--------------------------------------------------- 【Voltage Compatibility】 Our products are selected to support international voltage ranges (e.g. 100–240V). However, please make sure your local voltage is compatible before use, as incorrect voltage may still cause malfunction.

【Plug Type】 Our products use Japanese plug types (A or B type). Please use a conversion adapter if necessary.

【Important Note on Transformers and Adapters】 A transformer adjusts voltage to match your device’s requirements. A conversion adapter only changes the plug shape and does not adjust voltage. Using only a conversion adapter without a transformer may result in damage to the product.

【Liability】 We are not responsible for malfunctions or damages caused by improper use, such as operating the product without appropriate voltage or equipment. --------------------------------------------------- [Comfortable and Secure Fit, No Ear Pain] Our wireless sleep headphones are extremely small and lightweight, weighing just 2.7 grams per ear. Made from extremely soft materials and ergonomically designed for sleep, they are extremely secure and won't put pressure on your ears, even when sleeping on your side. We offer three sizes of ear cups and tips (S/M/L) to ensure the sleep headphones fit properly and provide a fatigue-free listening experience. Efficient Sound Isolation: Our sleeping earphones fit deep into your ears for a comfortable fit and excellent sound isolation. They eliminate sound leakage and effectively block out external noise, achieving up to 24 decibels of noise reduction. Enjoy music comfortably while you sleep without being disturbed by surrounding noise or family snoring, resulting in a better sleep experience. [Super Long Lifespan] Our sleep earbuds provide up to 4.5 hours of wireless playback on a single charge, and with the included charging case, you can extend that to 27 hours. Even if you're out and about all day, you don't have to worry about battery life. If the battery runs out, simply use the included USB-C cable to fully charge it in just 2 hours. [Bluetooth 5.3, One-Step Connection] Our Bluetooth sleep earbuds require no app. After pairing with your smartphone for the first time, they automatically connect when you remove them from the charging case. You can use each earbud independently and easily switch between single and dual ear modes. Bluetooth 5.3 technology provides a more stable signal connection with fewer skips and interruptions, allowing you to listen to music or continue talking without dropped calls. [Simple and Convenient Operation] Our Bluetooth wireless sleeping headphones support smart touch, providing convenient operations such as pausing/playing music, adjusting volume, previous/next song, rejecting calls, hanging up calls, and more. Enjoy calls and music in a variety of situations, including driving, commuting, working, and exercising. We offer a one-year warranty, and your order number serves as your warranty card.
