MOONDROP Old Fashioned 40mm On-Ear Headphones

Classic Retro Design • Open-Back Sound • Modular & Audiophile-Tuned

Step into a golden era of personal audio with the MOONDROP Old Fashioned 40mm On-Ear Headphones—a perfect fusion of nostalgic design and modern acoustic engineering. Inspired by classic open-back on-ear headphones from the cassette era, the Old Fashioned revives timeless aesthetics while delivering a clean, natural, and fatigue-free listening experience tuned to Moondrop’s acclaimed DF-HRTF frequency curve.

At its core lies a 40mm large dynamic driver, meticulously engineered with optimized diaphragm damping and resonance control. This results in punchy bass, rich midrange vocals, and a smooth treble that remains comfortable even during extended listening sessions. The open-back architecture enhances soundstage and airiness, making music feel more spacious and lifelike.

Designed for both comfort and customization, the Old Fashioned features an ergonomic telescopic headband, multi-axis swivel hinges, and a fully modular detachable design. Both the ear cups and headband can be detached, allowing users to experiment with alternate wearing styles such as ear hooks or neckbands. The 0.78mm 2-pin interchangeable cable system ensures long-term durability and easy upgrades.

Whether you’re a retro audio enthusiast or a modern audiophile seeking character-rich sound, the MOONDROP Old Fashioned delivers a beautifully balanced listening experience wrapped in timeless style.
