EASY TO USE - Our sleep mask headphones are incredibly easy to use. They pair quickly and easily with any smartphone or tablet device within 33 feet. The controls are located on the side of the mask, making it easy to adjust the volume, skip tracks, and answer phone calls without having to remove the mask. WIRELESS AND VERSATILE - Our sleep mask headphones are wireless, allowing you to use them anywhere, anytime. The central panel and ultra-thin sleeping headphones feature a silicone cover that is soft and gentle on the ears, so you won't feel any hard panels or earphones. The noise-canceling feature works well in noisy environments, making them the perfect eye mask headphones for air travel, car travel, yoga, noontime snooze, audio books, meditation, and even kids' bedtime reading. COMFORTABLE DESIGN WITH NO PRESSURE ON THE EYES - The sleep mask is made of premium memory foam with a smooth ice silk lining that is lightweight, skin-friendly, and breathable. This unique design allows you to release facial stress and quickly fall asleep, without feeling like you're wearing a bulky mask. You'll hardly feel anything when you wear it, and you'll wake up feeling refreshed and energized. QUICK CHARGING & LONG BATTERY LIFE - Our sleep mask headphones feature a powerful upgraded battery chip that only needs to be charged for 1-2 hours to provide over 14 hours of playing time. This means that you can wear them all night and never have to worry about running out of battery. Additionally, if the battery does run out while you're sleeping, the mask won't beep and wake you up, ensuring a peaceful night's rest. SUPERIOR HD STEREO SOUND QUALITY - The MUSICOZY sleep headphones are the best on the market when it comes to sound quality. Our latest V5.2 technology and high-quality components produce a superior listening experience, with deep bass and crystal clear treble that will help you relax and sleep soundly.
