Sennheiser IE600 Reviews
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. Crin Youtube Channel
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. Jays Audio Youtube Channel
Very well rouned fun subbass focus sound Treble might be too much Tim Tuned Youtube Channel
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.Gizaudio Axel original ranking

Comment: Stock eartips are a disgrace. Superb clarity with good tuning and bass response Treble is on the energetic side
Lots of upper trebble. Jaytiss Youtube Channel
Well-extended on both ends of the spectrum and adds back in the upper-midrange the IE900 lacked. Precogvision Youtube Channel
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.

It's a step down from U12T in techs, yes, but it's still competitive in the price range. In exchange, tonality and timbre are much improved, which, IMO, is much more important. Imaging, separation, resolution, stage, and dynamics are excellent. Bass is deep and very well textured. Mids have great body. Treble is detailed and extended with great air while never being sibilant or harsh. Really easy to pop on and get lost in the music with. Warm and gooey in the best way possible. Lush, rich, soulful. Previously Owned
Warm, thick, and with excellent dynamics. U12t's tubby younger brother that could use more resolution. Precogvision Youtube Channel
Nice graph, but images weird for an iem of this cost. Jaytiss Youtube Channel
