FiiO FD15 Review – Best Single DD IEM of the Year

The FiiO FD15 is a good-looking and well-constructed IEM that has a sound signature offering an impressively versatile tonality with a natural, inviting midrange and dynamic bass response. A general appeal that does well with almost any music genre. These IEMs sound as good as they look. FiiO FD15 delivers exactly what it promises, a true flagship dynamic driver IEM for a relatively good price. I think it’s the best single DD IEM of the year.
