Sendy Audio Launches Apollo PRO: Lightweight Planar Magnetic Headphones

Sendy Audio has officially announced the launch of the Apollo PRO, a premium open-back planar magnetic headphone. Combining advanced nano-diaphragm technology with refined craftsmanship and a lightweight design, this new model is aimed at providing superior comfort during extended listening sessions. Available from June 2, 2026, the Apollo PRO is offered globally at a price of £449 / $449 / €499.

Nano-Diaphragm Technology for Detailed Sound Reproduction

At the heart of the Apollo PRO’s acoustic performance is a custom 78mm planar magnetic driver.

• Nano-Scale Diaphragm: The composite diaphragm structure measures less than 800 nanometres in thickness and is designed to enhance response speed, clarity, and overall resolution.
• Exclusive EB Deposition Technology: Sendy Audio utilizes “Electron Beam Evaporation Deposition” (EB) technology to precisely coat aluminium circuitry directly onto the diaphragm surface.
• Precision Vibration Control: This atomic-level coating process provides improved vibration control and optimized segmentation, contributing to clearer layering and a more stable frequency response.

Optimized Ergonomics for Long Listening Sessions

Weighing just 354g, the Apollo PRO is engineered to deliver the scale and openness of planar magnetic technology in a lighter, more comfortable design.

• Aesthetic and Durable Construction: The design features refined zebrawood earcups paired with a distinctive sunburst-pattern metal mesh, blending acoustic performance with a contemporary aesthetic.
• Premium Comfort Materials: Breathable velvet ear pads and a premium lamb leather headband are incorporated to reduce heat build-up and minimize listening fatigue during extended use.
• Adaptable Design: Precision CNC-machined aviation-grade aluminium components are paired with a flexible adjustment system, allowing the headband and earcups to adapt naturally for a more secure and comfortable fit.

Premium Connectivity and Technical Specifications

The included detachable cable is a complex hybrid constructed from Furukawa OFC, silver-plated copper, and enamelled gold-plated copper, designed for stable, interference-free signal transmission.

• Advanced Shielding: The cable features a graphene-reinforced PVC structure that serves as both insulation and electromagnetic interference (EMI) shielding, enhancing durability and signal integrity.
• Versatile Integration: The Apollo PRO includes a 4.4mm balanced cable alongside 3.5mm and 6.35mm adaptors, ensuring easy integration with a wide variety of portable and desktop setups.
