FAQ

  • How can I improve the sound quality if it seems distorted (muddy or staticy), especially on loud bass?

Turn down the volume on your phone, and up on the car stereo. This should improve the sound.

  • I hear a noise when no music is playing, like a whine or hum. Is there a solution?

This is caused by a ground loop in the car’s electrical system. Please contact TUNAI for help, or use a ground loop isolator to suppress the sound.

Warning:

In some car electrical designs, using a ground loop isolator may cause no sound output. Please contact TUNAI for help.

  • Does the product require a power source?

Yes, the product requires power. Please use your car’s USB port to provide DC 5V. If your car does not have a USB port for power, you will need to prepare a car charger or similar device to supply power.

  • Sometimes the Firefly doesn’t reconnect to the phone. What can I do?

‘Forget’ all devices from your phone’s Bluetooth menu, restart the phone, and pair with the Firefly again. If you’re still having trouble, please contact TUNAI.

  • The USB port doesn’t seem able to power the Firefly. Is there a solution?

The Firefly takes very little power (~20mW), causing some car USB ports to be unable to detect the Firefly and shut off power. Select models of Mini Cooper and BMW are known to have this issue. Switching to a USB cigarette adapter will solve the problem.

  • Can I take calls with Firefly?

No. If you need to take calls, please check out the Firefly Chat.

Used with a mini amp ORB Audio BOOSTER this allows you to stream without turning on the TV. Can watch video on phone but still have stereo sound. Great range, rarely have connection issues

Good product and does as described. Easy to use and no need to worry about the battery life as it’s just plug and go!

Decent price, and very simple to use. It’s minimalistic as well; Nothing clunking around in your glovebox or console while you drive. I like the idea of the Firefly a lot! Only problem is that the sound quality…it’s no good. Even with the stock sound system in my 2010 135i, there’s a very substantial decrease in sound quality over a conventional wired connection. I know I shouldn’t expect it to be perfect, but this just doesn’t perform quite as well as other wireless alternatives. If that were improved, I’d buy another just to experience it. It really is a neat product, I just wish the sound were better.

It’s super convenient for the car but it sounds like AM radio. Would have returned it if I didn’t wait too long.Seriously it’s rough, get something else.

All in the title. This item insists it has ground loop isolation but it does not. Plugged it in the car and it emits an awful whine audible over everything. It’s going back.

Bought 2. Worked perfectly on a 2011 Honda Element. Breeze to setup and sounds good. Doesn't work on a 2016 Wrangler with stock radio. Right side speakers play but nothing from left side. Swapped unit from Element with different cable and same issue. Radio works fine with aux cable to phone so it's a Firefly issue.
