About the Sennheiser IE 900

Top-flight IEMs from the headphone specialists

Few phrases capture the attention and imagination of the high-end headphone community like: "new flagship from Sennheiser." The IE 900 wired headphones are the company's top-of-the-line earbuds, and they promise a spacious, vividly detailed sound. I just received a sample, so I'll have listening impressions soon. I can report that the ergonomic design closely resembles one of my favorite in-ears, the Sennheiser IE 300 — but these premium earbuds feature upgraded drivers, striking milled aluminum housings, and a more sophisticated airflow control system.

Each Sennheiser IE 900 earbud features a single 7mm premium driver and an intricately designed series of filters and air chambers.

Ever-mindful of high-end harshness, Sennheiser has developed a "triple-chamber absorber" system that combats distortion in the treble. It even tames those gnarly resonances from super-high frequencies that can sometimes creep into the range of human hearing. That ensures that we hear refined, yet articulate highs to complement the well-pronounced mids and deep, clean bass.
