7Hz Timeless Vs Timeless II Comparison Review

The 7Hz Timeless was a game-changer in the world of planar magnetic in-ear monitors (IEMs), offering exceptional detail and clarity at a competitive price. Now, with the release of the 7Hz Timeless II, the brand promises an even more refined experience with upgraded materials, a redesigned driver system, and interchangeable nozzles for customizable tuning. But does the Timeless II truly outperform its predecessor, or is the original still the better pick for certain listeners? Let’s break down the design, comfort, soundstage, bass, mids, and highs to determine which model deserves a spot in your collection.

What You Get

Look & Feel

Everything from the shell design to the cable feels like an upgrade from the original. The first Timeless looked different compared to most other IEMs that were out at the time, which the Timeless II refines. Its new carbon fiber faceplate makes the original seem cheaper in comparison, boosting its value and build quality. The new 2-pin cable is also much superior to the original’s, giving you a much more premium package for the price. Since not much is changed about the actual size and structure of the shell, the fit remains the same for both versions of the Timeless.

Design

Both versions of the Timeless have planar magnetic drivers, with the Timeless II being slightly bigger than the original. This is only by the difference of 14.2mm vs 14.5mm. They both have a dual-sided diaphragm, but the new version is said to be more advanced, being coated with a specific material. This is how 7Hz hopes to replicate a signal’s transients, but the Timeless II adds an additional 7-layer drive enclosure that stabilizes it. You also get a new nozzle system with the Timeless II that allows you to switch between four different tuning methods. While a very interesting concept, I can see some being turned off by having to unscrew tiny nozzles to get the sound signature they want.

Soundstage

Listening to both Timeless IEMs back and forth, it’s hard to determine which one has the better soundstage. Both the Timeless I and II have great imaging, with neither being very wide but containing good depth. Localization might be a bit more precise on the Timeless II, though. I also felt that the headspace might have been a bit more open, but your source plays a big role. For instance, I started listening on a Fiio BTR17, but the sound really opened up on the Timeless II when I was curious about how they would sound coming through a Chord Mojo 2. Sound feels elevated through both versions of the Timeless, but the Timeless II has elements that may appear taller in the mix.

Low End

The Timeless II’s interchangeable nozzles give the sound signature a ton of variety, and are already a huge advantage over the first version. If you simply don’t want to deal with all the nozzle configurations, then the original Timeless has a strong enough bass to satisfy you more easily. However, the Timeless II supplies a ton of variety in its frequency response it’s hard to pass up. If you want to hear the perfect combo of sub and mid-bass impact, you’ll want to attach the gold dome nozzles on the Timeless II. This outperforms the Timeless I in many ways, such as frequency separation and tonal weight.

Mids

With the first Timeless, the midrange was neutral and flat, and certain nozzles on the Timeless II share that response. The standard nozzles feel a bit more roomy in the mids than the Timeless I, but both versions are almost equal in terms of timbre. When you start switching up the nozzles though, the Timeless II gains a ton of ground in the mids. The gold and silver domed nozzles add a ton of weight to notes, and the details are more revealing. The detail on the original Timeless is good, but the Timeless II unfolds new layers and feels more transparent.

Highs

Even with the many nozzles of the Timeless II, I found myself enjoying the airiness of the first Timeless more. Neither of the nozzles on the Timeless II gave you that glistening brilliance that adds color and height like the first one can. It’s quite surprising since I still thoroughly enjoy the highs on the Timeless II, especially with the gold and silver domed nozzles that give the highs a lively sparkle. The Timeless II is very balanced with its highs, whereas the Timeless 1 pushed them a bit more forward and gave them a crisper presence.

Summary

Both the 7Hz Timeless and Timeless II deliver impressive planar magnetic performance, but the Timeless II elevates the experience with a more advanced driver enclosure, improved tuning options, and a higher-quality build. While the original Timeless still holds its own, especially in the treble response, the Timeless II offers more versatility with its interchangeable nozzles and refined midrange clarity. If you value customization and a richer, more immersive sound, the Timeless II is the clear winner. However, if you prefer a more straightforward tuning with a slightly airier treble, the original Timeless remains an excellent option. No matter your choice, both IEMs showcase 7Hz’s commitment to high-quality planar sound at a competitive price.
