==THIS POST IS FOR==
==MY DAILY DRIVERS==
==LET'S GET STRAIGHT TO IT==Unboxing:
These IEMs in the 800k IDR price range surprisingly come with not just sufficient but also unique accessories. From the cable, ear tips, to the display in the box, I found them quite interesting. Contents:
Fitting:
I initially thought these IEMs were made of metal because of the shiny faceplate, but I was wrong. These are full plastic resin IEMs, very lightweight. The 1 DD + 1 BA configuration, which I thought would be bulky, turned out to be quite thick but still comfortable and sat nicely in my ears. Moreover, the standard length and width of the nozzle make fitting these IEMs in the ears easy.
Bass:
The first time I listened, I immediately understood why these IEMs are a favorite among entry-level hobbyists. The natural bass thump from the Sonus feels more natural compared to other IEMs in its price range. It's not a punchy bass that goes down to the Mariana Trench, but you can feel the power that's engaging enough to be categorized as fun. Personally, I would prefer if the power were increased. The sub-bass has a short impact, so there’s no long rumble that, if it were present, would give a grander effect to each song because these IEMs have a fairly airy sound tuning.
Oh, forgot to mention, the presentation of the bass and sub-bass is very good, positioned on the outer part of the entire sound spectrum, making the music more enjoyable.
Mid:
Vocals with a fairly forward presentation are also a strength of these IEMs. Regarding positioning, the vocals are right in the center, airy and wet without being overdone, but in my opinion, a bit thin. For those who like male or female voices with low tones, these might not be suitable as they lack the soul of the music. But for vocals in pop songs or those relying on mid to high tones, they will feel very enjoyable. There is no sibilance or shoutiness in the mid tuning of these IEMs affecting the vocals.
Treble:
The treble is tuned safely without any piercing sensation. You can clearly hear the tinkling of guitar strings or percussion instruments, making these IEMs have quite an extended treble for their price range. Unfortunately, I feel the sound is not clear enough as there is some sibilance in the upper mid to treble range, especially with distorted guitar sounds or piano notes, which is somewhat disturbing in some songs. Additionally, I do not feel the sparkling treble in these IEMs, so it’s clear that they are not for treble heads and do not feel special.
Clarity:
The upper mid to treble range, especially the guitar plucks, feels sibilant, particularly in the tail of the plucks. This is noticeable in some songs, making the sound feel less clear. On the plus side, the micro-details produced by these IEMs are among the best in their class.
Soundstage:
Above average. The airy sound gives a spacious impression of the soundstage, complemented by good instrument positioning. Unfortunately, if the sub-bass rumble were longer, it would feel grander.
Imaging:
Excellent 3D imaging for its price range because the instrument positioning is spot-on and clear. Instrument separation is clear for pinpointing each instrument. I love the technicality of these IEMs.
==COMPARISON==I compared them with similarly priced IEMs, the Celest Pandamon 2.0 and Kefine Delci. Yeah, both are about $10 more expensive, but that's okay. Here we go:
==CONCLUSION==
That's all.

Introduction/Overview to the IEM
Manufactured by 7HZ, the sonus is a Hybrid driver iem sporting 1BA alongside 1DD. Releasing at an MSRP of ~$60 USD it targets the Truthear Zeros and Hexas of the world and they do truly challenge the reign of the Truthear Zero.
Unboxing - Accessories
The unboxing experience and the amount of accessories is great for the price range, they are packed very well with a sleeve covering the main box in which the main box opens to reveal a paper insert that greets us to the 7HZ world and their products, under the insert are the iems theirselves packaged in a thick foam that insures they arrive safely
The accessories that are bundled with the iems for this price range are very good, consisting of a set of 4 filter and mesh replacements. a good selection of tips , a "leather" carry pouch that sports the 7hz logo
Included is the cable which is a 4 core unbraided cable. although this looks great it can be a issue for comfort and other reasons since i find it easier to snag this on objects such as clothing and just generally more rigid and less forgiving than other cables on the market. it is also a 2pin 0.78 cable so it can be interchangable used with other iems if one may wish to. just getting the picture below was more difficult than it should be due to the nature of this cable.
The eartips that come with the sonus consist of the generic 7HZ coloured tips in a neon green bag and some black and red translucent tips which are firmer than others i have tried.
Thats enough of the accessories and unboxing, lets get to the fun part, the sound.

Tips: Final Audio Type E
Using these IEMs for around a hour you realise how good the fit is, whilst the majority of iems are generic shells, these conform to your ears very well and although you can still tell they are there, they are very comfortable with discomfort being next to none, which is a massive improvement compared to the truthear zeros especially.
Tuning,
Out of the box, the 7Hz Sonus delivers a clean but somewhat uninspiring sound. It lacks the vibrant energy found in other IEMs within its price range, and vocals, in general, come across as flat – though female vocals fare slightly better than their male counterparts. Overall, there's a dullness, a lack of life in the sound that leaves me underwhelmed.
The bass on the 7Hz Sonus plays it safe. There's mid-bass punch and a touch of sub-bass rumble for depth, but it lacks the punch some may want, It's a clean, controlled bass.
The mids are decent – natural sounding and never overpowered by the bass. Vocals come through with warmth, especially female vocals, which have a bit more presence. Instruments lack a certain weight, though, and could benefit from a bit more oomph.
Highs are smooth and controlled, definitely prioritizing a non-harsh sound over shimmer and sparkle which some like myself may not like
Techs are where this set shine truly, with these standing out in games especially, when put up against the Truthear Zeros which have been at the forefront of "Gaming" IEMs for a short period now. These are found on sale sometimes for less than £50 in which for that much, if you need a new gaming IEM. these will most definitely be a 10/10 for you.

Pros: Detail Retrieval, Soundstage, Tuning, Tight Bass, Crystal Clear highs, TonalityCons: Potentially fatiguing/sibilant, Interesting design choices, Timbre (I’m nitpicking)Intro
Disclaimer: The 7HZ Sonus was provided to us at no charge courtesy of Linsoul. However, this was done in understanding I was to give my honest thoughts and opinions of the Sonus. For more reviews like this, visit our site perrivanaudio.com
7HZ produces an interesting release in the 50-100 dollars bracket, the Sonus. It’s a 1DD+1BA hybrid, and while not the most eye-catching IEM, it claims to have a focus on detail retrieval and accurate tonality. From what I am aware, this is 7Hz’s first hybrid IEM.
Accessories
7Hz provides the usual plethora of colourful in-house silicone tips, which are not the most inspiring, but have a characteristically stiff core that suits the IEM and fits well in my ears. It comes with a sleek-looking pouch that is a really nice inclusion at this price point. The cable is also quite interesting, with a flat 4-core structure. Despite the thickness, the cable is soft and flexible, and can easily coiled. It’s also worth noting extra stick-on nozzle filters are included, which is nice if you intend to make this your daily driver.
Build Quality and Fit
The overall build of the IEM is functional and sturdy. It has a metal faceplate and a plastic shell that is shaped to sit rather nicely. It isn’t the most comfortable but it remains functional and more ergonomic than the Timeless. I’m not a fan of the overall aesthetic but I guess that’s subjective. The cable is not really up my alley but I do have friends that really liked the flat cable over the usual braided/twisted one.

Bass
Bass is sub bass focused and the beats are punchy and crisp. The midbass is tame but lacks a bit of meat so bassheads might find the weight a bit lacking in this department. However, to me, it was just fine and rather enjoyable. The decay was quite fast, keeping the basslines very clean-sounding, and yet there was satisfying rumble on the bass instruments. The present sub-bass extends well and helps to provide some body to the otherwise top-heavy sound. It is a very tasteful tuning to maintain the clarity of the sound and yet achieve a decently satisfying low end.
Mids
The mids are quite forward and present, and I love how the instruments sound on them. From violins to brass Instruments like the trumpets, to woodwinds like the saxophone. Very textured, and the details are fully captured without compromise, everything is pinpoint accurate and really mindblowing at this price point. Instrumental separation is on a whole other level. I find it hard to find another pair to compare it to within the same price bracket. In terms of technicalities, and accuracy, the Sonus has done them all so well. If I had to find a place to nitpick, it would be that the female vocal timbre is a little off on the higher notes.
Treble
The treble is no doubt sparkly and expressive. The highs are really lively and cymbals and snare hits come through with a swift attack and natural decay. This is enjoyable as it adds character to the sound and makes it more engaging. That said, I do find myself a little fatigued on longer sessions. Sibilance is very slight and only noticeable on certain tracks which are very heavy on the highs.
Overall
I really enjoyed the Sonus for instrumental tracks. It has a very fast response and surprisingly good separation at this price point. The microdetail retrieval combined with the extension of the highs gives it a certain crispiness and airiness which helps achieve a wider-than-average soundstage. If it had a slightly more polished design or aesthetic and perhaps a more comfortable shell, I am sure this would be an instant hit as the tuning and technical ability of the Sonus speaks for itself.
Conclusion
Despite its dated design and little quirks (sibilance) in the upper mids and highs, the Sonus exemplifies a neutral-ish tuning at an accessible price point done right. Its tuning is versatile for many genres and presents itself as a potential daily driver for many considering its value proposition. The bass boost helps to balance out the activity in the highs very well to put out an all-rounded performance. If what I’ve described suits the sound signature you’re looking for and your budget is right, do give the Sonus a shot. The detail retrieval and overall clarity and separation that the Sonus delivers are arguably the best I have ever seen in the sub-100 price range. 7HZ may be onto something here in this price bracket and for a first attempt at a hybrid IEM, this is pretty amazing.
