KEFINE QUATIO REVIEW

>>I am brazilian and I speak portuguese, so forgive my english, I’ll use translation tools to help<<

INTRO:

After reviewing the excellent KEFINE KLEAN, I’ve made this IEMs my top recommendation for up to $50 USD. It was a pleasant surprise, I really liked them. Now, we have the opportunity to review the company’s new IEMs, the KEFINE QUATIO. The Quatio are very competitively priced for their price range, especially since — beyond to being a hybrid — they come with a kit with many accessories and the option to replace filters. So, even before we begin, we already have some very positive points for the consumer.

Price: $129,99 USD

UNBOXING:

PHYSICAL ASPECTS:

Construction:

• The shell is made entirely of aviation-grade aluminum.
• Removable nozzles. 3 pairs of filters: silver, black, and gold.
• Minimalist design: I like it, although it’s a bit too orthodox this time.
• Excellent build quality. Sturdy.
• Great unboxing experience.
• Product comes with several accessories (great for the consumer).
• Good carrying case. Semi-rigid. Lightweight. Compact.

Eartips:

• Great eartip kit. Good quantity (13 pairs).
• They are good quality eartips. The silicone is very soft.
• There are two types: those with a thicker tube and those with a thinner tube.
• The thinner tube is more comfortable (personal opinion).
• These are standard size eartips: if you wear a M, then you wear an M.
• The diameter is also standard: not too narrow or too wide.
• I don’t see the need to buy more eartips (subjective).
• There is a good quantity, but the variety is okay (it’s not a Titan S2).
• I made the review with the white ones (white tube & dome) [size M].

Cable:

• Modular cable with 2 detachable plugs.
• 3.5mm & 4.4mm Balanced plugs.
• Great system: easy to swap out and doesn’t increase the plug size.
• The cable is thicker than I’d like, but it’s still standard.
• Good malleability.
• Doesn’t get tangled.
• Doesn’t get “memory” (creases).
• No microphonics.
• The earhooks are wavy, but they weren’t bothersome.
• The Chin Slider is 100% effective. It works very well.
• 2-pin 0.78mm connectors.

Fit and comfort:

• Great fit – stable in the ears (subjective).
• Very comfortable. Excellent ergonomics.
• Good for medium to large ears.
• Medium insertion.
• Good/okay isolation.
• At 7.5g, it’s not the lightest, but it’s okay.
• Obviously, metal IEMs are a bit heavier.

Earphone kit (accessories):

• Quatio earphones
• 13 pairs eartips sizes S/M/L.
• Modular cable with 3.5mm & 4.4mm plugs.
• Semi-rigid case.
• 3 pairs of filters (detachable nozzles).
• Manual, guide, QC pass.

SOUND ASPECTS:

Sound:

• Mild V-shape with more emphasized bass.
• Stronger bass, balanced mids, and linear treble.
• All-rounder sound: good for many genres.
• Fast and clean sound.
• No “warming” effect due to the bass.
• Not “energetic,” although it’s fun.
• Great detail and technicality.
• IEMs for bassists and drummers listening to recordings.

Bass:

– Quantitative:

• Moderate to high.
• The boosted region in the IEM.
• I don’t consider it a basshead, but it will be very pleasing to those who like bass.
• Sub-bass and mid-bass are very present.
• I think there’s a balance between the two regions.
• I didn’t feel any overlap. Both regions stand out equally.

– Qualitative:

• While quantitatively isn’t a basshead, qualitatively it can be quite pleasing.
• The bass is fast, clean, controlled, well-defined, and with great extension.
• The bass has strength, weight, and impact.
• It has great physicality; you can hear the kick of the bass drum.
• The bass isn’t slow, thick, or overly textured; in other words, the presentation is “cleaner.”
• The bass resolution is excellent for the price range.
• It doesn’t invade the midrange.
• Great for all musical genres, especially the more “fun” ones.
• Very good for listening to bass guitar or drums with more emphasis.
• Lower notes of a piano you feel the weight and at the same time the definition of the sound.
• I understood that the Quatio’s bass doesn’t create “warmth” for the presentation.

Mids:

– Quantitative and qualitative:

• Well-balanced mids.
• Neither recessed nor forward.
• Well-placed pinna gain. Consistent.
• The upper-mids bring clarity at just the right point.
• I didn’t experience any hearing fatigue in this region.
• I have more sensitivity in this region and didn’t experience any fatigue.
• Excellent clarity, definition, and transparency.
• The snare drum has a lively and defined sound.
• I didn’t feel any aggression in any instrument.
• Not for those who enjoy very textured or warm mids.
• Best suited for those who enjoy more technical mids.

Voices:

• Excellent performance for both high and low voice types.
• Male/low voices have power.
• Female/high voices have clarity and good projection.
• The Quatio provide a good balance for both vocal types.
• Good for both, but not excellent for one specific type.

Treble:

– Quantitative:

• Moderate treble.
• Not for Trebleheads (those who seek more treble).
• Recommended for those who are sensitive to treble.
• Free from hearing fatigue.
• Everything I heard, nothing went overboard.

– Qualitative:

• Balanced, linear, controlled treble, good extension, and excellent definition.
• Natural sparkle. Consistent.
• Great detail and good airy.
• Not shrill, sharp, or harsh.
• I didn’t experience any sibilance, peaks, or coloration.
• Treble that are suitable for a wide variety of genres.
• I don’t consider it “energetic” because the treble are just right.
• A steel-string guitar sounds detailed and natural.

Filters (removable nozzles)

• The difference between the three is quite subtle.
• The gold filter was the one I used in the review.
• The gold one, for me, made the midrange more forward.
• I didn’t notice any significant differences between the black and silver.
• Honestly, differently shaped eartips can change the sound more.

Soundstage:

• Good soundstage.
• Very good width, and good/okay height and depth.
• It can easily display sounds from the front and rear.
• Because it’s not as deep, the sound tends to be less spatial.

Imaging:

• Excellent instrument separation. A very positive point.
• Great cutting of instrument placement.
• On drums, you can hear where the sound of each instrument part is coming from.
• Hybrid IEMs tend to have more imaging (personal opinion, not a rule).

Driver Flex Test:

• I didn’t experience any driver flex when inserting the IEMs into my ears.

Amplification:

• Easy to push.
• No need powerful amplifier.
• A simple dongle is enough.
• I used the Quatio with the FiiO KA11.
• It will play well directly from smartphones or iPads.
• Volume below 20 (of the 100 available on the W10).
