Overview

The details behind 7HZ Timeless II.

The 7Hz Timeless II upgrades the original with a 14.5mm planar magnetic driver, featuring the world’s first dual-sided coated diaphragm for enhanced responsiveness. It also introduces a tunable nozzle system, allowing users to adjust sound with different nozzle options. The redesigned 7-layer driver enclosure ensures precise tuning, durability, and stability.

Highlights

  1. Upgraded 14.5mm Planar Magnetic Driver

    Building on the success of the original Timeless, the Timeless II introduces an upgraded 14.5mm planar diaphragm—the first dual-sided coated diaphragm in an IEM. Using a specialized silver alloy coating and driven by a powerful dual-sided N52 magnet array, this new diaphragm delivers exceptional responsiveness, pushing planar technology to new heights. 

  2. Tunable Nozzle Design

    The Timeless II features a tunable nozzle system, inspired by speaker phase plugs, allowing users to adjust ultra-high frequencies to their preference. Different nozzle options provided to offer precise sound adjustments to suit any music library.

  3. Redesigned Driver Enclosure

    The new planar drivers are housed in a 7-layer acoustic enclosure with double rear venting and a secure locking system, ensuring balanced, natural tuning. The diaphragm is directly mounted for increased rigidity, stability, and tighter surface tension.

  4. Upgraded Detachable Cable

    Equipped with a 4-core ultra-pure 7N single-crystal copper cable and 0.78mm 2-pin connectors, the Timeless II offers enhanced warmth, body, and detail. The detachable cable design allows for easy customization and extended durability.

7HZ

The 7Hz Legacy

7Hz made a global wave in the past with several of its most popular models. IEMs such as the Salnotes Zero, Dioko, and Timeless gathered massive popularity due to their amazing sound-to-value performance. 7Hz has proven itself to the worldwide audience as a trusted manufacturer of high-performance IEMs, and will continue its legacy with better innovations and stronger community engagement. 

7HZ Timeless II
Upgraded 14.5mm Planar Magnetic Driver

Upgraded 14.5mm Planar Magnetic Driver

The original Timeless was one of the benchmark planar driver IEMs when the concept was first started. Since then, we have had much time to re-examine the planar magnetic driver, and innovate more efficient designs. The Timeless II features the latest R&D from our team, with a bigger 14.5mm diaphragm. This new 14.5mm planar diaphragm is the world’s first dual-sided coated diaphragm to be used in the IEM platform. Our in-house coating process layers microns-thick even surface application of specialized silver alloy, which significantly increases the surface tension of the diaphragm. The new diaphragm, which is driven by a strong dual-sided N52 magnet array, is extremely responsive, taking the planar diaphragm concept to a whole new level.

Tunable Nozzle

Tunable Nozzle

The Timeless II also features a new tunable nozzle concept, so that the user can adjust their sound preference. This idea is derived from the concept of speaker phase plugs, which allows the extension and adjustment of ultra-high frequencies. We have designed special nozzle shapes, with different materials for precise tuning of the IEM. The different nozzles all provide unique and effective ways to adjust the Timeless II's sound to fit your music library.

Newly Designed Driver Enclosure

Newly Designed Driver Enclosure

The Timeless II’s new planar drivers required a redesign of the acoustic driver enclosure to provide a balanced and natural tuning. With a 7-layer design featuring a double acoustic rear venting system and a more secure locking system, the driver can be more precisely tuned, as well as be more durable and stable. The diaphragm was also directly mounted onto its support structures to provide more rigidity and tighter surface tension within the driver. 

Updated Cable

Updated Cable

The Timeless II comes standard with our new upgraded cable. The cable is a 4-core ultra pure 7N single-crystal copper cable, with detachable 0.78mm 2-pin connectors. This configuration was specifically chosen to provide additional body and warmth to the Timeless II’s new driver, while enhancing the transparency and details. With the detachable cable design, the user can change the cable to fit their preference, as well as extend the longevity of their IEM.

Planar IEM praised for excellent sound quality with detailed treble, punchy bass, and clean midrange. Customers said it offers "effortless detail retrieval" and "near-flawless tonal balance." Multiple reviews note quality control issues with nozzles, connector breakage, and channel imbalance. Best suited for electronic music; some found it less ideal for metal.

Timeless II is simply one of the best-sounding IEMs I have heard at any price.

Its effortless detail retrieval, paired with near-flawless tonal balance, allows every genre to sound natural, engaging, and complete. Add tactile yet controlled bass and a soundstage that expands convincingly in all dimensions, and the result is a listening experience that feels genuinely blissful.

Superb headphones at a great price with a little quality control problem (scratched case)

I've been planning to get the original 7Hz Timeless and later the AE version for over a year, but they are constantly not accessible in my country via local distribution. Finally I've decided to get them through Linsoul shop and I'm super impressed. The IEMs are made to the top standard and sound amazing. Quite more bassy than I've expected, but not in a bad way. The bass is very punchy in transients but soft and pillow-like in tonality. The highs are crisp and very detailed. I wish the mids were a little bit more forward and exposed, but it's my preference (and will be easily corrected with minor eq).
I'm really impressed with surprisingly heavy and nice, full metal case. The cable is nice, but too still for my taste (I believe in Tripowin Zonie supremacy).
Only downside that I've found is that the case arrived scratched in multiple placed along top of the lid. It's barely visible but easily noticeable by touch, which degrades the experience a little bit, especially at this price. I'm attaching a picture as a reference.

Sounds great but quality is questionable

Sound is perfect 10/10 but it looks like there is no QC for nozzles. Both flat nozzles look Ideal so that's good, but domed nozzles... oh boy. Silver nozzle does not looks perfect but I'd say it's acceptable. But golden domed nozzle is a complete trash, machining done on this is terrible, just look at the picture.
1. Pinhole from the top is not centered.
2. One of Gold nozzles has burrs left on both sides.
3. There are 4 holes and all of them are different size.
Cost is way to high for such quality accessories to be justifieble.

Critica A.(. (Madrid, ES)
A minor renovation but still great.

While the Timeless Original was already interesting, this IEM improves on aspects such as dynamics, timbre, and depth.
Added to the quality already present with the previous product, this 7Hz Timeless II is a great option for this price. I'm not mistaken when I say it's generally superior to the Aether, Timeless AE, S12 Pro, and so on.

7Hz Timeless 2 is an improved version of the legendary model!

The character of the sound is bright, clean, detailed, with a well-presented sub-bass.
The headphones have a bias towards the upper key.
Headphones like more power, and it is with a powerful source, even if it is budgetary, that they are able to open up and show the scale and filling of the scene.
I used different dac amplifiers and a couple of audio players and came to the conclusion that soft music sources or devices with a neutral pitch would be more suitable for Timeless 2.
Exclude sources with technical sound.

Initially, the vocals attract attention, they have high resolution and clarity of diction.
The performer stands out significantly against the background of the arrangement, the backing vocals are also well emphasized.
The voices of the performers are really lively, the smallest nuances are readable.
The vocals are clear to the point of transparency, as if floating in the air.
Whistling and hissing sounds are highlighted, but do not turn into sibilants.
The stage is quite wide, cone-shaped or trapezoidal, depending on the source.
As the power increases, the atmosphere in the scene fills up, becoming more dense and lively.
The listener is located in the first third of the hall.

The upper frequencies have a silvery color, they are more prone to a cold shade of sound.
There is an emphasis in the area of 8 and after 12 kHz, so the tops are detailed and abundant.
They may seem a little thin at some points, but they sound beautiful.
The percussion and cymbals of the drum kit are heard crumbly-separately, with the presence of the necessary granularity.

The midrange range is very similar to the Simgot ET142
The same impeccable presentation of live acoustic instruments.
An excellent acoustic guitar and an incredibly lively and realistic saxophone.
I would like to add a little physicality to the piano.
Electric guitars on effects are textured and aggressive, as they should be.

Low frequencies, namely sub-bass, deserve special praise.
The infrasound digs deep enough, becoming intelligible already at 20 hz, and specifically declares itself from 25 hz.
It has a pronounced texture and fills the scene with volume.
I want a little more mid-bass to add density to the sound, since the shift in tonality to the upper part of the range concentrates attention on itself.
Nevertheless, the bottom is quite enough and it is really good.
Metal sounds massive, with powerful low-frequency support.
Orchestral works also surprise with the massiveness of the big drum, the sound of which is perceived as rolling thunderclaps.

I recommend 7Hz Timeless II for metal (except classical heavy/hard), any electronics, orchestra, vocal works, folk rock, jazz.
Headphones with a clear, juicy pitch, aimed at fans of bright sound.
They will make great friends with musical, warm and neutral sources.
It's a good model that you can safely add to your collection.

Excellent planar headphones

The 7Hz Timeless II sound very good to me. I am not a specialist, but I own 5+ sets of IEMs and 3 over-ear sets too. The Timeless II are my only single driver set of iems, and those are one of the best sounding earphones I have listened to. They pair nice and are easy to drive with all my dac/amps, but my favorite pair is with the Cayin RU7. I listen to them with an upgraded UP-OCC cable from Hisenior.Flawless transaction, thank you Linsoul!

Good sound, but with some quality issues

I love this set. Good rumbly bass with awesome treble, but it's definitely not for people who like meaty or warm sound.

Main problem I have is channel imbalance and clicking sound in left channel when inserting the IEM. Additionally, the 3.5mm interchangeable connector broke after some use (it started skipping when the cable is moved), 4.4mm is still good tho.

Also, nozzles other from gold flower wouldn't screw into the left IEM. I prefer this nozzle, so it's not an issue for me.

Very nice

These are my first high quality earphones of such type, and I quite like the quality of the package, the earphones themselves and the sound. Albeit I must say, they sound much better with electronic music than metal. For me, the metal parts lack details and mid-range bass (as compared with full headphones).

The legend is back with new superpowers

The original timeless were some of my first serious iem's. These improve on those in every regards. Definitely worth the wait and the money $$$

find the timeless AE instead

missing the detail and soundstage that the original had. the different nozzles can play around with it some, but ultimately it's still little trade-offs in the eq that fall short. the timeless AE by comparison is more detailed, wider soundstaged, fuller with more forward mids, and louder despite both being around 15ohms. sub bass is bumped higher than the original, that's about it.
on its own merit without comparing it to it's brothers, id say it's totally fine, but definitely not at the price point. i wouldn't pay more than 100 for them. kinda like the eternal, i really wanted to like them, and tried so hard to find the niche or magic combination but they just fall short. such a shame too because they look incredible.

Nozzles?

My Timeless II included a total of four sets of nozzles. There were no instructions or information included in the package. What is the point of all the nozzles and the use case for each?

The cable is bulky, and I'm not a fan of 2-pin connectors.

The sound is good, but I can't tell if they're better then the Timeless in this regard.
