7Hertz Timeless

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.



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.

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.

My Setup
DAP: Hiby R3 Pro Saber through 2.5mm balanced port
Stock cable changed for BQEYZ 8 core silver plated 2.5mm balanced cable (only because there is no 2.5mm stock cable option provided by 7hz)

The feedback on this iem by BGGAR and the unbelievable impressions of this by Crinacle made me take a leap of faith and purchase the 7hz timeless. Suffice it is to say that, my trust in these reviewers was not misplaced. For about 6 months now, I have been using a Hifiman Sundara on my desktop audiophile setup and have been loving its sound signature. When sufficiently powered ( I am driving the Sundara currently using the Xduoo XA10 Dac/Amp through the XLR balanced port), Sundara has a full sound signature with tight bass, forward and lush vocals and crisp but non-fatiguing treble. The sound stage is also immersive though not the widest by any means.

Running the 7hz Timeless from the 2.5mm balanced port of the Hiby R3 Pro Saber Dap in high gain reminded me a lot about the sound signature of Sundara. Similar tonality with the sound stage taken down a notch but still retaining its immersive quality. I am not sure what gives the Timeless its very immersive sonic qualities despite it being a closed-back iem. I take it to be an overall result of the combination of its sub-bass extension, forward vocals as well as great instrument separation and clarity. Not to mention the crisp and detailed treble. The width of the sound stage is comparable to something like the Fiio FD3 Pro. One can easily feel the musical notes travelling from extreme left to extreme right and vocals taking the central stage in various tracks. However, the soundstage limitations of this being a closed-back iem still applies. Tracks with a lot of instruments and atmospheric sounds work especially great with this iem.

However, this iem though it works great with all genres of music may not be great for everyone. For example, bass heads may want more mid-bass punch. Similarly, those who are fans of a warm and dark sound signature may not appreciate the crisp, forward and detailed treble on offer here. The comfort of this iem is also not the best even though the fit is great.

To conclude, this iem is great for everyone who can live with its slightly less mid-bass punch and find its comfort to be good enough. Of course, using a quality equalizer can help as well!!

Disclaimer
Recently I got chance to audition 7z timeless planar iem which was organised by hifiGo.com in india. I m not affiliated or tied up with brand or seller ,all impressions are based on my own personal experience. And I m happy that I got chance to audition this beauty. Thanx a lot hifiGo for arranging this tour. I ordered my personal Unit with my own money on the same day I got unit in my hands after listening it briefly



Box, packaging and accessories
7z timeless planar iem came with small minimalistic box which contains iem itself , plenty of tips , very sturdy metal good-looking iem box with magnatic lid,cool isn't it ?and yeah very good supple 4.4mm balanced cable.3.5 mm cable also available as option in case anyone wants it .few papers ,and an extra pair of nozzle filters



Build quality and design and fit
7z timeless built with high quality aviation grade cnc machined aluminium shell in round shape which is very comfortable for my slightly larger ears Build quality feels solid and premium yet very light weight,no comfort issue at all.



Specifications
7z timeless built with 14.2mm Ultra thin diaphragm planar driver coupled with powerfull Double sided N52 Neodymium magnet.which has 14.8ohms impedance and 104db of sensitivity Resulting very easy to drive ,infact one of easiest planar magnetic iem available in market. I believe these drivers are derived from another planar iem PMV PP (very similar specs) which is not very popular imo



Sound impressions

Alright let's talk about sound , Despite of being closed back iem this beast sounds like open back overhead headphones, although not as spacious as some full size planar but still it feels like full size headphones. Bass is main USP of timeless , it produces kinda big hefty bass almost feels like sub woofer type , slightly faster than DD but but not as attacking and punchy as some very good dd iems out there but hey it's a planar not dd and you might alredy know producing good satisfying bass in a planar iem is very difficult and I mean it. also bass is slightly softer side ,subbass is very satisfying and we'll extended , though not thieaudio monarch level or basshead level but yeah it is enough for bass lovers.all over bass is elevated , emphasized but thats ok ,not annoyingly emphasised though. But yeah it's more thn my liking ,or more thn anyone can ask from a planar iem :-D .mid bass also slightly softer than my liking but bass details and cleanliness is on another level. Mids are very pleasing ,both male and female vocals are felt good and joy to listen, though vocals are slightly laid back, plays from little distance. not felt mid forward presentation. Mids clarity and details are very good. Highs are energetic, detailed and airy ,some says it's slightly bright but I didn't felt anything like that , string instruments felt true to nature and life like , resolution is on whole another level , yes very resolving , no surprises it's planar after all. Soundstage is above average not overly wide nor intimate , yes depth seems little bit lacking here but, imaging is more thn above average ,very good. I tried it with gaming and no complain in imaging , directional clues , foot steps everything cristal clear. Also dynamics are very good for it price segment no complain at all. Well tonality is v shape and timbre is very good ,no plasticy timbre felt despite of being planar , it's more like dd rather thn Planar. Though somehow slow rebound foam tips improves it's timbre a lot , also reduces depth problem. All over coherency is good. Not feeling disjointed on all over frequency spectrum response. No cohesion is not Andromeda or Solaris level ,don't expect that , but aren't we nitpicking here ?hehe ! Response to EQ is great ,I tried wavelet app for equing and it responded well , do we need equing here? well Nop.Not in most cases, But though I thought I must mention it here in case if any1 wants to EQ lower frequencies :-D I did it actually LoL and results is satisfying. Ok it's enough said now



Conclusion

Well some said timeless is best planar available In market ,Yes I would say it's best tuned Planar yet , which doesn't need EQ in most cases and with most genres.Easy to drive and Bass is its main USP. I tried it with my phone and voila! it's performs well with smartphones 3.5mm jack also but it's gets benefits from power , planars loves power afterall , I tried it with cayin n6ii t01, e01, fiio M11PRO , ifi micro idsd black label and Burson playmate 2 also ..given more power resulting better performance. Timeless is good for movie watching and for gaming also aswell . highly recommend from my side. I m happy with this purchase.



Note:- I burnt it for around 40-50 hours before posting these impressions.

Cable:- stock 4.4mm balanced with cayin n6ii t01,m11pro and fiio lc-c 3.5mm mmcx with smartphone and cayin e01.

Tips:- JVC spiral dot++ and Spinfit (L size yellow 1 i forgot model number lol) And flare audiophile foam tips.

Introduction

Timeless has been the talk of the town recently for being a special entry in the mid budget segment. It houses a planar magnetic driver, which is not something unique, we have seen various renditions of planar driver in IEMs at different price points by different brands. So why is the Timeless talk of the town? The reason being its performance, both in technicalities and tonality. All other planar IEMs that came out earlier, primarily in the sub 1000USD price range, including the hybrids, usually did well with technicalities (not all) but weren’t doing anything special with the tonality. Tin Audio’s P1 was probably the best ever to come out but needed powerful desktop grade setup to shine, even then might leave most craving for bass and/or listeners finding the signature bright. Tin P1 still have a good fanbase even today after years of its release.

We will discuss in detail what makes the Timeless special and what you can expect from it if you decide to spend your hard earned money!

Build Quality and comfort

Timeless has a unique shell. The inside part being smoothly shaped to fit our ear, whereas the faceplate being a flat circular plate. The shells are lightweight, black in colour, made of aluminium and have a smooth feel to it. Fit wise, with stock tips some might struggle but using after market tips like Spinfit CP100, AzlaSedna Earfit Light Short or JVC spiral dots – as per your preference, sorts the fit issues, if any. Timeless doesn’t fit with high isolation creating a vacuum inside the ear, for which I am thankful, not really a fan of that fit anymore. The cable is lightweight too, comfortable, doesn’t really speaks of strength but does the work without and microphonics and tangling. It comes with an assortment of tips- different sizes and shapes, comes with probably the most premium looking case ever made of brushed aluminium, an extra pair of filters, some documentation. Overall, Timeless package is rich in good quality accessories, specially the case, which is a looker!

Score: 9/10


Lows
Probably the primary highlight of Timeless. I haven’t heard such good lows for a long time, most IEMs I tried till date, leaves me overwhelmed or underwhelmed with quantity or disappointed with quality. Timeless is none, its bass is tasty! You get the quantity in the most appropriate amount, followed by the excellent detail retrieval, just planar bass goodness. Bass have decent amount of slam and overall contributes to warmth and enjoyable sound signature of the timeless. On tracks like, Luka Chupi by A.R Rahman and Lata Mangeshkar from the movie Rang De Basanti, there is a bass line playing and coming up at certain intervals: 1:50-2:05, around and after 4:00, its clean clear with great details, most iems either miss it or overdo it making it overwhelming, some of them losing the texture, Timeless did it spot on. My library mostly consists of rock and a bit of jazz and blues and pop, for all these genres, bass plays an important role, it overall makes the music enjoyable, when done in appropriate quantity and quality, just like most things in life!

Score: 9/10

Mids
I’m not a fan of forward on your face kind of mids, mid forward signature probably isn’t suited for my music preference, hence I am always very particular of it. Too much laid back mids aren’t enjoyable either, the lows and highs turn out to be overwhelming when you crank up the volume since most people adjust volume with respect to mids. Timeless portray mids for me in an excellent way, its so appropriately staged, that even songs that sounds shouty on other IEMs were smooth on Timeless. It isn’t because the Timeless is aggressively laid back in mids, its because of the smooth and appropriately forward presentation of the mids. Looking back into time, I remember when I reviewed Blessing 2, it was an excellent IEM with great details, soundstage, tonality, all things done right but didn’t really suit my taste as it was little to mid forward for me. There’s a spike at the 2k region as per the graphs however with burn in, I feel it isn’t noticeable anymore.
Electric guitars, piano, brass instruments, flute etc sounds pretty good, good amount of details and layering in the mid frequencies, probably not the most natural I have ever heard but overall it’s a great balance.
Male vocals have good texture and depth whereas female vocals sound a little flatter, vocals in general sounds smooth with decent amount of texture, probably not the most natural tonality. Vocals doesn’t sound heavily focused at centre, rather smoothly dissipated. Tracks with multiple vocals as well as other instruments playing, doesn’t sound congested, vocals are able to stand out.

Score: 9/10

Highs
Timeless because of its peak at 2khz and 8khz might sound bright and peaky to some (even I observed it initially) but with time, probably with burn in (actual or mental) it smoothened out for me. It doesn’t sound like a peaky or bright IEM anymore, rather a smooth warm IEM with great detail retrieval across all frequencies. The highs are clean and clear, with good air and separation, this is evident from cymbal hits and hi hats from songs like Windowpane by Opeth. Acoustic guitars sound really clean and clear, for eg, the intro section of the song Luka Chupi and throughout the song.

Score: 9/10

Soundstage, Imaging, Separation

Soundstage is the only department where I feel Timeless could have done better, its fairly wide with good height but it could have been wider. Nevertheless, music never sounds congested even with tracks with busy sections like Luka Chupi starting from 4:30. Thanks to the separation and clean presentation, Timeless comes out on top. Imaging is great on Timeless, this can be observed on the song Thriller by Michael Jackson, where right at the beginning the door opens and the footsteps move from left to right, its so clear and can be pinpointed in both width and depth, speaks about the prowess of the Timeless in terms of imaging. Separation is another great aspect of the Timeless, all the above tracks, aren’t very well mastered yet sound clean, separated across all frequencies. This surely impresses me quite a lot.

The presentation here feels like a medium sized hall with the listener sitting probably at the 3rd – 5th row. There’s overall a holographic feel to it, air around the room with the sounds reverbing across the hall. Eg: Heaven (MTV Unplugged Version) – Bryan Adams

Score: 9/10

Tonality

Planar IEMs have almost been technically sound, but Timeless takes it to next level with its great tonality. It’s not, and need not be tonally correct, because it sounds great, with appropriate balance of being critical and fun sounding. It’s not the most natural IEM I have heard, its enjoyable and is a versatile IEM sounding equally good with all genres and better in some. I feel timeless has mild V shaped sound signature with warmth slightly laid back and non-fatiguing sound signature. Its not an IEM that will play the music on your face, rather it will just present the music in most humble way, you can go on hours without being exhausted, enjoying and rediscovering your music.

Score: 9/10

Source and drivability

During review, I have used the following setups:
Cayin N6ii with E02 (4.4mm balanced)
Cayin N6ii with A01 (4.4mm balanced)
Phi DecaDac + Sapphire amp (6.35mm single ended)
Timeless sounds great on N6ii and is fairly drivable. On E02 module, at Low gain the appropriate listening level for me is at 45/100. Its almost same as JVC FDX1.
On Phi DecaDac + Sapphire amp – its sounds the cleanest and best as Sapphire (based on RJMs Sapphire v4 diy amp) is a transparent amp, whereas Phi DecaDac (multi multibit DAC based on tda1387) is a smooth neutral sounding DAC.
It does scale up with cleaner source and power but sounds great even just out of the DAP.

Comparison

JVC FDX1 (blue filter+azlasedna airfit light short eartips) vs Timeless:
Yes, it’s an apple to orange comparison one being single DD vs Planar magnetic, but it fairs as both are around same price range and are probably best in their own little world. FDX1 is my favourite single DD IEM and I preferred it over Fiio FD5.
Timeless has more bass and better bass quality, while Fdx1 has an edge with the DD slam but low in quantity. Fdx1 sounds brighter and lean compared to Timeless which has a warmth and more note weight. Fdx1 however sounds cleaner comparatively with slightly more details. Both have similar extensions on both ends of the frequency spectrum. Timeless has better separation and layering. Vocals are more forward and natural on the Fdx1 whereas Timeless has laid back vocals. Fdx1 vocals texture is more noticeable probably due to its mid forward presentation. Fdx1 vocals sounded shouty at the busy sections of Luka Chupi after 4:30. Fdx1 has a neutral sound signature whereas Timeless has mild V shaped presentation. Fdx1 soundstage seems wider but loses in layering and separation to Timeless. Timeless handles busy and congested music better than Fdx1.


Conclusion:

I have said enough about the Timeless so I will leave the conclusion to the readers. Timeless is priced 225USD and if you ask my opinion, is worth twice the price. Few areas you might want to look at before buying is fit, the mild V shaped sound signature with not so forward mids and the decent soundstage – these might be points of compromise for some whereas would matter for some. From my side, it’s a definite recommendation.

Overall rating: 9/10

Introduction

Timeless is a single driver planar iem. There aren't many contenders in this arena. The most prominent being Audeze iSines. Some would remember the Tin Hifi P1.


Sound


Tonality (8.5/10)

Planars have been notorious for having poor tonality out of the box. Most require some form of EQ to become acceptable. Although the Timeless is no exception, it strike pretty close to home. I'd say Timeless is about 90% correct out of the box. It is totally listenable. The whole curve is calm as a lake, if not for that dual-peaked hill jutting out of 2-3k that makes female vocals and cymbals shreaky to my ears. It looks like a little fedora hat compared to the V14.


le petit fedora hat

The hat is the only thing I have to take off with EQ. Two dBs off 3kHz thank you.

Point to note is that vocal timbre is the specialty of planars. I have yet to hear this level of creaminess coming from any other type of drivers. It's something different from DDs and BAs... a "larger than life" experience that I think every audiophile should hear at some point. Planars feature a heavier note-weight in the mids that is satisfying to hear.

If I had to nitpick on timbre, the bass isn't as dirty as I want it to be. Fast drivers tend to have this issue. The bass seems to decay just half a second too fast, or there is lack of echo. Having said that, I'm grateful enough for the fact there IS such a good helping of bass and sub-bass on a planar.


Resolution (8/10)

Surprisingly clean presentation. It definitely sets a high bar for subsequent iems coming after the Timeless. I've always thought that if someone manages to tune a good planar it's going to beat all the single dynamic drivers out there. At $200, the Timeless is clear a bracket king in terms of resolution.



Soundstage (6/10)

Those familiar with planars would know that they have less-than-stellar soundstage, even for full-sized headphones like Sundara. The Timeless is no exception here and shares this unfortunate trait that comes with the planar bloodline. Sounds seem to come from one single point. Although the focal imaging for vocals is excellently within the head, I find myself thirsting for more separation during the faster and busier tracks.

The Timeless is good enough for my library such as pop and country, but those with a great selection of music from rock/metal, or classical such as complex orchestral where positional cues and brute-force resolution matters a lot to you... then you may need to look at high driver count iems.

-----

Comparisons:

Tin Hifi P1

- Fit and comfort is miles better than P1
- Soundstage is much wider and not as claustrophobic
- Resolution is likely better due to the decluttered soundstage
- Trebles are less stabby stabby, and way easier to fix
- Bass is better both quality and quantity
= Mids are about even

In general I can conclude that Timeless is a total upgrade to the P1. It's fixed the fit and the bass. Now the trebles are still having some issue. (See diagram of Fedora Hat.) But at most it is 2-4dB away from other iems and it isn't a huge difference. It has the P1 mids but also better in everything else.

Conclusions:

It's quite a convincing product from 7 Hertz. Solid sound performance. Decent build and quality. Easily driveable from smartphones. A real portable planar at an affordable price range. Finally we get to enjoy the taste of planar on the go. It's 2021 people, no one's going to stacked amps around with a fanny pack.

PROLOGUE​

It was pure impulse buy for me on this one the moment pre-orders were made available on HiFiGo. Cashing in on my “loyal customer” discount, I blindly confirmed my order in split seconds. As a big fan of TIN HiFi P1, I was already craving for some exciting addition to my Magnetic Planar collections.

The very thing that convinced me to get this 7Hz was actually the curiously intriguing look that oozes with “Blade Runner” futuristic design and the lovely anodized black shells. Yes, I know it’s kind of stupid as I never even bothered to check what are the exact specifications, I worry about that later ahahaha.

The Build:

7hz Timeless is a Double-sided Array N52 Neodymium Magnet, Ultra-thin Diaphragm 14.2mm Magnetic Planar Driver, with astonishing 104dB of sensitivity at 14.8 Ohm. I believe this specification alone makes Timeless the most “easily” driven Magnetic Planar IEMs in the market now.

The shells are made of aviation grade aluminum, CNC machined to resemble a spaceship. The choice of material has a lot to do with sonic tuning as it is for aesthetic reasons. Nonetheless the result is a beautifully constructed IEM that impressed me a lot.

The stock cable, made of hybrid single-crystal copper and silver-plated single crystal copper cores. The cable has an outer shielding with silver-foil wire. This recipe I believe is intended to provide balance in sound signature. My unit comes in balanced 4.4mm Pentaconn configuration with MMCX connectors.


The Wear:

With the rather odd spaceship construction, many were made wary, fearing that this Timeless would look out of place or quite possibly having fitment issues. I am just glad those were unfounded. It is not as big as how the picture suggests. The dominant circular outer shell has been designed not to intercede with proper anchoring of the inner shell to fit the ear concha. It is as comfortable as it can be, and I have worn my Timeless for up to 6 hours on several occasions. The cable, aside from being beautifully made in white, offered great flexibility with very useful chin slider to eliminate microphonics.

The rest of the package include 4 sets of tips of different sizes and material. However, I was a bit disappointed they did not include foam set as would normally be found with other IEMs. Instead, Timeless came with interesting rubber tips that reminded me a lot of reversed KZ Starline tips. I will talk about this more later.

PLAYING IT RIGHT​

This being a magnetic planar I am quite aware of the need to pair it with beefy sources, and I have opted to use the following gear selected from my arsenal of DAC/Amps

• Samsung Galaxy S20 (USB 3.0 Power Delivery)
• Sony Xperia Z5 Compact (USB 2.0 Power Delivery & 3.5mm)
• TempoTec Sonata E44 (4.4mm BAL)
• VE Odyssey HD (4.4mm BAL)
• Ovidius B1 (3.5mm SE)
• VE Run About Plus 5 (RAP5 16.8v Amplifier)
• HiBy Player (USB Exclusive Mode)
• EQ: Always OFF (I never use EQ)

Up until this point of writing, my 7Hz Timeless has undergone no less than 60 hours of Burn-In. The last 24 hours being actual usage and listening sessions. For the most part I left my Timeless on Burn-In loop on my laptop.

THE SOUND

Timbre and Tonality. Okay this can get a bit tricky. I have found out that this Timeless is very dependent on the choice of tips being used. The stock tips that it came with, silicone type, offered what I consider as Neutral Balanced timbre with a tiny hint of V-Curve. Evidently warm-ish tonality that seems to have some hump in upper Mids. To my ears this setup has somewhat dense Mids, fenced by commanding bass responses and sparkly highs. This sounded almost like a DD rather than a Magnetic Planar! Then at later stages I rolled the tips and was pleasantly surprised with less colored presentations offering Neutral Balanced sound with Misodiko Foam tips. But it does not end there, when I swapped in the narrow stock rubber tips, the entire spectrum of timbre presentation now edges very close to Diffused Field Neutral! Ahahahaha, I can’t hide how happy I was with that. Being a DF Neutral junkie since forever, I totally digging the sound with that tips. It is freakishly close to the timbre and tonality of my Shure KSE1500 now in that configuration, the TOTL reference sound that I madly adore.

For a magnetic planar, 7Hz Timeless offers good airy timbre as compared to TIN HiFi P1 (which sounded almost airless), FOSTEX T40RP MK3 and Monolith M565c. Again, I am hearing something which is more common to Dynamic Drivers or Electrostatics (true Electrostatic). But of course, not as much but enough to feel the sensation of air between the notes.

Dynamics. 7Hz is a very vibrant unit for a Magnetic Planar IEM, as simple as that. I believe the large 14.2mm diaphragm has a lot to do with this. Compared to the 10mm of P1, which can be quite lifeless and lean if not powered properly, 7Hz is quite the opposite. Even my old Sony Phone 3.5mm was able to drive the Timeless with impressive output offering wholesome dynamic range that is coherent and engaging. There’s ample density and note weight to not sound lean, recessed or anemic, which is practically impossible for P1 and T40RP MK3 on that same Sony phone. When powered properly, I am greeted with rich dynamics density and note weight with lots of headroom.

Mids. As noted above, this is also influenced by the choice of tips. I honestly was not very fond of the stock tips presentation as it exhibited some peaky moments on upper Mids section especially with male vocals and guitars. While it sounded natural for the most part, that “hot” zone forced me to notch the volume 1 or 2 clicks down. But then perhaps this is due to my Timeless being still at early stages of Burn-In. My P1 needed at least close to 200 hours to behave properly and not exhibiting any hot spikes. Not forgetting the somewhat unnaturally “honky” vocals I get on some songs (Morrisey & Nick Cave), at least this is how I interpret it with my own hearing.

With the foam and rubber tips, all the issues stated above, all gone. The Mids sounding a LOT more neutral and less aggressive. No longer obstructed by the annoying thick overlay, details and textures started to emerge audibly. Proper natural sounding attack and decays, be it vocals, instruments, or percussions, all sounding correct and realistic.

Treble. At least this section is a bit more consistent regardless of which tips I use. With proper pairing of sources, Timeless did not disappoint on Treble quality. I am very satisfied with the smooth, crisp, AND airy Treble presentation, offering rich details, texture and extensions which is only outclassed by my Shure KSE1500 and VE Duke. Otherwise 7Hz Timeless assuredly score slightly better against TIN HiFi P1 and Etymotic ER4SR (OMG I am admitting something is better than my longtime love ER4SR). Going back to the tips selection, while with the stock silicone, it is a lot crispier. With the Misodiko foam and stock rubber tips, it has slightly less sparkle replaced with smoother decays. In current configuration that I am hooked with, Treble is addictively creamy smooth and polished with very clean realistic decays expected of a well-tuned planar. This is better than most DD Treble presentation which to my ears sometimes can get a bit too “exciting” – which in turn translates into listening fatigue. Yes, no Treble fatigue from 7Hz Timeless.

Bass. This is the best part. 7Hz has lots of respectable bass body mass. But not too much that it would upset a DF Neutral lunatic like me. I am actually shocked finding myself enjoying the deep, greatly textured bass responses. This was sorely missing from my P1, I wouldn’t deny it. With the stock silicone tips, Mid-Bass offered visceral commanding punch and speed. However, at times I found it to be overbearing especially when listening to Alison Krauss & Union Station’s “Lonely Goes Both Ways”. Several tracks on that album has pronounced bass layers that sounded unnaturally strong to my ears. Not forgetting that the commanding Mid-Bass presence also meant that the Sub-Bass extensions seemingly drowned from audible hearing. To attune to my taste, again the Misodiko foam and stock rubber tips fixed that for me. Now Mid-Bass has been tamed admirably with less punch, allowing the Sub-Bass to be presented audibly with sweet seismic sensations. I know that the current configuration is the correct one, I spent hours calibrating the tips to match the bass presentation as close as possible to KSE1500, serving as my reference.

Details & Transparency. 7Hz Timeless is a very competent performer in details retrieval. The more technical the sources, the better the performance. There’s pristine clarity in the handling of Macro and Micro details. This was proven with Sinne Eeg song “We’ve Just Begun”, one of the most complex jazz masterpiece in my collection. Saxophone, Trombones, Piano, Cello, etc. the whole composition of that song has lots of details all over the place – it just need a competent listening device to hear them all. And 7Hz Timeless didn’t miss anything.

On the subject of transparency, this is where I have slight mixed feelings. Timeless offered great transparency to the point of revealing recording and mastering artifacts especially in the Treble section. On some recordings I was slightly annoyed by grainy edged Treble decays contained in the songs. The only way to mitigate this is to limit the usage of 7Hz Timeless to decently recorded/mastered songs. So, no listening to Burzum or any toilet-fi quality Black Metal with my 7Hz Timeless – unless I pair it with slightly less clinical sources that offered a bit of warm smoothness like the VE Odyssey HD ahahaha.

Speed & Transients. This is mandatory for me, no exceptions. 7Hz Timeless did not disappoint. The speed is nothing short of exemplary. Even with breakneck fast songs from “Snowstorm” by No Point in Living, classic Black Metal with intense guitar tremolos laced with equally nerve wrecking blast beat drumming exceeding 200 BPM, 7Hz handled them all without even blinking. With more civilized music, again taking Sinne Eeg and Diana Krall as examples, transients were handled deftly with great dexterity. Notes attack and exchanges seamlessly presented without any hint of congestion. 7Hz Timeless exhibited great competency equaling the speed of Etymotic Balanced Armatures.

Soundstage & Imaging. What can I say? I am floored with this 7Hz Timeless. The staging is wide, spacious and with great depth and height for a magnetic planar IEM. Such a stark contrast vs the narrow-ish TIN HiFi P1. At times the 7Hz even made my FOSTEX T40RP MK3 sounded confined in! But this largely depends on the prowess of the source and amplification. On my Sony Phone, there’s nothing to talk about, the soundstage is rather almost “meh”. However, it is a different story with the combo of TempoTec Sonata E44 feeding 4 Vrms of Line-In AUX to VE RAP5 amplifier and driving the 7Hz Timeless. The headstage offered headphone like experience with lots of air and sense of space. What remained consistent, spatial imaging is very holographic especially for song that are optimized for such listening experience. Power it right and there’s great soundstage awaiting.

Adaptability and Scalability. As has been mentioned repeatedly above, 7Hz Timeless is a very versatile IEM. Just by swapping the tips and the sound would behave differently. I haven’t even done any cable swaps. I am satisfied with the sonic characteristics of the stock cable, but perhaps sometime down the road I will be curious enough to explore that. On the subject of tips, I have included a photo describing the sonic differences as noted by my ears. For different person perhaps different shape, sizes and material offering completely different experience.


Scalability wise, 7Hz Timeless turned out to be a quite an efficient magnetic planar IEM, way more efficient than any other in this segment perhaps? (I know it is more efficient than P1). Sounds great straight out of my Sony Xperia Phone 3.5mm jack, considering that Sony Xperia has always been known to be on the weaker side of things when it comes to driving power, this is impressive.

Paired with Ovidius B1 and TempoTec Sonata E44, 7Hz Timeless really sing with exuberant dynamics and refined guile. Paired it with VE Odyssey HD, warm smooth Hi-Fidelity on the go in the most compact form factor. Paired it with a dedicated amp and my brain melted. Enough said.

EPILOGUE​

Well, if you have been reading this far, there’s no hiding how impressed I am with this 7Hertz Timeless. It exceeded my expectations and with the tune up I have done to my own unit, I can confidently say that it will take a LOT for me to consider upgrading to another Magnetic Planar unit, especially if their asking price is above $200.

7Hz Timeless officially replaces my longtime TIN HiFi P1 and quite possibly Etymotic ER4SR too. P1 while sounding great, took me a lot of tuning to get it sounding great – not forgetting the crazy tips rolling of over 20 pairs before finding the one that fitted to my taste and usage, the demand on power for it to sound decent, cable swaps etc. Yes, my P1 sounds great still, but it is a lot easier for 7Hz Timeless to achieve similar results and offered a bit more. In contrast the reasons that I will still use my P1 is when I want to indulge myself in organic, analogue, warmer presentation. It’s good to have choices.

7Hz Timeless is a very refined magnetic planar unit that has it all. Technical competencies, musical presentations, excellent scalability, ease of drivability and most importantly, a great value offering near TOTL sonic qualities that is hard to achieve by most magnetic planars in this form factor. I will actually use my 7Hz Timeless for my daily driver.


Tuning calibration done to match as close as possible to Shure KSE1500 characteristics

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!

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.

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:

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.

Here is the product purchase link: https://hifigo.com/products/7hz-timeless-14-2mm-planar-in-ear-earphone

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.



Source: Shanling M3X - balanced out/high gain

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.

Review Of The 7Hz Timeless​

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:-

*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.

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

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

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.



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!



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.

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.

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

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.

Intro​

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 ​

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 ​

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​

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.

Overall Grade: A

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.

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

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.

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

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

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!

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:
https://hifigo.com/products/7hz-timeless-14-2mm-planar-in-ear-earphone



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 .




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.



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.



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.



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.

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



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.

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.



ACCESSORIES-

1. Aluminum case
2. Wide assortment of silicone tips in good cases
3. MMCX cable
4. Documents and QC card

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.

MIDS-




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.



COMPARISON-

BQEYZ AUTUMN
Pros-
More balanced signature
Better mid bass tightness and definition
Better inter-instrumental separation
Texture is better enhanced
Better notes edge definition
More controlled and balanced notes
Wider stage
Good change in sound with filters

TRI I3 PRO-
Pros-
Better treble extension
Better treble details
Better sub-bass
Better stage depth and layering
Better transparency
Better mids
Note body definition was better.



TIN P1 PLUS-
Pros-
Better treble extension
Better air in the string instruments
Better transparency
Better edge defintion of the notes
Better texture in bass

TIMELESS 7HZ
Pros-
Bass is warmer
Sub-bass is warmer
Better vocals than T1 plus
Less air
Less details

MOONDROP KATO-
Pros-
Excellent dynamics
Excellent tonal accuracy
Beautiful airy notes and treble (less than p1plus)
Well extended in the treble region
Has sub-bass and is mid bass heavy
Beautiful separation and spacing around instruments
Wide stage
Excellent imaging and resolution.



SUMMARY-
If you are into the planar separation, stage height, treble and details , you are not going to like it much. But for those who want a good musical, smooth treble planar but small hint of planar transparency this is for you.

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

[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 .

Single Planar-based IEM…this is one niche bracket of IEMS…not too many options. You can count them on fingers:

1.Tinhifi P1.
2.Tinhifi P2
3.Audeze IEMs
4.Monoprice M300, M350
5.Toneking P10
6.Simphonio P10
7.Harmonicdyne P.D.1
8.Dethonray Tender 1

That’s it…

So now we have Timeless. The following review is an effort to assess where does Timeless stands. The unit has been provided by hifigo.com in return of my frank views on this IEM. You can get the same by clicking here.



Technical Specifications:

• Large 14.2mm Planar Driver.
• Ultra-Thin Diaphragm.
• Powerful Double-Sided Neodymium Magnet.
• A custom-developed high-quality cable.
• Standard MMCX connectors.
• Available in both 3.5mm/4.4mm termination options

Build and Fit:

7Hz Timeless has a full metal build, utilizing aviation-grade aluminum, which gives it a sturdy yet light feel. The bundled cable is a high-purity cable made with a combination of single-crystal copper and silver-plated single crystal copper cores.



The cable has an outer shielding with silver-foil wire for a warm sound. This cable has standard MMCX connectors. Users can choose between two different termination options while purchasing, 3.5mm SE or 4.4mm Balanced.



The Fit is exquisite, and you will not feel the weight of iem over a span of large listening hours despite them being of bigger shell size.

Sound Impressions:

Lows:

  )
• Cold Heart (PNAU Remix) By Elton John & Dua Lipa (
  )
• Chandralekha By A R Rahman (
  )
• Spirit Of Rangeela By A R Rahman (
  )

The Bass on Timeless has a sweetness to it. IT has both the quality and the quantity aligned to it. The texture the comes out when you play the first track will hook you to it and you will start the endless loop of the song. The mid-bass has an accuracy to it. The decay is swift and hard. The sub-bass is a bit lacking but the overall bass texture compensates for it.



Mids:

• Bombay Theme by A R Rahman (
  )
• Wo Khat Ke Purze Uda Raha Tha By Jagjit Singh (
  )
• Yeh Kya Jagah Hi Doston By Asha Bhosle (
  )
• Dikhai Diye Yun By Lata Mangeshkar (
  )
• Aye Dil-E-Nadan by Lata Mangeshkar (
  )

The mids are natural and magical with Timeless. The vocals are well-balanced as there is no bass-bleed observed. Although I noticed some peaks that was fixed by tips-rolling. Also, the unit was still not given the full burn-in period. The planar-timbre gives this item a bright feeling, although let me stress the fact that this is not a bright iem. But yes…the natural warmth will be missed. I would suggest using warm sources to compensate for this.

Highs:

• Aaromale By A R Rahman (
  )
• Sadda Haq by A R Rahman (
  )
• Naadan Parinde By A R Rahman (
  )
• In Your Eyes by Peter Gabriel (
  )

Highs have a very good presentation…full of details and dynamics. The highs have extensions so good that you will hit your playlist on repeat mode. For me, the tracks mentioned above are amongst the best few to experience the highs in a track. The details are to die for and this is possible because of that sweet planar-timber.



Soundstage:

The stage is wide enough to surprise you. It has a depth present as well. SO overall a near holographic feel is there. The complex tracks do not get cluttered. No notes are missed. No frequency overlaps. The more you feed power to this the more you get the stage and imaging.

Conclusion:

Timeless is a very necessary entry in the Single Planar-based iem. The ease to drive…the ease of fit…the ease of cable termination…This one does so many things right. If you want a planar-based iem, this should be in your consideration.
