Featuring a bespoke 50mm Ceramic-Metal High-Flux Magnetic Long-Stroke Dynamic Driver (CMHFMLS-DD) tuned by Zeos, the Eris delivers expansive sound staging, deep bass, and distortion-free performance. Its semi-closed back design with an M-type pressure relief system balances sound isolation and openness, making it ideal for gaming, music production, and immersive listening. \u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eLatest generation dynamic driver\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003eThe Eris is designed around HarmonicDyne’s latest generation of Ceramic-Metal High-Flux Magnetic Long-Stroke Dynamic Driver (CMHFMLS-DD). Featuring a 50mm ceramic-metal fusion diaphragm, this new dynamic driver is extremely responsive and delivers some of the best sound HarmonicDyne has to offer. Combining the tensile strength of micron-thin metal sheets with the rigidity of ceramic layering, the CMHFMLS diaphragm achieves greater rigidity than typical membrane-based diaphragms while offering more resolution, extremely wide staging, and powerful low end reproduction without noticeable distortion. \u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eSemi-closed back design\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003eThe Eris features HarmonicDyne’s M-type pressure relief system that passively ventilates the acoustic cavity. This system combines some of the benefits of closed back headphones, such as better sound isolation (roughly -5db), with passive airflow to achieve an open-sounding or “big stage” experience. Balancing\/tuning the internal pressure within the acoustic cavity allows for a life-like sound staging experience and substantial bass control down to the sub-bass frequencies.\u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eComfort, build, looks\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003eZeos put extra care into making sure the Eris was as comfortable as possible for long listening sessions. The pads are crafted out of softer materials and feature a unique Light Blue micro-suede fabric and vegan-leather design in order to achieve the ideal level of airflow, isolation, and comfort in both warm and cool environments. The headband and frame were constructed with resilient materials including injection-molded plastic, glass, aluminum, and were put through rigorous physical testing. The Eris weighs 320g (without cable), making it lightweight enough to use for hours while walking, gaming, yoga and other physical activities. \u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eThe balanced cable\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003e\u003cspan\u003eThe Eris comes standard with a 4.4mm custom balanced cable (3.5mm Dual Entry) made from customized solder-tuned single crystal copper wires. More costly to manufacture than traditional stock cables, this upgraded cable allows for worry-free connection from any source gear to Eris for the best listening experience right out of the box, and can be swapped out for other custom 3.5mm dual termination cables in the future, ensuring customizability and preference are in your hands.\u003c\/span\u003e\u003c\/p\u003e\n \u003ch2 dir=\"ltr\"\u003e\u003cstrong\u003eTwo listening experiences\u003c\/strong\u003e\u003c\/h2\u003e\n \u003cp dir=\"ltr\"\u003eDue to the fully-symmetrical design of the Eris, it’s actually possible to reverse the cable left and right and use the headphone backwards to achieve a separate and unique listening experience. Moving the angled driver to the rear of the cup takes the focus off of detail retrieval and applies an even greater sound stage presentation, while keeping imaging and overall tonality very similar. \u003c\/p\u003e\n \u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eProduct highlights\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eDesigned with Zeos from Z Reviews\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eNext-gen drivers: 50mm ceramic-metal diaphragm for wide staging, deep bass, and minimal distortion\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eSemi-closed design: Balances isolation (-5db) with open-stage sound\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eSoft micro-suede pads and lightweight (320g) build for hours of use\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eBalanced 4.4mm solder-tuned copper cable\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003eTwo listening modes: detail-retrieval or soundstage \u003c\/p\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3 dir=\"ltr\"\u003e\u003cstrong\u003eSpecs\u003c\/strong\u003e\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eDrivers: Ф50mm Dynamic Driver\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eAcoustic Architecture: Semi-closed (4 Vent)\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eInput impedance: 32ohm\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eFrequency Response: 10-70KHz(Free Field)\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003eSensitivity: 118dB\/Vrms\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eTHD: \u0026lt;0.2%\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eCables: 4.4mm Balanced Cable\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eEar-pads: Micro-Suede Fabric + Vegan Leather\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eDimensions: 210*175*105(mm)\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eWeight: Approx. 320g (without cable)\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eCable Length: 1.5M\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003ch3 dir=\"ltr\"\u003eWhat’s included\u003c\/h3\u003e\n \u003cul\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003e1 x HarmonicDyne x Z Reviews: Eris\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003cli dir=\"ltr\" aria-level=\"1\"\u003e\n \u003cp dir=\"ltr\" role=\"presentation\"\u003e\u003cspan\u003eUser Manual\u003c\/span\u003e\u003c\/p\u003e\n \u003c\/li\u003e\n \u003c\/ul\u003e\n \u003cp dir=\"ltr\"\u003e\u003cspan\u003eNOTICE: Eris can take up to 50 hours of Burn-in for the driver and ~10 Hours of Break-in for the Pads to achieve its final sound.
