[Amazon's Choice] FIREFLY - Bluetooth receiver for car (BLACK)

Transform your home or car audio system to Bluetooth wireless with Firefly, the world's tiniest music receiver, and stream crisp, high-quality music from your smartphone or tablet. With its patented technology to support multiple codecs including AAC, the Firefly is the ideal accessory for iOS users.

With a button-less design, connection is quick and simple. Just plug Firefly into your audio system and a USB power source, switch on the Bluetooth setting on your smart device, and pair. The LED light on the USB end will glow like a firefly to indicate connection status. Once paired, Firefly will remember your device and auto-connect whenever you're close by. For extra convenience, Firefly can remember up to 8 paired devices, and Party Mode even allows two simultaneous connections to easily switch between devices.

Note
Some car USB ports and chargers automatically shut off power when current draw falls below a certain threshold. Because the Firefly requires very little power, it may not work with these USB ports. Some Mini Cooper owners in particular have reported that their cars have this auto shut off feature.

In order to transmit audio to a Bluetooth receiver, your smart device chooses a codec supported by the receiver to digitally compress the audio file. Most Bluetooth receivers only support the default low quality SBC codec, which can become quite unbearable for music streaming. The Firefly is one of the few receivers on the market that includes support for the higher sound quality AAC and MP3 codecs through its patented Sound Revitalization Technology.

iOS devices as well as a few others implement AAC over Bluetooth, and hence, the Firefly is a must have for iPhone and iPad users that want to get the most out of their premium speakers / car audio systems. 

NOTE: Firefly will only stream multimedia audio (music, video, apps, etc.), any voice calls will switch back to your phone or another connected Bluetooth device.
