Sendy Audio Apollo: Open-Back Planar Magnetic Headphones with Quad-Former Technology
Inspired by the acclaimed flagship Peacock, the Sendy Audio Apollo features Quad-Former technology—a proprietary planar magnetic driver design with four voice coils and dual magnets per driver, delivering ultra-efficient magnetic conversion for a sound that is precise, natural, and deeply musical.
Advanced Planar Magnetic Design
Each 68 mm planar driver uses dual coils on both sides of the diaphragm, enhancing dynamics while minimizing distortion. The ultra-thin 3-micron composite diaphragm—developed over two years—combines the rigidity needed to reach 40 kHz with the damping required for tight bass and warm, fluid mids.
Handcrafted Rosewood Construction
The ear cups are precision-machined from solid rosewood and hand-finished, offering not only a luxurious appearance but also improved resonance and openness. The frame and hardware are made from aerospace-grade CNC-machined aluminum, ensuring durability and light weight.
Comfort Meets Elegance
The round earpads are made from memory foam and soft leatherette, designed in a bowl-shaped profile for ergonomic fit. The suspension-style headband evenly distributes weight, making the Apollo ideal for long listening sessions without fatigue.
