Comment: Treble tuning is one of the best up to $200 range. Neutral bright decently tuned, decent soundstage, surprising treble tuning Limp bass with zero texture, might be too bright for some

Sounds like vocalists are asphyxiating. Very thin note-weight. Precogvision Youtube Channel

Budget tech king due to neutral bright tuning. Needs and loves power. My favourite sub-50 set so far. Might come out as shouty/hot. Responds well to EQ and Moding. Beaten by CRA(bassy) and Titan S for my library.

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 .
