Some devices may claim to produce neutral sounds. This implies that the headphones do not make any changes in the sound, that they are recreated just as they were received by the device. Most people, however, do not opt for these earphones for casual use. Some may prefer earphones that produce a stronger bass, others might opt for ones where instruments are stronger than lyrics. For those that wish to listen to classical music without any deviation from the original, neutral earphones are the way to go.
