Know before you buy
The IMPACT2 system uses an isobaric dual dynamic driver design to improve sub-bass texture and impact. It provides a deeper, more tactile bass response without bleeding into or muddying the midrange frequencies.
The Oracle MKIII balances professional-grade neutrality with a more engaging, natural tuning. While it maintains the clear, accurate mids required for studio work, it adds a refined musicality that makes it suitable for both critical listening and casual enjoyment.
With an impedance of 13Ω and a sensitivity of 99dB, these IEMs are relatively easy to drive. While they will work with most standard devices, using a high-quality DAC or amplifier will help you get the most out of the EST tweeters and the complex crossover system.
The product includes a modular cable system that features 2-pin 0.78mm connectors. It comes with interchangeable 2.5mm, 3.5mm, and 4.4mm termination plugs, allowing you to easily switch between balanced and unbalanced sources.
The 4-way crossover ensures that each driver handles only the frequencies it is best suited for, which prevents distortion and overlap. Combined with the three independent sound bores, this results in superior instrument separation and precise imaging.
The Oracle MKIII features a universal fit design engineered for ergonomics. While fit is subjective, the housing is shaped to sit securely in the ear, making it generally comfortable for extended periods of use.
