A New World of Sound Details

Even if you know your favorite songs by heart, the HD 505 reveals details you may have never noticed before: the soft thud of a piano key returning, the hum of a tube amp, the saxophonist’s inhale, or a buried synth line. This is what people often call “high-resolution” or “analytical” sound — as opposed to lesser audio tuned only for booming bass and extreme treble.

High-End Components and Tuned Acoustics

The optimized 120-ohm transducer from Ireland delivers clear mids and extended treble. Positioned forward inside the open-back cups, it helps create a spacious soundstage, giving the illusion of sound coming from precise locations in front of or behind you.

The HD 505’s wide frequency range captures sub-20 Hz vibrations you feel more than hear and extends beyond 20 kHz into ultra-high frequencies. Carefully tuned acoustics and damping ensure smooth, detailed treble that’s never harsh.

Comfort Meets Style

The HD 505 offers refined accents and premium comfort. Based on the lightweight HD 500 chassis, these headphones weigh only 237 g and feature a low clamping force for long listening sessions. A soft synthetic leather headband and velour ear cushions provide a luxurious feel.

Built for Long-Term Use

Designed with durability in mind, the HD 505 uses robust materials and high-grade metal mesh ear cups. Accessories and cables from the HD 500 series remain compatible, and replacement parts such as ear cushions will be available for years to come — ensuring long-lasting value.
