The Penon Quattro IEM recently graced my ears, provided courtesy of the EU leg of the Audio Geek tour. Designed to cater to audiophiles seeking an immersive auditory experience, the Quattro promises enhanced sound isolation and a unique acoustic profile that we will explore through firsthand impressions.
Disclaimer: This IEM, Penon – Quattro, reached me as part of the EU leg of the Audio Geek tour. I would like to thank Penon and Sandeep, and subsequently Julian F.
Penon Quattro and Cable
The fit is good, but only under a condition. The deepening of the housing improves isolation. However, due to the same housing and nozzle, the body of the Quattro does not fully fit into my concha area, which is a rarity for me.
The cable is 4 cored, thick, soft and supple. It’s color is dark turquoise, and inside is black with a sizeable air vent.
Penon Quattro Sound
The sound stage is distant with the bass at the forefront. It plays naturally and smoothly. Don’t expect crispiness. It can be described as detailed. The tonality is okay. However, Fergie’s voice lacks the usual fluidity that it’s known for. Similarly, it falters in the treble range. Yet, the resolution is above average, with 3D imaging present in prominent vocals. In this frequency band, there’s a considerable transparency, such that even Garou’s commanding voice in the chorus gets support from a female vocalist distinctly.
The vocals flow with loaded tonality and even drift into harmony. Live recordings reveal the space around the soloist thanks to the Quattro. Its sound stage is broad, no doubt, and the bass contributes to the fullness of sound, whether it’s electronic or organic. It also passes the chaos control test. Summing up all technical aspects, aside from the vocals, it’s by no means a general-purpose monitor. It’s more suited for romantic evenings and dimly lit scenes.
Bass
With the Beatles’ “Maxwell’s Silver Hammer,” the bass foundation is impressive thanks to Quattro. Beyond that, they know their limits and don’t emerge unnecessarily. As “Sober” begins, they toe the line of bass distortion. However, generally, the basses that don’t go very deep are inherent in Quattro’s nature. Hence, I can’t claim it excels in genres like drum’n bass or dubstep. Yet, in ultra high gain and at 28/100 volume, the bass and effects are well-controlled in “Inferno,” making it a rich, four-minute 3D imaging experience.
Midrange
Not congested. But due to its dark timbre, it doesn’t sound very lively. And without sufficient power, the 3D imaging across the spectrum isn’t strong. When powered up, the vocals appear vivid and the articulation is solid. It captures all the tonality and nuances in the vocals. From this aspect, it’s fantastic for sitting down and boosting the torque to listen to solo singers. However, the most important negative point is lack of resolution on some instruments. And I have to admit that failing my master test in some midrange related aspects is disappointing. .https://deezer.page.link/KDVv2yvC26as3o7n7 I had seen him play kanun in a fashion like nobody else does, and naturally, it’s a solid comparison tool.
Treble
The treble is the weak point after fit. I mentioned its dark timbre. The trebles are present, not swallowed up, but it seems like Quattro has fallen out with them preventing any significant lift in the treble. Even in the ultra high gain setting on the M15S, I can’t get a vibrant playback. It seems, the IEM hardly gets past 10 kHz.
Comparisons__
I guess the only ideal matches for it would be Moondrop Variations and Campfire Andromeda for Penon Quattro according to my knowledge.
Vs Variations: The choice between these two would largely depend on your listening preferences for sure. If you prefer a sound that is warm with strong bass and less emphasis on high frequencies, the Penon Quattro would be more suitable. However, if you enjoy a more balanced sound with clear and detailed treble the Moondrop Variations would be a better fit. Both IEMs are crafted with high-quality materials and are designed to suit to audiophiles looking for premium sound experiences within similar price ranges.
Vs Andromeda: Whether one prefers the warmer, bass-forward sound of the Quattro or the detailed, balanced presentation of the Andromeda. Both are excellent choices in their respective styles and offer high-quality audio experiences for discerning listeners.

Penon Quattro Review Conclusions
The Penon Quattro offers a nuanced audio performance with a strong emphasis on bass and vocals, ideal for atmospheric listening in intimate settings. Its weaknesses in treble response and fit may deter those looking for an all-purpose audio solution or for use with more lively, high-treble tracks. Nevertheless, for those seeking rich vocal reproduction and controlled bass in quieter, more romantic settings, the Quattro might just strike the right chord. Its technical prowess in 3D imaging and soundstage broadness adds to its allure, making it a specialized choice for the discerning listener.
