A-3, a pair of true wireless earplugs with an open design and no earplugs. The result is a more comfortable listening experience. The headset can sit in the bowl of the user’s ear without the need for silicone earplugs that can be inserted directly into the ear canal. This also means that they are somewhat scattered, rather than protruding from the top of the head. They also have a custom 14.3mm dynamic driver, an intuitive touch interface on the earbuds, which can quickly answer calls or play music, sweat resistance, waterproof and dustproof, and an adaptive algorithm that can monitor and eliminate background noise in real-time. Each time they are charged, they can play for up to 5 hours, and when the aluminum charging case is used, they can play for a total of 30 hours. Another cool feature is that they don’t have designated “right” or “left” earbuds, so it’s easy to remove them from the charging case and start using them.
