The Horizon delivers an extreme naturalness and life-likeness in your music thanks to a smooth upper treble extension. Utilizing two planar drivers to effectively extend the upper trebles to 35kHz, the Horizon allows you to discover a new realism in your audio. \n\n\n\n\nTribrid Configuration\nThe Horizon utilizes a single 10mm biodynamic driver to power a thumpy and engaging bass response. The midrange feels smooth and has an analog texture thanks to two custom ported Knowles 30262-163 balanced armature drivers. A dual custom composite planar drivers are dedicated to the treble and are specifically designed to enhance the 20 to 35kHZ ultra-treble range. \n\n\n\n\n\nButtery Treble Extension\nPrevious attempts by the IEM industry to enhance the treble response has always resulted in harshness and peakyness in the treble range. By designing custom planar drivers for the upper treble, we have achieved an almost completely linear treble extension that does not deviate more than 4dB across the entire 20 to 35kHz frequency range. This means you can appreciate the expansive soundstage and air that brings your music to life, without any unnatural shrillness or harshness. \n\n\n\n\n\nNatural Tonal Balance\nThe Horizon has been tuned to feel natural and comfortable. Compared to our other models, the Horizon features a smoother transition across the entire frequency spectrum to provide a more music experience. The sub-bass kicks are tight, but the bass roll-off is more lenient, allowing more bass-guitar presence to tie into the low-mids. The midrange is flat, but thanks to a more relaxed crossover with the bass, instruments and vocals retain a little more warmth. The treble is carefully calculated to balance the entire tonal curvature, with the upper trebles being smoother to accommodate the treble extension. \n\n\n\n\n\nHandcrafted Quality\nEach Horizon unit is handcrafted.
