Well-extended on both ends of the spectrum and adds back in the upper-midrange the IE900 lacked.

Interesting tuning that has some sense of special sauce but falls short in the execution.

Engaging sound signature with authoritative bass and very good treble. Mids are no slouch either. Can be spicy for some, but for what it's worth, I have no issues with the treble. Pretty impressive, not just for single DDs but for any driver config. Previously Owned

Well-tuned mids, powerful yet controlled sub-bass, with highly extended (and somewhat spicy) treble.

Tons of detail and amazing clarity. Stage is smaller than most IEMs at/below its price tag but very well defined details and imaging within that space. Bass is detailed, but amount is not as much as graph would suggest. Treble gets sharp and fatiguing at longer-listening/higher volumes. Stage can feel cramped.

Fun, V-shaped tuning. Fantastic bass (both quality and quantity), great V-shaped tuning, excellent detail, and precise imaging. Treble is too much, could use more vocal focus.

The most technical DD I've heard. Tuning is not perfect for my library - V-Shape. Get's a rec for those that really enjoy a well done V DD. Could use more stage size and bass impact. Fit is not the best, but good comfort for me.
