The Shure 315 are disappointing for neutral sound. They have an even mid-range but have underemphasized bass and treble ranges. As a result, mixes lack thump and rumble while vocals and lead instruments are veiled. Sibilants like cymbals are also very dull. They have a poor soundstage due to their closed-back in-ear design, meaning they won't be the ideal headphones for neutral listeners.
