A balanced 4.4mm connector opens a pathway to a newer generation of balanced output devices (headphone amplifiers, digital audio players, etc.) that embrace this compact plug’s superior stability over time. An optional XLR-4 balanced cable is available, providing yet another popular connection to a wide range of audio components. Each cable is 9.8ft \/ 3m long to accommodate unencumbered listening from devices anywhere on your shelves, in your studio, or on your desktop.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch2\u003e\n\u003cbutton class=\"collapse-btn show-less\" title=\"Show less\"\u003e\u003c\/button\u003eSpecifications\u003c\/h2\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"section-wrapper specifications-section\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"specifications-content-wrap open-table\"\u003e\n\u003cdiv class=\"table-wrapper\"\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eFrequency response (speaker)\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e6 Hz - 48,000 Hz\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eSound pressure level (SPL)\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e103 dB (1 V)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eImpedance\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e300 Ω\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eTotal harmonic distortion (THD)\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e\u0026lt; 0.02% (1 kHz, 100 dB)\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eCable length\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e3 m\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eadapter\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003eXLR-4, balanced, 4-pin Stereo jack plug: 1\/4\\ (6.35 mm), unbalanced, 3-pin 4.4 mm, balanced, 5-pin\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eTransducer principle (headphones)\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003edynamic, closed\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eWeight\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e360 g\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eEar coupling\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003ecircumaural\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eMagnetic field\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e10.5 mT\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"table-row\"\u003e\n\u003cdiv class=\"label\"\u003eArticle number (SKU)\u003c\/div\u003e\n\u003cdiv class=\"description\"\u003e507435\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"btn-wrap\"\u003e\u003cbr\u003e\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003csection class=\"product-info-section section-wrapper\"\u003e\n\u003cdiv class=\"container\"\u003e\n\u003cdiv class=\"product-info-row\"\u003e\n\u003cdiv class=\"product-info-col\"\u003e\n\u003cdiv class=\"product-info-inner\"\u003e\n\u003cdiv\u003e\n\u003ch3\u003eWhat's included\u003c\/h3\u003e\n\u003cdiv class=\"product-info-list\"\u003e\n\u003cul\u003e\n\u003cli\u003eHeadphones HD 820 (closed, dynamic headphones)\u003c\/li\u003e\n\u003cli\u003econnection cable: ¼” (6.35 mm) stereo jack plug (connected ex works), unbalanced\u003c\/li\u003e\n\u003cli\u003e4.4 mm stereo jack plug, balanced\u003c\/li\u003e\n\u003cli\u003einstruction manual\u003c\/li\u003e\n\u003cli\u003estorage box\u003c\/li\u003e\n\u003cli\u003emicrofiber cloth\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":41973777563709,"sku":"SEN-HD820","price":35750.0,"currency_code":"ZAR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2266\/2727\/files\/product_detail_x2_desktop_Sennheiser_HD_820_Headset_01_3691f2dd-0373-4d7a-8bf9-11d0b2e7e1e1.jpg?v=1776437064","url":"https:\/\/www.stationvibration.co.za\/products\/sennheiser-hd820","provider":"Station Vibration","version":"1.0","type":"link"}
