The frequency response is full, extending from 6Hz to 44kHz. THD is less than 0.2% at 100dB and the driver pairs are matched to within 0.05dB to maintain a sharp and accurate stereo image. They have a relatively easy to drive 38ohm nominal impedance and 112dB sensitivity so are equally at home with a dedicated desk amp as they are in a typical listening setup.\u003c\/p\u003e\n\u003cp\u003eA detachable Signature Silver cable connects to each earcup via secure 4 pin mini XLR jacks. The source end has a standard 3.5mm plug and includes a screw on 6.3mm adapter for use with home stereo. The cable has a soft flexible jacket which prevents the line from kinking and thus protects the internal conductors over time. Swapping cables or adjusting length is very easy in any system setup.\u003c\/p\u003e\n\u003cp\u003e335g adjustable metal headband to spread the clamping force evenly and avoid any hot spots on the head during long listening sessions. The stock B ear cushions are pre fitted to give a neutral acoustic response, the earcups are also capable of taking the optional S, F, L or G earcups should you wish to have a different feel or a wider soundstage.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Grado","offers":[{"title":"6 Foot \/ 3.5mm mini w\/ 6.3mm adapter","offer_id":47852611141716,"sku":"GR:SIGS550-6FT-MINI","price":995.0,"currency_code":"USD","in_stock":true},{"title":"6 Foot \/ 4.4mm balanced","offer_id":47852611174484,"sku":"GR:SIGS550-6FT-BAL","price":995.0,"currency_code":"USD","in_stock":true},{"title":"6 Foot \/ 4 pin balanced XLR w\/ 6.3mm adapter","offer_id":47852611207252,"sku":"GR:SIGS550-6FT-XLR","price":995.0,"currency_code":"USD","in_stock":true},{"title":"12 Foot \/ 3.5mm mini w\/ 6.3mm adapter","offer_id":47852611240020,"sku":"GR:SIGS550-12FT-MINI","price":995.0,"currency_code":"USD","in_stock":true},{"title":"12 Foot \/ 4.4mm balanced","offer_id":47852611272788,"sku":"GR:SIGS550-12FT-BAL","price":995.0,"currency_code":"USD","in_stock":true},{"title":"12 Foot \/ 4 pin balanced XLR w\/ 6.3mm adapter","offer_id":47852611305556,"sku":"GR:SIGS550-12FT-XLR","price":995.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0572\/3281\/8260\/files\/GradoSignatureS550Over-EarHeadphones_7.png?v=1792076620","url":"https:\/\/www.audioadvice.com\/products\/grado-signature-s550-over-ear-headphones","provider":"Audio Advice","version":"1.0","type":"link"}
