{"product_id":"sennheiserhd550","title":"Sennheiser HD 550 Open-Back Over-Ear Headphone","description":"\u003cp\u003eThe Sennheiser HD 550 is an open-back over-ear headphone that delivers detailed, neutral sound from 150-ohm drivers made in Ireland, for focused music enjoyment at home. It's the entry ticket into a sound world where you suddenly hear things in familiar recordings that had gotten lost before.\u003c\/p\u003e\n\u003ch2\u003eWhy the HD 550?\u003c\/h2\u003e\n\u003cp\u003eThe open-back design creates a wide, airy stage that closed-back headphones can barely achieve. At just 237 grams and with low clamping force, you simply forget you're wearing it after a while - ideal for long sessions. And because it's designed for a long life and repairable with original spare parts, you're not buying a disposable item.\u003c\/p\u003e\n\u003ch2\u003eWhat you hear\u003c\/h2\u003e\n\u003cp\u003eThe HD 550 builds on the well-regarded HD 599 but goes deeper into the sub-bass: solid, pleasantly powerful bass, balanced mids and precise, airy highs without harshness or sibilance. The result is a natural, honest sound that doesn't gloss over or exaggerate anything.\u003c\/p\u003e\n\u003ch3\u003eWho is the HD 550 for?\u003c\/h3\u003e\n\u003cp\u003eFor anyone who listens to music with focus at home, enjoys films, or wants to pinpoint every footstep while gaming - it's mic-compatible too. Straight talk: open means open. It lets the environment in and sound out, so it's not for the open-plan office or the train. At 150 ohms it plays off a phone, but it takes things up another notch with a good headphone amp.\u003c\/p\u003e\n\u003ch2\u003eOur verdict\u003c\/h2\u003e\n\u003cp\u003eA lot of audiophile sound per gram - light, comfortable, and surprisingly deep. If you're looking for an entry into open, detailed listening, the HD 550 is a hot candidate. We at HD Zürisee in Wädenswil are happy to show you what a suitable source or a headphone amp can add.\u003c\/p\u003e\n\u003ch2\u003eTechnical data\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eDesign: over-ear, open-back\u003c\/li\u003e\n\u003cli\u003eDriver principle: dynamic\u003c\/li\u003e\n\u003cli\u003eImpedance: 150 ohms\u003c\/li\u003e\n\u003cli\u003eFrequency response: 6 Hz - 39,500 Hz\u003c\/li\u003e\n\u003cli\u003eSound pressure level: 106.7 dB \/ 1 V RMS\u003c\/li\u003e\n\u003cli\u003eTotal harmonic distortion (THD): \u0026lt; 0.2 % (1 kHz \/ 90 dB SPL)\u003c\/li\u003e\n\u003cli\u003eEar pads: synthetic velour, replaceable\u003c\/li\u003e\n\u003cli\u003eConnector: detachable cable\u003c\/li\u003e\n\u003cli\u003eCable length: 1.8 m\u003c\/li\u003e\n\u003cli\u003eWeight: 237 g\u003c\/li\u003e\n\u003cli\u003eIncluded: HD 550, detachable 1.8 m cable, drawstring pouch\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eDoes the Sennheiser HD 550 need a headphone amp?\u003c\/h3\u003e\n\u003cp\u003eNot strictly, but it's worth it. At 150 ohms, the HD 550 already runs off a phone or laptop. With a headphone amp or DAC\/amp it audibly gains dynamics, control and deep bass - we're happy to advise you on what pays off for your setup.\u003c\/p\u003e\n\u003ch3\u003eOpen or closed-back - what does that mean in practice?\u003c\/h3\u003e\n\u003cp\u003eThe HD 550 is open-back. That gives a wide, natural soundstage, but it lets ambient noise in and sound out. Perfect for a quiet room at home, less suited to the office, the train or the library.\u003c\/p\u003e\n\u003ch3\u003eIs the HD 550 suitable for gaming?\u003c\/h3\u003e\n\u003cp\u003eYes, very much so. The wide stage helps you locate sounds, and the headphone is mic-compatible. For long sessions it scores with low weight and low clamping force, so nothing pinches even after hours.\u003c\/p\u003e\n\u003ch3\u003eWhy buy the Sennheiser HD 550 from HD Zürisee?\u003c\/h3\u003e\n\u003cp\u003eBecause an open-back, high-end headphone only really blossoms with the right source - and that's exactly where we come in.
