What sets the new Sennheiser in-ear headphones apart

The 7 mm TrueResponse transducers are the heartbeat of the Sennheiser IE series. In a discrete and small package, these dynamic drivers offer the coherent, artifact-free “Sennheiser Sound” already seen in our full-size headphones (which are up to 8 times larger). Every single transducer is produced to rigorous quality standards at our German headquarters.

What sets the new Sennheiser in-ear headphones apart

Extracting every audio detail in its purest form requires a specific approach—especially in the confines of the ear canal. Each Sennheiser audiophile IE earphone utilizes a frequency absorber system to pinpoint and remove the masking resonance peaks that would otherwise bury the very nuances you seek. Discover the IE 900 with its unique X3R technology containing three Helmholtz resonator chambers and an acoustic vortex.

»Our team of engineers sought to deliver the integrated, cohesive listening experience of a finely tuned loudspeaker or flagship headphone at a fraction of the usual size. The dynamic single transducer principle offers the opportunity to bring listeners the full-bodied sound of a complex multi-driver system without the phase complications or durability concerns. Across the range, you will experience brilliant transient retrieval, impressive dynamic range and effortless response throughout the functional range of human hearing.«
