The Triton, with its tribrid driver system with a powerful W9+ subwoofer, BA drivers, and Bone Conduction, deliver a fun and smooth sound signature.
The W9+ subwoofer brings impressive bass power for deeper, more textured bass with natural decay. The balanced armatures layered on top bring clarity and definition to the mids and treble, giving instruments and vocals weight while still preserving detail.
The slightly larger housing allows for better driver placement and airflow, which helps create a wider, more holographic soundstage. The result is a sound that feels immersive and full-bodied, perfect for listeners who want to feel like they're part of the performance.
The THIEAUDIO Monarch MKII delivers a balanced yet musical sound that leans toward reference tuning with a touch of warmth and depth.
The low end hits with authority thanks to its 10mm dynamic driver, delivering tight, extended, and textured bass notes. Mids are clean and natural, offering a smooth tonality that gives vocals and instruments a lifelike presence without sounding too forward. Treble is airy and extended, courtesy of the dual EST drivers, offering crisp detail and micro-nuance without harshness.
Overall, the Monarch MKII presents a refined “studio-grade” sound that balances technical precision with musical engagement, making it a versatile IEM for listening to genres from acoustic to electronic.
At $1,799, the Triton features cutting-edge driver technology, reinforced resin housing, and premium aesthetics.
