Youtube Video Summary
Sennheiser’s IE900 delivers a sub-bass–focused tuning with tight control and real tactility, but its trademark upper-mid recession (≈2–5 kHz) keeps vocals and instruments a step back. A pronounced 9–10 kHz lift adds sparkle and air; depending on tolerance, that energy can read either engaging or a touch sharp/sibilant. Technical chops are strong for a single DD—resolution and microdetail are genuinely competitive.
The sticking point is tonal balance and value. While the IE900 is refined and punchy, that blunted midrange character contrasts with its bright treble, creating a love-it-or-leave-it “blue cheese” appeal. Against peers—and especially Sennheiser’s own IE600, which fixes the mids while preserving similar resolution—the IE900’s $1,300 price starts to look tough.
In short: choose the IE900 for its clean sub-bass slam, crisp transients, and airy top if that treble profile hits the spot. If the priority is natural mids and better value without giving up much technical ability, the IE600 feels like the smarter pick—and the real redemption of Sennheiser’s IEM line.
