Packaging and equipment

TRN T-300 packaging is made in the form of a cardboard box with a hinged lid, over which a dust jacket is put on.

On the front of the package is a picture of the headphones and a brief description.

At the back you can find the manufacturer’s contacts. There could be specifications on a large free area, but for some reason the manufacturer decided not to indicate them.

Accessories are in a small black box.

The TRN T300 package includes headphones, a charging case, a cable, three pairs of silicone tips, instructions and a warranty card.


Charging case

The TRN T300 case is quite large. It is made mostly of black matte plastic.

The lid is partially glossy.

There is nothing interesting on the bottom.

On the front of the case there is a recess for more convenient opening of the lid.

There is a type-c port on the back.

The cover is held closed by magnets. Headphones in their niches are also held by magnets.

The lid in the open position is fixed only due to the overweight back. If the case is tilted forward, the lid closes.

Between markers L and R there is an “invisible” charge level indicator. By the way, the indicator is very informative. The numbers indicate the percentage of charge remaining. The sticks that are located on either side of the numbers indicate the charge level of the left and right headphones.

The case cover is translucent. Through it you can see the lights of the red diodes that glow while the headphones are charging.

The TRN T300 is designed in the “correct” anatomical shape. This has a positive effect on the ergonomics of the headphones (despite their not the most compact dimensions).

Metal sound guides are painted in the color of plastic cases.

The steel grill is designed to protect the headphones from various foreign objects getting inside.

An expansion hole is located between the three contacts and the sound guide.

On the outside of the earbuds, where the logo is, is the touch area. Just below the sensor, there is a microphone hole. A light indicator is hidden above the sensor.

You can find fault with the build quality of the case because of the slight backlash of the lid. As for the headphones, they are assembled flawlessly.


TRN T300 fits comfortably in your ears (does not fall out and does not crush anywhere).

The TRN T300 does not have active sound insulation. But passive sound insulation is very decent. You can thank for this both the design of the headphones (the inner part of the cases fills the auricle quite tightly, thereby preventing the penetration of external noise into the inside of the ear canal), and the ability to use wider and longer silicone tips, which will provide better noise rejection.

Most of the TWS earbuds I owned couldn’t be used with even medium sized SpinFit tips, let alone large ones. TRN T300 is perfectly combined with the largest SpinFit CP100.

The same can be said about the “Sony hybrids”.

With some minor modifications, the TRN T300 can be used with Comply T-400 foams. When using foam tips, the lid closes as it should, but the headphone contacts do not reach the contacts of the charging case a little. To solve this problem, you will have to place several layers of adhesive tape in the recesses on the inside of the lid (the lid will press down the headphones a little, thereby ensuring correct contact).

Connection and communication

The headphones start looking for pairing devices as soon as the case cover is opened.

In the phone settings, the headphones are displayed under the name T300.

No stutters, signal delays, or disconnections detected. But it was noticed that the volume control was not always working correctly using the headphone sensor. I still do not understand what this is connected with. Perhaps a four-tap tap is too complex a combination to recognize.

If the headphones suddenly do not play loudly enough (this happens if the headphones have their own volume control), try turning on or off the “absolute bluetooth volume” switch located in the “for developers” menu.

On Android 8.0 and newer, to enable the developer menu, go to the System section (the last item in the settings menu). In this section, find the sub-item “About phone” (also at the very bottom). By clicking on the “Build number” line 7 times, you will receive a notification that you have become a developer.

There are no comments on the operation of the microphone.


• Play / Pause: Double tap on any of the headphones

• Next song: Long (2 sec) tap on the right earpiece

• Previous song: Long tap (2 sec) on the left earphone

• Volume up: Tap four times corrections to the earpiece

• Decrease the volume: Tap four times on the left earphone

• Call voice assistant: Triple tap

• Accept call: Double tap during the call

• End call: Double tap during a call

• Reject a call: Long (2 sec) tap during a call

To avoid unintentional touching and triggering of the sensor, short single taps are not used in headphone control in any way.


The official specifications regarding the autonomy of the TRN T300 look like this.

• Headphone charging time: 1.5 h

• Case charging time: 1.5 h

• Wireless charging time of the case: 2.5 h

• Operating time of headphones with continuous music playback: 4 hours

• Total battery life (headphones + case): 72 h

My measurements showed the following.

• The headphones charge in just under an hour and a half.

• The case with the discharged headphones installed inside was charged up to 100% in 1 hour 27 minutes.

• With wireless charging, the case gets + 10% charge in 18 minutes.

• With the AptX codec (medium volume), the headphones work for 4 hours 50 minutes

• The headphones work with the AAC codec (volume medium) for 5 hours 38 minutes.

• The total battery life was difficult to measure. Due to the fact that the headphones have been working for a very long time, something constantly interfered with making accurate measurements (I lost count, someone else took the headphones for a while to use it, it was necessary to connect the headphones to another device with a different codec, and. etc.). But judging by observations, 72 hours of autonomy are definitely there.

Wireless charging is integrated into the desk lamp.


Headphones were connected to the following devices

• Player FiiO M11 Pro

• Player Hidizs AP80 Cu

• Various phones

• Various laptops

For sound reproduction TRN T-300 are responsible: 8 mm dynamic radiator with a double magnet, as well as two reinforcing radiators 30019.

TRN T300 has a light, slightly V-shaped, well-balanced flow with a pleasantly detailed sound.

The overall sound character of TRN T300 is musical and well balanced. None of the frequencies try to pull the blanket over themselves and dominate the rest. But the frequency response still cannot be called linear. The reason for this is the slight drop in the low frequency range, which is present in most modern headphones.

The bass of the TRN T300 does not shake the brain with its mass, however, I would not say that it is not enough (the bass is even slightly accented, relative to the midrange). The bass here is not as heavy and thick as, for example, the Apollo Bold. Accordingly, he draws less attention to himself. But in comparison with the same Apollo, TRN T300 bass sounds more comfortable and intelligible.

The mids are highly accurate. The vocals are clean and natural. But as is often the case with V reverse feed headphones, the female voice stands out slightly more than the male.

Correctly tuned armature radiators give the TRN T300 high frequencies good spacing and excellent detail. HF is flat — their upper and lower ranges are approximately in the same plane. Although the treble does not try to hide, they sound rather soft and do not tire with sharpness. Detailing, transmission of micronews, accuracy — everything is very worthy. In general, with regard to high frequencies, in terms of the ratio of different qualities (detail, comfort, uniformity, etc.), they are probably one of the best here, among the TWS headphones from this price segment that I owned.

Pros and cons of competitive headphones versus TRN T300

Sudio Ett

Pluses : Active noise cancellation. The charging case feels sturdier.

Disadvantages : Less quality sound, no support for AAC and AptX codecs, lower overall battery life, higher price.

Differences in sound : Sudio have a darkened presentation with a more linear frequency response. The bass is less deep. The mids are warm and denser in the lower range, but less detailed in the upper range. High frequencies are smoothed and are rather inferior to TRN in quality.

Advantages : Long battery life of headphones, more convenient touch control, support for a special application for adjusting the headphones, the presence of a proximity sensor, the presence of active noise cancellation.

Disadvantages : Less detailed sound, lower overall battery life, uninformative battery level indicator, no wireless charging.

Differences in sound : Tronsmart has a lot of bass, even a lot. If you don’t like massive, accented bass, the Tronsmart sound can sound overweight and tedious. Apollo Bold’s mids are warmer and denser. High frequencies are less natural and, moreover, they can sometimes be lost against the background of underlined lows (in comparison with the subject).

Advantages : Better volume control is implemented. More compact dimensions of the case. Slightly higher battery life of the headphones.

Disadvantages : Less detailed HF, much lower overall battery life, the sensor has a high tendency to accidental touches, more demanding on the size of the attachments, uninformative indicator of the charge level, no wireless charging.

Differences in sound : The lower frequency range of these two headphones is quite similar. The bass of the Kinera is slightly less and slightly less deep, but when using the same tips, the difference can be difficult to notice. At the middle frequencies, it seems to me, the differences are even less — here and there the midrange is light, with a slight drop at the bottom and a rise at the top. The high frequencies of the Kinera are not bad, but they sound noticeably simpler than those of the TRN (less detail, worse length and accuracy).

Advantages and disadvantages


+ High quality sound.

+ Good ergonomics and sound insulation.

+ The charging case fits even the largest earbuds.

+ Gorgeous autonomy (when using a charging case).

+ Informative indicator of the charge level.

+ Availability of wireless charging.


– Volume control may not work correctly.

– There is no manual on / off function for headphones.

– Quite large dimensions of the charging case.


Even if we take into account the bugs with the volume control, the headphones turned out to be very successful. TRN T300 have high-quality sound, make it possible to use large-sized attachments, as well as provide very good autonomy from the charging case.

That’s all for me. If you have any questions, ask them in the comments below the article. Happy shopping everyone!
