The ATH-SQ1TW earbuds are Bluetooth 5.0 compatible, delivering high-quality audio in a compact, lightweight design. The compact body is unobtrusive while keeping the TWS earbuds from coming loose or falling out. They provide up to 6.5 hours of continuous use on a full charge or 19.5 hours with both the earbuds and charging case completely charged. The built-in microphone captures ambient sounds with the hear-through function, ensuring users remain aware of their surroundings even while listening to music or making calls.
