These headphones make great bass and treble. The classic jack allows them instead of that of a smartphone or MP3 player and it is a sacred quality difference. I also serve to control the sound on an HD camcorder and again this is much better. Other qualities are round flexible ear, the small size, discretion and speed of implementation. I could never keep more than a minute conventional headphones because they are constantly falling. These remain in place and are still well oriented. It is unbeatable on the price-plan.
