It is made for listeners who want their earphones to do far more than just sound clean and detailed, bringing the kind of balance, scale and refinement that makes serious listening possible almost anywhere.\u003c\/p\u003e\n\n\u003cp\u003eWhat makes the IE 900 especially impressive is the way it achieves such a revealing sound from a single dynamic driver design. Sennheiser’s 7 mm TrueResponse transducer is paired with the company’s X3R triple-resonator chamber system, which is designed to reduce unwanted resonances and uncover more low-level detail without making the sound harsh or fatiguing. The result is a presentation that feels fast, open and highly resolved, but still natural and musically engaging.\u003c\/p\u003e\n\n\u003cp\u003eIt is also built to feel every bit as special as it sounds. The precision-milled aluminium housings, premium detachable cables and generous accessory pack all give it the feel of a genuinely serious long-term purchase rather than just another portable earphone. For customers wanting a reference-grade in-ear headphone with outstanding clarity, control and high-end build quality, the Sennheiser IE 900 is an excellent choice.\u003c\/p\u003e\n\n\u003ch3\u003eKey Benefits\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eFlagship in-ear design delivers a truly serious audiophile listening experience in a compact format\u003c\/li\u003e\n\u003cli\u003e7 mm TrueResponse transducer is designed for fast, accurate and highly detailed sound\u003c\/li\u003e\n\u003cli\u003eX3R triple-resonator chamber technology helps reduce masking effects and reveal more low-level detail\u003c\/li\u003e\n\u003cli\u003eSingle dynamic driver design helps preserve coherence and tonal consistency across the frequency range\u003c\/li\u003e\n\u003cli\u003ePrecision-milled aluminium housings give the earphones a highly durable and premium feel\u003c\/li\u003e\n\u003cli\u003eGold-plated MMCX connectors add useful flexibility for cable changes and long-term ownership\u003c\/li\u003e\n\u003cli\u003eSupplied with 3.5 mm, 2.5 mm balanced and 4.4 mm balanced cables for wide source compatibility\u003c\/li\u003e\n\u003cli\u003e2 years manufacturers warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\n\u003cdiv id=\"hb-ie900-panel-2\" class=\"hb-panel\"\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eEarphone Details\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eProduct Type: Wired in-ear headphones\u003c\/li\u003e\n\u003cli\u003eDriver: 7 mm TrueResponse transducer\u003c\/li\u003e\n\u003cli\u003eAcoustic Design: In-ear with X3R triple-resonator chamber technology\u003c\/li\u003e\n\u003cli\u003eFrequency Response: 5 Hz - 48,000 Hz\u003c\/li\u003e\n\u003cli\u003eImpedance: 18 ohms\u003c\/li\u003e\n\u003cli\u003eHousing Material: Precision-milled aluminium\u003c\/li\u003e\n\u003cli\u003eConnector Type: Gold-plated MMCX\u003c\/li\u003e\n\u003cli\u003eCable 1: Para-aramid reinforced 3.5 mm cable\u003c\/li\u003e\n\u003cli\u003eCable 2: Para-aramid reinforced 2.5 mm balanced cable\u003c\/li\u003e\n\u003cli\u003eCable 3: Para-aramid reinforced 4.4 mm balanced cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat’s in the Box\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSennheiser IE 900 earphones\u003c\/li\u003e\n\u003cli\u003e3.5 mm cable\u003c\/li\u003e\n\u003cli\u003e2.5 mm balanced cable\u003c\/li\u003e\n\u003cli\u003e4.4 mm balanced cable\u003c\/li\u003e\n\u003cli\u003ePremium carry case\u003c\/li\u003e\n\u003cli\u003e3 pairs of silicone ear adapters (S, M, L)\u003c\/li\u003e\n\u003cli\u003e3 pairs of foam ear adapters (S, M, L)\u003c\/li\u003e\n\u003cli\u003eCable clip\u003c\/li\u003e\n\u003cli\u003eCleaning tool\u003c\/li\u003e\n\u003cli\u003ePresentation box with signed customer certificate\u003c\/li\u003e\n\u003cli\u003eProduct documentation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"Sennheiser","offers":[{"title":"Default Title","offer_id":57986987131267,"sku":null,"price":1299.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0160\/4606\/3670\/files\/Untitled_3500_x_3500_px_-_2026-05-06T114649.074.png?v=1778064614","url":"https:\/\/www.holburnonline.co.uk\/products\/sennheiser-ie-900-premium-in-ear-headphones","provider":"Holburn Online","version":"1.0","type":"link"}
