Thank you for viewing. I accidentally bought one too many, so I'm offering it at a special price. Bluetooth 5.3 Codec: AAC Sleeping Wireless Bluetooth Headphones: Mini, Small Unique mini ultra-small design, unobtrusive fit, and excellent sound quality, bringing you unparalleled comfortable sleep and music enjoyment. Product Description Mini Ultra-Small Design: These earphones adopt a very compact body design that easily fits the contours of the ear. With no protrusions, they fit snugly in the ear, allowing you to enjoy music while maintaining a comfortable experience for extended periods, especially when sleeping. Unlike traditional open-ear earphones, they adopt a unique method of wearing on the outside of the ear, without needing to connect to the ear canal, effectively avoiding pressure on the ear canal and reducing the risk of bacterial growth. Suitable for long-term wear, especially for sleep. High-Resolution Sound Quality Experience: Despite their small size, the sound quality is uncompromising. Adopting advanced audio decoding technology, it guarantees clear and full sound quality, whether it's soft sleep music or passionate dynamic melodies, allowing you to enjoy a high-quality musical feast in your dreams. Intelligent Noise Reduction: The built-in intelligent noise reduction chip effectively filters external noise, creating a quieter sleep environment. It can easily block out urban noise and nighttime disturbances, allowing you to sleep peacefully.
