The sound profile of the Beam3S can be categorized as a "modern sound": clear, transparent, with an inclination towards acoustic presentation and rich musicality. Both vocals and instruments are articulate, but compared to traditional sound signatures, it leans towards being brighter and more robust. Its low-frequency extension is outstanding; it seems capable of reproducing the deepest sub-frequencies, possibly reaching below 30Hz, allowing for clear differentiation even in the lower registers. This characteristic could be attributed to its larger driver and internal structure, which contribute to excellent low-frequency reproduction. The bass is moderate in quantity, solid, concise, and sets a favorable mood for music, creating a immersive atmosphere. The standout feature of the Beam3S is its ability to shine in reproducing large ensembles. Areas that are typically prone to blurring, muddiness, or lack of dynamics are revitalized and opened up, resulting in a performance that closely resembles a live concert experience.
