Easy to drive yet capable of scaling with serious equipment, it’s a versatile headphone that’s great for newcomers and veterans alike. \u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003eFeatherlight and easy to drive\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eThe Horizon is light on your head and easy to drive. At just 32Ω impedance and 109dB\/Vrms sensitivity, it doesn’t need a dedicated amp—though it scales with one. You can plug it into a laptop, portable DAC, or a serious desktop rig and still hear its low-distortion, full-range performance. \u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003eA new kind of dynamic driver\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eAfter two years of design and testing, the Moondrop’s 50mm ULT dynamic driver is tuned for linearity, bandwidth, and low distortion. Expect wide dynamic range, smooth highs, punchy bass, and a balanced sound that keeps you locked in. \u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003ePowerful magnets, precise motion\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eThe driver’s dual internal-external composite magnetic circuit uses two N55 neodymium magnets to reach a peak flux density of 1.85T—unusually high for a headphone of this type. More magnetic flux means better control of the diaphragm’s motion and more energy efficiency, translating to clean transients and a more effortless sound.\u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003eTitanium meets liquid silica gel\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eThe diaphragm uses a titanium-plated PEN polymer dome combined with a double-layer liquid silica gel suspension. This hybrid approach improves rigidity, damping, and reliability, keeping treble extension crisp while allowing for long, low-frequency strokes without breakup. The liquid silica gel suspension also handles larger amplitudes with stability.\u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003eAngled for your ears\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eInside the cups, the driver sits at an intentional angle to better align with your ears’ natural shape. This design helps sound waves reach your ear from the front at a more realistic angle, creating a wider and more immersive soundstage with natural diffusion and better timbre.\u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003eClean and calm sound\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eThe Horizon’s frequency response follows Moondrop’s VDSF target, with a relaxed and even-handed tuning. The sub-bass reaches down to 80Hz free-field, rare for an open dynamic driver. Highs are smooth and detailed, and the mids remain uncolored. Harmonic distortion sits below 0.1% at 1kHz, so fine details in your music come through without harshness or smearing.\u003c\/div\u003e\n \u003ch2\u003e\u003cstrong\u003eCables your way\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cdiv\u003eThe dual 3.5mm connectors make cable swapping straightforward. The Horizon comes with both a 3.5mm single-ended and a 4.4mm balanced cable in the box, so you can pair it with whatever source you prefer without hunting for adapters.\u003cbr\u003e\u003cbr\u003e\n \u003c\/div\u003e\n \u003ch3\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cdiv\u003e\n \u003cul\u003e\n \u003cli\u003e\n \u003cp\u003eFeatherlight build for long sessions\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eEasy to drive with high sensitivity and low impedance\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eNewly developed 50mm ULT dynamic driver\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eDual N55 neodymium magnets delivering 1.85T flux density\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eTitanium-plated PEN dome with double-layer liquid silica gel suspension\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eAngled driver design for better ear coupling and wider soundstage\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eUltra-low harmonic distortion (\u0026lt;0.1% at 1kHz, 94dB)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eBalanced, relaxed sound with sub-bass extension\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eDual 3.5mm connectors with both 3.5mm and 4.4mm cables included\u003c\/p\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/div\u003e\n \u003ch3\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cdiv\u003e\n \u003cul\u003e\n \u003cli\u003e\n \u003cp\u003eModel: Horizon Professional 50mm dynamic driver over-ear headphone\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eDriver: 50mm ULT dynamic driver\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eImpedance: 32Ω ±15% (@1kHz)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eFrequency response: 20Hz–34kHz (IEC61094, free field)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eEffective frequency range: 20Hz–20kHz (IEC60318-4, -3dB)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eSensitivity: 109dB\/Vrms (@1kHz)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eTotal harmonic distortion: ≤0.1% (@1kHz, 94dB)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003ePlugs: 3.5mm single-ended and 4.4mm balanced\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eConnectors: dual 3.5mm headphone connectors\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eDesigned, developed, and made by Moondrop Co.\u003c\/p\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/div\u003e\n \u003ch3\u003e\u003cstrong\u003eWhat’s included\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cdiv\u003e\n \u003cul\u003e\n \u003cli\u003e\n \u003cp\u003eHorizon headphones\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eCable (3.5mm and 4.4mm)\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eAnime card\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eManual\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eCertificates\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n \u003cp\u003eService card\u003c\/p\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003c\/div\u003e","brand":"Moondrop","offers":[{"title":"Open Box - Like New","offer_id":46866157240495,"sku":"APS-AC-1087-1-LN","price":160.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0734\/6415\/2239\/files\/apos-audio-moondrop-headphone-moondrop-horizon-50mm-dynamic-driver-open-back-headphones-apos-certified-open-box-like-new-1233038956.jpg?v=1777715931","url":"https:\/\/freshized.com\/products\/apos-certified-moondrop-horizon-50mm-dynamic-driver-open-back-headphones","provider":"Freshized","version":"1.0","type":"link"}
