Look & Feel

If you initially found the original 7Hz Timeless somewhat odd due to its shall design. 7Hz doubled down on that design for the Timeless II, and adds a new carbon fiber finish to it. This gives the Timeless II a new aesthetic theming that makes sense for its new refinements and systems. It certainly shoots above its price point in terms of its style, especially when paired with its new stock cable which is now a 2-pin 4-core ultra pure 7N single-crystal copper cable. Everything about the look of the Timeless II is upgraded from the original, however, the fit remains unchanged. The Timeless II fits in my ear just fine, but isolation isn’t the greatest. It heavily depends on what tips you use, whether or not the Timeless II has a good seal, and the stock tips might not do that for you.

Design

The Timeless II uses a slightly modified 14.5mm planar magnetic driver. It brings the first dual-sided coated diaphragm, which is implemented to enhance the response of the driver. It also uses a 7-layer drive enclosure that gives the driver more stability. What’s going to stand out the most about this design is its unique tuning system. The Timeless II isn’t the first IEM to do this, but I’m surprised by just how much variety is offered. It comes with four different unscrewable nozzles that change up the sound signature of the Timeless II. No matter what nozzle you choose, the Timeless II provides a good amount of power from balanced and unbalanced sources. I used an Astell & Kern HC4, which provided enough power to the Timeless II to give it ample headroom and synergy.

Soundstage

With its interchangeable nozzles, the 7Hz Timeless II can be heard in many ways. However, no matter which tuning you prefer, the soundstage and imaging are consistent between changes in timbre. At first, I was a bit surprised at how limited the Timeless II was in width, but that’s not where the soundstage shows its depth. While its wingspan might feel a bit too narrow, the way it presents layers of sounds is very impressive. It keeps the sounds from appearing on a too flat a plain, while also organizing them in easily localized positions throughout the mix.

Each layer stacks under and over each other effortlessly, creating a stereo field that has a cavernous space with great separation. The spatial imaging allows for a more open headspace than most IEMs in this price range, making the sound appear much bigger than it is. While the Timeless II might not have a wow-factor in its soundstage, the stereo image is extended exceptionally well.

Low End

The Timeless II comes with its gold standard nozzle, which is the tuning method I listened to first. Right from the start of my testing, I was already hooked on this nozzle’s satisfying rumble and body that I couldn’t imagine changing them. The frequencies aren’t very dominant, but they have a clear depth and presence that maintains physicality while keeping them separate from the mids. This is the bass you want for balanced notes and realism, while also dabbling in a bit of flavor. It’s normally the bass signature I like, but at some point I had to see how the other nozzles switched things up.

I screwed on the silver standard nozzles next, which has a few benefits, but also some exceptions. If you thought the gold standard nozzle didn’t have enough oomph behind it, the silver will have what you’re looking for. The sub-bass foundation of the low frequencies has a much wider resonance, emanating like a bloom effect. It still has that deep rumble from the gold, but its spread is much more significant. In turn, this softens the solidity of the mid-bass frequencies though, which have less physicality when it comes to notes.

If you want to hear the mid-bass really come alive, I would suggest the gold dome nozzle. All the body and richness the Timeless II has to show is here, while also maintaining a consistent sub-bass lift. Bass notes are thumpier, while also showing finesse. The silver dome nozzle has a similar response, but is slightly subdued. If the gold tends to exaggerate some of its bass frequencies to add flavor, the silver helps even things out.

Mids

With the gold standard nozzle, the mids are detailed and roomy. There’s a clear breath to them while also not appearing the most full or lush. It’s a perfectly neutral timbre that offers enough texture to its surface to make instruments stand out individually. When switching to the silver standard, the mids are emphasized in the upper-midrange, highlighting the strike on piano keys and putting an accent on them. The timbre doesn’t resolve as well, but its sharpness underlines strings and female vocals quite well.

If you’re missing some weight in your midrange, switch over to the gold dome nozzles. While the low mids might feel the most aggressive at first, the whole midrange keeps up the energy with more refined detail. Instruments have a much more defined shape to them, and notes strike a bit harder. While the silver domed nozzle maintains this weight, you lose a bit of that impact. However, the frequencies seem to resolve better, like an additional layer is unfolded that can be heard when listening to recorded instruments in a live room. Artifacts and microdetails rise to the surface, and the timbre becomes very lively.

Highs

The gold standard gives you the best control and balance in the highs, while also delivering satisfying texture. Sound elements sparkle and sizzle well, with a crisp edge that only slightly peaks. Switching to the silver standard reveals a more raw timbre to the highs, still not reaching anything harsh. It’s a bit more aggressive than the gold, but keeps its sharper qualities more subtle.

With the gold dome nozzle, the highs are super clear. Their resolution is where the Timeless II feels the most natural and lush. The highs display better technical ability, while also buzzing and sizzling with excellent resolve. It’s not the kind of treble you hear very often in IEMs at this price point. The silver domed nozzle has almost the same level of sparkle to it, but with added height and even slightly more transparency.

Summary

The 7Hz Timeless II transcends the limitations of its predecessor by incorporating innovative design elements and advanced audio technology, making it a compelling choice for both casual listeners and serious audiophiles alike. Its interchangeable nozzles allow users to tailor their listening experience, creating a unique sound signature that fits individual preferences. The high-quality materials, together with the well-balanced sound across all frequency ranges, position the Timeless II as an exceptional value in the realm of premium IEMs. If you’re searching for a dynamic audio companion that combines style, versatility, and performance, the 7HZ Timeless II should undoubtedly be on your radar.
