Both models offer a thoughtful unboxing experience, complete with accessories that support comfort and compatibility. Campfire includes a few more creature comforts, while FlipEars focuses on durability and customization.

Design & Functionality

Aesthetically and ergonomically, these two IEMs offer distinct design philosophies. The Zurq XXIV sports a bold visual identity with glittery orange shells and a semi-transparent grey body, offering a peek at the internal tribrid driver array. However, the housing is relatively bulky, and the large nozzle diameter may be a challenge for smaller ears or those who rely on third-party eartips. The Bonneville, by contrast, features a sleek, ergonomically contoured shell designed for a universal fit that mimics the feel of custom molds. Though it also leans on the larger side, its more refined shape and standard-sized nozzle give users more flexibility in achieving a secure, comfortable fit. Both IEMs are built with attention to detail and durability, but Campfire edges ahead in long-term comfort and ease of eartip customization, while Flipears offers a visually striking design with an audiophile-focused 4.4mm cable as standard.

Technical Specifications

Specification	Zurq XXIV	Bonneville
Driver Configuration	Tribrid Design: - 2 Electrostatics - 3 Balanced Armatures - 2 SoniXwoofers	Hybrid Design: - 10mm Dynamic - 3 Balanced Armatures
Frequency Response	5Hz - 70kHz	5Hz - 20kHz
Impedance	20 Ω @ 1kHz	29 Ω @ 1kHz
Sensitivity	116 dB	94 dB

Technically, both models are hybrid marvels, though they diverge in configuration and tuning philosophy. The Zurq XXIV boasts a seven-driver tribrid setup, combining two electrostatic drivers, three balanced armatures, and two SoniXwoofers (dynamic drivers) for an ultra-wide frequency range of 5Hz–70kHz. It also offers a low 20Ω impedance and high 116dB sensitivity, making it easier to drive from portable sources. The Bonneville , with a more traditional four-driver hybrid setup (10mm dynamic + 3 BAs), offers a more grounded frequency range of 5Hz–20kHz, 29Ω impedance, and a sensitivity of 94dB. On paper, the Zurq provides more headroom and output efficiency, while the Bonneville focuses on clean, controlled delivery through a more conservative driver arrangement.

Listening Review

Soundstage and Imaging

When it comes to soundstage, both IEMs deliver immersive, three-dimensional experiences—but in very different ways. The Zurq XXIV paints a wide, expansive stereo image with strong lateral separation and depth, creating a cinematic sense of space. Its layering feels light and airy, especially with large-scale arrangements, though it slightly lacks in vertical dimension. The Bonneville , meanwhile, offers a slightly more compact but tighter stage with better spatial control. Instruments are precisely positioned, and its stage expands outward with a natural sense of immersion, aided by excellent isolation. While the Zurq emphasizes size and atmosphere, the Bonneville prioritizes accuracy and coherence—making both equally engaging depending on your listening style.

Bass Response

Bass performance on these IEMs showcases their unique tuning identities. The Zurq XXIV leans into a weighty, dynamic low end that provides a thick, impactful foundation without muddying the mix. Its bass is tuned with warmth and extension, offering satisfying subbass rumble and midbass punch. On the other hand, the Bonneville delivers a more restrained but surgically precise bass response. Its 10mm dynamic driver is fast, clean, and balanced—producing just enough subbass presence to ground a mix without dominating it. Both IEMs transition smoothly from lows to mids, but where the Zurq adds color and drama, the Bonneville keeps things tight, clear, and tonally refined.

Midrange Performance

The midrange is where the most contrast between the two emerges. In the Zurq XXIV , the mids are slightly recessed, lending a subtle U-shaped signature. Vocals and melodic content sit further back in the mix but remain clean and well-layered, encouraging focused, intentional listening. This creates a sense of space but can sometimes feel hollow depending on the track. Conversely, the Bonneville pushes the midrange forward, especially vocals and lead instruments, making them the emotional core of the sound signature. It offers outstanding texture, layering, and presence, without sounding overly aggressive. Where the Zurq’s midrange is more atmospheric and analytical, the Bonneville is more direct and emotionally engaging.

Treble Detail

Both IEMs exhibit excellent treble tuning, but their presentation differs in flavor and texture. The Zurq XXIV utilizes electrostatic drivers to deliver a crisp, airy top end with refined extension. Its highs shimmer without harshness, balancing clarity and comfort to avoid fatigue even during long sessions. Meanwhile, the Bonneville delivers a similarly bright and articulate treble, though with slightly more natural decay and tonal cohesion. Cymbals, strings, and high vocal harmonics are rendered with delicacy and ease, contributing to an effortless sense of clarity. While the Zurq's treble feels ethereal and open, the Bonneville brings a slightly more grounded and integrated feel—both equally compelling but differently tuned.

Final Thoughts

The Flipears Zurq XXIV and Campfire Audio Bonneville both earn their place in the premium IEM category with unique sound signatures, high-end builds, and thoughtful accessories. The Zurq offers a grander scale with expansive staging and impactful low-end energy, making it an excellent choice for listeners who enjoy cinematic, bass-forward presentations with refined top-end sparkle. The Bonneville, on the other hand, delivers an intimate, emotionally engaging sound with forward mids and crisp, natural treble—perfect for vocal and acoustic-focused genres.

Neither IEM feels superior in all categories; instead, they reflect two distinct philosophies in high-end tuning. For those who crave spacious soundscapes and energetic dynamics , the Zurq XXIV shines. For listeners seeking refined clarity and a mid-centric, detailed profile , the Bonneville may be the perfect match.
