The earphone cord uses a TPE outer skin that is less likely to tangle with the inner copper wire and reduces touch noise, offering high elasticity and durability while also being easy to wear. 【Stress-Free Fit】The wired earphones use flexible silicone and a mini-size, ultra-lightweight design, so they won't hurt your ears even when worn while sleeping. They fit snugly in the ear canal, with almost no pressure on the ear canal, providing a comfortable fit! They can be used in various situations, not just when sleeping, but also for travel, study, work, commuting, and more. 【HiFi Sound Quality】The wired sleep headphones feature an integrated chamber structure equipped with a 6mm unit, reducing surrounding calipers and achieving clear mid-high frequencies, contoured bass, and premium sound that provides a sense of spaciousness, enabling a more natural audio experience and allowing for clearer output of the original sound.
