Reecho & Peacock Audio Spring


Attractive, deserve the money it ask for
Pros: - Eyes catching design, build quality
- Wealthy accessory, nice packaging
- Comfortable, fit
- Solid, reasonable amount of bass
- Realistic, lifelike sound. No harshness or sibilant
Cons: - Not the most engaging earphone for everyone tastes
- A little more detail would be great
I'm not a professional reviewer or musican, i write this review like a music lover.
Gear: F. Audio Fa3s. Spring is sensitive with source, let it play good quality music and music player, a phone would not do it probably.


Stock cable is good build and sound quality. But personally i don't really like spc cable, it makes upper mid sound unature, especially male vocal. Therefore all my experience with this earphone, i used my pure copper cable.

- Burn in: Spring has 2 DD (one 8mm for low, 12mm full range ) and 1 BA for high. It did'nt take many hours for stable sound like i thought, just 2-3 hours. Sound from out of the box a little bit compressed.

- Fit/Isolation: Spring fit good in my ear, one of the most comfort iem i've tried. Isolation is average, so don't use Spring somewhere too loud. Stock tips looks nice but I used my familiar third party eartips.

- Overall sound: This earphone remind me about Whizzer A15 Pro(Haydn), very balance sound, not really emphase on any frequencies, realistic and lifelike timber. "Boring" was the word i heard the most when someone first tried A15 Pro or Spring.

- Bass: Bass has good speed, solid and tight, good control and not gonna bleeds into the mid. Mid and sub bass have medium impact, quantity, and deep. Work nice with acoustic bass, a liitle bit lacking impact and rumble on heavy electronic dance.

I listened "Kill this love - Blackpink" and "Fantastic Baby - Bigbang" for dance genre. 02:50 on "Kill this love" track, lack rumble on sub bass, and first 30s "Fantastic Baby" strong bassline, just a liitle bit more to satisfy my ears.

With lighter electronic bass like "Still Alive - Bigbang" or, acoustic bass in Miyuna's track 天上天下, Il Divo's songs, Spring did really amazing.

- Mid: I don't feel like "thin" on anywhere of midranges. i would say it is "Dynamic timber" i've heard the same quality in Whizzer Haydn. Very realistic, nature mid with enough detail that you can enjoy songs from the most genres. A little warm, not going to micro detail, sound good in both male or female vocals. Separation is nice also.

Kalafina's Seventh Heaven made me moved. like 3 of them in front of me. Il Divo - Tell That To My Heart and Bigbang - Blue are amazing CLEAR. I love Spring midrange so much.

- Treble: Not once sibilant found, even with the spc stock cable. But Spring can be describe like a bright earphone with stock cable. Change cable to pure copper made Spring sound balance, nice detail high, good energy. Spring emphasized a bit on the bass and treble but can't call this iem like a "V", because just small amount of boost.

Teayeon - Four Season felt nice in my ear with nice energy of treble without harshness. Le Couple - Saishuukai also made similar thing for me.

- Comparison: Whizzer Haydn has deeper bass, slower, less control. They all have clear mid and nice separation, average staging, good amount of treble energy.

Tinhifi P1 has more detail in midrange and treble. better speed bass. but lacking deep mid bass, weak sub bass.

- Conclusion: Reecho-Peacock Spring is amazing for my taste, i will keep this set forever :)) for both sound quality and the visual. Like i said, Spring not for everyone tastes because it's not engaging enough. Buyers - you will know what you need to choose Spring or not

Reecho & Peacock Spring Fever: 2DD & 1BA
Pros: Sound, cable, design, case.
Cons: Soft sounding and lack of aggression in some musical genres
The headphones are a collaboration of two Chinese brands: Reecho and Peacock. They are hybrid monitors consisting of a dual dynamic driver and one BRC30095 balanced armature.


Impedance: 16 Ohm
Frequency Response: 10 ~ 38KHz
Sensitivity: 106 + -3dB / mW
Distortion: <1%

The set includes two headphones, a 2-pin cable, a comfortable leather case and 13 pairs of ear pads made of different materials. The cost of the headphones is around $100-120.


The cases are made of glossy acrylic and have a very beautiful pattern. They fit comfortably in the ears, do not crush or fall out. The sound guide nozzle has a rim and is covered with a metal mesh. The cable is connected via a 2-pin connector. The silver-plated copper cable is quite thick and high quality. The plug is gold plated and straight. All fittings are made of metal and blend harmoniously with the headphones.


The headphones were listened to on the following devices: Colorfly C10 (mod), Colorfly C200, Hidizs AP80 Pro, Realme 5 Pro, Acer Swift 1 (Asio), Esynic q1.

The sound from the headphones is quite smooth and soft. The high frequencies are detailed, well developed, the mids are without dips and without undue aggression. The bass is not accentuated and sometimes lacks punch, although overall I have had no problem listening to electronic music or hip-hop. At the same time, my friends, after listening to these headphones, complained that they lacked bass. He is overly relaxed, lacking depth of work and impact. To me, the sound seemed not tiring and pleasant. But it all depends on the genres you listen to, your personal listening characteristics and preferences. The scene is average, detail is above average.

The Reecho and Peacock, Spring Day: a particular IEM for particular people.
Pros: Monitor-like sound, clear vocals, terrific transients, good imaging.
Cons: Overly dry sound signature, some mid-forward harshness, soundstage limitations.
Hi Everyone! Its Your Friendly Neighborhood Reviewer with InToit Reviews!
Welcome back to the Neighborhood!


Today we’re looking at, perhaps, the prettiest IEM to ever come through the channel: The Reecho and Peacock, Spring Day. What makes the “Spring” special is that it is a hand-painted IEM, and it also has a rather unique configuration, consisting of two dynamics and a single balanced armature. I particularly like the colorway of it- the swirl of blue and green, with hints of golden yellow is very striking!


With regard to fit and finish, the fit is very comfortable. The shell, which is also said to be hand-made, is of a nice size that is neither too large nor to small. The shape is ergonomic, and the stem is neither too long, wide, or shallow. There is a lip at the end of the stem to hold tips in place. Others have reported difficulties with the tips remaining secured to the stem, but I had no such difficulty with my set.


The difficulties with my set have to do with the cable and its connection to the IEM. While the 2-pin connector of the right IEM aligns at a 90-degree angle, the left connector’s 2-pin rests ajar; leaning to the left aggressively. While this might not seem like a big deal, it does affect how the left IEM rests in my left ear somewhat.


Additionally, while the look, fit, and finish of the cable itself is first class, it’s sound is not a good match for this IEM in particular. The cable that I chose was the silver and blue variant. With this cable, the Spring is overly aggressive in the mids, and can be sharp at times. I found a tripowin, zonie cable to be a better match for the Spring, as it produced much more even sonics. A brown, copper cable exists as an alternative option for the Spring, and while it may not look as pretty as the blue variant, it might sound better?

The Spring also comes a nice, brown, leather carrying case, a small carabiner, and a variety of assorted tips. While I found all variety of tips to be rather nice, the included clear silicone tips with the black bore sounded the most balanced and liquid for the Spring. In my opinion, they were the warmest, and best tonal match for this set.


Tip selection was particularly important with the Spring, as its signature changed greatly with tip selection, and, in general, its tonality lacked warmth and leaned towards a drier, more airy quality. These sound like Italian Pinot Grigio tastes.

Dat’ bass though... The bass is exceedingly well executed, and exceptional. With sufficient volume, this is one of the most appropriately dynamic IEMs that I have ever heard. Its dual dynamic set up more than likely contributes to this particular character. The mid-bass is punchy and its most present in the range, but there is also a perfect amount of sub-bass that lurks beneath the surface. Overall, although I can be emphasized at times, the bass is extremely natural sounding in my book.


Like the bass, there is also some upper mid-range forwardness and treble intensity that lurks in the grass and presents itself harshly on some recordings as well. These can test my limits with regard to both its highs, and its mids. Most of the time mid-range and treble presences are tolerable, but they do sound peaky to my ear on particular tracks, even if they do not really graph as such. I think that the highest peak at 2K and the additional elevation at 5K are what draw my attention mostly- although neither appears like it would be significantly elevated on a graph.

Forwardness in the mid-range was particularly evident on certain sources, as I found the Spring Day to be extremely source dependent. It simply did not sound good on overly stark devices. As a result, sources such as the THX AAA 789 were not a good fit for this earphone. The FiiO BTR 3K and the Gold Note DS-10 Plus were my favorite sources for the Spring Day. Each has their own mild flavors of warmth which were lent to the Peacocks most favorably.


In my listening, the soundstage on the Spring wasn’t particularly wide, but it did have some good height and a decent depth of field to it- despite other obvious limitations. One such limitation occurred with regard to the Springs limited sense of expansiveness, which seemed perpetually held bac, in its scope, by the restricted width of the sound field. Having said that, transients were notably terrific. Imaging was also accurate, and, notably, above average, while the auditory plane appeared rather flat as one would expect. Layering capabilities were enjoyable within the space it created, but separation, which, although sufficient on most music, did suffer on busier tracks, and sonics did appear to become jumbled with increasing musical complexity.

In contrast, vocal clarity and articulation was quite impressive. Although only mildly forward in nature, the Spring’s vocals were exceptionally precise, well separated, still appeared isolated from the rest of the mix. If you ever wanted to know exactly what an artist is saying on a particular track, this would be set to listen to it on, in order to figure it out.


Which brings me to my last point on the Spring. Others have claimed that the Spring presents a monitor-like sound, and outside of its mild aggression in the mids, I’d have to agree. For the most part, these did deliver sonics that were mostly monitor-like, but they were also true to the recording; for the better, or for the worse, that interpretation would be up to you. Like most other monitors I have auditioned, details were present and well articulated; however, general resolution was only good for the price, but not class-leading; and the Spring's dry, brisk, and airy presentation lent itself to some murkiness at times.

In the end, I do not want to sugarcoat it. There are some significant compromises to be found here; from the Spring’s limited sound-stage, to its tonality challenges and somewhat mid-forward nature, the Spring did leave me yearning for some additional musicality, in the end. Having said that, it is not a bad IEM by any imagination. It is mostly comfortable to wear, and it comes with a nice accessory package; even if I did not like the acoustics of the included cable variant that I selected, and I would ultimately recommend against it. Still, from a sound perspective, part of me almost regrets purchasing these, but they, nevertheless, image well, have terrific transients, and have a magically, dynamic low-end, which just sounds right to my ear. The vocal presentation is also executed exceedingly well to boot, and it is nice to have a monitor IEM in the collection. Those who prioritize vocals, a unique low-end, and a monitor-like sound may want to take note of the Reecho and Peacock Spring Day, even despite some of its aforementioned misgivings or other draw-backs to consider.

Bought in December 2012 from Linsoul. I didn't use them for the first 9 months or so as I had issues with fit and them not being very comfortable. Turns out I wasn't quite putting them right in my ear. Once I figured that out, they were more comfortable, but not perfect and I started using them more.

The IEMs were stored in a small tupperware plastic container when in my bag.

Unfortunately, after around 5 months or so of usage, I went to get them out and the shell on One of the bodies just broken apart. Very disappointing and very poor build quality. These units were treated with loving care and were NEVER roughly treated. They weren't even heavily used, probably being used twice a week over the 5 months period, for like 1-2 hours each listening session, tops.
I reached out to Linsoul, but their attitude was poor and I was pretty much told tough luck. I guess I won't be buying anything from Linsoul ever again. Yes, they were out of warranty by a few months, but I mean, what about good will?

I can't find any information on how to contact the actual manufacturer of the product and complain, so I will leave it at that.

I will go back to my CCA C10 units which were used much more heavily, for a longer period of time, and had zero issues (so far). And were a third of the price.

One very unhappy customer.

Reecho x Peacock Spring Fever (really fever)
Pros: a lot of distant highs, good lows
Cons: a lack of lower mids and lower highs, so musical instruments doesn't have any weight or fat
Hello! Today I will share my opinion about the Reecho x Peacock Spring Fever, which can be found here.
So let's get started.


Low frequencies.
Subbass is not enough in relation to dynamic models, midbass is emphasized a little better. The bass is fast, quite percussive and biting, sometimes it can surprise with elasticity. Overall, the bass is very pleasant and the electronics in the headphones sound great.


Medium frequencies.
And this is where the fun begins. There is almost no lower middle. I have never heard such a dry sound. I've heard different V-shaped headphones, but this is the first time I've heard this. If you want to take an electronic track or classical music apart, then the lack of a lower middle can be beneficial. If you listen to rock or metal, then more on that later.
Further, up to the top of the middle frequencies, everything is very good, rich, detailed. The vocals are close to the listener, the presence zone is raised up and this gives extra air to the stage and some additional detail if you need it.

High frequencies.
And again the fun. There is no lower part of the high frequencies either. Nearly. The cymbals don't have any weight, but that's only part of the picture.
There are a lot of distant high frequencies. Lots of. And if you listen to beautiful classical music, where you need to listen to cymbals, a triangle, then you will like the sound. However, if you listen to metal, rock and other heavy genres, then these long-range highs will just be everywhere they can. Instead of Architects - Doomsday, you will only listen to hiss and cymbal puffs.

The scene is shallower than average in depth and wider than average in width. In general, the positioning is good and accurate. Not the most accurate I've heard, but if the treble in the track is not accentuated, then the scene is legible.


What do we end up with? If you are a bodybuilder preparing to perform on stage and need to reduce your body fat to 3%, then these fat-free headphones are for you! When listening to metal, it feels like the muscles are being pulled away from the tendons and bones due to dehydration. These headphones are definitely not for everyone, but they may find their listener.
Thanks to all!

Reecho x Peacock Audio Triple Driver Spring Fever.
Pros: rich set, beautiful appearance, light weight, comfortable fit, high-quality cable
Cons: you need a suitable source, not for all genres of music.

Configuration and appearance.
The set includes a decent-sized case made of brown leatherette with a zipper.
A set of various ear pads on the substrate.
Good quality cable with connectors and divider made of metal.
Earphones with a pattern that resembles a peacock's tail. The headphone cases are light, small in size, and fit perfectly in the ears.
photo_2020-09-07_15-41-50 (2).jpg


After listening to the headphones for quite a long time, there is no specific opinion about them, it seems that there is nothing to find fault with and at the same time nothing caught on.
They sound rather flat and boring, lack mass at low frequencies, emotions at medium frequencies.
High frequencies do not have a good length.
Pretty mediocre resolution.
At the same time, there are no sibilants, the so-called "saw".
photo_2020-09-07_15-41-48 (4).jpg

Headphones are probably suitable for slow, quiet music, with a small number of instruments.
The sound is smooth and dry.
I think they need a source "fatter" and with good power to at least breathe some life into them.
Light in weight and sound like a peacock's feather.

Driver Setup
: 2 Dynamic Driver + 1 Balanced Armature Hybrid

Price: SG$180-190


Disclaimer: I purchased this IEM from DD Audio on Aliexpress at a slight discount and this review is written of my own accord.

The moment I laid my eyes on these earphones, I knew I had to at least try them. It has an interesting driver set up of 2 dynamic drivers and 1 balanced armature. It almost looks like sibling of the Thieaudio Legacy 3 which goes for almost the same price and you could expect to see some “sibling rivalry” in this review.

Packaging and Accessories (Score: 9.5/10)

You can tell they really went all out to impress right from the unboxing. It comes in a brightly coloured box which matches the overall colour scheme of the IEMs. Opening the box would reveal a large pleather case like the one you would get with the Thieaudio Legacy 3. The only negative thing I experienced in the whole unboxing was some black glue residue stuck to my IEMs and I spent quite a while trying to get all of it off.

I chose the “Bright Moon” design for the cable that comes with the IEMs and they look much prettier in real life than in pictures. The 8-wire cable is braided very beautifully, and both the audio jack and Y-split are made of a sleek brushed aluminium.

The IEM also comes with a whole variety selection of tips which you may need as I find the sound changes quite significantly with tips. I prefer silicone tips and just used my SpinFits which fit comfortably for me.

Build Quality and Fit (Score: 9/10)

Build quality is nothing short of amazing. I think Peacock Audio have already set a precedent and made a name for themselves in this area with their previous release of the Peacock Audio P1. The IEM faceplate design really looks like a Peacock feather pattern and the colour scheme really sticks with that “spring” vibe.

IEMs are quite small for the “Custom-like” design, similar to the size of the Legacy 3s. However, the Springs are possibly the most comfortable earphones I have owned to date. Once they are inserted, they stay there and feel almost weightless in the ear.
The only problem I faced here was the 2-pin female connection on the IEMs. They were very tight, and I had to use significant force to insert my cables and it was anxiety-inducing.

Sound (Overall Score: 8/10)

Sources Used

  • Fiio Q1 MkII
  • Shanling M3s
  • Schiit Stack (Modi & Vali) (I had the best experience using this set up, I’m not sure if it has to do with the Springs performing better when better driven or just it being source dependant)
Albums and Tracks Listened to
  • Andy Gibb - The Very Best Of
  • Lion King’s Original Soundtrack
  • Randy Travis
  • Spinners - Essentials
  • Randy Travis’s Forever and Ever, Amen
  • Mozart Clarinet Concerto In A Major, K.622 by Martin Frost
Bass (Score: 7.5/10)

The bass is clean and tight. It isn’t the most powerful but does extend low and possesses good punch and rumble. On the Spinners’ “Cupid/I’ve Loved You for a Long Time” and Andy Gibb’s “Shadow Dancing”, the bass line remained clear and articulate throughout. The problem I have is that the upper bass sometimes feel a little weak and it doesn’t provide for a smooth transition into the mids. In Lion King’s “Be Prepared”, I would usually listen out for the bassoon notes and they don’t sound as satisfying on the Spring. It’s there but it doesn’t have the full texture and flavor that I love so much from the lower register of the bassoon.

Mids (Score: 8/10)

Mids is a bit of a mixed bag for me. I’ll start with the negatives. In many instances, I was left wishing more from the lower mids. They lacked the full-bodied feeling and caused certain male vocal tracks to not feel well supported. Voices like Randy Travis in “Forever and Ever, Amen” sound smooth but could use more richness and body. However, I tried an experiment by listening to the Springs on my Schiit Modi into Schiit Vali, and it remedied this problem quite significantly most likely due to the warmth of the tube amp sound.

As the vocals move up in pitch and frequency, they start to become more impressive. Higher pitched vocals are really engaging on the Springs.

Certain instruments just make me go wow on the Springs. Clarinet, Oboe and Flute solos really serenade with a certain je ne sais quoi. It hits the sweet spot where it isn’t too glaring and not too laid back either.

Treble (Score: 8.5/10)

The treble picks up from where the upper mids and continues the elegance. Micro details are well preserved, and it perfectly captures the sparkle in most tracks and carefully avoids sibilance. Crash cymbals and hi-hats all come out crispy clean and the Spring just seems to be in control always regardless what you throw at it. It’s very transparent which also means if you have poorly recorded tracks it’ll really show on the Springs. It helps keep tracks exciting without being fatiguing (for me personally).


I had some issues with the tonality of the drumset at times. The ride cymbal, toms and kick drums have a certain unnaturalness to their sound in some tracks. This possibly stems from the problem with the body in the lower mids.

Soundstage and imaging are great, making this enjoyable especially when listening to wind symphonies and string orchestras.


Something important to note is that the Springs are source and tip dependent. If something doesn’t feel right immediately on your set, give it a chance and do some experimenting. I would say it seems like people who tuned it had a specific sound they was aiming for, and the Spring has done a very good job in excelling where it's meant to. It presents details well and manages to be analytical without sounding cold or harsh, something I really enjoyed. However, it does struggle in achieving naturalness and body in the mids sometimes.


Thieaudio Legacy 3 vs. Reecho & Peacock Audio Spring


The comparison between the two had to be made, with both being such standout performers at almost the same price with similar form factors.

Comfort wise, I personally find that the Springs were a better fit for me, and the cable connector was more fitting over my ears too. If packaging and accessories matter a big deal to you, the winner would definitely be the Springs and it made me wish the Legacy 3 could match the unboxing experience of the Springs.

In the first few hours, I was very sure the Springs were nowhere near as good as the Legacy 3s. However, after the next few days of listening and getting used to the Springs, I felt that it has its own areas where it shines. Hence, rather than being so sure the Legacy 3 was a big step up from the Springs, they both seemed to complement each other.

Objectively, I would say if I had to choose between the two, it would still be the Legacy 3 as it is much more versatile, and I prefer the musical and mature tuning and tonality of the Legacy 3. The bass on the Legacy 3 is hands down better than the Springs, even though I would say the bass on Springs is very much satisfactory. The mids although not as forward as the Springs but are more musical and work for a greater spread of music. However, the times when I wished the Legacy 3 could be a little more engaging with the upper mids and treble, the Springs delivered.

These are my opinions on the two based on my musical tastes. Both are outstanding performers at their price, but the Legacy just does more things right and tips the scale in its favour for me. The Springs do have their niche and there are times that I enjoy the Springs more. However, as an indicator, those who prefer their treble a little more tame would more likely prefer the Legacy 3s. I spent a long time (and had a hard time) comparing these two sets and if you have any questions or would like me to help you test anything please feel free to let me know, I’d be happy to help.



I would see this making into the list of IEMs I keep around for a long time, especially one of those I bring on my daily commutes given how well it isolates and fits in my ear without any discomfort.

However, its versatility and ability to perform right out of the box without any fiddling sets it back slightly. It does sound very technically capable and has been tuned very well, and I was really thankful it didn’t disappoint for something that looks so stunning.

The standout feature of the tuning is the presentation of female vocal tracks, instruments and treble. All this is done with a very natural and clean and tight bass presentation. It keeps the image of the season of “Spring” with its bright tuning but never comes across as harsh. From its sound to its looks, the Spring is an absolute beauty.
Do you think changing cable (Pure copper one) would improve bass and lower mid?


New Head-Fier
smells like spring
Pros: tight bass and very wide stage
crisp mids and exciting highs
superb comfort
clear, tidy and open signature...
Cons: ... maybe a little too bright for some
might have a little more body in the mids.
who likes it warm and soft is not at home here
Rating: 8.6
Sound: 8.5

It's vernal. Colourful meadows, bright birdsong and virgin forests...
The SPRING by REECHO in cooperation with PEACOCK AUDIO should be associated with this.
Well, it presents itself already colorful and the sound is also a bit refreshing. Responsible for this are 2 dynamic and one balanced armature driver. The configuration has been somewhat forgotten and would have been expected the other way around. Two or three years ago it was the latest thing with the BQEYZ KB1. But the SPRING has little in common with them in terms of sound, and to be honest, I wouldn't have thought of a dual dynamic driver, but rather of two BAs.


For a good 120 €, the packaging and its contents clearly compete with far more expensive products. I don't really care about this and prefer a simple design and only essential supplements for a lower price, but unpacking the SPRING is really fun.

It is similar to a custom IEM in its construction and is also very small and compact. It is very comfortable to wear and with the included tip selection there are no excuses for not getting a proper fit and seal. It was not enough for spinfits, but 2 pairs of foamtips and 3 different types of silicone tips in different sizes offer a really big choice.
Plus a great 8-core 2-pin cable, which is available in silver and bronze/black.
The whole thing is garnished with a leatherette hardcover case with ample space, cable help and snap hook. CHI-FI heart, what more do you want.

Each SPRING is unique in colour. Mix springlike colours (yellow, blue, green etc.) and you get a colourful composition, which reminds of creative batik shirts or peacock feathers. Pretty and appropriate to the theme, but not for someone who likes it a bit simpler.


It would be silly to write that the SPRING sounds like spring, but the sound still has something refreshing about it. Very clear and rather bright, with a solid bass foundation and large stage.

With two dynamic drivers, which probably take care of the bass and the mids, I would actually have expected a bit more rumbling and more quantity. But this is not so. The bass has a pleasant depth, but without developing a particularly high pressure, is punchy and tight, as well as textured and quick on the move. Rather an untypical dynamic bass, although it does have an appealing dynamic. In addition, it remains very well-behaved in the midrange and the signature looks rather tidy and fresh, decently warm and oppressive. For me, the bass is allowed to bring even more volume and kick and to act even more from the deep, but it does what it's supposed to do and that in an extraordinary quality, on which the SPRING puts more emphasis than on quantity.

The mids are crisp and bring a pleasing energy without ever becoming harsh or unpleasant. I would describe the SPRING as quite balanced, with a slight focus on the upper mids and highs, which makes the SPRING sound quite bright, but without slipping into the unnatural. Voices are brought into the foreground, but without jumping into the face. That's the way I like it. The separation of the instruments is excellent and details can be seen in abundance.

One could easily guess from the signature of the SPRING that the Sibilant will become an issue. No, not at all, the area is elegantly curved without any loss of resolution and playability. But the SPRING can't do without it either. Likewise, it can sometimes get a bit tinny in the high frequencies and cymbals stick out too much, which is sometimes a bit exhausting if you get these frequencies too much on your nose. Here the wheat is quickly separated from the chaff when it comes to recording quality and mixing. Airy, detailed highs, which in rare cases can be too good to be true, and therefore do not act completely fatigue-free.

All in all I prefer a little warmer and softer. However, I like the tight bass and the crispy mids, especially in rock or acoustic tracks. Voices sound very round and natural. A bit more body would be good, but you can't describe the SPRING as thin-skinned.
Remarkable is the stage and separation of the SPRING.


Even though there is of course a lot of marketing in the SPRING, I take the sound of spring away from the SPRING. Not too cold, not too warm, clear and direct and with a "colourful" abundance of details.
I can well imagine that there will be other models that correspond to the seasons and I am curious to see how they will sound, even if I already have a rough idea. Until then, you can enjoy the spring-time... eh SPRING. Really a successful IEM.

@LostnAmerica Thanks for your detailed report. :)

Spring and Spring Fever are the same in-ears in every case. I think it's all about if and who can interpret the chinese characters on the packaging. Normally you start with the number of dynamic drivers, followed by the BA drivers, or whatever. In this case the package says 2 + 1, but I can't say it with absolute certainty, because as I wrote in the review, I would have expected one dynamic and two BA drivers on the first listen.

Looks like this is an interesting model to try after sometimes with my LZ A6. I think copper cable will help warm up the sound, add a little thickness on the bass and mid. And my F.Audio Fa3s - a warm, musical source will help out too (it has some signs of tube amp). All 3 reviews above really nice. Thanks
working on my review this weekend; might post it here when I'm done.
