The VOYAGER 3 made me want more THIEAUDIO products and fortunately I didn't have to wait too long for another listening impression. THIEAUDIO is a project of the well known and well sorted online distributor LINSOUL AUDIO, if you are looking for Asian manufacturers. I was given the LEGACY 3 and what can I say, I am more and more taken with the L3 and for me the better and more mature IEM compared to the V3. There is nothing to complain about in terms of price.
Even if the LEGACY 3 is of course no endgame, it convinces me with its audiophile all-rounder qualities. I am really looking forward to the LEGACY 9, if I should get the chance to listen to it sometime.


The LEGACY 3 comes in the same beautiful packaging as the VOYAGER 3, where THIEAUDIO has come up with something that is not 0815. The packaging can be opened like a book and reveals inside a large and attractive imitation leather case with lots of storage space. Inside there is a good silicone tip selection, even if I still would have wished for foamtips and a wonderful 8-core cable. This is however different in haptics and coloring (okay black is not a color) than the V3. I even find it better, because it feels softer and looks more filigree.

The housing is available in three versions: BLUE-AW11 (blue with glittering faceplate), Mystique and Clockworks. I won't say anything about the Clockworks design, but I find Mystique, or BLUE-AW11 more appealing, but they also cost an extra charge. You can also have the L3 custom made for a little more than 50 €, which was also the case with the V3. Great!

The L3 is a bit more compact than the V3 and also has smaller and rounder sound tubes, which has a positive effect on the wearing comfort. But with a custom, this doesn't matter anymore.
The L3 also uses two dip-switches to influence the sound in theory.

The isolation is excellent and the universal version also has a custom feeling.


With the VOYAGER 3 I have already complained a little bit about not having enough changes when changing the dip switches. Out of the 4 touted sound changes only two became effective, which make a real difference. Well, with LEGACY 3 the influence of this technique is only to be guessed. One My Bass less here, one My Treble more there. The mids don't care about all that anyway. To be honest, it doesn't make sense to write anything about the individual settings. I've been confronted with delusions, thinking that I can hear the difference. That's for everyone to decide for themselves. If anyone is interested, I will write the review using the configuration 1on/2off. But in the end it doesn't matter to me, because even if the settings are nearly identical, the LEGACY 3 is a fantastic IEM in its basic signature.

The bass is very pleasant, it lacks some sub-bass and pressure from below, but it makes up for that with its detailed, dry, soft and dynamic character. The L3 is not a bass IEM, but a very balanced and natural sounding IEM with a slight V-signature. The bass has enough weight to give music the impact it needs, but he leaves it as far as possible, so the L3 doesn't give excessive emphasis in the low end. In contrast to the fast rolling, somewhat bloated BA bass of the YOYAGER 3, which however convinced me with its warm, fast and full-bodied nature, the bass of the L3 is more balanced, deeper playing and more consistent in level. It's not the tightest either, but with its decay it sounds quite natural and not sterile, which would also be untypical for a dynamic driver. In addition, it has texture and a distinctive reproduction of details. Very good dynamic bass, but with upward potential.

Even if the midrange is slightly pushed back a bit in the V-signature, it doesn't matter much. Vocals don't impose themselves, but they are very well placed in the mix, with a slight tendency towards the front. They have a natural timbre and get along completely without any unpleasant accompaniments. Even in rock music they still sound relaxed and airy without being compressed. In addition, the mids dissolve wonderfully and manage to build up emotions with ease. It doesn't make any difference what you put in front of them, I can't make out any gross blunders or discolorations. Very balanced and harmonious. Nevertheless they are not perfect. Sometimes they are almost a bit too smooth and I wish for a bit more clarity and you will hardly believe it: hardness. Nevertheless a real all-purpose weapon.

The highs pick up where the mids left off. Like the VOYAGER 3, they don't have an extraordinary expansion and are more concerned with safety, but the big bonus is that they don't have the sibilant emphasis like the V3. In addition they sound a bit more airy, which is good for the stage in the vertical position. All the necessary musical information is provided here as well, but you can still enjoy it after hours. Transparent and lively with audible micro details. As with the bass and the midrange, this is a high standard that also has substance.

The stage really has to be praised. It is split up into several audible layers and has a distinct character in width as well as in depth, although this is more evident in the former. In contrast to the V3, it opens up more in the vertical direction and also in the horizontal direction it has a slight upper hand.


The VOYAGER 3 is in its price range an IEM with an unusual and interesting signature, with good technical features. The LEGACY 3 is more old-fashioned, but also more serious and adult. For me it can trump the V3 in all areas, even if THIEAUDIO with the LEGACY 3 is still far from reaching the end. If you put performance and price of the LEGACY 3 in context, it is really worth its money for my taste and I can recommend it as an audiophile all-rounder without restrictions, as long as you are not a quantitative bass fanatic or treble head.

In short, I would like to draw the line at the similarly priced SPRING, which I also rate at eye level, but for other reasons. Compared to the SPRING, the L3 sounds fuller and more mature. But the SPRING has the clearer highs and expansion, as well as subjectively higher transparency. In total it is tighter and brighter, which is refreshing. The LEGACY can score with more naturalness and calmness without getting boring. Both very good IEMs, but differently aligned, except the bass, which is qualitatively quite similar, with more body on the L3.



Here the processing plays a role and the usability of the scope of supply. Additionally the appearance, wearing comfort and robustness.

Here I evaluate for me subjectively the price/performance ratio - does not flow into the evaluation!

Z: No Brainer

A: money well spent

B: all right, you can do

C: gives better for less money

D: overpriced

E: collector's price

Daily life:
Here, I focus on the long-term audibility and whether I can hear it well out of the box. This is of course very subjective and therefore only a minimal deduction or bonus.
