As we mentioned earlier, the Tronsmart Bang SE is the smallest speaker in its family, measuring 298 x 164.5 x 118.8mm and weighing 2.5 kilos. Naturally, the speaker has a cylindrical plastic body and consists of a fully integrated handle with attachment points at each end for the included carrying strap, which allows you to sling the speaker over your shoulder.

In another vein, the audio emanations are created using a Class D amplifier driving two 3.93-inch full-range drivers, enhanced by passive radiators at each end. RGB lights adorn both the speakers and radiators. But unlike the standard and Mini model, the Bang SE doesn’t have separate woofers and tweeters.

With that said, at the top of the speaker we find the multi-function controls, which break down as follows: Power/Bluetooth pairing, SoundPulse EQ, volume down, play/pause, volume up, TWS (wireless stereo), and show. lights on/off. It should be noted that This last button also serves to change the various RGB patterns of the speaker.

A large rubber seal at the bottom rear of the unit covers all the ports on this speaker and helps you get a IPX6 certification grade. The latter means that it is waterproof, but not to the point of being able to submerge, only to resist splashes and humid environments.

sound and features

We are facing a device that provides a 40W full power hand in hand with two front-facing full-range speakers. In addition, it has 3 passive radiators and boasts the SoundPulse technology from the company, which basically reinforces the bass in terms of quality.

With that in mind, the Tronsmart Bang SE sounds great for the money. treble is decent and the midrange is reasonably defined, if a bit muddy. The bass is pronounced enough for most music genres. However, the reproduction of subwoofers leaves something to be desired, because, although can be heard in the 50 to 60 Hz rangewhen it is below that it tends to disappear.

As you’d expect, it’s a directional speaker, but there’s minimal stereo separation between the dual speakers.

It is worth mentioning that there two Soundpulse EQ settings. One is a fairly flat frequency rolloff, while the other brings out the lows and highs with a slight scoop in the midrange.

Tronsmart Bang SE - Stereo

In terms of volume it’s a great speaker, sounds pretty loud and clear without distorting at medium volumebut unfortunately it is not the same at maximum volume, where distortions and sound artifacts can be perceived.

Another aspect that we have to seriously criticize is the lack of a companion application to tune the sound to our liking and access other features. It is curious (and very disappointing) that this is the only speaker in his family that is not compatible with the Tronsmart app, so we have to subtract a few from his final assessment.

For even better sound we can combine two Tronsmart Bang SE speakers wirelesslyresulting in true stereo sound.


Turning the speaker over we find a port usb-a to charge other devices, a USB-C port to charge the unit, a 3.5mm auxiliary inputand a microSD card slot (labeled TF for TransFlash).

Tronsmart Bang SE - Connectivity

At the wireless level, it obviously uses Bluetooth (5.3) to establish connection with our mobile, computer or device on duty. The great advantage of being a Tronsmart speaker is being able to link to a second wireless speaker (of the same model) in order to provide higher power true stereo sound. Additionally, it is compatible with voice assistants such as Google Assistant, Siri and Cortana.


The Tronsmart Bang SE is powered by a 4,000mAh battery that, according to the manufacturer, offers up to 24 hours of autonomy, but that’s with the volume set to half and the RGB lights turned off. If we decide to turn on the lights, then that projection drops to 16 hours. Similarly, we can expect less usage time as we increase the volume above 50%, but it is still a commendable duration for the price of this speaker.

It should be noted that the recharging process takes about 5 hoursas well as the fact that the speaker can act as a Power Bank to charge our portable devices.
