SENDY AUDIO / Apollo PRO

＜＜August 2026 New Product！＞＞The "Apollo PRO" is a fully updated open-back headphone featuring a state-of-the-art 78mm planar magnetic driver with a nanoscale composite diaphragm and utilizing zebrawood, achieving a balance of reduced weight and enhanced sound quality.

■ [Where Warmth Meets Precision] An open-back headphone featuring a next-generation planar magnetic driver—fully updated to achieve both reduced weight and superior sound quality.
・ The "Apollo PRO" is an open-back headphone with wood housings, fully updated from the previous Apollo model to offer both lighter weight and enhanced audio performance suitable for monitoring applications. It utilizes a state-of-the-art planar magnetic driver featuring a nanoscale composite diaphragm, with the driver diameter expanded to 78mm. An innovative sandwich structure—incorporating a machined magnetic layer less than 800 nanometers thick—improves response speed and resolution, enabling the reproduction of realistic, intricate sonic details. By using an electron beam (EB) deposition process to precisely coat the nanoscale diaphragm surface with aluminum circuitry, the design achieves precise vibration control and optimized segmentation, resulting in clearer layering and stable frequency response.
[Where Warmth Meets Precision] Experience vocals that evoke warmth and tranquility, bass that combines depth with power, and delicate, crystal-clear highs. With an expanded soundstage and dynamics and layering capabilities vastly superior to the previous model, the Apollo PRO offers an exceptional listening experience.

■ Lightweight ear cup structure featuring Zebrawood housings and a newly designed chamber.
・ The housings are crafted from Zebrawood—utilizing SENDY's signature wood-processing expertise—to ensure excellent durability and acoustic properties. A newly designed, compact chamber achieves a sophisticated ear cup structure while reducing overall weight. The mesh pattern features an ultra-thin, lightweight "Sunburst" metal mesh that combines a sunray-inspired aesthetic with excellent acoustic transparency. Dual 3.5mm connectors are used to ensure a secure and robust connection. ■ Optimized Fit for Comfortable Long-Term Monitoring
・The Apollo PRO utilizes aircraft-grade aluminum components that achieve a balance of light weight, high strength, and flexibility. Comfort is further prioritized through the use of a premium lambskin headband and breathable, skin-friendly velvet ear pads. With its exceptional sound response and lightweight, comfortable fit, the Apollo PRO is optimized for the extended monitoring sessions required by creators.

■ Premium 4-Core Cable Featuring Dual-Shielding and Triple-Composite Materials
・The Apollo PRO comes with a roughly 1.8m, 4-core cable featuring a dual-shielded design and a triple-composite conductor structure utilizing enameled gold-plated copper, silver-plated copper, and Furukawa Electric OFC (Oxygen-Free Copper). This triple-composite structure enhances resolution and delivers a rich, stable reproduction of acoustic details. The cable's inner layer employs a graphene-reinforced PVC structure that serves as both an insulator and an electromagnetic shield, while the outer layer combines copper braided mesh, silver-plated copper braided mesh, and a durable PVC jacket. This dual-shielding design significantly boosts tensile strength and durability while enabling extremely low-loss signal transmission. It is equipped with a 4.4mm balanced plug and includes a 4.4mm-to-3.5mm short adapter cable, a 3.5mm-to-6.35mm adapter plug, a linen accessory pouch, and a sturdy leather carrying case.

■ Traditional Handcrafted Woodworking and Design Identity
・SENDY AUDIO is committed to traditional, handcrafted production methods using wood. Significant time and manual effort are invested throughout the production process to select high-quality, natural solid wood materials. The process involves repeated stages of wood selection, cutting, CNC carving, polishing, painting, and air-drying. Consequently, the wood grain and texture of each pair of headphones are unique. Due to complex processes, manufacturing difficulties, long production times, and the scarcity of materials, we are limited to small-batch production; however, we remain dedicated to crafting each unit with the utmost care.
