Intro…

Todays mini review is of another set of 7 Hertz IEMs, the 7Hz Eternal.

If you don’t know what these mini reviews are, I suggest you check out the Timeless mini review (here), where I explain why I am doing these mini reviews. Again, I apologize for the lack of photos and the poor quality of the single photo I have included.

I would like to shout out to Android and Audio Discourse once more for sending me these IEMs to try out, it is much appreciated.


Presentation…

All I can say here is the same as I said with the Timeless, I can’t speak about the full presentation as I am not sure exactly what was included.

The box and the contents I have received are the same as with the Timeless, the only thing that has changed is the colour of the packaging (and the colour of the contents).


Build and aesthetics…

Again, these IEMs are almost identical to the Timeless except for the colour and one small aesthetical change. The faceplate of these IEMs is transparent and shows what looks like a driver through the glass (perspex?). However, this is not the actual driver, so it is really only a gimmick and I can’t say that I am overly fond of it.

The colour is a bronze colour instead of the black on the timeless, which I do quite like but I wouldn’t call them spectacular, in fact, I prefer the basic black of the timeless.


Sound…

I actually thought that these IEMs were another set of planar magnetics, an update to the Timeless. While I was listening to these, I was comparing them in my mind to the Timeless and I must say that I am not a fan. However, they are actually a set of dynamic driver IEMs but I am still not a fan.

The subbass is almost identical to the Timeless on paper, however, it sounds like it is less present, due to another part of the tuning that I will get to in just a second. This makes it seem like the subbass is quite rolled off and I found myself wanting far more than was given.

The midbass is the same story, it is almost a clone of the Timeless, yet the Eternal seems to have less to the ear. Again, I found myself wanting more. Yes, the bass boost on the Gryphon can remedy this but in a fair comparison, the Timeless wins and the S12 wins by an even larger margin.

The biggest problem with these IEMs, in my opinion of course, is the huge peak they have at 5kHz. I have said in the past that I seem to be quite sensitive to 5kHz peaks and the Eternal to me just sound harsh and even quite painful on occasions. I must say that I found this part of the frequency to be irritating at best and it really stopped me from enjoying these IEMs.

The details and soundstage I feel are just as good as on the Timeless, however, as I found the overall sound to be irritating, I wasn’t really paying much attention to the detail.


Conclusion…

So far I have tried three sets of IEMs in a row and I have to say that these have been the least enjoyable by a large margin. I found that I had to really make an effort to keep listening to them to make these brief impressions and in the end, I just gave up. I spent around a day with each of the other two sets yet the Eternal only managed to stay in my ears for about a couple of hours and that was enough for me to call it a day.

I’m sorry to say that I have not enjoyed the Eternal at all and would blindly pick either of the other two (or many many other IEMs) before choosing these.

That doesn’t mean everyone will hate them, we all have different tastes, but these are certainly not for me!
