Tronsmart OpenFly 2 Pro Open-Ear Headphones Bluetooth 5.3 40Hr IPX5 Black

Open-Ear Fit for Extended Wear

Tronsmart OpenFly 2 Pro headphones sit outside the ear canal using skin-friendly materials for a secure, lightweight fit. The open-ear design avoids earwax buildup and hearing fatigue while keeping you aware of traffic or announcements during workouts or commutes. Weighing 0.084 lb, they stay comfortable through long sessions without the pressure of in-ear tips.

Sustained Playback and Stable Connection

A single charge provides 10 hours of continuous playback, and the charging case extends total listening time to 40 hours. Bluetooth 5.3 maintains a stable link beyond 10 meters or 33 feet, so audio does not drop when the phone stays in a bag or locker. Recharging the buds takes 1.5 hours and the case reaches full capacity in 2 hours, minimising downtime between long training days.

IPX5 Build and AI Call Clarity

An IPX5 rating protects the internals from sweat and rain during outdoor runs or gym sessions. Four microphones with an AI algorithm isolate your voice from wind and background noise for clear calls in busy environments. The USB-C dongle adds a simple wireless option for devices without native Bluetooth, while the open frame lets ambient sound pass naturally without electronic transparency modes.
