My IEMs do not have much bass, what is going on?

  • Typically, this is due to fit issues as the eartip does not form a full and complete seal within your ear canal.

    Gently press the earphones deeper into your ear and see if you hear more bass. Try tilting the earphones at different angles and/or swap to a variety of eartip sizes. With a good fit, you should perceive environmental sounds around you as muffled.

    Symphonium Audio IEMs are designed with a deep fit in mind for the best audio experience.
