🎶　2025 New model: Small! light! Good sound! The popular wireless earphone "COTSUBU", which has shipped over 300,000 units in total, has a new color.The sound quality is even clearer, and a new feature, multipoint, has been added. 🎶 Ultra-compact and ultra-lightweight: The earphones are the smallest and lightest in the series, weighing approximately 3.5g on each side.It's so light and comfortable that you'll forget you're wearing it. Since it fits perfectly in any ear, the earphones will not easily pop out of your ears, and you won't have to touch the earphones when putting on or taking off the mask and cause them to fall out.
