AirFly Pro 2 Bluetooth 5.3 adapter

The AirFly Pro 2 TS-2411 turns any 3.5mm auxiliary jack into a Bluetooth 5.3 transmitter or receiver. It lets you stream audio from airplane screens, gym machines, car stereos or gaming consoles to wireless headphones. Dual pairing supports two headsets at once for shared listening. It is built for travellers and commuters who want cable-free audio from legacy ports.

Over 25 hours battery life and low latency

The internal battery delivers over 25 hours of continuous playback on a single charge. Bluetooth 5.3 with aptX HD Adaptive keeps the connection stable and reduces audio delay for movies and gaming. Quick-access buttons handle volume and mute without reaching for the source device. Regular monthly use of 30 to 60 minutes helps maintain battery health.

Compact 0.2 pound design

Weighing 0.2 pounds, the unit slips into a pocket or bag without adding bulk. Separate pairing buttons for each headphone slot simplify adding a second listener. A mode switch toggles between transmit and receive so you can send audio to headphones or pull music from a phone into a car AUX input. Store at roughly 50 percent charge if unused for long periods.
