UNBOXING:

PHYSICAL ASPECTS:

Construction:

• Shell with aluminum parts and plastic parts.
• Beautiful aesthetic IEM (subjective).
• It has 1 vent by side.
• Good construction quality.
• Good accessory kit.
• Great case. Rigid, spacious, light, and elegant. Made of 3D printing.
• The only issue of the case is that it takes a long time to unscrew the lid.

Eartips:

• This part needs attention in the product.
• 2 Types of eartips: Normal and wide bore.
• I couldn’t get a good fit and isolation with the stock eartips.
• I changed the eartips and solved the problem.
• I think it’s necessary to purchase extra eartips for this IEM.
• I made the review with the Spinfit CP100 (size. M).

Cable:

• Great cable.
• Great quality cable, and beautiful too.
• Very light and thin.
• Good malleability.
• Doesn’t get tangled.
• It doesn’t take “memory” (creases).
• Earhooks are great (without wavys).
• Didn’t have microphony.
• The chin slider works 99% well.

Fit and comfort:

• I only got a proper fit after the change of the eartips.
• With the stock eartips, the IEM was coming out of my ears.
• Very comfortable, very light IEM.
• Good format for all types of ear.
• Good for long hours of use.
• Average insertion (depends on the eartip).
• Good/OK isolation (depends on the eartip).
• The nozzle could be thinner (subjective).

Earphone kit (accessories):

• D02 earphones.
• 3 pairs of “Normal” eartips, sizes S/M/L.
• 3 pairs of Wide Bore eartips, sizes S/M/L.
• 3.5mm cable.
• Plastic/rubber carrying case.
• Manual, warranty & QC card.

SOUND ASPECTS:

Sound:

• Mid-centric sonority, forward mids.
• Neutral tuning.
• Upper-mids with more prominent.
• Bass and treble are committed.
• Good clarity and transparency in the sound.
• Great for listening to vocals.
• It’s important to choose the right eartip to adjust the sound balance.
• I think it’s not an all-rounder IEM.
• It may lack the amount of bass for some genres (subjective).

Bass:

– Quantitative:

• Moderate tending to low.
• Isn’t for bassheads.
• Mid-bass and sub-bass in balance.
• I felt no difference between one region and another.
• Eartips can give or take more bass (you need to try).

– Qualitative:

• They are dry, lean, clean, controlled, with good definition, and good extension.
• More soft on impact, texture and physicality.
• They are bass that follow the recordings, don’t seek to be the star.
• Don’t invade the mids.
• They aren’t bloated, boomy, or muddy.
• Good for many genres, perhaps not so for EDM, POP, Hip-Hop (subjective).
• They are neutral bass, so they will go better with more “calm” songs.

Mids:

– Quantitative and qualitative:

• Forward mids.
• Pinna gain with good projection.
• Upper-mids are the soul of the IEM.
• The sound of the IEM is centered on this region.
• Great clarity and transparency.
• Great resolution and airy.
• It didn’t notice aggressiveness at any time.
• Suitable for those who enjoy prominence on vocals.
• If you are very sensitive to upper-mids, then it may not be indicated.
• I’m sensitive in this region and I didn’t feel uncomfortable (but not my favorite tuning).
• Wind instruments are highly prominent. Palpable.
• I really enjoyed listening to jazz/sax with this IEM.

Voices:

• Female/high voices were better performance.
• More air and energy for the most high voices.
• More vitality for mezzo-soprano and soprano voices.
• Male/low voices aren’t good. It lacks texture.
• This IEM brings the ability to shiver you with closer vocals.

Treble:

– Quantitative:

• Moderate treble.
• Isn’t for trebleheads.
• Well -implemented treble.
• I didn’t feel fatigue because of the treble.
• After the mids, I think it’s the second best region of the IEM.

– Qualitative:

• Linear, controlled, fast, good definition and extension.
• Natural sparkle.
• Good detail and airy.
• They aren’t shrill, sharp, or harsh.
• I didn’t heard sibilance, peaks, or coloration.
• Everything play very coherently in this region.
• Drum cymbals have good definition.

Soundstage:

• The soundstage I thought it was something average.
• Upper-mids forward diminish the sensation of depth.
• Part of the presentation is closer.
• The sound doesn’t present congested.

Imaging:

• Good instrumental separation.
• The stereo image is also good.
• Detailing and airy helps in instrumental separation.
• Good clarity to identify the place of each instrument.

Driver flex test:

• I didn’t notice driver flex sound when inserting the IEMs in the ear.

Amplification:

• Easy to push.
• It doesn’t need powerful amplifier.
• A simple dongle is enough.
• I used the FiiO KA11 for this review.
• I also used the Letshuer DT01 Pro.
• Both dongles did the job.
• Of course, the KA11 pushes better (more powerful).
• KA11 in 18 and the DT01 Pro in 30 (from 100 available on W10).
