WHAT'S HOT The wave of Bluetooth headsets work great with your smartphone or tablet, but connecting them to wired headphone ports is impossible. That's what almost every airline has installed for in-flight entertainment. Now you can connect the tiny AirFly to the 3.5-mm wired headphone jack with the included audio cable and pair it wirelessly to your handheld devices via Bluetooth.

It works great with wireless earbuds, headphones and true wireless earbuds.

While it works well at 36,000 feet, there are still ways you can use it on the ground, such as using a wireless headset with a TV. Also, it's now a breeze to connect to audio systems at a gym  and keep yourself from being tethered to a workout machine with an audio cable.

A built-in USB-rechargeable battery will last for about eight hours and works indefinitely if you have it plugged into a power source while in use. Besides the microUSB charging port and the 3.5-mm audio connection, there's a single button is for pairing.

To pair, press the button on the AirFly for a few seconds and the pairing button on your headphones. There's no display, app or anything to show that the connection is made, it just works. After the first time it's paired with your device, a connection is made whenever the AirFly is turned on and in range of your headphones.

A travel pouch is included.

WHAT'S NOT While not exorbitant, it is a tad pricey.
