Extremely versatile, they guarantee high-fidelity listening from both stereo systems and high-resolution mobile devices.\u003cbr\u003eThe SENNHEISER HD660S were developed from the previous HD 650 model: the transducers are hand-selected and assembled to ensure the same sound quality in both earcups (with a tolerance of approximately 1 dB). They ensure maximum fidelity in the reproduction of the highest notes, clear and well-balanced bass, excellent response in the mid-frequencies, and extremely natural highs. With an impedance of 150 ohms, the SENNHEISER HD660S can be used with high-resolution mobile players or connected to HiFi stereo systems. They express their full power when connected to amplifiers with balanced outputs, such as Sennheiser's HDV 820 or other digital players. They are equipped with OFC copper cables with both 6.35 mm jacks and 4.4 mm Pentaconn connectors, as well as 6.35 mm and 3.5 mm adapters.\u003c\/p\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\n\u003cli\u003eTransducer principle: Dynamic, open\u003c\/li\u003e\n\n\u003cli\u003eFrequency response: 9-41,500 Hz\u003c\/li\u003e\n\n\u003cli\u003eTotal harmonic distortion: \u0026lt; 0.04% (1 kHz, 100 dB)\u003c\/li\u003e\n\n\u003cli\u003eSound pressure level: 104 dB\u003c\/li\u003e\n\n\u003cli\u003eContact pressure: 6.0 N ± 1 N\u003c\/li\u003e\n\n\u003cli\u003eImpedance: 150 Ohm\u003c\/li\u003e\n\n\u003cli\u003eAudio connectors: 6.3 mm gold-plated stereo jack, unbalanced 3-pin 4.4 mm, balanced, 5-pin, 6.35 mm to 3.5 mm adapter\u003c\/li\u003e\n\n\u003cli\u003eConnecting cable: 3 m\u003c\/li\u003e\n\n\u003cli\u003eWeight (without cable): 260 g\u003c\/li\u003e\n\n\n\u003c\/ul\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":53994079486285,"sku":"HD660S","price":499.0,"currency_code":"EUR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0972\/0643\/6173\/files\/129386-large_default.jpg?v=1779950700","url":"https:\/\/musicdelivery.net\/en\/products\/sennheiser-hd660s-cuffia-dinamica-aperta","provider":"Music Delivery","version":"1.0","type":"link"}
