Tronsmart OpenFly 2 Pro Review – Comfortable and practical
Today we’re looking at the Tronsmart OpenFly 2 Pro, a special type of TWS earbuds made for outdoor and traffic use. These are not for deep bass or studio sound. Instead, they are designed to let you hear both your music and the world around you. That makes them ideal for delivery workers, joggers, cyclists, and anyone who needs to stay aware.
This review is fully honest and based on real use.
Unboxing
The Tronsmart OpenFly 2 Pro comes in a solid box made of thick cardboard, giving a strong first impression. The box uses Tronsmart’s signature colours—blue and white. On the front, you can see a picture of the earbuds. The back side shows the earbuds with the charging case, along with Tronsmart branding and basic product information.

A closer look
The Tronsmart OpenFly 2 Pro comes in a simple and slim design that feels light and easy to carry. The earbuds weigh just 8.8 grams each and measure 1.34×2.05×0.62 inches, making them very comfortable even during long use. The charging case weighs 74.5 grams and its size is 76.3×61.5×25 mm, so it fits nicely in most pockets or bags.
Tronsmart OpenFly 2 Pro is available in only one colour—black. There are no other colour options. The case is flat and slightly wider than usual, but still very pocket-friendly. It has a USB-C charging port at the back, and LED lights both on the outside and inside—one light shows the charging status on the front, and two small white LEDs glow near the earbuds when placed inside.
The case has Tronsmart branding on the front, and when you open the lid, the inside top cover shows basic product details like the model and specs. The earbuds rest neatly in shape-moulded slots, and a small plastic strip under them helps stop the charging prongs from touching, which protects against battery drain during shipping.
The earbuds are made from plastic and silicone, and they have a smooth, minimal finish. Several small holes are present, likely for microphones and air flow. The build feels solid, and everything is well-finished for this price range.

User Experience
The Tronsmart OpenFly 2 Pro earbuds are all about comfort. They don’t go deep inside your ears, and they don’t cause pressure. Whether your ears are small or large, they fit easily. You almost forget they’re there.
Perfect for outdoor work, jogging, or cycling—you can hear your surroundings while listening to music. You can even talk to someone while music plays at a low volume.
Sound and calls
These are not made for deep sound lovers. But the sound is clear and good enough for outdoors. Voices are strong, mids are present, and bass is there but not strong.
Calls:
Microphone quality is okay. In quiet places, calls sound fine. But wind is a problem. Like most open-ear TWS, wind noise is hard to control. There’s no ANC, so you’ll hear the outside world clearly—both the good and bad parts.
Sound quality:
The mids are strong out of the box. The highs and bass can be tuned a bit with the app. If you push the earbuds closer to your ears, the bass improves. But don’t expect deep sub-bass. The sound is like classic wired earbuds—clear but with limited depth.
Treble:
Treble is a bit sharp sometimes but adds needed detail.
Mids:
Vocals and instruments sound nice and natural. Great for podcasts.
Bass:
Bass improves with higher volume, but it’s not deep or punchy. It feels more like soft vibration.
Soundstage & Imaging:
The sound feels close and narrow. Not very wide. Imaging is decent unless the music is too busy. Ear position affects sound a lot.
Tronsmart App
The Tronsmart OpenFly 2 Pro can be used with the Tronsmart app. The app is free and works on both Android and iPhone. It is easy to use. You can change the sound using the EQ settings. This helps if you want more bass or brighter sound.
The app also shows the battery level of both earbuds. You can check for firmware updates too. These updates can fix bugs or improve how the earbuds work. The app is simple but useful. It gives you more control over the earbuds.
Battery
The battery life of the Tronsmart OpenFly 2 Pro is really good. On a full charge, the earbuds can last up to 10 hours without needing the case. With the charging case, you can get a total of around 40 hours, which means you won’t need to charge them often. Charging time is also quick. The earbuds take about 1.5 hours to fully charge, and the case takes around 2 hours. This makes them great for people who use them daily and don’t want to worry about charging all the time.
Tronsmart OpenFly 2 Pro – Final verdict
After using the Tronsmart OpenFly 2 Pro for several days, I can say these earbuds are not made for music lovers who want deep bass or rich detail. But that’s not what they’re for. These are made for people who move around a lot—delivery riders, joggers, or anyone who needs to stay alert while listening to music or taking calls.
The open-ear design works really well. You can clearly hear what’s going on around you without removing the earbuds. They’re super light, very comfortable, and you almost forget you’re wearing them. That’s rare.
The sound is clear, especially in the mids. The bass is soft and the treble can be a bit sharp at times, but it’s good enough for calls, podcasts, and casual music. Wind noise during calls is still a weak point, but that’s a common issue with open designs.
Battery life is strong, the build is solid, and the app support is a bonus. No colour options might disappoint some people, but the clean black finish looks nice.
In short, the OpenFly 2 Pro is not for everyone—but if you want safe, comfy, and easy-to-use earbuds for outdoor life, they’re one of the best I’ve tried. For city traffic and staying aware, they just make sense.
