I believe everyone has the experience of wearing uncomfortable headphones. No matter how they claim their noise-cancellation function is strong, their heavy bass is great, their shape is unique, or other features we like or dislike, the comfort level when wearing headphones is still our first consideration when purchasing headphones. And this infinitely creative DIY sock headphone, which emerges from the ordinary, becomes the best friend of our ears. Although the sound quality may slightly differ after passing through layers of cotton, compared to other headphones that are extremely painful to wear, it allows our ears to enjoy the music transmitted from the headphones in the most comfortable way.
