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

Yes, it's expensive for a single DD imaging and separation is top tier with very good layering - frankly, I haven't heard many sets near this price that have done the same. There is a bit of subbass roll off but midbass hits hard. It's on the brighter side but never becomes shouty or sibilant. Timbre is good with vocals a bit forward in the mix. Tuning nozzles are a gimmick - they all sound the same. A better Kato in every way. I had a lot of trouble with fit on with this set - did not have the same problem with Hana 2021. Previously Owned

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

Japanese flavor of tuning (mid-bass and upper-mid focus) finally done justice. Strong technical chops and slightly forward.

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.

Smooth, detailed, and vocal-centric sound. Cohesive, vocal-focused tuning with dynamic bass, smooth extended treble, and excellent detail. Could use more sub-bass.

Just buy Fission. A cleaner/less warm LM, smoother EA1000 (fermats a little more resolving), very balanced, clean, and neutral sound. Very tough competition.
