Sendy Audio Apollo Pro

The Sendy Audio Apollo PRO is an open-back, over-ear planar magnetic headphone designed for detailed and natural sound reproduction. Its premium construction combines zebrawood earcups, CNC-machined aluminum parts, and a refined open grille design.

At the core of the Apollo PRO is a 78 mm planar magnetic driver with a nano-scale composite diaphragm. This design supports fast transient response, controlled bass, and a wide frequency range for accurate listening.

The detachable tri-composite cable uses Furukawa OFC, silver-plated copper, and enamelled gold-plated copper conductors, and terminates in a 4.4 mm balanced connector. Included adapters expand compatibility with more traditional headphone outputs.

For comfort during longer sessions, the Apollo PRO uses a soft lambskin headband and breathable velvet ear pads. Its lightweight construction and premium materials make it suitable for serious listening with a stable and comfortable fit.
