Audionotions 8.5 Reviewer Score
I usually don't like things that aren't all rounders but this might be the exception. Bass is incredible - best in class - great texture, fantastic physicality. Treble response is great too - pretty resolving. There is a noticeable recession in the upper mids, giving these a fairly U/V shaped sound signature - violins, for example, lack a bit of brightness/bite that I would hope for. But unlike other V-shaped IEMs, the mids aren't offensive. Incredibly fun to listen to. Probably the best single DD available. EQ highly recommended. Previously Owned

Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops.

Well-resolving DD IEM with excellent treble control, though with somewhat weak mid-high harmonics.
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.
