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.

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
I don't get it, not even a little. Jaytiss Youtube Channel
Excelllent bass - simply excellent. Midrange could use some work, as could the generally average imaging chops. Precogvision Youtube Channel
Well-resolving DD IEM with excellent treble control, though with somewhat weak mid-high harmonics. Crin Youtube Channel
