Penon Quattro

Not gonna lie this combination looks hella cool

If you're interested in graph comparision, here's the Link

+ i'm a normal asian dude with some music producing background
+ i like clean balanced sound signature with focus on sub bass and lower treble, especially looking for a good dynamism and harmonic playthrough, i like vocal, not necessary mid dominant, can consider myself as treblehead
+ 60-68db listening session
+ Avarage score 4/10 (Quarks/ 7hz Zero) Middle score 6/10 (Tanchjim Kara)
+ Bias score is i like it or not, doesn't sum on overall score

- Bass (6/10): sound dampen, like you kick a blanket, slightly roll off bass (around 80hz ?), overall bass can be described as "vintage"
- Mid (6/10): if you have a thing for slow bpm genres, this could be it! (i don't)
- Vocals (7/10): fairly neutral with good position, sound strong and bold (heft maybe), lack some edge on high notes
- Treble (6,8/10): quite surprise that it resemblance to Timeless that i like without being siblance, might not have the same airiness and quick acting driver but very very close
- Detail (6,3/10): Macro (6/10), Micro (6,5/10)
- Soundstage (6/10): open sounding but poor vocal/instrument plancement that make the whole room feels concealed ----> imagine orchestra like sound stage with no windows, and a grouped up band that barely have enough volume to fill the whole room
- Imaging (5/10): good stereo
Bias (7/10): Warm neutral
Overall : 6/10
Very vintage, very natural sounding, it sounds like old standing speakers without subwoofer. If your library consist of slow bpm genres then Quattro could be the best iem that you'll every heard.

Disclaimer​

The Penon Quattro IEM is part of a review tour organized by A.G. and Penon in my country. The sample unit was provided by the brand for evaluation purposes. I had the opportunity to assess the Penon Quattro for a duration of seven days. This review is entirely based on my personal experience with the product, and all opinions expressed herein, whether positive or negative, are solely my own and are not influenced by any external parties.

Bass: Robust, Substantial, and Rich​

The Penon Quattro IEM delivers a bass that is robust, substantial, and rich, providing a deeply satisfying low-end experience. The texture of the bass is irresistibly engaging, making every beat and note a pleasure to listen to. This feature makes the Quattro IEM ideal for genres that demand powerful bass, such as jazz and electronic music.

Midrange: Silky and Accommodating​

The midrange of the Penon Quattro is silky and accommodating, ensuring a smooth and enjoyable listening experience. The mids are well-balanced, providing clarity and precision to vocals and instruments. Female vocals, in particular, are rendered beautifully, while male vocals could benefit from a bit more thickness to achieve a fuller sound.

Treble:​

The treble performance of the Penon Quattro IEM sets it apart from its predecessor, the Serial. The treble is airy, well-extended, and adds a sparkling quality to the overall sound signature. For listeners who appreciate detailed high frequencies without compromising musicality, the Quattro excels in delivering a refined treble experience.
The treble is characterized by its smoothness and non-fatiguing nature, with a soft decay that contributes to a pleasant listening experience. Unlike the bass, which is more dominant, the treble functions as a supportive element within the overall sound profile, imparting a delicate and nuanced quality

Soundstage: Expansive Horizontally​

The soundstage of the Penon Quattro is impressively expansive in the horizontal dimension, creating a wide and immersive audio environment. This spatial quality enhances the listening experience by making it feel as though the music surrounds you.

Design: An Exquisite Work of Art​

Visually, the Penon Quattro IEM is an exquisite work of art. The design is sleek and elegant, with a build quality that feels both premium and durable. This aesthetic appeal is complemented by practical features, making the IEM not only a pleasure to listen to but also a joy to look at and use.

Technical Performance: Room for Improvement​

While the Penon Quattro excels in many areas, it is not the most technically precise IEM available. Additionally, to truly unlock its full potential, these IEMs require powerful sources. When paired with the right equipment, the Quattro can deliver an outstanding audio performance. For example, when I change the source of DAC from RU6 to Fiio Q5s, it extends the the performance so much.

Penon Quattro- an IEM that harmonizes musicality, relaxation, and exquisite aesthetics

The Penon Quattro envelops listeners in a cocoon of sonic delight. Its bass, thick and textured, beckons like a warm embrace, while the midrange unveils lovely angelic vocals—gentle whispers that linger in the soul.

The Penon Quattro is an in-ear monitor (IEM) that seamlessly blends musicality, relaxation, and exquisite aesthetics. If you prefer a warm, smooth sound signature with a focus on mid-bass, the Quattro is the ideal choice. Let’s dive into its performance across different aspects:

*Important note: Remember, audio preferences are subjective, and what matters most is how the IEM resonates with your personal taste.

Bass:

The Quattro’s bass is a soul-stirring experience. It rumbles deep within, enveloping the listener in warmth. It’s thick, textured, and immensely enjoyable.

While it lacks the agility for extreme genres like rock or metal (which demand lightning-fast bass attack), it excels with genres that benefit from a more relaxed, punchy bass. Drums sound particularly satisfying.

Midrange:

The Quattro’s midrange steals the spotlight. It produces angelic vocals that tug at your emotions. Listening to it can become addictive.

However, it’s not ideal for complex classical compositions with multiple instruments playing simultaneously. The midrange shines brightest when vocals take center stage.

Treble:

The Quattro’s treble distinguishes it from its predecessor, the Serial. It’s airy, well-extended, and adds sparkle to the overall sound.

If you appreciate detailed highs without sacrificing musicality, the Quattro delivers.

Technical Performance:

The Quattro prioritizes musical enjoyment over analytical scrutiny. It won’t dissect every micro-detail, but it will immerse you in a captivating sonic journey. Some other IEMs in this price range may offer more analytical precision, but the Quattro’s allure lies in its overall musicality.

Layering and Clarity:

While not hyper-analytical, the Quattro maintains good layering and separation.

Instruments and vocals occupy distinct spaces, contributing to an engaging listening experience.

Emotional Vocals:

Female vocals also shine, with a delicate sweetness that tugs at your emotions.

Whether it’s soulful ballads or heartfelt acoustic tracks, the Quattro’s midrange delivers an emotional connection.

Smooth and Forgiving:

The Quattro is smooth, forgiving, and easy on the ears. It doesn’t emphasize harshness or sibilance.

Male vocals, in particular, sound lush and intimate. For example, Andrea Bocelli voice on the Quattro sounds charming and somewhat addictive. The midrange draws you into the heart of the music.

For those seeking pure musical pleasure, the Quattro is an extremely fun and enjoyable set.

In summary, the Penon Quattro harmonizes musicality, relaxation, and aesthetics, making it a delightful choice for music lovers. .
