Excellent IEMs with an incredibly smooth, listen able sound.
Pros: Extremely well tuned
Incredible resolution
Easy to drive
Good range of ear tips
Well built
Cons: Poor soundstage
"Soft" no slam
The timeless is a beautiful set of headphones. Most headphones don't sound half this good, whether it be IEMs or over ears, or anything else. They will. Most likely satisfy your desires, past this point we're talking about a serious deminishing investment.

Sound
The bottom end of these is such a pleasure to listen to. It's an extremely full sub bass and mid bass region, making note weight feel full and strong.
The mids on these are very flat. It sounds neutral and is pleasing with every form of music I've tested it on. Vocals come out clear, and instrument separation is good.
The highs are not bright, the energy is there with excellent details for cymbals, for synths and any other high frequency information. They never fatigue the listener.

In regards to the tuning, there isn't much better an IEM or headphone could do. It's flat with a deep subbass, lifting almost into a v shape but not quite. I love listening to most anything on these. They're great to carry around with you. I've taken them on a backpacking trip across Europe, on tour with me across North America, and they work in every scenario. Depending on how the tips fit in your ears, they seal out most noise.

In regards to resolution, the timeless are wonderful. They have so much detail in every note. It's the best part about planar magnetics and it continues to shine here. I would say these sound better than the sundara do, and they're very similar prices. The advantage of the sundara would be their soundstage, which is fantastic. I think these are great all rounders which will please 98% of listeners.

The biggest drawback is their soundstage! Most IEMs seem like this to me, it's why I prefer headphones but especially why I like speakers best. It definitely is inside your head. The tuning really knocks it outta the park, and the resolution is great, but they lack when it comes to sound staging. I couldn't tell you where on a stage someone is standing. It's sort of three dimensional, and stereo effects do sound good still but more because of resolution than image. But in my opinion, you need to reach into the 1k ish spending range to get to that point of IEMs.

The other thing I would note is their "soft" presentation. It's hard to describe and it took me aback the first couple weeks listening. I was very used to my speakers and over ears which had a lot of "slam", so these were surprisingly gentle. But once you adjust its not really a drawback, not to me, but I can see someone who really likes a more aggressive tone not enjoying these as much. For me, two weeks in I was really appreciating the presentation. I've had them for more than a year now and they've really been a great purchase. On that point,

Value
The value of these is through the roof. I compared it to the sundara earlier for a reason. They're similar prices, but with distinct advantages for both. One is an IEM, one is circumaural headphone, but they're both planar and they're both relatively neutral. I think they're so 1:1 in fact, that I think anyone who likes the Hifiman Sundara will adore these. Amazing value for sound, and for anyone who likes the planar sound, these are such a good price that you can go outside with. It's like having a portable sundara, a brilliant neutral planar magnetic, but you can sit and listen on a plane, or with your kids around the house, or on the metro. If you ask me, that's incredible value. Past here is Diminishing returns. The other reference in this price range is the blessing 2, which I sadly have not had an opportunity to afford. To be frank, if I'm gonna upgrade, it's going to be significant. These are an amazing listen, and an incredible price.

Fit and build
My giant ear canals are fine with these. They're large, wide and circular. So just be ready for that. I like them.

In regards to the build, they feel premium. Metal casing, good cable (ugly as hell though) nice carrying case. They feel like hifi gear.

Summary
If you are in the market for excellent IEMs and you're willing to spend a bit more than something like the Aria, these are gold. This is the best tuning for price in IEMs, except maybe the blessing but I can't speak to that. I've tried many, many cans and many IEMs, and these come out on top most of the time. Go buy them. You'll probably be very happy.

Side note, I know they came out with a newer version of these with MORE Bass but I would recommend steering clear. These are so bassy sometimes that I can feel the rumble inside my brain on tracks like HUMBLE. by kendrick lamar, or 2010 by Earl Sweatshirt. I mean, the bottom is at the very peak of where it should sound good. If I were you, I'd steer away from the newer version. They're a hundred more and, though I haven't tried them, I suspect they would overwhelm with bass. These are almost overwhelmingly bassy.

Have to agree. One of the easiest IEM's to listen to over time. Just the best tuning of any IEM I've ever purchased.

I opened up Head-fi today and you know what I thought?

This sight needs another 7Hz Timeless review.


I purchased the Timeless right after hearing the Tri i3 Pro. My favourite part of the i3 Pro was the Planar sounding mids. I heard it and instantly wanted more! Bigger, Louder!!

The Timeless certainly delivers some of that. I describe the planar "sound" as if all the sounds/tones/notes in their multitudes of layers, and instruments are eminating from a singular wave. Like a plasma

I've also heard some people call it a wall of sound effect. I like mine better.


Design, Form, Cable, Tips
Contrary to some comments i've read I quite like the cable. I think it looks a little sexy, it's super sleek, has nice connectors and is all round decent quality. it also isn't too heavy which I like for convenience sake.

I also like the rotating connector.

Unpopular opinion I know..

And tips? I actually found best sound and fit with the supplied tips. (what am I? The devils advocate?) I opted for the dark blue ones purely because they looked cool. I did test Spinfits, Azla Sedna, Comply, The Nuarl Block + which I use on pretty much everything as well as some other brands but found the stocks did the job for me.

As for the IEM form. Pictures made it look a lot bigger, i was expecting something around the size of the Nuratrue Pro but was pleasently greeted by a much smaller sexy little iem.

And packaging? A delight, YES! The metal case is not the most useful, but having somehow missed on every review I read I truly wasn't expecting it and thought it added a very nice touch.


Sound

The sound of these can change quite a lot. For most my listening I was using it through my phones aux cable. Now say what you will, but I think I should be able to do this, a single driver, not too expensive, why shouldn't it work on a phone? Well the sound was thin and not particularly dynamic. It still worked on some genres, but not better than anything else and the volume? OH THE VOLUME!

WONT SOMEBODY THINK OF THE VOLUME.

The Timeless just can't get there on it's own. It gets close, but doesn't hit the sweet spot which is disappointing.

Why do I think it should be able to? Entitlement mostly, the world should work the way I want it to! But also is it unreasonable to suggest that the cheaper the iem the less demanding it should be on equipment? Do I need a Cayin Nii 9 to run a sub $300 iem? Ok, ok, a simple DAC might be fine.

Like the Dragonfly Black, which is what this review is written on.

Also worth noting is that out of a computer or laptop the Timeless is giving you a much better sound.

Actually Sound

The Timeless is a competent resolver of an iem with great separation. The bass lacks a bit of texture, but otherwise can give a non-bass head satisfying amount of bass. Sub-bass also shows itself if it's forced too. But the Timeless won't give it to a track willy-nilly


Bass - The sub-bass of the Timeless is better than the mid bass. It has rumble and impact above and beyond what you would expect from an iem with this kind of mid bass. Electronic Kickdrums dont slam or have weighty body to them but are clearly defined and have enough room to sit by themselves without touching the mids.

The sub-bass is in all ways satisfying and well contained. It's a light experience, not dark and dirty.

Mids - Vocals and instruments sit forward in the mix with what I'd call balanced. They don't quite roar at you and aren't particularly wide or exciting. Listening to it makes you realise that a lot of it's hype was simply hype. A fuller presentation might have impressed me.

Treble - High hats can come across as a little hot as the treble is forward along with the mids. It isn't distasteful but it does stop you from driving the Timeless to higher volumes to get more of those mids. . . . If you can.

Alright alright, I did plug these into my computer to get a better idea of it at high volume which is where the treble impression comes from.


Technicals -

The Timeless performs very well in the separation department keeping all layers and instruments apart. it is easy to tell what is what in the mix.

Imaging is about average with nothing really specatular or bad. It isn't the type of imaging that makes you feel like you're in front of a stage able to place where each sound is coming from and that's partly due to the soundstage. I don't really no what else there is to say about imaging, it either does that or doesn't. but not doing so isn't necessarily bad.

Soundstage
Soundstage is average or perhaps even below average. The sound isn't narrow in a sense but there is never a sense that music is coming from anywhere but the two speakers in your ears. If you compare this to the Tri i3 Pro and even a lot of TWS earphones you often have to check the connection to make sure you aren't playing tracks out of your phone instead of the IEMs.

I haven't had this sensation with the Timeless which is to it's detriment.

Planar Speed
From everything I've read about Planar and their speed I was expecting more WOW. Yes there is never a sense of 'not being able to keep up' but all that means is that the track is played faithfully without any struggle. However, as we know, struggle builds character.

Life lessons aside. I don't really get it. What does speed mean? You can't play a note faster than it's meant to be played, so what does that leave us? An accurate sound with minimal resonance. Well this daddy likes resonance. And pretty much every type of speaker can play a note as it was meant to be played. So you don't get point for also being able to do it.


Should you buy it?

It isn't a bad little IEM. But it doesn't impress me. Maybe everything else around the $300 market is trash and that's why people shat their panties over this IEM. I can't say. I do personally prefer the Tri i3 despite it being a little less clear purely due to it having some character.

The 7hz Timeless feels like the kid at school that would tell on you for not doing your homework.

Great 14.2mm planar driver Near V shape tuning with 8khz peaks.
Pros: - Fun and interesting music.
- Extended treble.
- Bass augmentation.
- Very good separation and resolution.
- Equalization can be taken well.
- A planar has excellent resolution and speed.
- A bass that sounds warm and full.
- Fit & accessories.
- Easy to drive regarding it is a planar.
Cons: - Mid bass lackness sometimes seen.
- Soundstage lacks width & slight depth.
- Imaging is kind of weak could be more precise.
- Poor microdynamics.
- 8 khz peaks.
TLDL:

If you want crisp sounding IEM with fun & don't bother about soundstage you might give it a try.
Try to get a aftermarket pure copper cable to tame 8khz treble peak & roll tips that can reduce treble & just pair it with a warm source to get the best result :D

For cable i used HAKUGEI Lucky voice Hi Fi cable which is 7N OCC copper 2core cable.
Cable is very comfortable :D due to cotton fiber shield outside .

using spinfit w1 , ZEOS Render Memory Foam Eartips , Final e seris silicone eartips
I got the best result with Spinfit w1 Eartips cause it elevated bass quantity.

[BASS]

The sub-bass is very dynamic.
The decay and attack are both fast with warm thicker tonality.
The Timeless sound clean with no audible bass bleed .
Snare hits have a dense leading edge as a result of this rising, which also thickens the bottom end.
EDM tracks benefit from the bass's deep extension and pleasant sub-bass rumbling.
This enhances the upper mids' clarity and creates a very pleasing layering effect in the sound.


[MIDS]

Electric guitars, piano, brass instruments, flute, and other instruments sound fairly well.
There is a good amount of layering and detail in the mid frequencies.
it's definitely not the most natural sounding thing I've ever heard, but overall it's a great balance.
Forward mids with good male vocal .
However sometimes it might give a harsh in female vocal & not smooth as male vocal.


[TREBLE]


Timeless may sound bright and peaky to certain people due to its peak at 2 kHz and 8 kHz.
The treble's extension is its best feature.
Triangles, hi-hats, and crash cymbals all degrade over time fast.
Upper-treble notes may still be heard shimmering,using copper cable hepls to mitigate this problem.
It has shrill sound with more ss's and tt's pronounced in the mix, but if u use any good copper cable it tames .
Being v shaped in sound, The Timeless do sound detailed and fine sounding disregarding that much bass.


Technicalities:


The Timeless are average in staging and imaging, for example.
Even though the stage height is = good, the stage width is narrow.
In contrast, imaging sector lacks to locate instruments in ordinal directions.
Microdynamics are little poor.
Speed is superb cause it is a planar driver.
pair with warm source to get the best outcome .
I wouldn't recommend to play fps competetive online game with these cause imaging is kind of compresed on these you need sharp imaging for online gaming , but for story based offline game you might give it a shot.



Rating:

Bass: 4.5/5
Mids: 4/5
Treble: 4.3/5
Imaging: 3.7/5
Staging: 3.6/5
Dynamics/Speed: 4.6/5


Conclusion :

Timeless IEMs are definitely worth the money.
They provide a natural, pleasant sound that is engaging and enjoyable despite having subpar technical performance and tone qualities.
The way 7hz has approached a planar is incredibly distinctive, and they have discovered so much brilliance in this IEM.
where the magnificent quality of the sounds it produces is so long-lasting and resolving with good copper cable with warm sources .

Might not be so timeless after all
Pros: -Soundstage is solid
-Details are solid
-Decent tuning
-Good all around
-Great fit at least for me(very flush to my ear I could lie down on these if I wanted to)
Cons: -Probably not great for the price(at least anymore)
-Although the details are good they are only a step above many of the 20$ IEMs that are out these days
-mediocre separation and imaging
-I don't like the mmcx connectors (they get kind of loose? not sure I lose sound on the left ear and have to yank it out and re-plug it)
Intro:
This will be my first review on head-fi so your feedback would be greatly appreciated! (I might use some of the wrong words but to be fair words are only here to convey meaning and that's what ill be using the words I'm using to do.)
The timeless is a very solid IEM and it will be my baseline for almost everything I review moving forward I got these alongside the moondrop Stellaris so they will be used as a comparison very commonly additionally I have many of the 20$ iems (chu, salnotes zero, wan'er, and cca cra) i have tested all the sets extensively ab testing between them and writing down my thoughts.

Presentation:

I do not think presentation matters but its always nice so here are some hastily taken pictures of my unboxing experience all without me turning my phone camera sideways so it wastes a ton of space!

After taking off the first layer there is a nice white box opening that you have the aluminum box with the magnet and you open it to see the timeless inside its a nice touch it's in the box so neatly you wonder how they actually got it in there like that I was sure that if I just closed the box it wouldn't fit anymore and it's kind of witchcraft, however, if you look at the last image you will see something weird in my pack of ear tips, one of the pairs are not actually not the same no idea how that happened but it doesn't matter because all the ear tips suck anyways not a single one fit in my ear properly to this day I use one of the ear tips that came with the Stellaris or chu's.

this is a little bit of a side tangent but honestly, if you get these and you have ears like mine I seriously recommend getting ear tips that fit I found that soundstage and imaging are heavily affected by ear tip fit I cannot stress this enough if I hadn't gotten other tips I might genuinely have been disappointed in this set instead of suddenly picking iems as a serious listening medium.

it's nice to know that they packaged it nicely for 200$ but honestly, the ear tip thing kinda threw me off.

Tuning:
there isn't much to complain about, I would say they are tuned well but I don't think they do anything really out of the ordinary unlike the Stellaris which has the kind of nasally honky 1k peak, these work fine without eq, they don't fatigue me and I don't notice anything notably out of the ordinary after multiple days of listening. i will say honestly the bass-midbass sounds a little weird to me but in general, I use very refrencey headphones like the akg k701 and the v moda m100 masters(i know the originals were v but the masters are not. funny fact is I only went onto this forum because I wanted to eq those to be less referency and got sucked into the iem rabbit hole)
ill let other people who know more do the talking for tuning in IEM's

I lack the tools to measure these and so ill post a squig graph. thanks to gizaudio and also his reviews
graph.png


Technicals:

Because I am pretty new to IEMs it's pretty difficult to tell if something is really amazing compared to other IEM's but something I have listened to a lot of are headphones mostly closed-back headphones this is where I think moving forward I will reconsider this.

At 250$ USD the v-moda m100 masters are by no means cheap headphones even though I got them roughly half off, the same is true of the akg 701k which on the akg website is 520$ USD which seems inaccurate (they are 230cad on amazon.ca although when I got them roughly 3 years ago I think they were around that price also got it on sale for roughly half maybe 60-70% price) this is also the same for the Audio-Technica ATH-M50 for 150$ all of them theoretically compete with the timeless in value this is where I have to wonder you would think that an IEM could not come close to the performance of a real big driver headphone and you would be both so right and so wrong at the same time.

Soundstage and imaging:
the timeless is so very close beating all of these devices in at least one category. (well actually not the akg 701k but I digress) first is the soundstage which I must say is much better than expected the way I measure this is kind of weird but basically I close my eyes and try to guide my hand to where I "feel" the sound, like when you wake up in the morning reaching for your phone or clock I then grab a ruler and measure this and yes this is jank and I know very unscientific but my results tend to be very consistent and is honestly better than just I feel its better or something like that. maybe someone can compare and take notes with me :).
Basically the timeless just outright beat the M50's I know the community likes to make fun of people who buy this headphone but when I got it it was my first "audiophile" quality headphone and thought it was great but compared to this it's just not even a question it beats them in details and imaging too but not surprising it is cheaper right?

if you want some exact numbers I "measured" (big air quotes) roughly 10cm of staging up and down for the timeless and 4cm to the sides compare this to the M50 which is roughly 4cm up and down and 4cm left and right, I will say the soundstage is a little muddy the edges don't sound crisp I don't even know if this is possible on closed ear much less IEM's but yeah it will never beat an open back the akg701K go longer than my arms can reach above my head.
a better comparison would be the Stellaris which loses to it a little bit 8cm up down, 2cm to the sides.
the imaging is a little fuzzy but I don't listen to much music where instrument direction really matters my go-to is listening to music by joe Hisaishi for imaging
the soundstage is something I deal with much more and ill link my little playlist that I put up its on youtube music but is missing a lot of songs I have flacs of.
https://music.youtube.com/playlist?list=PLgZ3RUX-6xkbBdiMNd1iW4MbOCF3EF0pD
YouTube music(slightly higher quality not as good as Spotify but my music doesn't always show up there)

Youtube

just as a note that these songs are just ones I think particularly show off soundstage well I mostly listen to jazz, rock, jazz fusion, mathrock and a lot of "jpop" and city pop although honestly, this is pretty non-specific I feel like What does jazz even mean anymore if everything miles Davis has produced is all jazz i don't think it means a whole lot at this point.

Details:
the details for the timeless are solid and clear I feel they just barely edge out my v-moda m100 masters it's hard to say without really going into specifics but let's just say there are certainly moments where the timeless's resolution and ability to push detail is lacking I don't know if the Stellaris is crazy or what but in many songs where there are multiple guitars with distortion the guitars almost always gets completely lost, but this completely goes over the fact that full-sized drivers are also unable to fully display the noise of the songs if I had to choose examples in the song "tower of flower" at 0:35 there is a guitar with distortion playing chords and a piano playing chords and drums and cymbals clashing in the background with prominent singing in the front on the timeless the guitars are reduced to just distortion in the right ear and you can't even hear them strum them and they are missing the notes on the keys unlike on the Stellaris but to be fair nothing else I have comes even close to the Stellaris in this one factor and i doubt most people are using them for something like this these honestly are edge cases but I really like songs like this where its just a bunch of noise a lot of vocaloid is like this for example but I would assume this is fine for most people or even "perfect" another really clear moment where this happens is in citron at 1:35 songs will be linked once again
honestly, its performance is only a little above the cca cra maybe not even by that much its definitely noticeably better than 7hz zero and tangzu waner

youtube music

youtube

neither playlist is complete but that's alright ill be adding more as time goes on and my other testing list will be linked here

youtube music

youtube

Conclusion:
This is what I assume a good IEM sounds like I think the thing that blew me away was the soundstage amazing compared to the other cheaper iems and roughly again air quotes "2cm better" in both directions than the Stellaris and "up to 8cm" more than the 20$ IEMs I would recommend these for sure but are they value? I don't think so the Stellaris as said performs greatly better in detail this comes with a massive caveat of tuning and a small dip in soundstage but most people don't exactly buy IEMs for the soundstage that being said they don't buy it for details either is it 180$ better than the 7hz zero, maybe but is the Stellaris 80$ better than the 7hz zero, absolutely. This makes me question what about the hexa what about the aria's what about the talos, etc.

yeah, I think the timeless is good in price, as in yeah that's worth 210 dollars but that doesn't mean it's good value anymore, in fact, I might have to come back to this when I get some more iem's under its price bracket.

Thank you for reading!

Review Of The 7Hz Timeless


2.jpg

Introduction


The 7Hz Timeless is a planar magnetic IEM by a Chinese company 7hz. This is their first attempt on a planar magnetic IEM which is a success as they are one of the best planar IEMs, maybe in fact the best IEM under $300. Till date there is no other IEM under $300 have better technical resolvability. Other than the 7hz Timeless they released i77, i88, i99 with their mini model as well as their recent launch 7hz Eternal. None of which I have auditioned or owned. Coming back to the Timeless, these are priced at $220-$225 at the following below:-

Disclaimer


*This is my own purchased unit, each and every thoughts below mentioned are my personal own thoughts and they are not fiddled with any outside influences.
*I do not own or have heard any other planar IEM's, so these are reviewed on their own performance.
*I will be comparing these with couple of my favorites Yume Midnight and Moondrop Blessing 2.
*I will be referring these IEMs to as 'Timeless' for the rest of the review.
*And at last I will only be reviewing the Timeless on the basis of their performance, I do not care what these are made of or packaged with when newly purchased unless it affects the sound in any sense what so ever.

Specifications


Timeless is a full planar magnetic IEM which houses a 14.2 mm planar magnetic driver which have a double sided array of N52 magnets and a 2mm ultra thin diaphragm. These have an impendence of 14.8 ohms and sensitivity of 104db. The frequency response is from 5Hz to 40kHz.

Sound


Timeless have a V-Shape sound signature, as it houses a planar magnetic IEM, the response you get from these is fast, resolved and detailed. They have great treble extension and great resolving power and at the same time being warm and natural sounding.

1.jpg

Treble


The Timeless's treble have forward treble presentation. It has shrill sound with more ss's and tt's pronounced in the mix. although being very well extended in the treble still feels soft. I find the air in the blessing 2 a little bit dry than the timeless. Also Moondrop blessing 2 have less presence in the treble than the timeless. Every element in the treble region works very well and provide better tonal performance and technicality when it comes to Moondrop blessing 2. To be honest I find the blessing 2 much better tuned. Timeless is overall better in every aspect than the female vocals while comparing to the Yume midnight. The female vocals have more natural reach when it comes to blessing 2. When it comes to a little more happening in the treble, the vocals are drowned in treble with timeless whereas blessing 2 performs eloquently and precisely which results in more details and resolution. Obviously they both are tuned very differently. Although the tonal integrity of Moondrop blessing 2 in sound is not lost overall except the dryness felt in the treble air above 8-10k region and I find the characteristics to keep it all along the spectrum wonderfully, where the timeless being v shaped in sound. The Timeless do sound detailed and fine sounding disregarding that much bass. I agree on Timeless not being clean or analytical but it doesn't want to be.

Mid Range


Like with the treble the timeless is very much forward with the mids especially the upper mids. The upper mids are shouty and really hot. Everything is so in front in your face (figuratively speaking) that the sound is intimate and close with presentation. Every element tries to take the front seat. there is really no placing or separation of instruments or vocals in the mix. There is more space for every element to breathe and play their role while listening to blessing 2 but not with timeless. The vocals sound lean and feels like at higher octaves the female vocals distort. There is a definite stage in blessing 2, there is more happening in the above and below when comparing to the timeless. Female have a more natural feel to it with Yume midnight. Whereas the lower mids feels fuller more upbringing, I find the lower octaves of female vocals in this region while listening to timeless much better than in the upper mids and treble. The overall presentation is better in all aspects in this region while listening to timeless.

Bass


When it comes to mid bass timeless sound thick and slams really hard, although being this thick sounding the lower octaves of vocals drowns due to the over bloated bass. the sense of humming on timeless have a good amount of note weight almost feels musical and natural. Very submissive bass response. comparing to the Moondrop blessing 2 and the Yume midnight the bass they produce is very controlled never takes on charge like timeless and never does feel like complete mostly in Yume midnight. The bass acting on the timeless hits fast but even though it tries to recover or decay it gets messy but maintains it's harmonic values. The Yume midnight and the Moondrop blessing 2 have a great stage for every element to breathe where as sounding musical I find it a little congested. In the bass region, when it comes to timeless the mid bass have the authoritative hand while sub bass goes with it. The sub bass extends very well but Yume have much better extension. Blessing 2 has very well and detailed bass overall.


Technical Performance


Timeless exceeds in every aspect in technical performance comparing to the Yume midnight. The Moondrops are a level up from Timeless. Timeless being a planar magnetic IEM, it has all properties of what a planar does. Being very precise have a good layering separation and soundstage and also trying to achieve a quarter in space in doing something new in bass region becoming what a planar wasn't expected to be. There is some kind of power and energy which is very unique to ears about the planar
especially when it it is coming from an IEM.

Soundstage, Sound Imaging & Separation


there is a sense of wide separation between instruments and vocals in regions where you might not find it happening. I am not saying it is the best coming to an iem in this price range, for that check out the final audio a4000 in stage department they will blow your socks off, but they are really good in staging. The layering is okayish to be honest, while comparing to the Yume midnight and the Moondrop blessing 2. The separation is quite the level of Yume midnight, not too spacious sounding nor too close. Although very easy to point out where the sound is coming from. The presentation is not entirely all around like the blessing 2. but better than the Yume midnight.

Speed & Resolution


The planar, like I said before are very fast in presentation, the details retrieval is astonishingly good. the notes hits really hard with density and decays smoothly. It doesn't precisely execute sounds the way it should but tries to keep it clean. But for the price they come in they have the best resolution under $300. Although for a planar to keep up with this profound sense of warmth and tonality while outproducing this much technical performance is marvelous.

Conclusion


Definitely Timeless are worth the price, they are engaging and fun sounding IEMs with sub par technical performance and tonal attributes which makes it sound more natural and warm. 7hz's take on a planar is really unique and they have found so much excellence with this IEM. Where it's sublime nature of producing sounds so resolving with extended length

Frequency Response​

7Hz Timeless Graph.png

This measurement has been taken with a IEC711 coupler. You can find more in my Graph Database.

About the IEM​

  • Somewhat odd design that I wouldn’t really like wearing in public because of the big disk that protrudes out of the ear
  • Excellent fit, that quite surprised me given the design
  • Great overall package with a big selection of tips and a good-feeling cable
  • Seems to have some QC problems according to other users, everything was fine with my unit
🥈Great accessory package and good fit, somewhat hindered by a unsightly design and QC problems

Sound Impressions​

  • Excellent crisp and dynamic bass
  • Treble can be piercing at some points
  • Tends to loose some detail and resolution in the treble region
  • More suitable for male than female vocals → shown quite well in “Without a Parachute by Anna Rosinelli”
  • Midbass can sometimes drown out part of the vocals and move them to the background of a track
  • Vocals can further give a “metallic” impression, especially female vocals
  • Average stage and imaging is too “central”
  • Outstanding details and resolutions, nearly unmatched at that price point
🥈Decent sounding IEM with a fun and entertaining tuning that excels with outstanding details and resolution

Song Impressions​

SongImpressions
White Dress - Lana del ReyReally hard track to get the vocals right and enjoyable. Vocals are slightly unpleasant because of the treble peaks.
Altes Fieber (ohne Strom) - Die Toten HosenVocals a tad too much in the background, live audience almost not hearable, solid live stage imitation
Another Love - Tom OdellBass suprisingly a litte lacking, Vocals get good representation and feel intimate enough, instruments tightly clustered
Exile - Taylor SwiftJustin Vernon’s vocals sound just amazing and powerful, while Taylor’s voice is just bit frayed, soundstage too close

Comparisons​

Shuoer S12: The elephant in the room​

When reviewing the 7Hz Timeless, there’s one big elephant in the room: The Shuoer S12, another well-received planar IEM with a similar tuning to the Timeless. While I haven’t yet listened to the S12, most people that have heard both, tend to prefer the S12, even if it’s just because of the about $60 lower price. When you’re looking to buying the Timeless, at least keep the existence of the S12 in mind.

SeeAudio Yume:Midnight​

The Yume:Midnight are one of the benchmark IEMs at around $200 and therefore a logical comparison to the Timeless.

Graph Timeless vs Yume Midnight.png


Advantages Timeless:
  • Better fit, especially for longer listening sessions
  • Better, more crispy bass
  • Better details and resolution
Advantages Yume:Midnight:
  • More enjoyable treble
  • Better female vocals
  • Stage is wider and imaging more exact

Moondrop Kato​

The Kato are another stable at the $200 mark and another clear contender.

Graph Timeless vs Kato.png


Advantages Timeless:
  • Better fit, especially for longer listening sessions
  • Better, more crispy bass
  • Better details and resolution
Advantages Kato:
  • More enjoyable treble
  • Better female vocals
  • Stage is wider and imaging more exact

Conclusions​

The 7Hz Timeless are quite the success. Not only are the Timeless the first Planar IEMs that are actually good and enjoyable (sorry Tin P1…), they are just good IEMs.

image.jpeg


They excel especially with technicalities that are almost unmatched at around $200. For IEMs that are as detailed and as resolving, you’d almost have to go to the about $100 more expensive Moondrop Blessing 2 (Dusk).

The mid bass is the one thing that’s a somewhat big downside for my personal preference. It tends to overpower and overshadow the mids and especially the vocals. Combined with a peaky treble performance, vocals aren’t necessarily the Timeless’ strength.

Excellent Value
Pros: 1. Amazing timbre
2. Fun bass
3. Natural vocals
4. Good resolution
5. Very comfortable on medium/large ears
6. Overall pleasant sound and instantly likeable
7. Jack of all trades
8. Easy to drive
Cons: 1. Imaging is not as good as some similarly priced competitors but competent enough
2. Detail retrieval could be better
3. Occasionally sharp lower treble (very minor issue though)
4. Bass definition and texture could use some work
5. Plasticky cable. Over the top aluminum case that's practically useless
Comfort and Build quality:
Despite its odd shape, timeless is actually extremely comfy. I can wear them effortlessly for hours without any discomfort. The cable is honestly, quite mediocre and tacky and tangles easily. Provided carry case is made entirely of Aluminum thus heavy and impractical. Also it'll often catch on my thumb skin while attempting to close the lids (very sharp edges). the earpieces themselves are well built as well.


Sound:

Timeless is probably the most perfect people pleaser IEM under 300 USD. Its comfy, has authoritative midbass heavy bass response, a well executed midrange without the wonkiness that many planars tend to have and a flawed but decent treble response. Very strong wow factor.

That being said, there are a few caveats. Imaging is not nearly as good as its similarly priced competitors (Blessing 2 and Softears Volume for example). It occasionally fails to pick up finer details from music (where Volume, B2 and er4xr excel and are at the level of IEMs costing twice/thrice as much). Layering and instrument separation are decent but not remarkable. There is an overly smooth and safe characteristic to its overall sound (with occasional rough edges in the lower treble). Timbre is excellent and handles all genres with ease (which Volume doesn't. Unforgiving to poorly mastered stuff).

TLDR: Excellent IEM. Unhateable tonality with some minor technical setbacks. I think the pricing for this IEM is just perfect.

Mini Review of the Timeless
Pros: Just a good set of IEMs overall
Cons: My personal preference leans me towards the S12 over the Timeless
IMG_20220410_150544.jpg


Intro…

I am currently on a business trip and while I am here, @antdroid (of audiodiscourse.com) has very kindly loaned me multiple sets of IEMs to try out.

First, I must apologize for the lack of photos, and the poor quality of the photo that I have included, but I am stuck in a hotel room with just a cell phone and very limited light etc.

My intention with this "Mini Review" is to share my impressions of the various IEMs after using them for approximately one day only. I usually spend at least a week with an IEM before I create a review, as I find that more time spent can sometimes make certain flaws more obvious or can also make something grow on me. Therefore, please take these "Mini Reviews" for what they are, impressions after using the IEMs for only a brief period of time.

My intention was to first post a Mini Review of the Shouer S12, a set of IEMs that has impressed me quite a bit, however, Shouer have informed me that they have sent me a set to review, which I should have by the time I get back to Spain. Therefore, I am going to wait and post a complete review of the S12, as I feel that they deserve it without doubt.

As I have already tried the S12, a lot of what I am going to mention about the Timeles is in comparison to the S12, which may not make a lot of sense due to the fact that I haven't posted a review of the S12 yet, but once I get to posting my review of the S12, this mini review will probably make a lot more sense.

Presentation…

As these are on loan, I can’t say that they include all of the packaging and contents. In fact, I know that all contents are not included as there is only one set of tips and I know that these include more, therefore I am not going to really talk about presentation.

I will say that they do include a carry/storage case that is basically a full metal box, which is a few milimeters thick and is way too heavy to use to carry these IEMs around. However, the box is quite impressive and I must give 7Hz bonus points for originality.

Build and aesthetics…

The shape of the Timeless is quite original also, definitely a break from the norm. They are a large circle shape that fits just outside the ear, with a nozzle that is quite long but makes them quite comfortable. Personally I find the S12 more comfortable but the Timeless are not bad in this regard either.

The IEMs are metal and seem to be well built, with no obvious signs of wear, although I don’t know exactly how long Antdroid has had them, nor how much he has used them.

The included cable is a bit basic but uses nice hardware and to be honest, I prefer the lightweight of it over the thicker cable included with the S12.

Sound…

In the subbass department, I find that there is less quantity than with the S12. It is not rolled off enough for me to complain but if given the choice, I would prefer to have a little more presence in this region. I found tracks like “Bury A Friend” enjoyable but would choose to add a little more subbass if possible.

In the midbass range, I must say that I find them to be very similar to the S12 and really don’t have any complaints. The low end of bass guitars and other instruments have enough presence to be enjoyable, at least to me, without being overly done and becoming too warm.

The mids are also very similar throught the lower and middle ranges, however, reaching the higher end of the mids, I find that the Timeless are not quite as forward in the vocals as the S12. I mean, the S12 are not exactly very vocal forward but the Timeless are even less so. Saying that, I cannot say that the vocals are recessed, they are not, they are still present enough for me to not complain, just that the S12 has that little bit more.

I also have no issue with the treble areas of the Timeless. The treble is not quite as smooth as on the S12, which does sometimes make it seem a little more detailed (only on specific songs). The extension and sensation of air is also good, and while it is not as smooth as the treble on the S12, it does seem to extend a little further, or at least that is the impression that it gives me.

The detail I would say is also slightly better on the Timeless in comparison to the S12, although there is very little in it. The S12 seems to be a little more smoothed over in the treble department, which does affect the sensation of detail, but I still think that the Timeless has the edge here.

Conclusion…

This has been a bit of a strange comparison to the S12, a set that I haven't reviewed yet, but to be honest, they are both excellent IEMs in my opinion. There is very little difference between them as far as sound qualities but I have found myself preferring the overall tuning of the S12. Again, it is very close and it is minor things that only really stand out when comparing them side by side, but I must say I am more of a fan of the S12.

But personal preferences aside, the Timeless are an excellent set of IEMs for their price and I would be more than happy to have them in my collection, probably getting more use than the majority of other IEMs I have.

I think that anyone buying the Timeless is making a very good purchase and will not regret doing so (if they fit their personal preference as far as tuning of course!).

As always, this is also available in Spanish both on my blog (here) and on YouTube (here)

An accomplishment
Pros: Good quality accessories
- Comfortable fit
- Excellent bass response that showcases planar-speed
- Smooth and natural lower-midrange tuning
- Very good separation and resolution
- Low-distortion driver allows for heavy equalization
Cons: - Mid-bass might lack fullness in some tracks
- Below-average isolation
- Sub-bass rumble could do with a bit more physicality (fixable via EQ)
- Upper-mids can sound grating at times
- Lower-treble ringing coupled with 8KHz emphasis
- Soundstage lacks depth
- Imaging could be more precise
- Poor microdynamics
7Hz Timeless - Cover.jpg


My first encounter with the 7Hz brand was through their i99 IEMs which had a very unique shell design that immediately caught my attention. Unfortunately, the sound quality of the i99 did not match their design prowess.

Along comes the Timeless, a pair of mid-range, planar magnetic IEMs. Given the lukewarm reception that previous 7Hz IEMs have received, one may be misled into thinking that the Timeless are another uninspired option. Fortunately, the Timeless are anything but uninspiring. Read on.

This review was originally published on Headphonesty. Linsoul was kind enough to provide the 7Hz Timeless for evaluation.

Accessories​

The supplied cable feels supple in hand and does not form kinks or bends. I am not too fond of the red and black aesthetics though. In terms of materials, it is a silver-plated and pure copper strand mixed cable and negates the need for an aftermarket replacement. The aluminium case is overkill and impractical at times but I found it to be extremely sturdy which is good.

7Hz Timeless - Cable.jpg

7Hz Timeless - Case.jpg


Design​

The Timeless have a two-piece shell design. The seam where the two pieces join can be felt with fingernails and is uneven in places. The outer shell has a coin-like shape that gives a distinct look to the IEMs. The inner-shell meanwhile, has a more traditional IEM shape.

7Hz Timeless - Nozzle.jpg


Due to the large driver size and dual magnet arrays, the Timeless are thicker than average single-driver IEMs. There are five vents on the inner faceplate: four near the channel markings and one beside the nozzle. Speaking of the nozzle, the 5mm diameter is larger than average and the mesh can be replaced if it gets clogged.

Comfort​

The 7Hz Timeless are quite comfortable and have a snug fit. I can listen to them for hours without any discomfort or pressure buildup. Isolation, unfortunately, is below average

Internals​

The Timeless are one of the few IEMs that utilizes a full-range planar driver. The 14.2mm double-sided magnet driver coupled with the ultra-thin diaphragm is similar to full-size planar headphones. However, the Timeless are surprisingly light even though they use dual magnetic arrays.

1649813846104.png


The driver cavity has an interesting design as well. It’s shaped into a half-circle and a tuning mesh behind seemingly acts as a dampener.

Sound​

The following sound impressions are formed with the stock tips (clear, yellow stem) + stock cable + Lotoo PAW 6000 or Questyle CMA-400i. Test tracks available on Tidal as a playlist.

The general sound signature of the 7Hz Timeless can be described as “bass boosted neutral”. That’s an oversimplification of course, so let’s dive deeper.

1649813936664.png


The 7Hz Timeless’ bass response is one of the best in their price class. Despite an early rise in bass shelf (starting around 500 Hz) the Timeless sound clean with no discernible bass-bleed. This rise also adds some thickness to the low-end with snare hits having a dense leading edge.

Bass here is fast with good texture. The slam isn’t as noticeable as the best planar headphones though. Also, the sub-bass rumble is rather polite and lacks physicality in stock tuning. Percussion hits lack tactility as a result.

Fortunately, the 7Hz Timeless can take EQ like a champ. If you want some extra grunt and physicality in the bass, try adding a +4dB sub-bass shelf from 150Hz downward. This noticeably improved the slam factor, though the bass then veers into bass-head territory.

1649814016283.png


Whereas the bass tuning is mostly good, the midrange is a bit of a mixed bag. First the good stuff. Male vocals sound superb. Baritone vocals have adequate heft and don’t sound hyper-clear as on some Harman curve (or its derivatives) hitters.

However, in certain tracks with high-pitched vocals the Timeless can sound grating. As a result, female vocals don’t sound as smooth or effortless as male vocals.

Perhaps the most contentious part of the Timeless’ tuning is their treble response. The lower treble is quite uneven and, to my ears, has some ringing around 5Khz. This ringing adds some odd sharpness to acoustic guitars in some tracks. As a result, the timbre sounds off, with string instruments having a metallic sheen to their tone.

1649814117561.png


The best thing about the treble is its extension. Crash cymbals, hi-hats, and triangles decay naturally. The shimmer of upper-treble notes can be heard even though they are not particularly prominent.

Staging and imaging are two aspects where the Timeless don’t stand out. The staging here is fairly narrow and lacks depth. Imaging, meanwhile, lacks the pin-point precision to localize instruments in ordinal directions.

Macrodynamics (sudden change in loudness) are portrayed well, even though with more sub-bass grunt it would be better. Microdynamics are rather poor. Subtle changes in volume are not picked up well.

Comparisons​

vs Dunu Falcon Pro​

The Falcon Pro are warmer and thicker in tone than the Timeless. As a result, the Falcon Pro are less resolving and cannot render fine details as well as the 7Hz IEMs. Bass is also noticeably slower and has some bleed in the upper-bass region.


Treble is smoother on the Falcon Pro though, so they work better for laid-back listening. Dynamics are also better on the Falcon Pro, and so is the imaging. Timeless hits back with their characteristic planar speed and superior separation. Both lack sub-bass rumble but the Falcon Pro is less textured than the Timeless in the sub-bass region.


These two IEMs have little in common and are intended for different audiences. For a smoother, laid-back, and more dynamic listen, the Falcon Pro are great. For a more technically accomplished sound, the 7Hz Timeless are the better pick.

7Hz Timeless - vs Dunu Falcon Pro.jpg


vs Audeze iSine 10​

Without the Cipher cable the iSine 10 sound horrible. They are an uncontrolled, peaky mess from analog sources and are practically unlistenable. The story changes drastically with the Cipher cable.


With the Cipher cable, the sound is V-shaped without going overboard. The Timeless meanwhile strikes a better tonal balance. Bass lacks texture on the iSine 10 compared to the Timeless, whereas lower-midrange is tuned better on the 7Hz IEMs. Female vocals and treble, however, are smoother on the iSine 10.


In terms of raw resolution these are quite close to each other but the Timeless just edges out their competition. When it comes to staging and imaging though, the iSine 10 reigns supreme. They are on a different class altogether and comparable to open-back, full-size headphones when it comes to staging prowess.


As for the non-sound criterias, the iSine 10 is impractical for outdoor use due to no isolation. They are also very heavy and I find them uncomfortable. If those caveats are manageable, and if you can find an iSine 10 in stock at all - they are the better purchase.

7Hz Timeless - Audeze iSine 10.JPG


Closing​

The 7Hz Timeless are not perfect. The treble tuning could definitely use some work, the sub-bass could do with more physicality, and the upper-mids and lower-treble need adjustment. Imaging and microdynamics are two other weak points.


That being said, the bass response is very good overall and the lower midrange is delightful. General resolution is top-notch and gives certain more expensive IEMs a run for their money. Above all, the Timeless do not require an absurdly powerful source or heavy equalization to sound good, and that alone is a great accomplishment when considering their peers.

I can recommend the 7Hz Timeless to those who do not mind a dash of brightness up top and want a taste of planar in IEM form.

7HZ TIMELESS - THE MUSICAL PLANAR

7Hz
was founded in 2018 and is a relatively new audio company. 7hz Stands for 'Theta' wave, a frequency associated with harmony and meditation. With their first planar they made quite a wave in the industry and hence we are gonna take a dip into it today to see if it really there in mediation with the music or not, so here comes - 7HZ TIMELESS.

DISCLAIMER:

This unit has been provided to me from Theaudiostore.in for review. This review is completely based on my experience with it and all opinions positive or negative are my own and no one else’s (no one can have my thoughts 🤣). Please try it yourself if you can, since we all hear things differently. The link for the iem is here.

SPECIFICATIONS-
Driver: 14.2mm planar driver
Impedance: 14.8ohm
Sound pressure level: 104dB/1Khz
Frequency response range: 5-40000hz
THD: <0.2%/1KHZ
Connector: MMCX 😑
Nozzle diameter: 5mm

PRICE-
17990 INR OR 219$

UNBOXING-

Unboxing is pretty good like other chifi manufacturers. But the most different thing is the inclusion of that beautiful silver heavy metal case inside which were the iems and cable. Rest is pics 😁

timeless (1 of 8).jpg
timeless (2 of 8).jpg


BUILD AND FIT-
The iems are built pretty nicely. They have a matte black shiny finish with their names on it with a beautiful silver color. They are rounded to accommodate the planar inside but the nozzle is small in size and has a good length, so fits inside the ears pretty easily. Fit is not an issue with me except it doesn't go that deep but good thing it's deep enough for me.

timeless (3 of 8).jpg


CABLE-
The cable is decent. There is no micro phonics, it's supple and doesn't tangle that easily. Mine came with 3.5 😑 but 4.4 balanced connection is available. The cable is mmcx so I am a bit skeptical about the durability.

timeless (5 of 8).jpg


ACCESSORIES-
  1. Aluminum case😍
  2. Wide assortment of silicone tips in good cases 😁
  3. MMCX cable 😑
  4. Documents and QC card
timeless (4 of 8).jpg


NOTE- This IEM is used with-
  • N6ii and R01 (mostly R01 since it adds more naturalism to the iem and also better stage) for portable on chair listening experience for the most part of the review. About 20-36 volume on Low gain
  • The T01 module has better pairing overall, expands the stage, adds more details and the treble peaks are more controlled.
  • On desktop- N6ii LO and A30s (Burson V5i D) and XDUOO MT602 Sylvania tubes ( beautiful pairing but then low gain on N6ii and also volume at 05 😁) have been used.
  • Sometimes LG G8x as a phone source.
  • Tips used were stock ‘M’ sized stock tips, this was a great fit but used red stem tips which were a great choice for me and had no sibilance
SOUND IMPRESSIONS- THIS IS SUBJECTIVE AND YOUR OPINIONS MAY VARY FROM MINE

SUB-BASS-


The sub-bass is very dynamic. The energy is a bit lacking but the rumble is more dependent on volume, something that isn't new to me with planars. Using an amp even though it's sufficiently easy to drive, makes the rumble very much soulful, while keeping the other sounds in check from getting too loud. There is some texture too. The decay and attack are both fast with a kinda slightly thicker tonality. Inter-notes separation is good even with the thick notes😁 Notes have a good body and beginning definition but edge definition is not that pronounced. Timbre is also fast hence projection of notes and reverb is less.

BASS-
Bass isn't lacking much behind sub-bass. The notes are equally dynamic but with greater energy and kinda soft. Addition of an amp, tightens the bass further but as such the difference is minimal. The mid-bass body is small and controlled but with good extension. Tonality is slightly natural here and accurate to the percussion instruments 🤩. Notes are well separated from each other due to fast decay and fast attack. Timbre is slightly presented but texture is more prominent overall. Notes edge definition needs more prominence along with extension of the notes.

timeless (7 of 8).jpg


MIDS-

Vocals-
They are very smooth. Male vocalists and female vocalists have bigger bodied notes. They have no air in them though. The extension is less but the lushier tonality makes you forget to check anything else 😅. The reverb is less but the small details like Lip smacks etc does come through easily. There's no hint of 'sss' even if the vocalists try 🤣. It's very smooth and lush for a very musical experience not much tuned for technicalities it seems. The voices differentiation is pretty good and makes it very smooth sailing in vocalists heavy track.​
Instruments-
Instruments in the mids are lively. They have a lot of energy and are dynamic. Notes reach very good height and the height difference alone makes them quite enjoyable. Tonal accuracy is great but the thicker tonality is no go in congested tracks when the stage is already this small. Notes decay and attack is fast giving very good inter notes separation but timbre lacks hence the projection is not much. Even with the above , the inter instrumental separation is great but on very close layers, which are close enough to make them feel congested. But the notes definition and beginning are not taken down at all and they shine through everything. Note edge definition is not present though and they feel blunted at the edges. Microdetails are beautifully placed and comes through subtly. Overall, a musical experience in its entirety, great for a working listening session.​

timeless (6 of 8).jpg


TREBLE-
Treble is very smooth but has great energy. It's not extended well in the treble region. Certain instruments like cymbals, hi-hats and other metallic instruments have a full bodied feel, while air instruments like trumpets, saxophone etc have a very thin bodied feel. Electric guitars are great except in the extension of notes. Edge definition is missing in the notes , but the notes beginning is greatly defined. Tonal accuracy is good with slightly thicker notes. Dynamics are great with a beautiful fast attack and decay which just separates the notes pretty great. Inter-instrumental separation is much better here than the mids. Timbre is slightly present with microdetails being very transparent but premiered in a musical way entirely.

HEADSTAGE AND IMAGING-
Headstage is lacking a bit. Only good thing is it's height. The depth(-y axis) is okayish but width is very small and stage depth is literally very very less. Only the small closed layers are felt sometimes. Imaging is entirely diffuse but the direction of the instruments are much better with instruments in the front rather presented on top.

SEPARATION AND RESOLUTION-
The beautiful thing about planars is their layering and separation, which thus iem has nailed in one while dismissing the other entirely. Inter-notes separation is pretty good but there is very less inter-instrumental spacing and separation. The tonally accurate notes rather help much better and hence makes them feel musical rather than being felt as congested. Resolution is average but whatever's present is musically shown with a little less transparency.

Intro

P1011111-1024x576.jpg
Disclaimer: The 7Hz Timeless was purchased with my own money for my personal use and this review is written of my own accord. All opinions here are my own. For more reviews like this, do consider dropping by our website.

I’m incredibly late to reviewing this pair but I really took my time with this one. Spoiler alert: I enjoyed my time with the 7Hz Timeless, but I just wanted to make sure I wasn't carried away by the hype train.

Accessories

P1011144-1024x576.jpg
The Timeless comes with quite a selection of silicon tips and some foam tips. Honestly, they didn't really appeal to me so I tip rolled a few third-party tips and after trying on the Azla SednaEarfit Tips, I never looked back. An extra set of nozzle filters are also included.

The bundled case has a full metal construction with a fabric lining on the inside, it’s a little small considering the Timeless is on the larger side and I didn’t really like the idea of the metal construction as it’s really heavy and can scratch other things in your bag.

The stock MMCX cable can come in the termination of your choice (2.5mm/4.4mm balanced or 3.5mm single-ended).

Build Quality and Fit

P1011136-1024x576.jpg
To get the build quality out of the way, I think they are handsomely built, with all-metal construction for the buds and a matte black finish. My only concern is the MMCX connection as usual, but I don’t think you would have any issues as long as you connect/disconnect them properly.

However, the fit is a little out of the ordinary. There is a huge circular disk acting as a faceplate, giving the IEM an iconic look. It’s good to note that the disk is only on the exterior and doesn’t touch the ear, hence I didn’t have any discomfort, though YMMV. The nozzle isn’t too long, but the stiffer and slightly longer nozzle on the AZLA SednaEarfit tips helped give a tight seal.

Bass
My biggest gripe with the 7Hz Timeless is probably the bass. The bass seems a little mismatched with the rest of the sound in terms of speed. The bass comes off a tad bit too strong and heavy-footed, especially when I first tried it on. It slowly became more enjoyable the more I listened to it (brain burn-in?) Perhaps it provides a slight relief and respite to the crystal-clear attack of the upper mids and treble, making the 7Hz a much more enjoyable Planar IEM as compared to others like the TinHiFi P1.

The bass extends very deep and has a satisfying sub-bass rumble that shines on EDM tracks. This plays well with the clarity of the upper mids and gives a very nice layering effect on the sound.

Mids
The upper mids have a very crisp response. The tonality of the mids are very impressive, and the Timeless strikes a good middle ground between resolution and musicality. Exceptional performance for its price bracket. Vocals shine well with a soft edge to them so they don’t come across as overly clinical. Plugging the Timeless into a better source makes the mids a bit more expansive and gives it more space to shine, overcoming the "recessed" feeling. Timbre is also very pleasant.

Treble
Treble is very speedy and have a very good resolution. Cymbal crashes come across a little dry without any splash, but with a very sharp attack, and I can see why some people may not be a fan of this characteristic. However, I appreciated how it made the percussions punchier and crisper, and I really enjoy the nuance and layers that it adds to the sound. The Timeless can handle complicated and congested music with ease. However, on some songs, it can get a little too spicy, and potentially fatiguing for long listening sessions.

Overall
I used the 7Hz Timeless predominantly balanced on my desktop setup as I didn’t really fancy it as a portable pair. I found my setup gave it a very nice breadth and height, and it performed well enough in terms of staging for an IEM. The sound signature is rather balanced with a boost of warmth in the bass. However, it isn't anything over the top to send this into basshead category.

I won't attempt to do a full comparison to the TinHiFi P1 since it has been a while, but one thing I can say for sure is that the tuning on the Timeless is much more palatable and less fatiguing than the P1.

Conclusion

P1011108-1024x576.jpg
The Timeless performs excellently and fulfils its niche as a planar IEM extremely well. It plays to its strengths perfectly. That said, the Timeless still has its “flaws” or certain caveats that not everyone would be a fan of, like the fit, and tuning, which at the end of the day, is a personal preference. From my perspective, the Timeless suits my tastes and library very well and I absolutely don’t regret a single cent I spent on it.

The Timeless managed to deliver a stellar resolution with a pleasant tuning, earning its place in my personal collection. Is there room for improvement for future planar IEMs? Yes but I foresee the Timeless sticking around for quite some time.

I'm curious what you mean by "compressed sound overall".

@visor I mean that it lacks note depth, every note sounds as if It is squished up against a surface. The lowest and most subtle sounds are not appropriately low and subtle, but raised in volume.

Good, but not perfect.
Pros: Good price for a planar-magnetic headset; nice bass; comfortable mids; good resolution; good design.
Cons: Unsmooth treble; uncontrolled distortion in treble.
It's been a while since I got the Timeless, but I haven't reviewed it.
Until today, I use a desktop amp to drive it and finally find its charm, so I decided to write a review.
1641480363556.jpg


Before that, I used my phone to drive it, because of seeing its parameters: impedance: 14.8 ohms, sensitivity: 104db, I thought it was a headset that can be easily driven by mobile phones, but the sound I got was not as good as expected. But today, I plugged it into the K5Pro ESS, and the sound performance of Timeless has therefore made a qualitative leap.
uri_mh1641543766899.jpg
uri_mh1641543662495.jpg


Appearance and Wear: The appearance of Timeless is a bit like a vinyl record, especially the CD texture on the back panel. The shell is made of aluminum alloy and the weight is very light. When I first saw its round appearance, I thought it would be very unfriendly to wear, but in actual experience, it is even more comfortable than many headsets due to its light weight and excellent design.
1641480363547.jpg


Sound: As mentioned above, when the Timeless is driven by a mobile or under insufficient power, the sound performance is not ideal and will be a little dry, but when it is driven by a higher power desktop amp, the overall sound has been greatly improved. The following descriptions of sound are based on when the Timeless is driven by the K5PRO ESS.
uri_mh1641543869258.jpg


Bass: The amount of bass is very moderate and will not overwhelm the midrange or affect the treble. And it may be because the Timeless has adopted a planar-magnetic driver, Its bass texture is not like the dynamic driver or balanced armature. It has the atmosphere what the DD can provide and the sense of speed what the BA can provide.
1641570310857.png


Mids: Timeless's handling of midrange is like a model. There is an falloff at around 600Hz. This falloff can not only reduce the “blur/fat” of the midrange and increase the overall sound transparency, but it will not let us feel the lack of midrange or the thinness of the sound. But for me, the sound of 2kHz is a little bit too much, which would highlight the vocals.
This is the equalizer I adjusted for the Timeless on Foobar2000.
screenshot-20220107-143724.png


Highs: Very standard, sehr gut. The treble resolution is even as good as the Variations(Moondrop) which adopted EST drivers for the treble. Because there's a reasonable falloff at 6kHz, the Timeless will not produce too much sibilance. But the curve of the treble part is not very smooth, which means its distortion control is not very good, so is its sound. I hope the next product from the 7Hz can be improved.
timeless.png
1641608150562.png


Conclusions: On the premise of having a device that can provide enough power for it, this headset must be recommended for purchase. But the problem of unsmooth treble, I’m not sure whether this is a probability problem or a common problem, because I have seen Crin's graph which shows a similar phenomena. It will be worth looking forward to if this problem can be solved in future versions/products.

Phones can't be used as DAC/AMP to measure headsets graph, and you can't see the bass texture, bass dynamics(bass control), sound stage (it's like crosstalk) and so on from the FR graph. Graph is not a panacea.

ok then what about comparing a cheapo dac like the infamous $10 apple dongle graphed against a more powerfull amp ?

I think my phone(vivo Xplay5s), which got dac*2+amp*3, is more powerful and better than the apple dongle. But even so, it only gets the Timeless to a "able to have sound" level. Better to use a dac/amp dongles at least.

A strictly casual listen for the closet bassheads!
Pros: Decent treble extension
- Nicely done sub-bass
- Upper mids are nice and snappy
- Decent stereo stage width
Cons: Bass is more quantity over quality
- Mid-bass hits quite soft and feels impactless
- Strictly average separation and soundstage depth
- Lower mids make male voices on certain tracks lack soul
I purchased the 7Hertz Timeless from AliExpress; no reviewers discount. The primary reason why I went for the Timeless is to look for a mid-tier offering that could help replace my Moondrop Dusk. I love the Dusk but the lack of treble extension is quite apparent on certain tracks which I listen often (The Thieaudio Clairvoyance is the reason why it is quite apparent to me). So, I though that the Timeless should fix this issue and I can manage with a slight V-tuning; probably even potentially replace the Dusk.
IMG20211130151430.jpg

Let's get on how the story unfolded. I am not going to discuss much about packaging as almost every other review covers this part a lot. So I'll just say that, yes, the packaging and accessories are top notch for the price.
IMG20211124191227.jpg

The stock cable is one of the best I have seen, irrespective of price range.
IMG20211130151518.jpg

Tip selection & fit:
One of the most important aspect of every IEM experience is the tip selection. The default tips that came on the IEMs are pretty good and offer great seal, but not the best for these IEMs though. The pressure from bass is quite high. Replacing them with the stock dark blue helps relieve some of the pressure. Sony EP-EX11M offer a better tonal balance, while a short stem, wide bore silicon tip is the best in my opinion.

The Timeless is an odd shaped IEM. While fit was fine for my large ears, comfort on longer sessions were strictly average - the Antitragus of the ear gets uncomfortable after a while.
IMG20211130151454.jpg

Sound analysis:
The first thing that I noticed with the 7Hertz Timeless is the bass - the sheer quantity of it. While I like sub-bass and a decent amount of mid-bass (Dusk, Clairvoyance), the Timeless I feel overdoes it. You can make do some of that with the right eartips for a better balance. Your brain can adjust to the additional mid-bass offered by Timeless.

However, the problem is not with the quantity, but the quality of the bass - there is a decent level of texture in bass notes, but they are too blunt, offering no impact. One of my favorite albums Thiruda Thiruda by A.R. Rahman has two amazing tracks, where bass impact defines the enjoyment of the track - Konjam Nilavu and Thee Thee. The Timeless sounds limp and there is no enjoyment on these tracks. Switching to Dusk immediately shows the difference a better bass driver can offer (though the Dusk itself doesn't have the tighest bass).

The other issue I had was the lower mids are slightly recessed. So, on tracks like Hotel California (Hell freezes over), the vocals don't excite and sound more heady.

The staging on the other hand is mixed - the width is decent, but the depth is stictly below average. I wasn't able to appreciate layering in music. The bass pressure further congests the stage to a noticeable extent and separation suffers. So I can recommend Timeless strictly for casual listening only.

Now that we have got all the negatives out of the way, lets focus more on the positive.

Sub-bass is done well and it is quite enjoyable - the texture is decent and the IEMs offer the rumble, where needed. Upper mids and treble extension are excellent. While I missed the airiness in some songs on the Dusk, Timeless was able to handle them much better than the Dusk. The treble itself, on the Timeless, can sound a bit artificial at times, but that is something that I did not notice often.

For a $200 IEM, the Timeless does a lot of things right, but for a $100 more, I would say that the Dusk is a much better option and that is what I decided to keep. To me, my entry level ER2XR is a better offering than the Timeless when it comes to the sound quality. So, I did sell the Timeless at the same price I got them for in 4 days, as I don't see myself going to them a lot (and I am not a hoarder :))

The Moondrop Kato is another competitive offering in the same price range as the Timeless and, from what I have heard from others, Kato is a better, well-rounded offering. While I wouldn't be going for the Kato (nothing new from the entry level offerings I have), it is something that you should consider before going for the Timeless.

Conclusion:
Timeless maybe the best tuned planar IEM, but as an IEM that I use to enjoy my music, they are not something that I would personally recommend. While there are likeable bits to the Timeless' sound signature, the ensemble doesn't excite. I wish that the next iteration can bring forth a well-rounded IEM.

Review setup:
Portable setup: Android Phone with UAPP > E1DA 9038S/9038D
Desktop setup: Galaxy Tab S7 with UAPP > Topping D50s > iFi iTube buffer > Headamp GL2

Timeless needs more current than what a regular mobile 3.5mm Jack can offer, but they don't need a desktop amp. A decent portable dongle should be sufficient.

@shameer - I don't have the BL03. But if you want a budget offering that's better than the Timeless, you can get an ER2XR for $60-$70 during sale. With a double flange tip, they sound excellent.

Trick is to use a tip, a size smaller than what you would for a shallow fit IEM, to get better isolation and comfort while getting the best of the bass boosted DF tuning.

Thanks for the suggestion., Er2xr for 60,70$??!!! Where it's possible

What about moondrop Kato ..how can it be compared with Timeless
W
War Penguin
The blon is an amazing iem at it's price in terms of technicalities the Timeless sounds better in every way, faster more extended bass, much better resolution and wider and deeper soundstage. But the blon BL03 are still less offensive and sound good on almost any track with a very sweet midrange, for some tracks the BL03 still wins on vocals alone when compared with timeless.

Introduction​

There's a lot of variety when it comes to driver types in the IEM world, from dynamic drivers, BAs, ESTs, to piezo-electric tweeters. And of course planars. Planars are a staple in the headphone world, with headphones from manufacturers like Audeze and HiFiMAN reflecting as some of the best headphones the world has to offer. But when it comes to IEMs, the story is a bit different. And not in a good way. Suffice it to say that I have not been a fan of a single planar IEM that I have heard. At least in the case of technical marvels such as Audeze’s LCD-i4, the bottleneck seems to be tonal balance. This is where the Timeless comes in, having been touted by the community as being something of a tuning marvel amongst planar IEMs and at a mere $220 no less. Read on to find out how the Timeless stacks up to my ears.

This unit was provided for review courtesy of Linsoul from which you can buy the Timeless here. Thank you! As always, what follows are my honest thoughts and opinions to the best of my ability.

Source & Drivability​

All critical listening was done off of my iBasso DX300 and iPhone 13 Mini with lossless files. The stock cable and stock ear tips were used. The Timeless takes a moderate amount of power to drive, but no more than would be required of most single-DD IEMs. I found myself at ~ 30% volume on my iPhone to hit my usual listening levels of ~70dB.

The Tangibles​

The Timeless arrives in a fairly small box with the following accessories inside:
  • Aluminum case
  • wide assortment of silicone tips
  • MMCX cable
  • Documents and QC card
7Hz Timeless Review | Headphones.com


I don’t like the case that comes with the Timeless. It’s milled out of solid aluminum with a magnetic latch, but something about it feels “off” to me. Maybe it’s the dried glue I can see leaking out from the felt lining inside. Maybe it was the grime smeared on the top of the case when it arrived, maybe it’s the chemical smell, maybe it’s the inconsistent machining. In all fairness, I don’t really expect good cases with a product like this, but this case could use some work.

7Hz Timeless Review | Headphones.com


The Timeless itself has a circular, aluminum shell mated to a plastic frame. Despite the quality-control memes I've read about on some forums, I don't think this is a particularly poorly built IEM and close examination of the build didn't point out any issues. If you’re concerned about the fit of the Timeless, go grab a nickel and stick it in your ear - there's your fit test. Surprisingly, the Timeless actually sits pretty nicely - almost flush - in my ears. However, I found comfort to be more of a mixed bag, as I could feel the circular shells starting to dig in after a couple hours. As usual though, fit is 100% subjective and your mileage might vary!

7Hz Timeless Review | Headphones.com


The cable of the Timeless is pretty nice in my opinion - at least as far as usability is concerned. It's fairly pliable, doesn't kink, and locks into place solidly via the MMCX connectors. There's even some slightly more complex machining that's gone into the 'vents' on the hardware. You won't see any complaints from me on this front.

Sound Analysis​

The frequency response below was taken off of an IEC-711 coupler. There is a resonance peak at 8kHz, as such, measurements after this point should not be considered entirely accurate. You can visit this link to compare the Timeless to other IEMs that I have graphed.

7Hz Timeless Review


Here, the Timeless certainly makes its mark for actually being listenable straight out of the box (unlike most all other planar IEMs I've heard). But let there be no mistake: listenable tonality is no substitute for good tonality. To my ears, the tuning of the Timeless is simply chock full of minor issues, namely 1) the bass shelf, 2) the amplitude of the pinna compensation, and 3) an unbalanced treble response. Collectively, they result in a presentation that impresses on first listen, but that slowly rings some alarm bells for me over more extended, critical listening.

Again, I have to admit that I was impressed when I first heard the bass on the Timeless. It strikes a good balance between sub-bass and mid-bass; while perhaps some might desire less mid-bass quantity, I tend to enjoy a “fuller” sound to my bass anyways. But closer listening has me feeling less satisfied. The slam of the Timeless is fairly pillowy in tandem with what some might deem the characteristically “soft” planar transients; I’ve heard BA IEMs (albeit more expensive ones) that slam harder. Similarly, I don’t think nuance on more complex genres such as drum n’ bass is as good as it could be, especially given planar magnetic transducers are generally praised for their low-end distinction. Overall, the Timeless has satisfying bass on the surface, but comes up shorter when I listen more closely.

Now let's address the pinna compensation of the Timeless. For readers not familiar with this term, this is the region from 1-3kHz that should exhibit a steady rise to account for IEMs bypassing the ear’s natural resonance peak. While the Timeless does exhibit good amounts of bass presence to “balance” out some of the rise to its pinna compensation, I find that the upper-midrange of the Timeless is quite forward, almost annoyingly so at times. It teeters on what some might deem “shouty” - equally sounding like some vocalists are on the edge of sibilance - but never quite actually delving into it because of the subsequent slope off of 3kHz. The contrast to the thicker, slightly recessed lower-midrange makes this come across as all the more perplexing to my ears. If 7Hz had chosen to either 1) focus more energy away from the lower-midrange, or 2) mitigate the degree of pinna compensation, then I think this would have resulted in either a cleaner or a more natural sound respectively. Alas, as is, it just sounds slightly off to me.

Of course, these are more minor gripes with the Timeless. What’s definitely in need of work is the treble response. The Timeless is lacking some energy at what sounds like 5-6kHz with percussive hits coming across noticeably more defined, heavy, on its competitor the Moondrop Kato in A/B comparison. This perception of the Timeless’ treble is likely exacerbated by a subsequent peak at roughly 7-8kHz. Most all IEM will exhibit a peak here in measurements due to coupler resonance, but the one on the Timeless does seem to be a few decibels higher than I’d like, thus lending to a slightly “spicy” treble presentation. I found this to be especially apparent using any tips that were not the stock ones; the treble and the upper-midrange of the Timeless sounded sharp and unbalanced. It’s a shame given that outside of this, the Timeless actually has excellent treble extension - some of the best I’ve heard for $220.

timeless4.jpg

Technical Performance​

In a similar vein, I feel comfortable asserting that the Timeless is a stellar technical performer for $220. This is most apparent when it comes to traditional metrics of resolving capability. While transients on the Timeless are articulated with what I’d describe as a “brushed” quality to them, they are quick and lend the Timeless to clarity that belies its price point. The speed of the Timeless’ presentation is readily apparent on a track like Aimer’s “i-mage <in/AR>” wherein there is a strong sense of distinction between the rapid, individual plucks of the strings from the side channels and when the drums eventually enter in the center channel. It definitely has its competitor the Moondrop Kato beat here in A/B. However, something left more to personal interpretation would be the characteristic “planar timbre”. The Timeless leans drier in its presentation - some might say more compressed - and this is especially true when it comes to its treble response.

The Timeless also stumbles when it comes to its imaging performance. I’d say it’s somewhere within the realm of average, perhaps slightly below average if I’m being more harsh. It’s worth noting that I’ve seen a wide spectrum of impressions on various forums about the imaging performance of the Timeless, some attributing it to differences in frequency response (ie. poor quality control). That said, I have heard two units (of which mine measures as one of the best I’ve seen) and A/B with similarly priced contenders such as the Tanchjim Hana 2021, the Moondrop Kato, and the Dunu Falcon Pro presents a noticeable gap in the imaging department. On Sawano Hiroyuki’s “A/Z”, for example, the opening electronic beeps are relegated almost solely to the left-right channels and they sound squeezed together. Again - the Timeless is definitely fast and detailed. But it's hard to knock the feeling that its localization ability (outside of the usual left, right, center) and its soundstage ambiance in general are somewhat subpar.

Assessment of Value​

The Timeless joins a pack of new ~$200 IEMs that have hit the market, each of these IEMs having won praise for a relatively strong price to performance ratio:
  • DUNU Falcon Pro
  • Moondrop Kato
  • Tanchjim Hana 2021
7Hz Timeless Review | Headphones.com


I think it’s safe to say that the Timeless at least competes with these IEMs. Perhaps not in terms of tuning - especially it comes to versus the Moondrop Kato and the Tanchjim Hana 2021 - but it definitely has a small technical edge over all three IEMs. The Timeless, then, is the IEM to buy if you’re indexing more heavily for an upfront, high-clarity sound. On the other hand, the Falcon Pro might be considered the antithesis of the Timeless. It has a considerably less clean presentation, yet its treble, imaging chops and timbre run laps around the Timeless for listeners who are after a more laidback, natural sound.

The Bottom Line​

In my opinion, the 7Hz Timeless certainly merits some of the praise it's received. It’s probably the best planar IEM as a whole that I’ve heard to date (if you ignore DSP in the case of Audeze’s IEMs). You could even say it’s shifted the paradigm of the planar landscape and what we, as consumers, should expect from planar IEMs in the future. That in mind, I would give the Timeless a solid recommendation if you’re after the planar sound and the technical advantage it brings. But I also don’t think I'm entirely aboard the hype train. In the context of the broader market, it’s my opinion that there are IEMs such as the Tanchjim Hana 2021 and the Moondrop Kato that edge out the Timeless as a total package. An even better question might be whether the Timeless can “stand the test of time” as its name implies, especially considering I’ve already listened to another planar IEM with a near-identical frequency response to the Timeless. Perhaps the Timeless is just the spark for what we can expect in the future from this neglected (or rather, poorly implemented) IEM driver type.

Honestly I think 7Hz would do themselves a huge favor by re-evaluating the cable and tip selection in the kit and then reissuing the kit as a "Pro" version. For $30 retail, I have upgraded my Timeless with a cable that blows the stock cable out of the water. The Timeless REALLY responds well to better quality cables. Similarly, Spinfit tips really bring out additional clarity and separation compared to the stock tips. Many other manufacturers are including Spinfit tips in their stock kits, and for good reason.

With minor upgrades, the kit might cost maybe $250, but easily beats IEMs at more than twice that price.

Completely agreed on the treble response. The tonality sounds quite off in the highs, with hi-hats and cymbals sounding rather tizzy at times.

I found that you can indeed make the Timeless bass slam but it requires a further sub-bass boost (I tried adding 3dB shelf from 150Hz down via PEQ). You can give it a try. Didn't seem to bleed too much into the mids and enhanced the rumble noticeably.

Awesome review as per usual. I agree with most of what was said. At the same time I slightly prefer the Tmeless to the Hana. I think we have been spoilt in this price range. The standard is very high. The fact all the goldilocks iems you mentioned are all very decent single driver iems. Once again a great review from someone who knows what they are talking about.

Notes are sharp, crossing the threshold of comfort sometimes
Introduction:
When 7Hz released the Timeless, their 1st closed back planar magnetic iem - the buzz was quite substantial, especially because of the $220 Price tag. To be honest, I was skeptical, as their previous single DD offerings have mostly mixed reviews - some loved, some hated them. In a similar fashion, Timeless also got its fair share of rebuff. I never had the confidence in them to actually go for it, but when my friend offered it to me for an audition, I accepted without a second thought.

In The Box:
The first item that pops out is not the iem, but the solid aluminium chunk of a box. It is shiny, it is heavy, and it assures protection like no other. Honestly, the box alone should cost a premium.
The double sheared silver coloured cable, constructed of an inner core of single crystal copper and silver-plated single crystal copper and an outer layer of silver foil, looks stunning to say the least. The cable has some weight but not uncomfortable.
There are several pairs of eartips, and I liked the black coloured cylindrical tips - they gave the best fit.

Build and Fit:
The black aluminum shell is well built - did not feel poorly made. Although there has been news of the shell splitting open, I did not encounter any such issues.
I had a doubt given the odd shape of the shell whether these will fit me. But surprisingly, in spite of the large circular faceplate, the fit was super comfortable for me - the faceplate did not prove to be an inconvenience.
However, I do have reservations against the circular faceplate, since a noticeable portion of it is just for the sake of completing the circle. I would rather have the shape of the faceplate altered to match the shape of the shell and pick a different design than the concentric circles they decided to go with.

Sound:
Timeless has a U shaped distinctly fun sound signature - an elevated deep full bodied bass, slightly recessed but largely evenly placed midrange, and boosted high frequencies full of energy and sparkles...which sometimes might be a bit too much. Bass boosted bright sound is how I would define them. But anyway, let us go into the details:

Low:
I must say, I was not expecting such a deep low end from it. So I was quite pleasantly surprised to say the least. The bass goes deep and has a considerable emphasis. Juicy and full bodied with enough texture - this is how I would describe the low end. However, in spite of the abundance of emphasis on the low end, the marvel lies in the fact that it absolutely does not obscure the rest of the spectrum, which, although, has been a pretty regular feature in the recent iems with at least decent competence.
Low end notes have a substantial presence with enough weight and body - they never feel lacking. Bass drums sound appropriately powerful, cello notes have that expected depth. Subbass is not lacking either. However, the impacts have a hint of softness, but it does not turn down the enjoyment factor.
Subbass has a hefty presence with a natural decay that enhances the reverberation. Midbass slams with a great body and yet does not get in your face, while reproducing the textures rather well. The kickdrums in Metallica - The Four Horsemen are reproduced effortlessly.
With a dynamic full-bodied yet controlled bass, Timeless delivers plenty of satisfaction to the listener without doubt.

Mid:
The mid frequency is pushed back, no doubt. However, they are not pushed back into oblivion, just enough to create a nice sense of space. Moreover, the mids sound to be spreaded in an even way, vocals are not favoured over instruments and vice-versa.
Timeless produces a transparent and very crisp midrange. There is plenty of air and a very good degree of separation present here. Tonality is definitely on the brighter side. However, the emphasised low end saves the male vocals from getting too metallic and thin sounding by adding some weight. When Leonard Cohen starts singing Hallelujah, his voice starts deep, but when it reaches higher, a slight roughness comes which gets accentuated on Timeless, making it a bit more edgy.
The female vocals, on the contrary, have splendid energy, and, even though they do not sound thin, they do occasionally hint at sibilance! Yao Si Ting’s voice in Scarborough Fair has an evident sizzle that in some instances might cross the threshold of comfort. However, on all the occasions it does not, her voice sounds ethereal.
The midrange notes have a distinct sharpness that enhances the perceived details and separation noticeably, but also might introduce a hint of metallic sheen. Electric guitars belt out pretty aggressively when called for, acoustic guitar notes are bright and sparkling clear - sometimes a bit too clear for its own good. Snare drums sound very crisp and well reproduced. Overall the notes are quite detailed and cleanly reproduced.

High:
Following the mids, the high frequencies have a similarly bright and airy signature that feels perfectly in line with the rest of the spectrum. Treble has plenty of energy, notes are crisp and edges are fine, although that in some points might prove to be a bit too sharp. Extension of the upper treble is quite good as well.
Both lower treble and upper treble have an almost equivalent amount of energy, wherein the bright cymbal crashes are followed by a suitable amount of shimmer.
In a complex passage, like Eluveitie - Inis Mona, it’s the high frequencies that grabs the attention invariably. Granted, the track sounds quite airy and open, but the way treble becomes the focus of the song becomes a bit uncomfortable for me.
Coupled with that, because of the Planar magnetic driver nature I guess, the treble has a distinct metallic sheen that makes the cymbal and hi-hats sound extra spicy. This may prove to be a point of concern in the long run. I must say, there was no sibilance, though. Just the brightness and tonality was not for me.

Technicalities:
Timeless excels in technicalities effortlessly. The presentation is quite open and airy. Stage has nice width, with very good depth and acceptable height. It’s most evidently not an intimate sounding iem, the expanse of stage feels very naturally spacious.
Separation, as already hinted above, is exceptionally good in this price range. There is absolutely no congestion anywhere. Imaging is very nicely done as well, different sounds are layered pretty well in their own defined positions in the headstage. Even on a busy track, nothing overlaps anything, everything plays nicely from their own position and all the different sounds are easy to pinpoint in the space.

Comparisons:

Vs. Yanyin Aladdin:
  • Timeless has sharper notes, Aladdin notes are slightly smoother, but still enough crisp
  • Timeless Notes are a bit leaner, Aladdin notes are a bit fuller
  • While details are similar, Aladdin notes are a bit bigger, but mostly in the midrange.
  • Due to the leaner notes, Timeless has a bit more airy sound than Aladdin as there is more air between the notes. Separation is noticeably better on Timeless as well.
  • Width of the soundstage is slightly better on Timeless, depth is better on Timeless, while height is slightly better on Aladdin. Aladdin has a more intimate presentation because of the forward and bigger notes, while Timeless presents the music in a more spacious manner because of the increased amount of air.
  • Timeless has a more v-shaped sound, adding a bit more depth to the stage. Aladdin has slightly more forward mids.
  • Bass of Timeless is VERY good, goes deep, sounds full bodied, and yet has enough speed not to muddy the midrange. Fast, big, juicy bass - loved it! Aladdin has a much more controlled bass response compared to Timeless - midbass has less emphasis and sounds less full bodied, although not hollow.
  • Aladdin has a slightly warmer tonality, Timeless has a slightly cooler tonality.
  • Treble responses of both are very comparable extension-wise. Timeless has distinctly more brightness and sharpness and more energy in the table region.
  • Timeless has a slightly cleaner and darker background than Aladdin.
  • Overall, Aladdin gives a comfortable listen with enough crispness not to sound dull. Aladdin is on the other hand full on steroids and providing a fun sound with boosted low, high, brightness, and separation.

Conclusion:
7Hz has truly hit it out of the park with Timeless. I always had an idea that planar magnetic drivers cannot move as much air as dynamic drivers and hence will never have that DD slam and physicality. Timeless proved me wrong. The impressively deep and full-bodied bass performance coupled with the highly transparent and bright mids and treble presented in a very open and spacious manner is bound to sweep the listener off his/her feet at the first listen - it surely did me.
That said, on longer listening, I could feel that the brightness was eating at me. It’s not letting me settle down, always keeping me on the edge in anticipation of the next energetic passage. This is not a feeling that I look forward to. Hence, despite the impressive technical performance, it misses out some of the musicality and engagement factor for me. But I can see how it will satisfy quite a considerable group of audience out there.

However, I must say, one thought has been constantly on my mind since then - If a 14 mm Planar Magnetic driver can be used for a iem with such an impressive tuning within such a lucrative price tag, what can be done with a similar sized DD? I, for one, will definitely look forward to it if someone decides to develop it, even if at a higher price tag.

The general consensus with regard to planar technology especially with regard to iems was that it is objectively superior to single DD, with the caveat that correct/pleasant is a very difficult objective to accomplish. Reviewed like BGGAR and Crinacle have expressed such opinions and many others including those here at Headfi. The 7hz Timeless gained popularity more for its very pleasant tuning that makes eq optional rather than mandatory as it was with a lot of iems.

As for a large DD driver of 14mm or larger. It had been done before. The discontinued bass monster Sony Xb90ex, had a 16mm single DD driver. At present, however most single DD are either 10mm or 12mm.

Good review by the way!

TIMELESS 7HZ – PERFECT EXECUTION
Pros: Well Executed Sound Profile
Authoritative Low End
Tonality and Timbre
Shimmery Highs
Staging
Cons: Recessed Midrange (INSTRUMENTS)
INTRODUCTION:

7hz, a brand which is pretty new to this ChiFi audio industry has released its debut product with some spectacular specifications for the price especially with a Planar driver named TIMELESS. The Timeless looks spectacular in design and feels very premium in the hands but does that replicate in the sound too? Let’s check that out in this review.

pL6fjDn6pT_Ec9u0RT-tEMwXW6NsuVaeSfV_ZuO-QY85ZJBCIZDCANFI5gPAcZw67Gqi0u14Wpt9mNsr_4XxB16BwBB73Jgpu1jdsrgqsVH_e1fgI-vyhbhYvmFm7Q


DISCLAIMER:

This unit has been provided to me as a part of a review circle in my country organised by HiFiGo and thanks to the team for adding me in. This review is my observations over the product after using it for a period of time hence no one influenced me to manipulate this review. My observations are based on my sources of pairing hence this might differ from person to person.

SPECIFICATIONS:

Driver: 14.2mm planar driver

Impedance: 14.8ohm

Sound pressure level: 104dB/1Khz

Frequency response range: 5-40000hz

THD: <0.2%/1KHZ

Connector: MMCX

Nozzle diameter: 5mm

DESIGN AND FIT:

The design of the Timeless is pretty unique where the faceplate is disc shaped and many might think that this looks huge and will they fit? But surprisingly they fit very nicely and are isolated from most of the external noises without any issues. The nozzle is of good length and the provided tips are very nice in terms of comfort and fit.

The provided cable is very good and can be bought in different terminations as per your wish. The cable has that nice supple nature and the premium feel it gives is very good. A nice sheath is given over the cable thus it reduces the microphonics. The cable termination is well protected with nice strain relief and is built strong . It has a nice metallic splitter and the provided ear guides are very soft and easy to adapt to your ears.

SOUND:

The sound profile of the 7hz is a U shaped sound but during my listening they fairly sounded much balanced with emphasis on the sub bass which is the sweet aspect and we will talk about that in the next section. The presentation feels very wide and grand meaning the staging felt exceptionally big in every aspect. In this review let's dive into the in depth sectioning of the audio.

SOURCE:

iPhone + Zorloo Ztella + Zen Can + Avani DAC

LOW END:

The low end of the Timeless is Just sublime. In one word, it's “FANTASTICO!” Both the sub and the mid bass have nice impact and the technicalities. The planar type of bass is very addictive and their presence is very authoritative.

Usually the planars do have the best low end response but they require a hell lot of power to unleash it but the Timeless is the only exception where you can enjoy the planar bass just via your smartphone itself.

SUB BASS: Deep, well extended and growls as much as possible without any distortion. The sub base impact, attack, presence and the weight are unmatchable in this price range. The previous king is the OH10 and man this just defeated it by its presence where the sub bass just growls without sacrificing the technicalities aspect like the separation, control and the texture. In the track “BIGFOOT – MALFNKTION”, the track is rendered out just beautifully. The sub bass drops and the weight is just sublime. The authority of the bass is very present and the control, texture are outstanding. The background instruments are neatly brought out without any congestion. The separation and the staging is just immersive. The depth of the staging can be evidently felt here where the drops sustain for a longer period giving that nice rumble while still maintaining that sparkle of the cymbal crash and the kick drums in the background.

MID BASS: They are not as thick as what some bass head iem does instead they sound very clean and detailed while still having that enough slam, weight and the attack. The speed of the mid bass is impressive hence the separation and the clarity is phenomenal. The mid bass never overpowers hence the midrange is not affected too. The bleed is null and the speed of the low end is impressive here yet maintaining that satisfying rumble. In the track “INSTANT CRUSH – DAFT PUNK”, the faster track is well handled by the Timeless and those kick drums got excellent weight, body and the attack.

Overall the low end is excellent with the sub bass emphasis giving that enough rumble, mid bass being a less dominant gives that clarity and separation in the low end. The attack and decay are precise thus the bleed is not that noticeable. Just one of the best low end i have heard at this price point.

MID RANGE:

The mid range of the Timeless is neatly done. They are not on the face type rather they are positioned at a very good spot for comfortable listening. The energy and the engaging factor is nicely present and those vocals have that natural and smoother tonality which is very pleasing. The timbre of the instruments are near to realistic and no metallic taste is found.

Both the male and female vocals have enough body coming from the mid bass which is not excessive nor too low, instead the body is on the point. The warmth is more than enough and that sweet spot made the vocals very pleasing rather too boomy.

The instruments however slightly feel pushed back in the staging but they are not that evident. Small percussion and stringed instruments may get lost but overall the presentation is done very well. Has a good amount of separation and the detail retrieval is above average. The layering is done well too without any in the head feel where the instruments are placed nicely one behind the other.

Tracks Used:

  1. Take Me Home – John Denver
  2. When You Say Nothing At All – Susan Wong
TREBLE:

The treble of the Timeless is another excellent aspect here. The airiness it possesses is expansive and the open goodness is sweet. This gave a nice separation and detail retrieval to the timeless. The cymbal strikes are very realistic and both the attack, decay are on point.

There is no noticeable sibilance but this is just based on my observation since some of the users noticed it seems. The highs are extended well with a nice open sound. They never feel congested and the brilliance, shimmer on the top is brought out very well.

The stringed instruments sound very nice with excellent timbre. The keystrokes and the guitar strings pluck can be heard very clearly. The trumpets and the other air instruments possess a nice position in the Timeless.

Overall the highs are well open in nature with above average detail retrieval and separation combined with that natural tonality and timbre. It's non fatiguing for a longer listening period while bringing out that nice shimmer on the top.

Tracks Used:

  1. Something Happened On The Way To Heaven – Phil Collins
  2. Sultans Of Swing – Dire Straits

TECHNICALITIES:

STAGING: The staging is one among the widest. In terms of width they appear very open and wide enough. The depth is satisfyingly deep enough and thanks to that nice low end presence. The height is above average too. Overall they don’t feel in the head type or claustrophobic rather they feel well expansive and grand.

IMAGING: Felt very precise in terms of positioning of instruments even in the busy tracks. No clumping of the instruments is seen and the transient response felt very smooth. The channel sweep felt nice and smooth and no 3 point imaging was seen.

The detail retrieval and the separation are above average. Even though they don’t compete with the All BA IEM’S being a single planar, these sound really good with enough detail retrieval.

Tracks Used:

  1. Hideaway – Jacob Collier
  2. Sirens Of The Sea – Ocean Labs
  3. Crossing – Yosi Horikawa
  4. Mountains – Hans Zimmer
VERDICT:

Timeless, the latest and the introductory entry from the new brand 7Hz is a well executed package. The brand being their debut product has done an excellent job by giving the Timeless to the market. The Timeless is a unique looking IEM with a disc shaped faceplate which surprisingly provides an excellent fit. The accessories they provide are abundant and especially that metal case which is very sturdy and elegant.

The cables are available at different termination which is good in quality. Now to the sound they are FANTASTIC. The brand with its debut product went with the Planar instead of a dynamic or hybrid which is a pretty bold move and that too easy driveability! The Planar in the Timeless sounds one of the best for the price. Low end with nice sub bass presence, mid range with exceptional tonality and timbre, highs with good open sound gives the Timeless a strong lead over the other competitors in this price range.

The brand’s Timeless being a debut product they have built and made to sound excellent in every way and they have PERFECTLY EXECUTED the Timeless to take its place in the ChiFi market.

7Hz Timeless - Good Planar magnetic IEMs
Pros: Very Good bass response.
The stock cable and case are of very good quality.
Impressive detail retrieval, soundstage, and resolution.
Cons: Requires tip-rolling to handle sibilance.
Large drivers may cause a fit issue with smaller ears.
Disclaimer:

The 7Hz Timeless was sent to me by HiFiGo.com as part of a review tour in my country, in exchange for my honest opinion. I am neither paid by nor affiliated to HiFiGo or 7Hz in any way and have no incentive whatsoever, for writing anything positive or negative about the IEM. The views shared in this article are my personal views based on the week or so that I spent with the 7Hz Timeless.

The 7Hz Timeless can be purchased from HiFiGo through the following link:

20211112_222159.jpg


Unboxing and Aesthetics:

The 7Hz Timeless comes with a variety of silicone ear tips and a cable that has a mix of single-crystal copper and silver-plated copper cores wrapped in silver foil. Although I was able to get a good seal with the stock ear tips, I still felt like the 7Hz Timeless requires some tip rolling (more on that later). The stock cable is not the softest cable but is definitely premium in terms of both aesthetics and sonic performance. One can choose to go with a 3.5mm SE termination or a 4.4mm Balanced termination based on their gear. The unit I received came with a 4.4mm Balanced termination, which in my opinion would be the ideal choice, especially because of how well the timeless scales with power. The metallic case provided with the 7Hz Timeless is very good in terms of build quality and looks really good too.

The IEM itself is well built and uses aviation-grade aluminum to house the rather large 14.2mm planar magnetic driver. Given how large the IEM looks, I was surprised by the weight (or weightlessness) of this thing. My only experience with a single planar magnetic driver IEM prior to the 7Hz Timeless was with the Audeze iSine 10. Although the iSine10 isn’t exactly heavy, I was pleasantly surprised since the Timeless is definitely lighter than the iSine 10. The fit wasn’t a problem for me and given the shape and weight of the IEM, I don’t think it will be a problem for those with smaller ears either. The nozzle is quite long, hence the large drivers remain comfortably out of the ear. The cable has angled MMCX connectors (quite similar to what we see on FiiO cables like the LC-C or LC-RC). The faceplate is free of any artwork with just the IEM name displayed on both sides. As corny as I might sound, this gives the IEM a “timeless” look 😊.

20211112_203033.jpg



Tip-rolling:

Unfortunately, the stock tips (all the varieties) make the IEM sound too bright and/or sibilant in most cases. Hence, I would definitely recommend tip-rolling when it comes to the Timeless. I tried a variety of tips including Spiral Dots ++, Spiral Dots SF, Sony Triple comfort, Flare Audio Universal, Flare Audio Everyday, Flare Audio Audiophile, Dekoni Mercury, Dekoni TWS, Spinfit CP100, CP145, CP360, and Radius Deep Mount. For the Timeless, I’d recommend Flare Audio Universal if you’d like to tame the treble to a large extent giving it a slightly bass boosted signature. Else, I’d recommend the Dekoni Mercury tips if you’d like something more natural sounding with a good balance across the lows, mids, and highs.

Sound Impressions:

Lows:

The Timeless has some really good bass response. One of the first things that I loved about the iSine10 was the almost infinite depth it had when it came to bass. The Timeless retains a similar characteristic without the bass being too prominent overshadowing the rest of the frequencies. The bass body has very good quality and quantity with that distinctness of a planar magnetic driver. In my opinion, planar magnetic drivers are capable of perfectly reproducing that distinct sound of snare drums which somehow most of the single DD and Hybrid IEMs that I’ve used to date, have failed at recreating perfectly.

20211112_222336.jpg


I especially enjoyed listening to these tracks on the Timeless:

Mindfields – The Prodigy

Smack my bitch up – The Prodigy

Breach – Black Sun Empire

One can really feel the energy of these tracks with each drum beat sounding as distinct and real as it can get. Just give a listen to Breach from BSE on your existing IEMs and see if you’re able to distinguish between open and closed hi-hats in this track. If you’re not able to (but would like to) then the 7Hz Timeless is a definite recommendation from my side.

Mids:
The mids on the Timeless are quite natural sounding. Here again, if you’re someone who likes the timbre of planar magnetics, you won’t be disappointed. I personally felt that the vocals were well done, especially with the Dekoni Mercury tips since they tamed the shouty peaks quite well resulting in a well-balanced sound signature. There was no bass bleed and everything sounded natural for the most part.

20211112_222628.jpg


Highs:
The highs on the timeless are engaging and complement the overall signature quite well. I felt that there is plenty of detail here but IMO the extensions were tamed/neutered perhaps because of my choice to use foam tips. Not that the Timeless lacks extensions, but, based on my limited experience with the pair and my limited understanding, I believe there is a trade-off of sorts in this case. One can either use a pair of memory foam tips to tame some of the shouty peaks in the upper mids and lose some treble extensions in the process or use a pair of silicon tips (perhaps wide bore) for the treble extensions (with the aforementioned sibilance). I was hoping that a pair of wide-bore foam tips (like Flare Audiophile) or the amazing hybrid JVC Spiral Dots ++ would fix this, but I preferred the overall sound with the Dekoni Mercury tips over the aforementioned ear-tips. However, since this is (of course) heavily dependent on perception and preferences, I will recommend tip-rolling.

Technicalities:
The soundstage is quite wide and the dynamic range is more deep than tall IMO. Although the Timeless can be driven quite well off a smartphone, it seems to scale well with amplification. As with other planar drivers, I observed that the resolution improves significantly with amping. The 7Hz timeless sounded heavenly off the FiiO M11 Plus LTD stacked with the HUM MA1B via Balanced Line Out. The immersion and details were extremely engaging and the timeless really shined on this stack.

20211112_221939.jpg


Conclusion:
All in all, the 7Hz Timeless is a well-implemented planar magnetic IEM that has an excellent bass body with equally good mids and detailed highs. Just remember to tip-roll, if you find it slightly sibilant or shouty as I did. 😊

Headphoneus Supremus
Pros: Stellar value at $220!
Best tuned planar IEM to date, and its not even close.
Good resolution and spatial qualities at this price point
Cons: Can be a tad bright at times, or with certain tips
Low end resolution is just average, and can be a little blunted.



Balanced tonality, crisp airy soundstage, rock-solid imaging, quick transients, punchy, slammy, and good dynamics with a decently wide soundstage. These combined terms don't typically come from me on most of the review units I receive, much less ones that are priced in the affordable range and by an obscure no-name Chinese brand like 7Hz. But, so it is.

I have never heard of 7Hz before, and Lillian from Linsoul asked if I wanted to try out this new planar magnetic driver in-ear monitor earphone called the "Timeless" several months back. As some may know, I enjoy my fair share of planar magnetic over-ear headphones, and have owned several disappointing in-ear planars in the past, and have demoed, reviewed and painfully listened to most of the ones on the market to date.

All of them are tuned terribly. Very few of them can be fully saved by EQ. The ones that do though can be technical beasts like the Audeze LCD-i4, but again, requires some sort of EQ capability on the go. Yes, Audeze packages their units with the optional Cipher cable, but that also requires a soon to be outdated lightning jack limited to iPhones and older iPads. Android users can get by with an Anker adapter but can't tune the Cipher since the App is iOS exclusive.

Enter the Timeless. It's all the things I mentioned in the first paragraph, and a shockingly good IEM at just $219 with a well thought out package to boot. Let's talk about it some more.



Unboxing​

The Timeless comes in a simple box that feels a bit more weighty than one would normally expect out of an IEM package. The reason for this is because there a hefty machined aluminum hinged-flip-top box that is included to store and carry the Timeless in. It's a very nicely designed and finished case that should hold up to even big drops, while also feeling very luxurious and premium.

The Timeless also includes a series of tips and a silver-colored 2-core braided cable that I absolutely love. It's very lightweight, but feels and looks premium. Its the type of design choice I like and is similar to the same cables I bought from XINHS on Ali Express, except the Timeless cables have more premium connectors and splitters that are metal and color-matched to the black and red shell housing colorway.



The Timeless itself is a 14.2mm planar driver within the round disc-like aluminum shell. The driver size puts it smaller than my very own Unique Melody ME1, and the Audeze series of iSine/LCD-i4 and i3/Euclid, but however, it is larger than the RHA CL2, and the various Tin P1, P2, and other recent chi-fi planar iems.

At this size, it looks perhaps a bit intimidating; not as much as when I got the iSine and ME1 several years ago, but more so than other IEMs. But Timeless made this set very lightweight, and incredibly comfortable for my ears, which don't jibe well with certain IEMs. Surprisingly, I am able to wear this unit for several hours without any discomfort. I haven't had a chance to really see how long I could go, because I'm always interrupted by meetings or other things during the course of a typical day, but it's one of the few IEMs that I never feel when I'm wearing.

Sound Impressions​

Not feeling any discomfort is a good thing, because the Timeless sounds really good. It's rare that I have no urge to take off a random review sample that I never heard of before, after hours of listening for an entire week. There were times when I was grooving to jazz band, Go Go Penguin, or soul artist, Celeste, between meetings and begrudgingly had to take the Timeless off to attend to my calls.

Part of this was because the first time I put the Timeless on, I was immediately shocked that I heard a planar IEM that was tuned to be listenable without EQ straight out of the box. And not only that, but this was tuned better than MOST IEMs I've heard, no matter the driver configuration. It's just tonally balanced to my liking and if I had to describe it, I would say that it's perhaps a tad too elevated in the low end, but is very punchy and dynamic with a steady mid-range and an upper treble region that is right on the spot in terms of balance. The treble range is well-extended but can be just slightly north of neutral, but that also helps provide that dynamic sense and added excitement, while never sounding sibilant to me (YMMV, see more below). It's just a well-tuned device.




The Timeless's biggest weak point perhaps is that its not the most resolving planar out there. That belongs to the Audeze LCD-i4, which is priced 12 times more. But even so, it is still resolving, but maybe not enough for how much bass level it has. If I had to really nitpick, I'd say that the bass is just slight too much at times, and because it isn't the most resolving, or the fastest in transient speed here, that it comes off just a little blunted or lacking definition at times. To simplify it all, the bass range sounds more rounded than I would like and missing the final layers of depth and detail.

But that is nitpicking it down, because I find most everything about the Timeless to be very strong, and given its price, this is maybe a no brainer purchase for those looking for a "low-priced" IEM with high-priced sound. Wow, I am sounding very shilly in this piece, and that's not normally my style, but I have come away very impressed on this unit!

The other nitpick that I think some people may find with this is that the treble is a little spicy. I've heard that some do find it a little too bright, but for me, it's not a thing. I find its treble tuning to be smooth for the most part with good extension that really lets me hear those closing resonance of cymbals and hi-hats and strings of the jazz and bluegrass music I frequently listen to in my review playlists and my typical relaxing listening sessions.

If there was specific area where one may find this a bit on the harsh or aggressive side, I'd say that I found some brass instruments and saxophones to be a little more forward and more personal than maybe I want to on many jazz tracks I heard. I never found similar issues with female singers, though I've read about such things on the various forums. It could come down to tips, insertion, or general tolerance for treble sensitivity.




Wrap-Up​

For just over $200, the Timeless is one of my new reference IEMs for this price range, maybe up to $500, as you start heading into Dunu SA6 territory. The Timeless really sets itself apart from the rest of the pack here with a good balance of tonality and technical performance where many of the attributes that make planar driver special seem to come off with this unit -- that is: quick speeds, solid resolution, separation and imaging. And even then, it can actually hit pretty hard with its elevated bass.

Add to that a nice carrying box, and a simple but attractive cable, and I think the Timeless really hits it out of the park. 7Hz, good job!

Great review! Glad you mentioned that tips can change the perception of harshness. I've found from tip rolling that a treble peak in my Timeless could go anywhere from 5khz to 7khz or even disappear completely, depending on the tips I used. It boils down to insertion depth and the resultant ear canal resonance frequency. Hardly the fault of the IEM. So folks, you know what to do.

500+ Head-Fier
7Hz Timeless : The elephant in the room
Pros: 1. Mild V-shaped, allrounder sound signature
2. Elevated Bass, mostly focused in sub-bass
3. Slight forward upper mid-range
4. Neutralish well extended treble
5. Very good build and has premium feel to it
6. Lavishly accessorized
Cons: 1. Sibilant at times with multiple tracks (Stock Tips)
2. Bass has a soft touch to it as per my taste
Introduction:
7Hz , aka "Theta wave" is a team of engineers enthusiasts bound by their common love of music and an idea to summon musical trance through their equipment. Timeless has got a lot of attention these days in all the audio forums as it one of the few planar driver IEMs out there.

Each timeless earpiece is cut out of aviation-grade aluminum alloy material and then shaped using a high-precision CNC machining process followed by the highest strength level of hard oxidation treatment. The result is a product with a high aesthetic value along with ergonomic comfort. The metallic earphones have a raw charisma to it. Perfectly round faceplate engraved with concentric circles give another worldly appearance to it. The overall look and feel is classy and stunning.

7Hz is bundled with a silver-plated single crystal copper inner core with a silver foil outer layer. Its smooth and complements the earpieces perfectly. The carry case is very sturdy and feels like a rugged brick of aluminum (brushed metallic design) with promising safety of IEM and gives an extra edge to the overall premium feel. It also comes with an extra pair of nozzle filters in case anyone damages stock ones while cleaning or modding it.

Fit wise there is no need to be afraid looking at the huge size of disk, as per my opinion its more of an aesthetic thing that remains outside the ear, the insides of IEM are neatly designed for the comfortable fit and get support from the ear canal. The earpieces are quite light weight and does not cause any fatigue even for long listening sessions.

The IEMs are very energy efficient and doesn't require any external amplification to shine out.

Disclaimer:
I have received Timeless as part of review circle from Hifigo in exchange of honest reviews. All impressions of sound are subjective to my own listening and my sources and is based on my experience with IEMs of similar hardware configurations and price range. One can purchase the same from the following link.

Highs:
In this price range I would say it's one of the best treble extension I have heard so far. All thanks to the planar magnetic driver. It is not overdone, to be distracting. DDs normally tend to suffer in this region but this using a planar driver is able to do the job done effortlessly and helps to add the required micro contrast to the sound. But a downside here, it came out sibilant at multiple times on various tracks.

Mids:
Timeless is not at all mid-range focused IEM, instead the major focus areas are the treble and the sub-bass regions. There is a slight elevation in the upper-mids. Tonality wise I do felt it performed very well given the price range.

Lows:
It's not a bass head IEM for sure but it does have ample quantity of bass. The major focus is towards the sub-bass region. The bass characteristics are full of texture, punchy and full bodied. The bass is very much controlled. The mid bass does also have a nice texture to it along with speed and details. Overall bass is nice but feels bit soft to my taste.

Technicalities:
The details and micro contrast is very good on it. Soundstage has an environment feel to it for which most of the planar drivers are known for. The layering and separation is quite good for the price. The microdetails and micro contrast is very good as this price point of view.

Final Verdict:
7HZ Timeless has a fun and engaging sound signature, there is an elevation in bass but not at all overdone, I would say there is a balance between quantity and ability to regain the details. Overall bass feels bit soft as per my taste. The tonality is very good with nice with good layering and imaging capabilities. The treble is nice and crisp with good extension to it. These are not at all reference monitors but designed to make the music sound very much enjoyable. The build is very good, comes with a very premium and sturdy case which stands out at first glance. Cable is also of very good quality, although bit slim and tends to tangle a bit and comes with either 4.4mm or 3.5mm connector. The best part is that it's one of few planar IEMs out there which are great in tonality that are very much energy efficient and doesn't require any external amplification to shine out; although I would recommend to use foam tips as of the sibilance factor I have observed with the stock ones.

Comparison:
Well I have been using Tin Audio P2 for quite a time and it has been my daily driver for my night setup which to my opinion beats a lot of top mid-range IEMs as per my taste in music. I should not be comparing these two as there is huge price difference between these two, but as this is new elephant in the room so why not. Performance wise I liked that Timeless is very much energy efficient and unlike P2 it doesn’t need any additional amplification to shine out. Both of these suffer from sibilance with the stock tips, rest talking in terms of sound quality for me P2 is an excellent performer in terms of mids and lows, where as if we talk in terms of extension in treble, timeless performs effortlessly but P2 given proper amplification gives much more air and micro contrast in this region as well.
