7Hz Eternal Review




The 7Hz Eternal is a dynamic driver in-ear that features the same shell design as the very popular and well-received, including by myself previously, planar magnetic-based Timeless. The two share a lot of similarities outside just the basic shell design. The cables are nearly identical, as is the box and accessories, outside of the color changes for each. The Eternal features a reddish/bronze look across the board, with an interesting ultra-glossy decal insert faceplate, while the Timeless sticks with a very netural black and white with red accent look.

In addition to just the cosmetics, the two share very similar sound tuning, which I'll cover here shortly. The Eternal runs for $249 USD, just a bit more than the Timeless does, and both can be purchased on Linsoul.com, who shared these review units with us for review.

Sound Impressions

The Eternal takes on a very similar tonality as its predecessor Timeless. It's a balanced sound signature with emphasis in the sub-bass and a slightly bright upper mid-range and low treble. In general, this is a very likeable sound signature for my personal tastes, and I think it does well as a good all-arounder for most genres of music.



The Eternal's use of dynamic driver perhaps shapes its technical performance a little differently than the Timeless does. While an initial glance at their FR shares a lot of similarities, there are just slight differences in how they are tuned that make the Eternal sound a touch warmer. Perhaps it is the dynamic driver's slightly longer decay, or its reduced upper treble in comparison to the Timeless. Either way, the Eternal has a little more low-end body and meat. The Timeless is punchier to me though, with more impact. 


The mid-range is good. I actually enjoy my time with the Eternal thus far, and as you may know, mid-range is important to me. The Eternal has an equal emphasis on male and female vocals, but does have just a slight occasional jarring brightness in the upper-mids, on the very rare poorly recorded master. That said, I don't find the Eternal to be distracting nor sounding wrong. It sounds good, if not a little subdued, especially when comparing to the Timeless which is slightly brighter and more dynamic in its sound shaping.



The Eternal's treble can be considered a little darker than neutral, but overall, it exhibits a very relaxing and warm sound. I think this gives it the ability to listen for a long period of time, and if you found the Timeless to be a tad bright and fatiguing, the Eternal may be a good compromise here, with slightly less treble, but very comforting in its approach.

Final Thoughts

The Eternal may not have the best looking aesthetic for my tastes, but it does make it up with a good solid-performing sound signature, and decent technical performance. It's not the best in-class, but its an above-average performer and I think is a good addition to the market. Timeless owners probably won't benefit much from going after this one, unless one was concerned with the brighter treble response of the Timeless. In that case, the Eternal may suit one's tastes more.

  1. Do you hear that massive 5k spike? Some other reviewers don't like the Eternal because of this.
