Same as Delci, graph and sounds the same, but cheaper with extra tuning filter Jays Audio Youtube Channel

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

Reviewer Score
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 .
