Tronsmart OpenFly 2 Pro are open-ear wireless earbuds built for people who want to stay aware of their surroundings without giving up audio. They sit on the ear rather than inside it, and the whole setup is genuinely lightweight enough that you can wear them for hours without noticing. Not a product for audiophiles chasing studio sound, but that's not the point.
Tronsmart OpenFly 2 Pro - Overview
The OpenFly 2 Pro use a 12mm biomaterial diaphragm driver paired with Tronsmart's SoundPulse® technology for better bass response than you'd expect from an open-ear design. The patented abTube Balance Tech channels audio directly toward the ear canal, reducing leakage while keeping ambient sounds fully audible. The earbuds weigh just 8.8g each, connect via Bluetooth 5.3, and carry IPX5 waterproofing for outdoor and sport use. Available in black only.

- Driver: 12mm biomaterial diaphragm with SoundPulse® technology; frequency response 20Hz–20kHz
- Battery: 10 hours per charge, up to 40 hours total with the charging case; 10 minutes of charging gives roughly 3 hours of playback
- Microphones: 4-mic system with AI noise reduction algorithm for call clarity
- Connectivity: Bluetooth 5.3, up to 10m range, SBC and AAC codec support
- Water Resistance: IPX5 rated with nano-coating protecting internal components from sweat and rain
Who is Tronsmart OpenFly 2 Pro for?
These are a solid pick for joggers, cyclists, delivery riders, commuters, or anyone working outdoors who needs to stay alert to traffic and people around them. They also work well for all-day office use if you prefer not to block out your environment. The Tronsmart app (Android and iOS) lets you tweak the EQ and remap touch controls.
Pros and Cons
Comfort is genuinely impressive - the open design means no ear pressure, and most ear shapes fit without eartips. Battery life is strong. On the downside, wind noise during calls is a real issue, as with most open-ear designs. Sound quality is decent for casual listening, podcasts and calls, but not comparable to sealed in-ear earbuds. No ANC is included.
