Precise Directional Audio & Sound Leakage Prevention
The earbuds utilize advanced directional sound transmission to deliver audio directly to your ears, minimizing sound leakage. This ensures a private listening experience without disturbing others nearby, even with the open-ear design. Dual Reverse Sound Wave Cancellation technology further enhances sound leakage prevention by up to 98%.
