Well, comfort comes in various aspects. The right headphone should have an ergonomic design. We mean, it should align itself with the contours of the ear so that you do not strain while wearing it. Also, it should produce the perfect sound quality that will not irritate your ears. Some models have an adjustable headband. Such a design makes it flexible as it will fit on every size of your head rightly. Also, it should have some soft padding that is even to enhance the wearing comfort. The materials used for padding should be breathable and soft.
