Design

The Allure has silver-coloured aluminium alloy shells with a matte finish. Its faceplates have a green and black pattern with a glossy finish. There are 2 small vents: one near the base of the nozzle and another in front of the 0.78mm 2-pin socket.

I find the Allure extremely comfortable in my ears and I can happily wear them for hours on end. They have good passive noise isolation too, so you can enjoy your music without distractions.

The cable has a black and green fabric sheath that matches the colour of the IEMs. It feels sturdy and has all metal components. There are no significant microphonics and the cable handles well.

Sound

Gear used for testing includes the Hidizs XO, Shanling M5s and SMSL C200. This is an efficient IEM and doesn’t require a powerful source to perform well.

The KiiBoom has a mild V-shaped sound signature with a neutral-bright presentation. It has a spacious sound with excellent clarity and abundant detail. The soundstage is wider than it is deep and the air between instruments and vocals is clear, facilitated by strong instrument separation.

Bass

The discernment of Allure’s bass can pose a challenge. It alternates between noticeable heft and subtle restraint. However, its character lies in being tightly controlled, devoid of any smudging or overpowering tendencies.

The bass notes offer satisfying impact and texture, delivering a sense of rapidity and accuracy. This quality coexists with a substantial lack of upper bass presence, culminating in a sometimes inconsistent tonal balance and absence of weight.

Midrange

The midrange of the KiiBoom Allure IEMs is characterized by remarkable clarity, offering an expansive and lively feel. Vocals are especially well-defined, although male vocals might be perceived as slightly lacking in weight.

The upper midrange exudes some shoutiness. Certain sounds such as the crescendo of strings or the heightened harmonics in female vocals, while vibrant, can evoke an aggressive quality in this frequency range.

Treble

The treble in the KiiBoom Allure IEMs is characterized by its clear and intricate nature, all without any harshness or hissing sounds. Rather than being forceful or upfront, it complements the already pronounced upper midrange, resulting in ample clarity.

The treble gradually fades, maintaining a strong top-end extension. This means even crash cymbals sound smooth. People sensitive to treble should find comfort in the Allure’s presentation, but those who are bothered by a bright upper midrange might face challenges.

Verdict

In conclusion, the KiiBoom Allure delivers a well-rounded sonic experience characterized by a mild V-shaped sound and a neutral-bright tonal profile. Priced at $99, it offers solid value for its performance. The expansive soundstage, coupled with exceptional clarity and strong instrument separation, ensures immersive listening.

While the bass showcases a dynamic interplay between impact and restraint, maintaining control and precision, the midrange captivates with its expansive clarity. However, it’s worth noting that the upper midrange might occasionally verge on a shouty quality, particularly with elements like crescendo strings or heightened harmonics.

The treble complements the upper midrange, contributing to the overall clarity without introducing harshness. It gently extends into the top end, ensuring smooth sound reproduction, even with challenging instruments like crash cymbals. Treble-sensitive listeners will appreciate its approach, though those sensitive to a bright upper midrange should exercise caution.
