The HD 505 reveals a whole new world of small details like these. 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 crazy amounts of treble - but weak or mushy in the middle.)\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e\u003cimg src=\"https:\/\/www.pbtech.co.nz\/fileslib\/_20250603092848_323.png\" style=\"max-width: 100%; height: auto; display: block; margin: 16px auto; border-radius: 6px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e \u003c\/p\u003e\n\u003ch3 style=\"font-size:18px;font-weight:600;color:#222;margin:20px 0 10px 0;\"\u003eHigh-end components and perfectly tuned acoustics\u003c\/h3\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003eAn optimized 120-ohm transducer from our own facility in Ireland delivers clear mids and extended treble.\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003eThe transducer is the heart of the headphone. It includes the magnet and diaphragm that vibrate to produce sound. We angled this one forward in the open-back cups to help create the \"soundstage\": that's when it feels like sound is coming from a specific spot in front of (or behind) you. Close your eyes, and you can imagine being on a stage: that saxophone player slightly left of center, the piano further off to the right, the guitar amp behind the sax…\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003eThe impressive frequency range of the HD 505 covers sounds you feel more than hear (below 20 Hz)as well as high frequences in dog-whistle territory (over 20 kHz). And, of course, we tweaked the acoustics to eliminate gaps and maximize detail. Fine-tuned damping behind the transducer, for example, ensures smooth lower treble response -always brilliant, never overdone (unlike Aunt Mary's meatloaf!).\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e\u003cimg src=\"https:\/\/www.pbtech.co.nz\/fileslib\/_20250603092836_932.png\" style=\"max-width: 100%; height: auto; display: block; margin: 16px auto; border-radius: 6px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e \u003c\/p\u003e\n\u003ch3 style=\"font-size:18px;font-weight:600;color:#222;margin:20px 0 10px 0;\"\u003eAppealing accents and serious comfort\u003c\/h3\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003eThe sophisticated color accents of the HD 505 make a great first impression.

Robust product design is a hallmark of German engineering, after all. The HD 505 is no different: you get less plastic, more lux. Those high-grade metal mesh ear cups really set the tone, for example. Accessories from our HD 500 series, including all cables, are compatible. And you'll have access to those items, as well as replacement parts like ear cushions, for many years to come.\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e\u003cimg src=\"https:\/\/www.pbtech.co.nz\/fileslib\/_20250603092811_597.png\" style=\"max-width: 100%; height: auto; display: block; margin: 16px auto; border-radius: 6px;\"\u003e\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e \u003c\/p\u003e\n\u003ch3 style=\"font-size:18px;font-weight:600;color:#222;margin:20px 0 10px 0;\"\u003eDescribing the HD 505 sound with a frequency response curve\u003c\/h3\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003eHeadphone frequency response graphs look very different from those for loudspeakers, which are ideally very flat. Here you can see a big rise on the right (treble) side and then it falls off a cliff. But this is in fact very close to what's considered ideal for headphones. It's called the Harman Curve. This industry benchmark is based on extensive psychoacoustic research into listener preferences.\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003eFor instance, it turns out that headphones negate the function of the outer ear, which otherwise amplifies sounds in the 3 kHz region. So the ideal response for headphones is much higher there. Resonances in the inner ear also make sounds between 7 and 10 kHz louder, which is why the graph dips abruptly around 8-9 kHz. We can see here that the HD 505 builds on the already excellent characteristics of the HD 599, extending even further into subbass territory while still offering strong, analytic mids and brilliant treble without sibilance or harshness.\u003c\/p\u003e\n\u003cp style=\"margin-bottom:16px;font-size:15px;line-height:1.6;color:#444;\"\u003e\u003cimg src=\"https:\/\/www.pbtech.co.nz\/fileslib\/_20250603092748_217.jpg\" style=\"max-width: 100%;
