ooopusX Op.22 In-Ear Monitors 2DD+2BA with Tuning Dial

The ooopusX Op.22 is a high-resolution in-ear monitor combining two dynamic drivers and two balanced armatures with an adjustable electronic tuning dial for versatile sound profiles.

The Op.22 blends precision engineering and user-adjustable voicing to suit listeners who want studio-grade detail and a warm, musical character in one compact IEM. Built with a silicone composite carbon-fiber diaphragm, oxygen-free cable, and a refined stepped nozzle for better fit, these monitors are tuned to cover 10 Hz–40 kHz with low distortion and high sensitivity.

How does the Op.22 create two distinct sound signatures?

Its tuning dial controls an independent dual-channel electronic crossover that switches between sound signatures instantly. Rather than using passive filters, the Op.22 relies on active crossover routing for clearer separation between drivers and quicker, more predictable changes in tonal balance.

• Independent dual-channel electronic crossover for precise voicing
• Two selectable modes to emphasize warmth or detail
• Immediate switching without mechanical reconfiguration
• Optimized crossover reduces phase issues between drivers

What makes the driver configuration special?

The Op.22 pairs two custom dynamic drivers with two balanced armatures in a coaxial layout to unify timing and imaging. Dynamic drivers provide rich low-end and body, while balanced armatures supply refined and extended highs, tuned together to maintain coherence across the frequency range.

• Coaxial dual dynamic drivers for synchronized diaphragm movement
• Balanced armatures tuned for smooth high-frequency performance
• FEA-optimized magnetic circuit to minimize phase interference
• Acoustic structure engineered for natural roll-off and clarity

How does the Op.22 perform in real listening situations?

With a low 22 Ω impedance and high 124 dB sensitivity, the Op.22 is easy to drive from phones, portable players, and desktop sources while delivering dynamic impact and detail. Total harmonic distortion is kept under 1% at 1 kHz, preserving clarity even at elevated volumes.

• 10–40 kHz frequency response for extended treble and low bass presence
• 22 Ω impedance suits both portable and desktop devices
• High sensitivity yields robust volume from modest sources
• <1% THD keeps sound clean and undistorted

What design and comfort features were prioritized?

The Op.22 continues the Op-series focus on ergonomics with a refined stepped nozzle that improves seal and long-term comfort. The included oxygen-free 0.78 2‑pin cable and robust 3.5mm termination provide reliable connectivity and low signal loss for daily use.

• Stepped nozzle design for improved fit and stability
• Silicone composite carbon-fiber diaphragm for controlled response
• Oxygen-free cable minimizes corrosion and preserves signal integrity
• 0.78 mm 2‑pin connectors allow cable upgrades or replacement

Who is this for: The ooopusX Op.22 suits discerning listeners, portable-audio enthusiasts, and pro monitoring users who want flexible voicing in a single IEM. If you seek a warm yet detailed presentation, driver-level engineering to reduce phase issues, and an easy-to-drive monitor with adjustable tuning, the Op.22 is designed to meet those needs without extra amplification.
