This unique product combines the best of both worlds – headphones and an eye mask, to give you the perfect way to relax and fall asleep. The thin and soft elastic material is comfortable to wear for extended periods, while the built-in speakers provide high-quality sound that will help you drift off to sleep. Additionally, the wireless design means there are no cords to get tangled up in, and the Bluetooth connectivity means you can use it with any compatible device. Finally, the built-in battery provides up to 10 hours of music playback on a single charge, so you can use it all night long.
