Kefine Quatio Review - Flexible Refinement and Musical

Описание: There are occasions were reviewing an iem is a very involved task. With some of the best I have heard this often was the case. Excellence isn’t often immediately apparent, in particular when having the opportunity to listen to so many earphones. Weather it’s a matter of being jaded or due that infamously fickle audio memory this has been my experience.
Then there are those rare occasions where an iem’s sound is unpretentious and even at first listening makes clear what it is capable of. The Kefine Quatio is one of those earphones that from opening the box and putting them in my ears laid bare it’s refined musical character.
Kefine was founded only in 2022 and released their fist product, a Planar based iem in 2023. The driving force behind the company is to produce products where high quality does not mean high prices. According to their webpage they do this by keeping non-sound related things like simple packaging and omitting unnecessary accessories to a minimum while spending that development budget on the actual iem.
The Quatio is their latest and most ambitious release retailing at $130USD. Driver compliment includes dual dynamic drivers, a 10mm and an 8mm, paired with two balanced armatures. A three-way hybrid crossover, electric and acoustic, keeps everything in check. The Quatio also ships with three sets of tuning nozzles which Kefine describes as Silver (Balanced), Gold (Transparent) and Black (Warm). All sound good by the way. From the company graphs the nozzles have negligible effects on the bass but do influence the midrange on up with each affecting the energy from the mids into the treble, nut not in an aggressive way.
Tuning wise we have a balanced tuning with added bass presence. Overall, it is a safer type of approach with respect to the midrange and treble but done in a pleasing way and not boring by any measure. The added bass lift does not make the Quatio a Basshead iem, but it is clearly present.
The Quatio likes power and can be a reasonably resolving set. It is recommended to pair it with a source that has decent power output and a clean balanced sound. Tip selection is also crucial here as I did find the Quatio is tip sensitive and did my usual tip-rolling to find that perfect synergy. Trust me when I say it is well worth the effort.
**The balanced nozzles were used for the majority of listening impressions unless otherwise indicated.
