Han Sound Audio Quentin Review

Han Sound Audio Quentin review featured

In this article, I’m reviewing the Han Sound Audio Quentin OCC IEM upgrade cable. Quentin is derived from a Latin word meaning “the fifth” which is apt because this is Han Sound Audio’s fifth-gen of pure copper cables. It’s priced at $486.

Han Sound Audio Quentin design


According to Han Sound, the biggest difference with Quentin compared to their previous pure copper cables is that the entire design is mainly based on a coaxial structure. Theoretically, this helps maintain the integrity of the audio signal by shielding it from external noise and interference and ensures consistent impedance along the length of the cable.

Han Sound mentions that graphene is incorporated into the material that surrounds and protects the conductors. The process involves interlacing graphene into the shielding material, creating a fabric-like structure that wraps around the conductors. Graphene is known for its exceptional electrical conductivity, strength, and flexibility. Its use in shielding can significantly improve the performance of the cable by providing a robust barrier against interference.

Quentin components

Quentin’s wires are 21 AWG which is thicker and has a higher current-carrying capacity than many conventional cables. The cable adopts an outer cloth jacket, similar to Han Sound’s flagship Torfa. Naturally, Quentin can be customized with many different connectors and terminations. My review unit came with 0.98mm 2-pin connectors and a 4.4mm plug.

Handling & Build Quality

I’m usually not a fan of fabric-covered IEM cables but in this case, I love the way the Han Sound Audio Quentin handles. Despite its thickness the cable weighs a mere 38.2 g and it’s extremely supple. Furthermore, there’s virtually no microphonics, even without using the chin slider.

Speaking of the chin slider, it’s a rich copper-coloured metal that contrasts nicely with the black fabric cover and the black components. The splitter and the plug both feature an octagonal pattern while the 2-pin cylinder housings are plain except for a red ring on the right side.

Quentin also features pre-formed ear hooks that protect your ears from irritation while safeguarding the cable cover from skin oils. They’re pliable enough to conform to the shape of my ears yet firm enough to guide the wire and I find the cable to be very comfortable overall.

As is always the case with cables in my experience, this upgrade cable isn’t about a dramatic overhaul. It’s about refinement.

The Quentin boasts Ohno Continuous Casting (OCC) copper, known for its purity and conductivity. The result? Clearer, more detailed audio that lets you hear the music breathe. In addition, there are improvements to the soundstage and layering, particularly regarding imaging.

But the Quentin isn’t just about microscopic details. It also adds a touch of air and crispness to the treble, akin to what you’d expect from a high-quality silver cable. Think sparkling highs and cymbals that shimmer without harshness. Bass gets a look-in too, with the potential for a tighter, more controlled low end, creating a solid foundation for the midrange and treble.

Think of it this way: Quentin is like adding a touch of high-end detail brushwork to a beautiful painting. It accentuates the existing brilliance without fundamentally changing the artwork itself.

So, is Quentin a revelation? Not necessarily a dramatic one. But for those seeking to unlock a touch more clarity, a hint more treble finesse, and perhaps a tighter bass grip, the Quentin might be the subtle upgrade your ears have been yearning for. Just remember, it’s about enhancing the journey, not rewriting the destination.

ddHifi Nyx Pro ($499)

Compared to the ddHiFi Nyx Pro, Quentin offers a different flavour. The Nyx Pro focuses on bringing out the power and depth in the bass, along with a wider soundstage. The Quentin prioritizes clarity and detail, highlighting subtle nuances in the music. If the Nyx Pro is a subwoofer adding punch to your music, the Quentin is a high-resolution monitor revealing every tiny detail. Both enhance the audio in their own way, so it boils down to whether you crave a powerful soundscape or a crystal-clear, analytical one.

Select Pairings

Spirit Torino IEM Twin Pulse Beryllium ($1,000) – This IEM (review here) has an eye-catching design with a sound equally unique. It’s mids-forward, warm, and full-bodied; yet, it remains copiously spacious and airy.

Paired with the Quentin cable, the TPB’s soundstage doesn’t expand in width, but it gains significant depth. The layering of instruments becomes even more distinct, further enhancing the TPB’s strength in precise imaging. Quentin exemplifies this strength, with instrument positions clearly delineated across the soundstage.

Itsfit Fusion ($950) – The Itsfit Fusion (review here) is one of my favourite custom IEMs in my collection. It strikes an enticing balance between body and clarity, impact and subtlety.

When paired with Han Sound Audio Quentin, the Fusion’s lows are tighter and more controlled. The bass extension is still there but the decays are crisper. The treble is more precise, aiding the instrument separation and black background which provides better imaging for a more immersive feeling.

I found the Han Sound Audio Quentin carves its niche by prioritizing detail retrieval without introducing any harsh brightness. It’s perfect for listeners like me who crave a touch more clarity, a hint more finesse in the treble, and perhaps a tighter grip on the bass. The Quentin could be the missing piece for my listening setup.

Beyond the sound, using the Quentin is a joy. It’s supple and tangle-resistant, making it a breeze to manage. The silver dots on the black background are a nice touch too – the cable looks great with any colour IEMs I pair it with. Overall, if you value a transparent and analytical listening experience with precise layering, Quentin is definitely worth an audition.
