New Head-Fier
A Gem Let Down By QDC QC
Pros: Warm & Detailed Sound
Very Comfortable
Cons: Fragile QDC Connectors
Sisyphean Replacement Process
The Voyager 3, or as I like to call them-the V3 sounds excellent. its has a good stage, accurate details, & a warm low end that has a good punch but never overwhelms. A very enjoyable IEM for listening to complex music, you will really be able to take in every detail.

So why not a 5 star? I mean they sound great right?
Why not more detail about the sound & comfort of the shells- that was awfully brief.
Well, the thing is those details aren’t that important because I’m going to tell you to not to buy them.

Here’s why, there are two issues. The first is something other reviewers have mentioned, the QDC connectors are terrible. They are extremely fragile & prone to breakage. This is not good, but wouldn’t normally be a deal breaker. After all most companies are good with replacements.

However, most companies are not Linsoul Audio. The replacement process with this company is the single worst customer-service experience I have ever had. You will be asked for information you have already provided multiple times, you will be promised things will be sent out ‘this week’ but weeks later nothing will have happened, & you will be sent packages with only an apartment number & a post code- that of course do not arrive. It will take months, & there will be no progress & you will still not have a replacement item.

So, I can hardly recommend this item considering that there is a high chance your QDC connectors will have issues, & you will have to deal with the worst customer service team known to man, women or child. I regret not doing more research about this company on head-fi & other websites- but hopefully my warning can do some good.

I have also posted this review to Linsouls site, however there is a good chance they may delete it. If that does happen, I will update this review accordingly.

Thieaudio Voyager 3 and Legacy 3 Dual Review
Pros: Tuning switches
Awesome cable
Cons: Middling technical ability
Tuning ranges from decent to not great
Not competitive at its price point

This a dual review for the Thieaudio Voyager and Legacy 3. The Voyager 3 costs $160 and is a 3 BA IEM while the Legacy 3 is a 2 BA 1 DD hybrid that costs $120. Disclaimer: I received both the Voyager and Legacy 3 from Linsoul in exchange for this honest review. I have not been or will be compensated in any other way. Also, this review is effectively identical to my Legacy 3 review on Head-Fi, with just the order of presentation flipped around.

For those unfamiliar with the Thieaudio brand, they're a ChiFi IEM brand with a number of products at common price segments, with the Voyager and Legacy 3 being their entry-level products. More recently, they've made waves with the release of the Thieaudio Monarch and Clairvoyance, two ~$700 IEMs that genuinely challenge some of the very best on the market. What's interesting about Thieaudio is that they're actually the in-house brand for Linsoul; you likely won't find them on some of the other common ChiFi stores like those on Aliexpress (e.g. NiceHCK) or Penon Audio. Notably, the Voyager and Legacy 3 are some of the only IEMs in the <$200 range that feature dip switches for tuning.


What's in the Box?

The Voyager and Legacy 3 ship in a minimalist green box featuring its logo. You pull a green loop to slide out the inner box that presents IEM shells and a faux-leather carrying case. Inside the carrying case you'll find the 2-pin QDC style, over-ear IEM cable, a standard set of S, M, and L tips, and a SIM card ejector tool you can use to adjust the switches on the IEM shell. Between the two, I like the Legacy 3's shell design more. The gold clockwork faceplate is striking against the translucent light blue shell. It also has more customization options for the faceplate and you can even get it in custom form for not too much more depending on the customization, making it quite an attractive CIEM option for <$200.

The fit on both the Voyager and Legacy 3 are quite similar, with the typical ergonomic shape that's becoming increasingly common with resin shells. The Voyager 3 however is slightly bulkier than the Legacy 3. Both isolate fairly well. I find that the Legacy 3 does have some driver flex with its DD, marking a slight inconvenience when walking around at times. The cables these IEMs ship with are great. The Voyager 3 in particular ships with the Tripowin C8 cable and one of the best stock cables to come with an IEM that I've encountered. There's next to no cable noise, no cable memory, and is soft and pliable. The Legacy 3's cable isn't up to the same level but still beats out the vast majority of stock cables and is a bit rubbery. Needless to say, there's little need to cable swap unless they die for some reason.


As mentioned before, both the Thieaudio Voyager 3 and Legacy 3 each feature two dip switches for a total of four possible tunings. For the Legacy 3, the switches have essentially no effect and I won't make a distinction between them for this review. For the Voyager 3, the switches have a noticeable difference. I'll post measurements at the end of each review. For reference, I refer to the four tuning options as 00, 10, 01, and 11 where 0 refers to the switch in the up position and 1 in the down position. The settings are read left to right i.e. ON then KE. This picture provides an example of the 10 position.


Don't ask me what ON or KE stand for. I'll chalk it up to some odd lost-in-translation problem from the manufacturers.

Voyager 3:


Technical Ability: The technical performance of the Voyager 3 is quite similar to that of the Legacy 3. Both imaging and soundstage are about on par for most IEMs - a flat 2D, in-your-head sound. Resolution and separation are very middling and a step back from the Legacy 3. Dynamics are blunted. For $160, I'm fairly disappointed. The technical performance of the Voyager 3 is on the level of some of the better $50-80 IEMs. BA timbre is not bad but is absolutely noticeable in the bass when comparing to the Legacy 3.

Tuning 00: This is my second favorite tuning. The bass is bloated but there is serviceable upper mids clarity to balance things out. There's a peak around the lower-mid treble that manifests as splashy cymbals and brings out the crack of the snare. Some may find this fatiguing. As with the other tunings, upper treble is lacking and there is no sense of air or sparkle.


Tuning 10: This is my favorite tuning. The bass is dipped just a tad while adding a bit more upper mids and treble. It's essentially a cleaner version of tuning 00. Although the bass is still slightly bloated, it's not an issue. My only complaint with this (which also applies to tuning 00) is that the splashy treble sometimes sometimes jumps out at you and the lack of treble extension makes the tone a little wonky. The Legacy 3's tuning is better IMO. There's just a much better balance between the mids and the bass in the Legacy 3 despite it's lack of treble. The Voyager 3's 10 tuning passes the bar for decent and that's about it.


Tuning 01 and 11: Like 00 and 10, these tunings are quite similar. For the most part, I dislike both. Compared to the 00 and 10 tunings, these sound bloated and muddy with a severe lack of presence in the mids due to a very small pinna gain. The 01 tuning is worse by a little bit. These tunings essentially dampen the uppers and treble. Because the low-mid treble hump is tamed, there is a further lack of clarity and the treble now just sounds cheap. Interestingly enough, the 11 tuning graphs fairly closely to the pre-2020 CFA Andromeda. While I also did not like the Andromeda's tuning when I had a chance to demo it, it was a lot better than this. I think the significantly improved technical performance and upper treble extension of the Andromeda play a big part in that. All that being said, I can see how some people like this sort of laid back, warm tuning. When I compare it directly to the Legacy 3 which has a much better balance, the 01 and 11 tunings are hard to enjoy. But after a good 30 minutes or so my ears started to adjust and I began to enjoy the music through this tuning. For some tracks, the lack of pinna butchers the vocals. But depending on the mix, other tracks aren't really affected at all. Of course, YMMV depending on what you listen to.


Conclusion: It's hard for me to recommend the Voyager 3 beyond the novelty aspect of playing with tuning switches. Its technical ability is middling at best. The best tuning setting is relatively decent. For $160, the Voyager 3 really shouldn't exist. To be fair to Thieaudio, the Voyager 3 was their very first foray into IEMs and the <$200 market is phenomenally competitive. The one case where I can see the Voyager 3 be worth it is if you're curious about tuning switches as I can't readily think of any other <$200 IEM out there with switches that meaningfully contribute to the overall sound. Though there are a number of other IEMs out there with tuning filters.

You can see the channel matching is quite good on the Voyager 3.

Here are the four tuning options. You can clearly see that if the second switch is in the "up" position, it has a lot more upper mids and treble presence.

Legacy 3:


Bass: The bass of the Legacy 3 extends down to 20 Hz with the slightest of roll-offs. It has a nice sense of impact and responsiveness that makes up for its relative lack of texture and nuance. As far as budget IEMs go, this is one of the better bass responses I've heard. It provides the much needed low end presence that makes music engaging while maintaining a balance that doesn't emphasize either subbass or midbass.

Mids: The transition into the low mids is tastefully done. A lot of budget IEMs can struggle here but the Legacy 3 handles it with no issue. There isn't much bass bleed or muddiness from the DD and nor a jarring DD/BA transition at the crossover. The Legacy 3 has just a hint of warmth in the lower mids. The upper mids has plenty presence with a forwardness that brings out clarity in vocals and electric guitars. Combined with the slight warmth in the lower mids, the Legacy 3's mids response nicely handles the tone of a majority of instruments. From the quiet strumming guitar coupled with a vocalist's whispered words to the screaming overdriven notes of lead electric guitar, the Legacy 3 is well suited to modern pop/rock genres.

Treble: Where the Legacy 3 stumbles is its relative lack of treble. Right at the transition between the upper mids and lower treble, there is a sharp drop-off in volume. This is not to say the Legacy 3 cannot produce treble at all. It can and the Legacy 3 is certainly not a dark IEM. It is simply de-emphasized. The sharp, crisp sound of the hats or delicate shimmer of the the cymbals have less presence, leading to a duller tone. For those sensitive to treble, the Legacy 3 would be a good choice as it is far from fatiguing with no sibilance issues. I liken it's lack of treble to that of the Etymotic ER4 line. It's there but its far from the focus. I find that the overall tonality of the Legacy 3 isn't negatively affected by this, with the exception of instruments that specifically rely heavily on the upper harmonics.

Technical Ability: On a technical level, the Legacy 3 is a solid performer for it's price bracket of about $120 but won't be taking home any medals. Imaging is a bit better than your standard budget IEM though its soundstage is mediocre with a flat 2D, in-your-head type of sound that's in line with 90% of other IEMs out there. Resolution and separation are competitive with some of the better products in this price range but are decidedly a step down from the best performers (i.e. Etymotic ER2, Tin Audio T4, Moondrop Starfeld).

Conclusion: As a whole, I quite like the Thieaudio Legacy 3. While it lacks the treble response that I generally look for in my IEMs, the mids balance and bopping bass response kept me listening to it for longer than I'd normally do for a review. While I don't think it provides the greatest value from a price/performance standpoint, it is a solid contender to the $100 or so IEM range. Where I see the Legacy 3 be undisputed is as a CIEM. The number of CIEMs you can buy <$200 can be counted on one hand and the Legacy 3 has a firm foundation in both tuning and technical performance.

My set has very slight imbalance but this is not noticeable at all.


You can see in this graph that regardless of what setting you're on, there's effectively no difference.

*Disclaimer: The Legacy 3 has a unit variation issue. Antdroid has previously documented it here. My unit has the old (orange) tuning. Based on the measurements, I would probably enjoy the newer tuning even more. That said, I still find the old tuning enjoyable as demonstrated in my review.

Should You Buy It and Which One?
As evident in my review, I would consider the Legacy 3 to be worth it while the Voyager 3 can be safely ignored. The Legacy 3 beats out the Voyager 3 in almost all respects unless you specifically want that Andromeda-like laid-back, warm tuning with minimal vocal forwardness from the Voyager 3. At $120, the Legacy 3 is a good value and I feel comfortable recommending it, especially if you want a CIEM. And while there may be better value propositions on the market, those may not fit your needs. As always, make sure you think about what exactly you want out of your IEMs and do more research into what fits your needs. If the Etymotic ER2, the Tin T4, or Moondrop Starfield have some sort of deal breaker for you, the Legacy 3 is worth a look.

glad i read this before buying, cheers. good review


500+ Head-Fier
Pros: build quality, cable,
Cons: average technicalities, switches affect too wide of a frequency range, tuning is not competitive in this price range
The ThieAudio Voyager 3 is an in-ear monitor (IEM) utilizing three balanced armature drivers per side. The Voyager 3 uses a three-way crossover with two separate sound bores. It also has low and high tuning switches which allow the user to adjust the level of bass and treble.

The ThieAudio Voyager 3 retails for $159.00 at Linsoul. I was provided with the Voyager 3 by Linsoul in exchange for a fair and objective review.

This review is also available on my blog:

I have used the ThieAudio Voyager 3 with the following sources:
I have tested these headphones with local FLAC and Spotify Premium. Visit my page to get an idea of what I listen to.

The ThieAudio Voyager 3 comes in a rectangular black cardboard box. The box is unmarked apart from a circular seal emblazoned with the ThieAudio logo. The package I received included a zippered semi-rigid carry case, a detachable 2-pin cable, and a small pin-like tool that resembles a SIM card ejector tool for adjusting the tuning switches.

The carry case exterior is brown synthetic leather with a cloth-backed interior. It has a small mesh pocket on the roof of the lid for storing accessories. The case is one of the roomiest I have seen included with an IEM of any price.

The ThieAudio Voyager 3 has clear acrylic housings with brightly colored faceplates and a pseudo-custom fit. The faceplates have a wood grain pattern and are inlaid with the ThieAudio logo in silver text. What I assume is the unit serial number is printed in silver on the inner face of the housing. The BAs, wiring, crossover, and BA tubes are all visible through the shell. The 2-pin connectors protrude slightly from the surface of the housing and are compatible with QDC-type cable connections. The sound bores have no exterior mesh cover. The nozzles lack a lip for securing eartips but I did not have any eartips come loose using the Voyager 3. The nozzles are thick and wide, which could limit their use with aftermarket tips. In addition to the stock silicone eartips, I used Moondrop MIS T55 eartips with the Voyager 3.
The eight-core silver-plated OCC copper 2-pin cable included with the ThieAudio Voyager 3 is gorgeous. It is soft, flexible, and resists tangling. It is moderately microphonic, but this can be mitigated with the clear plastic bead-like chin-adjustment slider. It has a straight 3.5 mm termination with metal hardware and good strain relief. The Y-split is metal as well. Both the Y-split and the 3.5mm jack have carbon fiber inlays. The cable uses preformed clear plastic earguides without memory wire. The 2-pin connectors have raised markings to indicate left and right, but the markings are so faint that they require scrutiny to distinguish. As in other similar cases, I would prefer to have colored indicators to distinguish the channels from each other.

The ThieAudio Voyager 3 is intended to be worn cable-up. The earpieces have a moderate insertion depth, and while I found them to be comfortable for the most part, the thickness of the nozzle may be troublesome to those with narrow ear canals. Secureness of fit and isolation are excellent.

ThieAudio Voyager 3 tuning options (left side only)
My measurements were conducted with a Dayton iMM-6 microphone using a vinyl tubing coupler and a calibrated USB sound interface. The headphones are driven using my Element, which has an output impedance of no more than 1 ohm. The measurements use a compensation file derived from relating my raw measurements to published measurements from Crinacle and Antdroid. The measurements are presented with 1/24th smoothing. There is a resonant peak around 8k. Measurements above 10k are not reliable.

The ThieAudio Voyager 3 has a V-shaped tuning in all its switch configurations. I find the ThieAudio Voyager 3 most enjoyable in its stock configuration, with neither switch activated.

With the low-frequency switch in the off position, the Voyager 3 has a mid-bass emphasis. The bass has adequate speed and respectable articulation but limited texture and impact. Bass resolution is middling. There is considerable mid-bass bleed into the lower midrange, which creates congestion. Switching the bass switch on elevates the sub-bass and the lower midrange, creating a more uniformly bassy presentation. I found this setting overwhelming and muddy.

With the high-frequency switch in the off position, the Voyager 3 has a warm, thick midrange. Male vocals have good body but female vocals sound slightly muffled and overall vocal intelligibility is below average. With the high-frequency switch on, vocal intelligibility, presence, and overall clarity improve. However, this comes at a significant cost to the smoothness of the midrange, introducing strain and sibilance. Midrange timbre has noticeable plasticity.

The lower treble is strongly emphasized. Although generally unfatiguing to my ears, there is severe upper treble roll-off. Air and detail retrieval are limited. The Voyager 3’s soundstage is average in both width and depth. Imaging and instrument separation are also average.

The ThieAudio Voyager 3 can be easily driven to a comfortable listening volume with a competent dongle. I did notice hiss with the Radsone Earstudio HUD100 USB DAC/AMP, but not with any of my other sources.

The ThieAudio Voyager 3 is a strong effort in terms of physical design and build quality. However, I do not feel its tuning is competitive at this price point. The inclusion of tuning switches at its price point is novel, but I recommend future efforts by the company incorporate switches which target narrower frequency bands instead of splitting the frequency response down the middle.

New Head-Fier
Pros: Warm sound with full body
detailed mids, with wide panorama
beautiful voice presentation
soft, dry bass, with good punch...
Cons: ... fast sub-bass roll-off and not always clean
not the best treble extension
not a good all-rounder and demanding when it comes to the music material
Rating: 8
Sound: 8

THIEAUDIO is still green behind the ears and was founded in 2019. It is part of the LINSOUL AUDIO distribution and thus represents the first own house brand, so to speak.
The VOYAGER 3 and 14 are gaining more and more popularity among audiophiles, even if there is not much to read about them yet.
This review is about the 3-BA driver configuration, the VOYAGER 3.


For its 3 BA drivers, the VOYAGER 3 is quite clumsy, although so much space would not have been necessary. The AUDIOSENSE T300, for example, impressively proves how to fit three BA drivers into the smallest space.
However, the VOYAGER 3 is also available as custom for an additional 50 €. These are usually a bit bigger than universal IEMs and if they are adapted to the ear, you won't notice that much, but here in the universal version the sound tubes are a bit thick and can easily press in the ear canal if you use too big tips. This makes it a bit tricky to find the right tip to achieve a good isolation, which is excellent with an optimal fit. Because there is no air opening at all, there can be a negative pressure, especially with silicone tips, which is a bit unpleasant.

There are dip-switches on the case, with which the sound can be influenced, but more about this below. Otherwise, the VOYAGER 3 looks very appealing with its individual faceplate and makes a robust impression.

The scope of delivery includes a selection of foam and silicone tips, as well as a large imitation leather case, which is the same case as the REECHO SPRING, but in black.
THIEAUDIO relies on a 2-pin connector that is turned outwards and can be found, for example, on the newer Knowledge Zenith models. The corresponding 8-core cable is of very high quality.


The V3 uses a somewhat unusual configuration of two Knowles CI-22955s and an ED-29869, with one of the two 22955s taking care of the bass and the other of the midrange. However, they are routed through the same sound tube, with a 1500 Ohm filter. The 29869 for the tweeter has been equipped with a 680 Ohm filter, which should bring unpleasant peaks under control, but does not completely satisfy the user in each of the adjustable sound characteristics.
A short explanation: We have 2 dip-switches, resulting in 4 different settings. With switch 1 the bass can be influenced, with switch 2 the treble.
But now it is the case that the bass is really only influenced to a very small extent, no matter which setting I choose. This means that there is only a very small difference between 1on/2on and 1off/2on and also between 1off/2off and 1on/2off. Therefore I limit the evaluation of the bass to the general performance and the mids and highs to 1on/2on and 1off/2off.

It's important to note that my evaluation is based on the 1on/2on configuration.

The bass can be influenced by the first dip-switch, but this doesn't change the quality or the keynote, only the quantity. It's a little bit sloppy and not quite level stable. In addition, it drops quickly in the low bass, can tend to boom a bit and makes the mids appear a bit hollow at times. On the subjective positive side: it's soft and warm, but still has a firm kick and a full body. At the same time it has a fast reaction time. Thereby he plays quite linear. A typical BA bass with a dry and warm character. In this case a bit too warm and not clear and structured enough. This is slightly corrected with the dip switch 1 to off, but then you have to make do with slightly less quantity. Qualitatively nothing changes.

The mids are a bit of a double-edged sword. Basically they are pleasantly warm and soft. Vocals have a quite natural timbre and have a nice presence due to the upper mids and pushed highs without being too obtrusive. The V3 is perfect for vocals if you like it a bit more relaxed. Orchestral music sounds just as good, especially when it comes to cellos, violas and instruments in general that rely on a full body. The mids are definitely influenced by the bass. Now you can decide for yourself if you want to consider this as an advantage or a disadvantage. One thing is certain, however, that the mids will not be pushed too far into the background and will be able to stand up well.

The trebles don't have an extreme extension, but that makes the V3 quite relaxed in the high frequencies. Nothing for treble fanatics, or for analytical listening, but still enough information is provided to keep it exciting and to avoid the impression of being overwhelmed by the bass and mids. But you notice that the stage doesn't really open horizontally, which would be favoured by more playful highs, but instead is very strong in the panoramic image and depth. Unfortunately, sibilants are always a topic here.

If both dip switches are set to off, the high frequencies are noticeably smoothed and flattened. Unfortunately this does not interest the sibilants, which are still present. After the change, the mids look a bit duller and set back, but this is basically only subjective, as the highs don't absorb the warmness anymore. The V3 sounds flatter and less exciting, even though this is generally not an attribute of the V3. However, you'll have fewer problems in this configuration if you're sensitive to high frequencies. Voices lack a bit of liveliness and the details are also more limited in their perception, as they are now more subtle, but of course don't disappear. Basically, you can do something with the setting if you like it even warmer, more unagitated and a little more intimate. For audio books and films perhaps even a welcome adjustment possibility. But if I only had this setting available, the rating would be lower.


The idea of changing the sound and optimizing it with a dip switch on the crossover is certainly nothing new, but it is ambitious and certainly a nice feature, although I would have hoped for a bigger change here. Especially the bass switch has little influence.
Even though I basically like bass, my favourite setting is still 1off/2on. Here I have to do without a little bit of bass quantity, but it sounds more subjectively defined. In addition I have the increased treble and due to the additional energy, airiness, transparency and resolution I'm willing to accept some peaks or sibilants. The VOYAGER 3 is a really good IEM and will surely be able to pick up some more fans with its sound characteristics. But it could use some more fine-tuning, because it has the technical requirements. So it doesn't manage to attack the top and is placed in the upper midfield. Nevertheless, I don't want to make the V3 worse than it is. You just have to know what you want to hear with it, because it doesn't turn out to be an all-rounder. So it's stunning with some musical templates (classical, country, singer-songwriter and basically pop), but with others it leaves you a bit perplexed (rock, EDM, hip-hop) and besides that the V3 is very bitchy with worse recordings.

No, unfortunately you're right, I switched it. I'll change it in the review.
So i am not sure if they make all their V3s wrong or they just intentionally tune it like that. It's unusual to damp a 29689 with white damper.
I think they want it like that. For Legacy 3 they used the red one :)

  • Thieaudio Voyager 3 IEM
  • Eartips - silicon tips(S.M.L)
  • Cable
  • Carrying case

Build/Design: Is nice ,the shell cavity is composed of transparent acrylic resin and you can see the internal structure with the 3 BA, has a unique real wood faceplate, it has 2 dip switches and 2 sound bores

Cable: Is good quality, 8 core silver cooper foil, nice, soft feel (Cable is Tripowin C8)

Ear Tips: They are tip-dependent. With with stock tips the sound was a little thin , with a strange " wet like " sound. I tried spinfit model cp155 and the sound didn't change very much. After listening and switching a lot of types of eartips, i found that MEMORY FOARM EARTIPS REALY CHNGED THE SOUND. The eartip must be inserted deep on the nozzle so that the sound bores are close to the top of the eartip (this will help you get direct sound from nozzle with no reflections). Comply eartips are very good (comply audio pro or Isolation T600), Spinfit (wich are my favorites) does't work so well with voyager 3 , they improove soundstage a little but overall sound is thinner.
With the memory foam eartip you will get a full-body sound.

Comfort/Fit: Is excelent, no problems using them for hours

Power: They are low impadance - 14 ohm and very sensitive to hiss, but the good news is that you don't really need an amp for them, even if i see benefits of using one

Isolation: Is very very good, one of the best i tryed


Eq Customization Switch : There are 2 switches : left for the lows and the right for highs

With both switches off- most ballanced config, best eq for mids, never harsh or sibilant but to a little too low - but easy to listen
With both switches On - The sound is more V-shaped, soundstage improoved , more air, more treble details, mids a little behind (not too much) - Overall pleasing signature, fun to listen
With Bass switch on and High switch off - The Bass, sub-bass is elevated, the mids still reccesd and highs relaxed
With High switch on and Bass switch off - light bass, has extended treble, more airy and more details but can be too accentuated in the air region for some genre like rock or if you are sensitive to high frequencies (especially if you are using silicone tips), if you like high, maybe it's the setting for you.


For sound testing i used : Pioneer XDP100r and Hiby R3 , DAP's alone and paired with: Chord Mojo, Aune B1, Topping NX1s, Fiio BTR3 and i listened to some Flac files.


After geting the right eartips the sound is full-body, ballanced, nice warm tuning, with very good detail retrieval (for the price), separation is above average (very good for the price) but not the best over much more expensive iems, soundstage is a little above average ( it's bigger in depth, not so wide),the mids are detailed and vocals are very nice and clean especialy female vocals. The Bass is there, is resolving but doesn't have the DD impact and weight, i don't foud it lacking basse only the sub-bass region where is a bit to light.

Overall: I think this is a good value item and I reccomend it for a clean, balanced, very detailed and natural and versatile sound, very nice for vocals. I mostly reccomend it for audio monitoring, but also for music lovers that want to hear everything in his favorite music .I think a good buy for this money, but beware of using the right eartips, they really make difference

Cable: One of the best stock cables I have seen. Not the thickest cable but thicker than average and feels very sturdy (although the plug and divider feels cheap and very light weight for being metal).


Build: Made out of resin and even the nozzle is made out of resin too. There are 2 switches on both of the left and right piece that can only be changed by using something thin and sharp (like a needle or a sim card ejector). The 2-pin plug is similar to the “type C” that KZ uses, which will make your cables stick out if they aren’t meant for it. Very transparent color so you can see inside it quite clearly. The nozzle has 2 sound bores. There is no vent on it, so that will help the isolation.


Fit: The fit is very good but not at the top (the Audiosense DT200 takes that spot), and stays in place without needing to adjust it from time to time. People with smaller ears might have a problem with them though, because they are on the bigger side. They protrude a bit from your ears, so they are definitely not for sleeping.

Comfort: With the good fit comes good comfort, although since it is on the bigger side that means that you will feel more heat with them than smaller iems and that can be a problem for longer listening sessions.

Isolation: Big size + no vents = excellent isolation, the isolation is second only to iems such as the Audiosense DT200 and T800 and not by much.


Setup: Fiio M11, stock cable, stock large silicone tips

Foreword: Before I begin talking about the sound, I want you to know that the Voyager 3 has a lot of hiss. I am using the 3,5mm output on the M11 which has 1 ohms of output impedance with the Voyager 3 while I am using the 4,4mm output which has 2 ohms of output impedance with all my other iems including all BA iems like the Audiosense DT200 and T800, and the voyager 3 has by far the most hissing.

So, if you do not like hissing then I advise you to stay away from it if you do not have something close to 0 output impedance (JDS Labs Atom has 0,1 ohms of output impedance and that is completely silent)

Switch modes:

1 up +2 up
: Stock configuration that is u-shaped and my preferred configuration. My review will be based on this configuration.

1 down + 2 up: Sub-bass boost, but makes it a bit too boomy for me in the sub-bass, sacrificing speed and tightness.

1 up + 2 down: Treble reduction, makes it warmer and more L-shaped, but sacrificing details, soundstage and separation.

1 down + 2 down: Bass boost, while reducing treble, very warm and sub-bass is boomy same as the 1 down + 2 up configurations but the reduction in treble makes it lose A lot of details and makes it sound lifeless.

Lows: Typical BA bass and is sub-bass focused. The bass is boosted but it is tight and fast so it is very clean, but lacks the punch DD bass makes. Not the worst BA bass but nothing special, except that it has the right quantity to make it fun to listen to.

Mid-bass: mid bass quantity is on the neutral side and too low for my tastes. But it is tight and fast so it stays clean.

Sub-bass: has more rumble than some other BA iems but that also makes it sound less clean. It will sound tighter when called for so that is good since it is versatile. Speed is a bit slower than average.

Mids: Well balanced between male/female vocals, but since the treble is a bit boosted it makes female vocals just a bit more forward than male. Since Bass and treble is boosted it will make the mids seem a bit recessed.

Female-vocals: female vocals sound a bit more forward than male vocals but that also makes it more prone to sibilance.

Male-vocals: male vocals sound a bit behind the rest of the spectrum, and can sound a bit thin but quality is good.

Highs: Treble is a bit boosted alongside the bass which makes this a soft U-shape. The extension above around 13kHZ is quite bad but if you use EQ it will make it sound more lifelike. Treble is something I dislike about the Voyager 3 without the use of EQ it is both a bit lifeless and sometimes sharp, but with EQ it sounds more natural even though it is boosted and more likely to be sibilant.

Soundstage: a bit bigger than average but not impressive.

Tonality: The Tonality is U-shaped with bad extension above around 13kHZ and timbre is below average.

Details: average details, but with EQ applied to over 13kHZ makes it sound much more detailed and crisper which would make it have above average details.

Instrument Separation: average separation, but a bit above average with EQ applied over 13kHZ.

Songs that highlight the IEM: , , ,
Good genres: pop, Jpop, EDM, Hip-Hop, house

Bad genres: Acoustic songs/genres, rock, metal,


Audiosense DT200:
DT200 has the better timbre and overall sounds more natural due to having less treble boost and the better timbre. Voyager 3 has a bit better bass quality and technicalities. Voyager 3 should suit more people due to having the switch system.

DT200 is an L-shaped iem, while the Voyager 3 can go from U, L and warm sounding. Voyager 3 has the better cable but the rest of the packaging with the DT200 is better. Voyager 3 is better for versatility when it comes to sound preferences and more “fun” while DT200 is better if you want naturality.

Audiosense T800(stock + Green filter): T800 has lower Treble quantity but has better extension and quality. Mids is more recessed especially male vocals and quality is a bit better on the T800. Bass extends better and sounds much more natural (similar to a DD driver) but also much more boomy and slower. Bass quantity is much more boosted and is on a basshead level. Technicalities are a bit better on the T800.

They are both U-shaped but the Voyager 3 is more versatile due to the switches. Bassheads should like the T800 more, but otherwise I recommend the Voyager 3 instead because of the better price/value and because the bass is much cleaner on the Voyager 3.

Blon BL-03: 03 has more bass quantity, a bit slower and looser but has DD punch since it is a DD iem. Male vocals are a bit more forward on the Voyager 3 while the 03 has a bit more female vocal. Treble quantity is more on the Voyager 3 but it has worse extension.

Technicalities are much better on the Voyager such as soundstage, instrument separation and details but timbre is leagues above on the 03. 03 suits you if you like boomy bass and excellent timbre. Voyager 3 is better if you want tighter/faster bass while also having access to switches.

Shozy Form 1.1: 1.1 has much better bass quality and quantity. It is just as tight and fast while having the texture of a DD driver and sounds very good, it can also rumble just fine. Mids are better on the Voyager 3, sounding more natural but quantity is the same. Treble on the 1.1 has better extension but feels less natural than the Voyager 3, the 1.1 also has a bit lower treble quantity.

Soundstage is bigger on the 1.1 but details and instrument separation is better on the Voyager 3. 1.1 should be better for people that want that good DD textured bass while still being tight and fast, Voyager 3 is better for versatility and for more vocal centric songs/genres.

LZ A6 (pink filter): A6 has more treble quantity while also having much more extension, air and quality. Mids are more forward on the A6 and quality is much better. A6´s Bass is tighter and faster and also have much better texture and quantity is just a bit lower. Soundstage, instrument separation and detail are incomparably better on the A6.

Timbre is just about the only thing better with the sound on the Voyager 3 and versatility goes to A6 with its 9 different tuning filters in comparison to the Voyager 3 with “only” 4 different switch configurations. Isolation, fit and packaging is better on the Voyager 3 though.

Conclusion: in conclusion the Voyager 3 is a very versatile iem when it comes to personal sound preferences, offering 4 different switch configurations. But I cannot give it a high grade due to there being other iems that are offering the same or a similar tuning for cheaper price or better for only a bit higher price. The voyager 3´s saving grace is the stock cable and that it has switches and having 3 knowles BA for a relatively cheap price (at least in comparison to other iems that have 3 knowles BA). Thanks for reading.

are you sure about your switch description? In my case 1 is responsible for the bass and 2 for the treble. on = boost

so 1off/2off is definitely not a bass boost, but because the treble is taken back, subjectively it might look like
@DallaPo To me when both are off (down) the bass is heard more than the treble, so to me it is more of bass boost. But as I didnt like any of the configurations except the stock one, I can be wrong.
Yes, you're right, that's why I meant this subjectively by the loss of the high frequencies, the bass is of course more effective, but this is not the case in terms of output level.
