Bell'O Digital headphones sound great, fit comfortably in your ear and most importantly are built to last. One word could sum up our design team: passionate. Our designers and engineers are not only avid users of headphones, but are passionate about creating products to elevate the quality of your music. Just like you, we enjoy listening to our favorite artist while on the go, exercising, or just chilling. Understanding the importance of durability, sound quality and lightweight comfort is not just our job, it's our active passion. We've used a meticulous choice of materials and quality construction that offer durability and deliver great sound performance. The proper fit is essential for noise isolation, resulting in precision acoustics and deeper bass. Because no two ears are alike we've included three sets of custom-fit earbuds for the ultimate comfort and performance. The cable was engineered to be durable, flexible, lightweight and tangle resistant. Our 24K gold-plated plug fits a 3.5mm jack and provides optimum connection and corrosion protection.
