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

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. Jays Audio Youtube Channel
Sounds good, and fun.. Jaytiss Youtube Channel
Close ringer for the Harman IEM target with great bass and slightly harsh upper-mids and lower-treble. Precogvision Youtube Channel
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).
