Disclaimer:
Hello Readers, Today we are here to review the new TWS from Tronsmart. The Tronsmart OpenFly 2 Pro are TWS headphones designed for use in traffic; in fact, they aim for maximum transparency of the sounds that surround us. They are not the type of product that I would define as audiophile since the technical solution adopted does not aim for maximum audio quality but for maximum versatility.
However, the review will still be 100% honest and in no way biased.
I’m not an audiophile; I’m just a guy that likes to test out different IEMs and DACs and spends a lot of time listening to music.
So I’m not going to use super-technical words to review it, but I will do my best to describe it.

Packaging:
The packages of the Tronsmart brand are always made of very rigid cardboard; the quality and care of the packaging already make you understand that the product contained is of good quality. Inside, we have fewer things than usual.

Since there is no nozzle of any kind, there are no eartips, and the product comes without extra accessories.
Design/Build Quality:
The Tronsmart Open Fly 2 Pro does not have a particularly new design; we can say that this type of product is not new. There are many of them of all brands and the design is more or less always identical. The case is very flat but slightly wider than usual and very comfortable to put in your pocket. The only technical information is on the inside. Except for the logo on the top, there are no other external acronyms. On the back of the case, we find a type-C port. Opening the case, we find the Tronsmart OpenFly 2 Pro.
The case has several LEDs, an external one that indicates, on the front, the charging status, and internally, next to the TWS, it has two white luminous commas. The two earphones also have a small white LED.
The earbuds have a very minimal look, plastic and silicone. They have several holes on the body that I think could be the microphones plus the driver ventilation system (which we will talk about later).
The quality to the touch and the finishing seem excellent to me; I think they are quite resistant.
Tronsmart App:
There are no alien technologies but they have an accompanying app. The Tronsmart app allows you to manage, above all, the equalizer. I personally created a personalized EQ, managed any firmware updates and, above all, modified the controls as you like. There are no special features regarding these earbuds. The only hardware technology present is called “abTube™ Balance Tech: Precise channels sound into your ear canal, minimizing audio leakage and enhancing bass.”
There is not much information about it but in fact the sound is quite targeted to the ear canal and the bass, even if a little strange, is present.
Fit & Comfort:
The Tronsmart OpenFly 2 Pro is the end of the game. In terms of fit and comfort, there are no rivals. You don’t need to have eartips; small or large ears fit on all ears. They are made in such a way as not to cause any pressure points; in fact, it seems like you are not wearing them. They are ideal for those who use them in traffic, such as delivery guys, as well as those who enjoy outside sports and want to stay in touch with their surroundings. If the volume is not super high, you can hear any ambient noise. I am part of the category that cannot use the TWS in traffic or walking on the street. I can’t stay calm without hearing the noises that are there. With the Tronsmart OpenFly 2 Pro, you can easily listen to a person who is talking to you while listening to music.
Phone calls:
The Achilles heel of all these products is always linked to the wind and the ability of the microphones to handle strong ambient noise. Since there is no ANC mode, noise suppression is not present. In case of strong wind or when using a bicycle, the turbulence does not allow clear audio. This is a problem that 90% of the TWS on the market have. The only one so far that has managed to suppress wind noise was the Roseselsa EarFree i5. Back to us, the call quality is good.
Equipment used for the testing:
Device:
- Poco M4 Pro (AAC)
Software:
- Amazon music UHD 24bit 96kHz
Sound impressions:
The Tronsmart OpenFly 2 Pro is not a product that aims for high fidelity but for high transparency of the noises around us. Instead of ANC, we have the ear that is free to hear external noises. Obviously there is sound dispersion, or rather a type of sound that is closer to old-school earbuds. They sound strange, a little unusual compared to what one expects. The bass, especially sometimes, seems to come from a passive radiator that makes the air vibrate. Overall, a clean sound for the type, but I haven’t tried any other similar products. I wouldn’t use them for rock or drum & bass because they get muddy in complex tracks.
After equalizing a bit on the highs and lows, the sound is slightly better in my opinion. The stock equalization pushes a lot on the mids. But as you will notice yourself if you buy them, the positioning of the same and the conformity of the ears can lead to different results. In fact, if we change the angle or push the earbuds slightly towards the ear canal, you will feel a monstrous increase in bass. At maximum volume, the bass is tangible on the body of the OpenFly 2 Pro. The driver, in my opinion, is of very good quality but it does what it can in these shells and structures.
Treble
The trebles are sometimes not super clean and sometimes a bit harsh but I gave a boost to add detail and brightness to a not-too-pushed extension. Overall the details are good, even if macro and micro details must be searched with more attention.
Mids
They focus a lot on the mids; in fact, stock has a predominance of the voices that are not even too unreal but quite coherent. The instruments are also good. But as reiterated from the beginning, they are TWS designed for mobility.
Bass
The bass gradually increases to 70% of the volume, after which the volume only increases the trebles. Listening to them vaguely reminds me of the bass coming from a passive radiator (especially in some tracks). The emphasis pushes a lot on the resonance factor and the result is passable. Do not expect deep and thick bass.
Soundstage & Imaging:
The sound is quite intimate and flat; there is a feeling of air but the soundstage is still limited. The imaging is good as long as the tracks are not too complex. Depending on how it rests on the ear, you will have a better performance. Correct positioning is essential.
Conclusion:
My conclusion is that the Tronsmart OpenFly 2 Pro is a product with a specific target audience. It is certainly not a product for those looking for Hi-Fi quality but a useful accessory for those who work or do something outdoors. A comparison with standard TWS would make no sense since, in terms of audio performance, it would be easy to give better. For its purpose, they are the best wireless earbuds I have used in city traffic and probably the only ones I would use to preserve my safety.
