{"product_id":"sennheiser-hd-400-pro-354820","title":"HD 400 Pro","description":"\u003ch3\u003eAn Heir to Sennheiser's Precision\u003c\/h3\u003ePart of the brand's line of reference open-back headphones, the HD 400 PRO emphasizes neutrality and clarity in the lower spectrum, two essential criteria for modern mixing work. Compared to previous generations, it features angled transducers and optimized tuning for an even more linear tonal balance, while maintaining the natural listening signature typical of Sennheiser open-back headphones.\u003cbr \/\u003e\u003ch3\u003eWho It's For and Intended Uses\u003c\/h3\u003eThe HD 400 PRO is aimed at sound engineers, producers, beatmakers, and content creators seeking a reliable monitoring headphone for both home and studio use. Its spacious soundstage facilitates fine editing, element placement in the panorama, and reverb control. Like all open-back headphones, it excels in mixing and mastering but is less suited for close-miking recording situations.\u003cbr \/\u003e\u003ch3\u003ePrecision, Comfort, and Reliability for Everyday Use\u003c\/h3\u003eIts acoustic tuning favors a linear response from 6 to 38,000 Hz, with extended and controlled bass to assess low-end balance without overload. The open architecture and angled transducers provide realistic spatialization that highlights the depth and width of your mixes while minimizing internal coloration.\u003cbr \/\u003eErgonomically, its 240 g weight, adjustable headband, and velvet ear pads ensure discreet wear during long sessions. The single-sided cable reduces clutter, while the choice between straight and coiled cables adapts to your desk or control room setups. With an impedance of 120 Ohms and total harmonic distortion below 0.05%, the HD 400 PRO combines dynamics, clarity, and low listening fatigue, perfectly compatible with most current audio interfaces.\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFormat\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003ecircumaural\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eDesign\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eopen\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003ctable style=\"flex:1 1 300px;width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eImpedance\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e120 Ω\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eColor\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003eBlack\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"display:flex;flex-wrap:wrap;gap:2rem\"\u003e\n\u003cdiv style=\"flex:1 1 300px\"\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eWeight without cable\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e240 g\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003cdiv style=\"flex:1 1 300px\"\u003e\n\u003ctable style=\"width:100%\"\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eSPL\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e110 dB (1 kHz \/ 1 V RMS)\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eFrequency response\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e6 - 38,000 Hz\u003c\/td\u003e\u003c\/tr\u003e\n  \u003ctr\u003e\u003ctd style=\"text-align:left\"\u003e\u003cstrong\u003eTHD\u003c\/strong\u003e\u003c\/td\u003e\u003ctd style=\"text-align:left\"\u003e\u0026lt; 0.05% at 1 kHz \/ 90 dB SPL\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/table\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":54361825542419,"sku":"354820","price":231.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0984\/0872\/6803\/files\/10281bde611377278bcafdcfcad3e2c3f3bb991e_SENNHEISER_HD400_PRO.jpg?v=1787434977","url":"https:\/\/woodbrass.shop\/products\/sennheiser-hd-400-pro-354820","provider":"Woodbrass.com","version":"1.0","type":"link"}
