Many newer cars come with Bluetooth audio as standard equipment, but what if your vehicle lacks this ability? Plugging your smartphone in with an auxiliary cable can work, but it’s also less than ideal because the cable can get finicky when you jostle it as you skip to the next track on Spotify. A more elegant solution is the TUNAI Firefly.

This handy little Bluetooth receiver has been available in Taiwan for a number of months already, but now it is expanding into the American market to make it easier for everyone to the music and podcasts they all love in a much more convenient way.

In effect, there are two parts to the Firefly: the 3.5 mm aux connection plugs into the audio input for your car’s stereo system, while the part that looks like a flash drive plugs into a USB port for power. Voila.


The elegance is in its simplicity. Other key features on this Bluetooth 4.0 device include the ability to remember up to 8 devices, auto-reconnecting when you turn your car back on, static noise filtering so you get clean audio throughout, and a “party mode” that lets you connect to two devices at the same time. Of course, you can also use this at home, in addition to in your car.

Pick up the TUNAI Firefly on Amazon for about $35 in a variety of colors and accessory kits. The “Car Pack” comes with a dual USB charger, while the “Home Pack” gets an RCA conversion cable. Video and press release are below.
