Was that sound from the room or the recording? Beyond a certain level of fidelity, it can be hard to tell. The HD505 might surprise you, especially if you’re new to high-end sound. Everything feels more real, you’re right in the middle of the action — without investing in big, expensive gear.

The HD 505 reveals a whole new world of small details. And it works for everything: music, movies, and gaming, too! People sometimes call it “high resolution” or “analytical” sound. (Contrast this with lesser audio products tuned for big, sloppy bass and lots of treble — but weak in the middle.)

Based on the HD 500 chassis, these headphones come at 237 g. They’re so light and comfy you’ll barely notice the cushy headband resting on your head. Less weight means lower clamping force, making them cranium-friendly. The synthetic leather headband and velour ear cushions give a lush vibe.

The transducer is the core of the HD 505 headphones, angled forward in open-back cups to create a realistic “soundstage.” With an expansive frequency range, it covers sub-bass you feel and high notes beyond human hearing. Fine-tuned damping ensures smooth treble—always brilliant, never harsh.

Sound that has nothing to hide.
