Must Have For Non-Bluetooth Cars!
This was my first purchase after I picked up a used 2013 BMW. It was super easy to install and works seamlessly to allow me to stream music in my car. All you need to do is plug it in, download the app, pair it, and away you go! It automatically pairs to my phone when I start my car, so there is no need to manually pair each time I want to use it. The audio quality is fantastic, I don't notice any difference between it and when I plug directly into the AUX or listen to the radio. I am extremely satisfied with my purchase and recommend it to anyone who wants to add Bluetooth streaming capabilities to their vehicle.

Perfect BT audio solution for Fiat 500 and similar
FIREFLY SHOULD BE STANDARD ISSUE WITH EVERY FIAT 500. I love when a product works right and as hoped. A small pet peeve of mine, since buying my Fiat 500 (which I otherwise love), has been the inability to connect media via Bluetooth... Until now! Well hidden in the glovebox, it works flawlessly, like BT is supposed to work with every new car. This should be standard equipment with every Fiat 500 and similar stereos that allow BT connection for phone calls but not media (music, gps, etc.). Be aware that this product derives all is power from the usb port and does not hold a charge at all. Other products have a rechargable battery and an on/off switch, in my case requiring opening the glovebox each time to turn the little unit on, very annoying and not very "oem"-like. Setup took literally seconds, a complete no brainer. The Firefly turns on/off with the ignition and automatically connects. It ONLY uses the media protocal, my car only connects to the phone protocal, so they start up and work simultaneously. You don't have to do anything, just start the car and both are connected. Make phone calls through the car like normal, play music or gps (Google) map directions like normal, everything comes through the stereo controls like the car and BT integration are meant to work. The previous unit I mentioned above was less money, but had wires and the need to switch it on/off was unnecessarily annoying. The Firefly is sleek, discreet and works with the cars BT exactly the way it should. All this wouldn't mean anything if the sound quality suffered. But I couldn't be more pleased, I think the sound quality is exceptional, highs are high and lows are low the way they should be. I do not have any of the distortion or electrical humming that I've read in other reviews. But it is critical that the 3.5mm Jack is fully inserted into the input or this is a common problem with every stereo system. This review written by a very ordinary person, that paid full price for the product but was very satisfied. Hope this review helps fellow Fiat 500 owners.

Sound Quality is great.
Everything is good. Only critique i got is that when the UI for the app can be abit buggy. Not a big deal as its still really simple. Sound quality is great. Multi device bluetooth works fantastic. Chances are if you're buying this device you'll figure it out easy pz. Good build quality. You can turn of the LED's which i have I used mine to turn a set of logitech speakers into bluetooth speakers. Now i can play to my speakers through my laptop, phone and google nest mini. The latency is little to none; you have to REALLY focus to see its less than 10ms for sure. Better than most bluetooth headsets. You can watch dialogue with no problem. I will recommend this device. :D not often do you come across devices which work basically perfectly hence why im leaving this review.

Connects great with Porsche PCM 3.0 and Android
Porsche 997.2 using Android. Did my research beforehand, so knew what I was getting. Can't believe I was living without this for so long. Bluetooth enables Waze, Spotify to connect onto car speakers. Car phone still integrates as usual with speakers, and stops music when call comes in. Perfect. Only complaint is that sometimes, the car phone bluetooth doesn't always automatically connect when using the Tunai. Easily fixed by doing a manual connection, but aside from that, works perfectly. Saved $3k by not getting a new head unit.
