Drew / Audionotions 4.5 Reviewer Score
Decent tuning that is perhaps slightly thin leaning. Average details but decent imaging. Bass has some punch but upper mids are a bit much and it can be a bit too bright. Interchangeable nozzles that work - the stock silver ones are better - the black ones are even more bright. Previously Owned

B+ Tuning
B- Tech

The Kefine Klean offers a versatile listening experience through its interchangeable nozzle system, with the silver filter providing a warmer, smoother profile while the black filter delivers enhanced treble clarity and presence . Its 10mm DLC diaphragm dynamic driver produces a balanced sound with natural mids and well-textured bass that avoids excessive boominess, though mid-bass can occasionally lack definition .

Comfort is a highlight, with the CNC-machined metal shells sitting ergonomically in most ears for extended sessions, though nozzle edges may cause minor irritation for some . Technical performance includes a moderately wide soundstage and competent imaging, though complex tracks can reveal limitations in separation and transient speed compared to higher-tier models .

Variations-ish tuning with sub-bass focused. Low-end is rumbly but lacks mid-bass impact/warmness in general. Fatiguing above mid-volume. Can sound light and thin. Mid-bass tuck affects libraries.

Spot on harman. Good bass impact for the bracket but the mid-bass is a bit scooped for my library. Treble needs some refinement but still a solid rec for the price bracket. Cheapest way to try this type of tuning (Variations etc).
