SoundPEATS Truengine 3 SE VS. Sonic: Which One Best for You?

I will compare the Truengine 3 SE 3 SE vs. Sonic, two of the top earbuds from Soundpeats. I have made this comparison many people have asked me which of these two models is better.

If you are interested in buying one of these earbuds, don’t miss a single section of the comparison, as I have tried not to leave out a single detail.

SoundPEATS Truengine 3 SE vs. Sonic Review

Price Comparison

One of the essential points of the comparison is to know the current price of both products and analyze the lowest price. They have been in the sale. Amazon is where they are currently the cheapest.

In this store, prices change every day. If we have a little patience, we can save a lot of money—Now, both earbuds are priced under $50. You will get a lot of good features at this low price.


The presentation and the contents of the two products are pretty similar. However, there are a couple of differences. The first is that the Truengine 3 SE box is slightly larger.

The sonic earbuds come inside the case, while the Truengine 3 SE earbuds are separated. The most significant difference comes with the pair of premium ear cushions that the Truengine 3 SE has with a couple of ear cushions called true gripo, which we will discuss in the section on fit and comfort.

As for the regular ear pads, we have the typical ones that usually come with in-ear earbuds. The difference is in their hole for the audio output being more significant in the Truengine 3 SE.

On the other hand, the charging cable’s length is 14 centimeters longer in Truengine 3 SE, 37 centimeters, and 23 centimeters, respectively. In short, evaluating the presentation and the content of both products.

I prefer the Truengine 3 SE because of the premium pads included and, above all, because of our 14 cm long cable. Depending on where we put the case charge, it can be advantageous.

Case Design

The design of the Truengine 3 SE case is very minimalist, its color is matte black throughout, and the only thing that makes it different is the Soundpeats name on the top.

The sonics are the opposite. We have more graphic design. Its color is gray for almost the whole set. We have a kind of wavelength in light bronze color. Likewise, in the upper part and the inner, we have the logo and the name of Soundpeats.

On the back, right in the center, we have the type-c charging port on both cases, along with a LED light that is located in a different position. When we open the case, the first difference is that the Truengine 3 SE has four led lights and an engraving of a battery.

In the sonic, we only have one led light. When we put the earbuds sonic in the case, it covers the initials L and R. In the Truengine 3 SE. With the case manufacturer, I have to say that I wouldn’t say I liked either of them. Both are made of plastic and are of low quality. However, I had the feeling that the Sonic case had more quality.

Earbuds Design

The earbuds Truengine 3 SE have a matte color practically all over the earphone. However, it has two details that make them different. The first one is the triangle of bronze color that it has in the front part.

We can also see the two microphones it incorporates and, more or less in the middle of them, a pilot led. On the other hand, the Sonic has only one microphone, and the S logo delimits its led pilot on the front.

The second detail that makes them different from the Truengine 3 SE is that on the inside, as you can see, there is a kind of transparent capsule, where inside, you can see the two drivers that it incorporates.

The Sonic has a more circular design than the Truengine 3 SE, and their colors match their charging case, sharing the same wavelength in a light bronze color that they have around.

Dimensions and Weight

Both cases have the same elongated oval shape. Their dimensions are more or less similar, but where the difference is mainly in length. The Truengine 3 SE has a distance of 7cm and the Sonic 6cm.

That centimeter difference is noticeable at a glance. In terms of width and thickness, the difference is minimal. The earbuds’ dimensions are also similar, but the slightest difference is already noticeable in the ears.

Both have a relatively large body, but the Truengine 3 SE takes up more space in the ear. The Sonic case’s weight without the earbuds is 6 grams less than the Truengine 3 SE, and with the earphones inside, the Sonic’s importance is still less than 34 grams.

Respectively and finally, the weight of earphones is the same in both models, 6 grams. Considering all the above, I would choose the Sonic if I had to choose a charging case.

It weighs less, measures less, I find it more aesthetically pleasing, and it is practically free of fingerprints and dirt. The latter happens very quickly with the Truengine 3 SE.

I find the Sonic much more excellent as far as the design of the headset is concerned, but when I wear them, I wouldn’t say I like the look as they stick out of my ears, whereas the Truengine 3 SE stick out a little less, and I want them more aesthetically both from the side and from the front.


In the sonic, we have a physical button delimited by the triangle of clear bronze color in the front part. In the Truengine 3 SE, we have a tactile zone delimited by the acronym S in the triangle’s interior in the front aspect.

If you press on the edges of the triangle, you will see that the earphone does not respond. You have to press just in the center of the acronym S. As for the functions that make one and the other. There is only one difference: that in the sonic. We have an extra process which is the gaming mode.

On the other hand, the touches given to activate or deactivate these functions vary a little. The touch zone of the Truengine 3 SE is very well delimited, it is more comfortable, and I have had practically no false contact.

This last one is because we have pretty thick edges throughout all the headsets. The shape of the headset itself is designed so that we don’t touch it when manipulating them with our fingers.

This area accidentally they are very ergonomic in this sense. As I said in the review, the Sonic’s physical button is a little challenging and can be annoying in long presses.

Indicator Lights

The indicator lights of the cases and the earphones show us precisely the same thing. But the Truengine 3 SE shows us with more precision the charge percentage of the case’s battery.

They have four pilots, and in my opinion, it is more intuitive to see them. This way, the Truengine 3 SE, when they have a low battery in the earphone, does not automatically show it.

This means we must press the tactile zone when a headset runs out of battery. When we do this, the red light of the headset blinks, and it indicates to us that without battery, whereas the sonic yes, automatically shows it, and its led pilot flashes in orange color.

Fit and Comfort

Using the two earbuds at home with the mobile or pc, I have not had any problems with the fit, and my experience with them in this sense has been positive. As I said in the individual sonic review, the situation in the adjustment came when I started to move with them on, I noticed how little by little they were coming loose from the ears until they finally fell off.

With the Truengine 3 SE, the same thing happened to me when I went running with the standard pads. They fell off almost instantly when I changed them for the truegrip that includes these.

The adjustment improved surprisingly, and I could go running with them without them falling off. These pads are made of foam rubber, and the truth is that I notice that they insulate better from external noises than the normal ones and the fit is more secure.

The bad thing is that they wear out with time and use. So I will have to buy new ones if they sell them, which I don’t know. The fit of the trending in general terms has offered me much more security than the sonics. If we talk about comfort, the Sonic is lighter and more comfortable after having both on for an extended period.


To start talking about this section. We have to know what kind of chip the two headsets have. In the Sonic, we have the chip 3040 from Qualcomm, which in the last year is, replacing the 3020, the chip that the trendings have.

What does this mean? The 3040 chip is much more modern than the 3020, which means we will have better connection stability, lower latency, and much lower power consumption, among many other technical characteristics.

But let’s get to the point of the differences I have detected between having the 3040 chip and the 3020 chip. The most important is that the Sonic can operate both earbuds at the same time.

By connecting, it only detects one earbud in our device, unlike the Truengine 3 SE. You have to connect them separately to our device to use both simultaneously. How does this affect this Truengine 3 SE?

Let’s suppose that we are listening to music with them, and our device has been connected to the right earphone them when we put the right earphone in our case. We will see a slight interruption of the audio of about 3 to 5 seconds since our device has to disconnect the right earphone and connect the left one.

This interruption in the sonic does not happen since chip 3040 can make the left earphone assume the connection when putting the right one in the case without going through any reconnection process.

Another curious thing I have detected is that when I listen to Sonic music, and one runs out of battery, the one with a little more is automatically reconnected.

The truengine doesn’t do this, and when one runs out of battery, the other one stays on standby with the fixed white light on, and you have to connect it manually to continue listening to music with it.

I leave you with the time it takes for the earbuds to enter mode pairing when you take them out of the case, as there is a slight difference. If you had a connectivity problem, you would have it sooner in the Truengine 3 SE than in the Sonic.

Sound Quality

The Million dollar question: which one has the better sound quality? After 1 hour of listening to different songs on Spotify and constantly changing my earbuds to appreciate the difference in the other frequencies.

I have concluded that the high frequencies are much higher in the Truengine 3 SE, are more present, and do not distort when set at 100% volume. The difference in this frequency is quite significant, as in the sonic.

They are much lower and less present. We move on to the mid frequencies, here again, the Truengine 3 SE win. The instrument’s separation is good in both earbuds, but the Truengine 3 SE is more noticeable, and the mids-bass is much more forceful.

I have appreciated the bass frequencies with more quality and forcefulness in the sonic. However, the difference here is not as big as in the treble and mid frequencies. In both of them, the bass frequencies are very present.

In favor of the sonic, The naturalness of the instruments is much better in these earbuds. In the trending earbuds, they sound more forced. A debate generated around the sonic is that it sounds feeble.

The truth is that if we compare them with the Truengine 3 SE, they sound much louder. The Sonic is an earbud that, to enjoy the music, you must be at 90% or more volume to appreciate the different frequencies. If we put them at 60 percent or 70, the truth is that the sound and quality are poor.

To give you an idea of the maximum volume of one or the other, when we put the Truengine 3 SE at 76% volume, it is the same as setting the sonic at 100%. I prefer the sound quality of the Truengine 3 SE.

They are far superior in high and mid frequencies. They have a livelier sound and have that bonus of maximum volume. I do not want to say that the sound quality of the Sonic is not worth it. This article will recommend both earbuds for their sound quality as they are both quite good.

Microphone Testing

The test I have carried out to analyze the quality of the microphones is entirely accurate. I have asked the people who listened to my voice to get an idea of which of the Two earbuds has a better microphone.

When I used the Truengine 3 SE on the pc, my friends told me that my voice was better than the Sonic. However, I have to say that I could have conversations with them on the pc without any problem.

Finally, I could hear my friend’s voice better with the Truengine 3 SE. To analyze them in telephone calls, I put the television in the background at a medium volume to know which of the two reduced the TV’s noise most, and here the thing changed slightly.

The voice of my relative was perceived with much clarity and more volume in the sonic. According to my relative, when I used the Truengine 3 SE, he said that my voice was heard above the background noise of the television (in short, the Truengine 3 SE managed to reduce the background noise a little, giving priority to my agent) on the contrary.

When I connected the sonic, he said that my voice was perceived worse and that the TV could be heard more in the background. Even with the two earbuds, I could have a conversation with him.

Delay Tests (pubg)

The delay on youtube is low in both models as the application itself can compensate for the delay. It is practically not even noticed, so you will not have delay problems on this platform.

Where you appreciate the delay is playing online video games such as PUBG, the test that you will see below, I have done with my mobile Xiaomi, Redmi Note 8 with Bluetooth 4.2. The sonic delay is much better than Truengine 3 SE, so the sounds go much better to play.

Battery Life

The battery capacity of the case and earbuds in the Truengine 3 SE is 500mAh, without a case battery capacity of 55*2mAH(Earbuds).

Otherhand, the soundpeats sonic battery capacity of 400mha with a case and a battery capacity of 70*2mAH without the case.

In the Truengine 3 SE earbuds, we have 30 hours of playtime and 150 hours of standby time. In the soundpeats sonic, we have 15 hours (earbuds) of playback time and 150 hours of standby time.

Final Word

If I had to choose between these models, the decision would be pretty tricky. The Truengine 3 SE’s most vital point is the sound quality. The Sonic’s most critical point is its battery and connectivity, and you? After having seen this comparison, which one do you choose? If you have any questions about these two, model them in the comments, and I will kindly answer you.
