7hz Sonus - A Refreshingly Pure Hybrid

Intro

Here I stand, face-to-face with the 7Hz Sonus, a brazen ode to minimalism in a world where more seems to be the mantra. One dynamic driver, one balanced armature - that’s all it takes for 7Hz to throw down the gauntlet. They’re saying, “We don’t need a dozen drivers for greatness, just the right ones, perfectly tuned.” It’s like they’ve taken a step back from the driver arms race and said, “Let’s master the essentials first.” This, my friend, promises to be the epitome of a pure hybrid. No excess, just raw audio power packed into a tiny package.

And the audacity doesn’t end there. 7Hz isn’t aiming to break the bank while they’re at it. They’re gunning for that sweet spot where quality meets affordability. It’s a daring endeavor, and one that’s piqued my interest. Can they really nail it? Can they give us a taste of sonic perfection without demanding our firstborn in return? Well, that’s what we’re here to find out. So, hold on tight, because this ride promises to be anything but ordinary. Get ready to meet the 7Hz Sonus.

Pros & Cons

Package & Accessories

• Sleek faux leather pouch
• 3 pairs of blue silicone tips (Small, Medium, Large)
• 4 pairs of white silicone tips (Super Small, Small, Medium, Large)
• Nozzle filters in a charming petal pattern as well as traditional all-black style
• A flat cable equipped with four strands and a 3.5mm golden-plated connector

The 7Hz accessories package for this IEM is virtually an extravaganza - generous, but somehow still leaves you wanting. Those eartips, oh so abundant in number, but their quality? Well, that’s up for debate. They flaunt their bright colors like they’re auditioning for a fashion show, but don’t be fooled, there’s more flash than substance here. Now, the nozzle filters, they’re the unsung heroes of this ensemble. No fuss, no frills, just reliable function.

And then there’s the cable - a divisive character, to say the least. It boldly flaunts its flat design and plasticky demeanor, a move that’s sure to spark love-it-or-hate-it debates. This cable is destined to have staunch defenders and fierce detractors. So, as we sift through this assortment, it’s clear that 7Hz aimed for a mix of pizzazz and practicality, even if it comes with a side of controversy.

Comfort & Fit

Despite the capsules’ plumpness, they manage to provide a considerable dose of comfort. Insertion is a breeze, especially when paired with the correct pair of eartips, which in all odds, are not the ones in the package. Once in, they hug ears with a seal so tight, not even a whisper of movement or rotation dare disturb the peace.

Now, about that nozzle - it’s an unfortunate case of “almost could, but didn’t.” This might spell trouble for some, depending on how deep you manage to go. In my case, with a relatively shallow insertion, it’s smooth sailing. Yet, as time marches on, a subtle discomfort emerges, a reminder that even the most comfortable IEMs have their quirks. Perhaps if the nozzles were a tad longer and less compressed, the comfort wouldn’t be such a tough nut to crack.

As for the flat over-ear cable, it’s fine. Lightweight and unassuming, it plays its part well. However, it’s not a complete victory due to the details mentioned earlier. It’s like having the perfect Sunday brunch, only to discover they’re out of avocado. A minor disappointment in an otherwise pleasant experience.

Lows / Bass

Let’s talk about that bass, shall we? The bass for this IEM is clean, crisp, and oh-so-disciplined, it knows its place - no trespassing into the sacred realm of mids. Now, we’re not talking about a bass that’ll shake the earth beneath you. This isn’t about rumble or rubbery feels. It’s about agility, freedom, and a touch of sophistication.

The sub-bass is a thing of beauty, hitting the right notes and hitting them well. Step above, and you’re met with naturalness and realism that’ll make your ears feel good.

Now, let’s get descriptive. This bass doesn’t just play, it narrates. It’s crisp, it’s resolute, and it defines its territory with precision. But it doesn’t come with the weight of a lead brick. This isn’t your ticket to basshead paradise, though.

Let’s not forget, this bass knows how to behave in a crowd. It handles complexity like a seasoned pro, never missing a beat, never getting lost in the chaos. So, if you’re into bass that’s as refined as it is reliable, you’ve found your match.

Mids / Vocals

The midrange is where the action truly unfolds. 7Hz pulls off a little magic trick here, slicing off the bass from the initial midrange. The result? A lean, mean midrange machine. Clarity, transparency, and definition are the order of the day, amped up by 7Hz’s custom BA driver, serving resolution, definition, and detail in generous portions.

Now, let’s talk contrast. The low-mids start the show, smooth and slender, like models on a runway. Then, enter stage right, the high-mids, with a flair for the dramatic. They are not shrill, just heavy. That said, yes, there’s a touch of sibilance and a little sharpness.

For those seeking velvety, nuanced mid-highs, well, you might want to look elsewhere. The Sonus are unapologetically clear, clean, and bright for the vocals.

Highs / Treble

The treble for the 7Hz Sonus is a peculiar creature. There’s a certain restraint here, a touch of elegance that keeps them from going overboard. Yet, they’re not shy about making their presence known. They strut to the forefront with a moderate swagger, demanding attention and refusing to be ignored. These high notes are distinct and distinguished, adding a touch of sparkle to the overall experience.

Now, when it comes to instruments, they add a vivacious energy, but it’s a bit like trying to tame a wild stallion. There’s a wildness, a rawness that can border on the edge of unruly. And again I will point to the BA driver as a culprit. Yet, in the grand scheme of things, it’s a minor quibble.

And let’s talk about that incisiveness - it’s present, but it knows its boundaries. 7Hz did the separation of the parts in the sound spectre well for this model. It dances on the edge, but it never crosses the line into piercing territory. This is treble that knows how to make an entrance without overstaying its welcome.

Conclusion

Alright, let’s cut the fluff and get straight to the point. The 7Hz Sonus? It’s a beast. One dynamic driver, one balanced armature - and they’ve nailed it. The bass? It’s like a sprinter, lightning-fast and leaving no trace behind. It starts high and plummets down, delivering a punch that can leave you wide-eyed if you’re new in this hobby, but it’s never violent or aggressive. And the mids? Transparent, sharp, and detailed.

The treble is also notable and it’s not here to play games. Energetic, crisp, and stretching for the stars. The soundstage might be narrower than I expected, but it’s not a sad case either. And separation? It’s just about as good as I’ve hear from this kind of driver configuration.

So, if you’re after an analytical set with a solid bass foundation, look no further. The 7Hz Sonus isn’t just an IEM, it’s a statement. It’s a reminder that sometimes, less is more - and in this case, less is damn near perfect.
