most earbud that I have try tend to sound `` tinny '' and very shallow . these have a more realistic depth to the sound quality . the earbud fit in you ear very comfortably , you will hardly notice they . they be well construct and I love the auto wind feature . the case even have a flip door to place the earbud in after you be finish use they . I do not think you 'll find a better quality set of earbud for any price .
