TUNAI Firefly LDAC Bluetooth Receiver: High Resolution Wireless Audio Bluetooth 5.0 Adapter with Audiophile USB DAC 3.5mm AUX for Car/Home Stereo Hi Res Music Streaming; Auto On, No Charging Needed

This Bluetooth receiver is awesome. I've had it for over 3 weeks and here is what I think so far...Pros- great audio quality- no lag- connects fast and turns on every time I start the car- decent priceCons- has disconnected randomly once or twice- crackling nose when the music was quiet (a ground loop isolator fixed this)- calls doesn't work, have to use speaker phone (not a big deal to me)- the biggest con is that the app isn't available for Android 14, so I can't update the firmware (although I haven't had issues other than connectivity once in a while)Overall works great, sounds great, and is a great alternative to a new head unit.

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.

My car is a few years old and although it does allow a connection to my cell phone via Bluetooth for voice calls, I cannot connect my cell via Bluetooth for other audio (e.g. Pandora, Spotify, YouTube etc.) With a USB port and an AUX port located immediately next to one another in my car's armrest, by simply plugging in one end of the tiny device into each port and pairing the device to my cell for audio I can play music from any music app on my phone and the audio from YouTube videos, for example, through my car's sound system. It easily fits in the very confined space in my car's armrest. Once the device is paired with your car's Bluetooth, all you have to do is enable Bluetooth on your phone, make sure the device is "connected" and you're done. In my BMW, the device continues to play music even after you turn off your car. (I'm not sure how it will work in other vehicles.) I've been using the device regularly for many months without any issues. Relatively inexpensive and absolutely worth every penny I paid. NOTA BENE: Although it may be obvious, the device does NOT require a battery to operate. Although you will need a spare USB port for power for the device to function, this feature dispenses with the need to constantly replace or recharge batteries, a huge convenience in longer road trips.

I've been using this for over a year. In short, it's great! Excellent sound quality. My phone connects nearly immediately after I turn my car on, and my phone doesn't stay connected when I turn the car off (because unlike some competitors, the Firefly doesn't have a battery). It also has no switches or buttons to mess with--something I don't want or need. This is literally the perfect fit for my use case. It has also proven to be reasonably durable since it has lasted for at least a year of use so far.I use it with...- A 160W USB C Car Charger, Baseus Type C Car Charger. The three ports of this car charger are used for:-- (USB A 30W) This Tunai Firefly-- (USB C 100W) An OhSnap! Snap Charge (To wirelessly charge my phone. There are newer versions of this like the Qi2, but I'm using an original Snap Charge.)-- (USB C 30W) A USB C to lighting charge cable for my passenger's older iPhone.Other info about my step, if you're trying to replicate it:- Car: Honda Element- OhSnap! Snap Car Mount (To hold my phone so I can have it serve as my GPS & music player.)- OhSnap! Grip on the back of my phone. (For a secure connection to the Snap Car.)A word of warning:I tried using the Tunai Firefly with an Anker Compact Fast Car Charger 3 Ports 67W BUT when devices were plugged in the other ports (the USB C ones) the USB A port would not provide enough power to turn on the Firefly. I usually love Anker products, but in this case the Anker charger just wasn't the right tool for the job. If you're like me and want to power 3 USB devices with your car charger, the BaseUS version is a better fit for that use case.
