Acoustic silk is used to provide uniform attenuation across the ear cups, supporting consistent sound output. Lightweight aluminum voice coils improve transient response, while full-range drivers deliver a frequency response of 10 Hz to 39.5 kHz. The elliptical ear cup design follows the natural shape of the ears for extended wear comfort. A detachable 9.8 ft cable made from highly conductive OFC copper helps reduce handling noise and signal loss. The headphones work with portable audio devices and are designed for use with stationary hi-fi components, including SACD, DVD-A, and CD players. A 1\/4 inch to 3.5 mm adapter is included for connection flexibility.\u003c\/p\u003e\u003ch3\u003eOpen, Dynamic, Circumaural Design\u003c\/h3\u003e\u003cp\u003eDelivers a spacious, natural soundstage with accurate stereo imaging for critical listening and audiophile use.\u003c\/p\u003e\u003ch3\u003eAudiophile Sound Reproduction\u003c\/h3\u003e\u003cp\u003eEngineered for reference-class performance, producing detailed, transparent sound with exceptional balance and clarity.\u003c\/p\u003e\u003ch3\u003eExtended Frequency Response (10 Hz – 39.5 kHz)\u003c\/h3\u003e\u003cp\u003eFull-range drivers reproduce deep bass, natural mids, and refined highs with precision across the entire spectrum.\u003c\/p\u003e\u003ch3\u003eAcoustic Silk Attenuation\u003c\/h3\u003e\u003cp\u003eSpecially developed acoustic silk provides uniform attenuation across the ear cups for consistent tonal accuracy.\u003c\/p\u003e\u003ch3\u003eLightweight Aluminum Voice Coils\u003c\/h3\u003e\u003cp\u003eExtremely lightweight construction ensures fast transient response and improved dynamic performance.\u003c\/p\u003e\u003ch3\u003eElliptical Ear Cup Design\u003c\/h3\u003e\u003cp\u003eErgonomically shaped ear cups naturally adapt to the ears, offering superior comfort during extended listening sessions.\u003c\/p\u003e\u003ch3\u003eHighly Conductive OFC Copper Cable\u003c\/h3\u003e\u003cp\u003eDetachable 9.8 ft cable minimizes signal loss, handling noise, and structure-borne sound interference.\u003c\/p\u003e\u003ch3\u003eWide Device Compatibility\u003c\/h3\u003e\u003cp\u003eWorks with portable audio devices and excels when paired with high-quality stationary hi-fi components.\u003c\/p\u003e\u003ch3\u003eHigh-Resolution Audio Support\u003c\/h3\u003e\u003cp\u003eCompatible with SACD, DVD-A, and CD players for premium playback quality.\u003c\/p\u003e\u003ch3\u003eIncluded Adapter\u003c\/h3\u003e\u003cp\u003eShips with a 1\/4 inch to 3.5 mm adapter for flexible connectivity across professional and consumer audio equipment.\u003c\/p\u003e","brand":"Used Department","offers":[{"title":"Default Title","offer_id":43057356865584,"sku":"508825_FCLN-FC","price":379.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/3219\/9216\/files\/3620547.jpg?v=1779396813","url":"https:\/\/focuscamera.com\/products\/sennheiser-508825-fcln-fc-audio-electronics-headphones-earbuds","provider":"Focus Camera","version":"1.0","type":"link"}
