ACEFIT NEO Open Ear Headphones Wireless Bluetooth 5.3 / 14.8mm Dynamic Driver / Call Noise Reduction / Approximately 30 Hours of Continuous Playback / Doesn't Block Ears / Sound Leakage Prevention / Wireless Charging Air Conduction Compatible with iPhone/Android Sports/Riding/Town/Subway, etc. White 【Original Design -- Wireless Earphones That Don't Need to Be Hung on the Ear & Don't Block the Ears】ACEFIT NEO is a new open-ear headphone designed to provide a natural sound experience similar to biological hearing. Primarily through air conduction, it transmits sound directly to the eardrum and through the ear canal, as if a surround sound system is built into the ear. At the same time, these earphones prioritize health and comfort, abandoning the constraints of traditional in-ear and ear-hook styles, and adopting an innovative ear support design that eliminates contact between the earplugs and the inner ear, ensuring air circulation. This reduces the growth of ear canal bacteria and keeps the ears dry, saying goodbye to the risk of stuffiness and bacterial infection caused by long-term wear. 【Super Large Touch Area & Silicone Ear Hooks & Comfortable and Stable Fit】The super-large touch area design allows you to easily control operations such as music playback, volume adjustment, and answering calls with a smart touch, eliminating the need to fumble for the touch position. The earphones themselves weigh only 8g and do not put a burden on the wearer. In addition, by combining our unique patented silicone ear hooks, we address the common weaknesses of sound sources and open headphones, ensuring a more secure fit. The ergonomic design provides an exquisite fit that you'll forget you're wearing them. We provide three sizes of patented silicone ear hooks: S/M/L, which are perfectly compatible with various ear types, and whether you have a small face or are an average man, you can find the perfect size for yourself. While providing a comfortable fit, they are also stable and unlikely to fall out, so you can immerse yourself in the world of music all day long.
