Sennheiser IE 900 Earphones

Sennheiser IE 900 Earphones are high-end in-ear monitors engineered for natural, highly detailed sound in a compact wired design. Each earpiece uses a 7 mm TrueResponse dynamic driver inside a precision-milled aluminum housing, paired with Sennheiser’s X3R triple-resonator chamber technology to smooth resonance peaks and preserve clarity. The result is sparkling treble without harshness, tight bass without muddy mids, and strong separation for critical listening. Multiple cable terminations (2.5 mm, 3.5 mm, and 4.4 mm) and MMCX connectors support a wide range of sources. Silicone and foam tips plus adjustable ear hooks help create a secure, comfortable seal.
