TUNAI Firefly Bluetooth Receiver: World’s Smallest USB Wireless Audio Bluetooth 4.2 Adapter with 3.5mm AUX for Car/Home Stereo Music Streaming; Auto On, No Charging Needed - Premium Pack (Black)

The product is fine and works well with Denon avr. The only issue was I had to buy additional audio cable as the supplied cable has only one audio for aux. So take care on this issue before buying.

Works as advertised

Suddenly stopped working, used it less than a year

I use Alexa show already for years in my place, living room and bed room. Easy and comfortable and control heaters, lights, alarms and camera's with it. Great stuff so the next step was to have one in my Discovery as I travel a lot and several times to countries in Europe.A bit disappointed about the information Amazon is giving about the computability with phones and cars as the Land rover Discovery III is not on that list so I thought it should be ok but it wasn't. The radio cannot be connected for audio streaming via Bluetooth, only for handsfree use of the mobile phone which works excellent.Spending some hours on the internet and found the best solution would be the LRBT-1 from an American country but they run out of them but after an email when they would be available again was answered within several minutes and telling me that they would be available in August again. Good news but as I have a trip scheduled in August for France, Belgium, Holland and Germany I wanted an interim solution which I also found to be acceptable.TUNAI Firefly Bluetooth Receiver with an AUKEY Car Charger with dual ports ordered via Amazon and received in 2 days so a quick install and test worked out it is an excellent interim solution until the LRBT-1 is there which is a retrofit for the Land Rover Discovery III.Now the Alexa in the car works as I want it, and a simple connect to my iPhone via BT gives excellent results.Finding a good place in the car was also important so the best option was to have it mounted on a spare Roof light unit I had purchased for £20.= was the best option so the passengers in the front and in the back can also use it easily.I'm happy with it but would like Amazon to pay more attention to additional information about the compatibility with cars and phones including alternative solutions. That is for me the reason to give only 3 stars.

It is almost unfathomable how good something this small actually is. I hard wired a new USB power socket behind the dash and fed this into the back of my 2007 Mazda MX5 stereo via a link lead, so all is invisible (all wrapped in bubblewrap to prevent rattles), and within 30 seconds of finishing the installation was listening to music via Bluetooth.I wasn't expecting this to be that good, but it is exceptional. I can even walk back to close the garage doors with my iPhone in my pocket and it doesn't drop the signal. The sound quality is indistinguishable from the old Aux cable connection. When I come back to the car the next day, my phone finds the connection again. This is brilliant.This is such a tiny thing, but it is exceptionally good and has brought my car bang up to date. I cannot stress too much how impressive this thing is.The best thing I've bought this year and I would recommend it to anyone.I was at one time even considering changing the car audio unit to get a Bluetooth connection, but I'm glad I didn't.I shall now be buying more for the stereo at home and the speakers in my office so I can stream music from my laptop.This device changes everything.

Purchased this for my BMW (2011), which only allows you to Bluetooth a mobile phone for calls. This TUNAI Firefly solved all of my issues with listening to my music in the car without ugly aux cables poking out of the centre-console. Easy to connect, and paired devices will automatically connect when ignition is turned on. Have recommended to friends who have the same issue as me, and they're not disappointed.

I don’t usually leave reviews but I am really disappointed with this. For £30 I expected a decent bit of kit. It is so temperamental and doesn’t work full stop on the small aux lead, so I constantly have the long lead plugged in which defeats the point of it looking tidy in my car when the aux and USB ports are right next to one another! More days that not it doesn’t work. It’s a nightmare to connect via Bluetooth and considering my phone works with the car’s phone Bluetooth system, it’s not my phone that’s the problem.When I spoke to their support team, they asked me a bunch of questions and ignored my answers concluding my problem was down to something we had already ruled out it could be. They clearly have a handbook of suggestions to give out for any unhappy customers and weren’t willing to listen to what problems I was actually having!Such a waste of money.

Bought this for my car in order to play tunes from my phone via Bluetooth. Great product, but there's a problem with what sounds like an intermittent loss of BT connection. It's very sparodic and the silence only lasts a second or so, but slightly irritating nonetheless. The phone is never more than a metre from the receiver either.
