The included wired remote control allows you to adjust the volume and skip tracks with your fingertips, without having to take out your device, delivering a truly smart music experience. "Comfortable design that doesn't block your ears" Employs bone conduction technology for zero burden on your ears. Simply place it under your pillow to clearly listen to music and ASMR. Unlike conventional earphones, you can enjoy a natural music experience without pressure, even when sleeping on your side. "Enhanced sleep support features" Includes 26 types of natural sounds with relaxing effects, such as the sound of waves, a bonfire, and rain.

"High Quality & After-Sales Service" Our store offers high-quality bath polishers. You can use them for a long time, so please rest assured. If you have any initial defects or any unclear points, please contact us via "Order History" → Corresponding order → "Ask a question." We aim to provide after-sales service that satisfies our customers. "Attenuation of High-Frequency Audio" This product employs solid conduction technology. By directly transmitting sound waves through the molecular structure of the pillow, it achieves a previously unheard-of private listening experience. ※ Just as sunlight softens when passing through a shoji screen, high-frequency sounds naturally attenuate with solid conduction. This is an essential technical feature for achieving non-leakage sound. This is a currently unavoidable principle of physics.
