## Description

Product Description Enjoy your HiFi music wireless anywhere with a simple plug Transform your home and car audio system with Firefly LDAC, a powerful Bluetooth music receiver packed in a compact USB size. Certified as High-Res audio, Firefly LDAC streams the highest quality music from your smartphone or tablet via Sony LDAC technology for Android or AAC codec for iOS. Equipped with the latest Bluetooth 5.0 chipset for a stable connection, the Firefly LDAC is the ideal accessory for both iOS and Android users who are looking for the best wireless music quality. Simply plug Firefly LDAC into your audio system and USB power source and start enjoying your music! You can pair your mobile device with Firefly LDAC via the Bluetooth menu Settings. Its LED light glows like a Firefly, so you always know the connection status. Note : If your car does not have a USB port, we recommend using a 5V car adapter from a reputable brand to avoid damaging both your phone and Firefly LDAC. Don't settle for subpar sound quality! Most Bluetooth receivers only support the default low quality SBC codec, which is less than ideal for music streaming. The Firefly LDAC is one of the few receivers on the market that supports Sony LDAC technology that allows streaming high-resolution audio over Bluetooth connections at up to 990 kbps at 32 bit/96 kHz (vs Qualcomm’s aptX at 352 kbps and aptX HD at 576 kbps). *N ote that your Android device will also need to support LDAC (e.g. Android 8.0 or up). Please check with your phone manufacturer for details. iOS devices, as well as a few others, implement AAC over Bluetooth, making the Firefly LDAC a must have for iPhone and iPad users who want to get the most out of their speakers and car audio systems. The TUNAI Firefly LDAC aims to optimize your listening experiencing by also adding a high-performance external audiophile-grade DAC from Cirrus Logic (127dB SNR) which provides superior conversion and more authentic and clearer quality of music. Enjoy an enhanced listening experience that allows you to distinguish different sounds and instruments and notice finer details. Firefly LDAC remembers up to 8 paired devices! It will auto-connect to the last device used as soon as you start your engine or turn on your home audio system. Never worry about forgetting to charge your Bluetooth receiver again! Unlike many Bluetooth receivers on the market that require charging, Firefly LDAC works as soon as you turn on your engine or your home audio system. It is charged directly through the USB port while it plays. Unique ‘party mode’ feature allows TWO devices to be actively connected with Firefly LDAC at the same time so you can play music from either device. Connect both phones and simply start playing – it’s that easy. No disconnection required. TUNAI Connect App offers customized EQ settings, ground loop isolator settings, firmware upgrades and more! It is available on both iOS and Android stores. Note: If you are experiencing issues with Firefly LDAC, make sure to update the firmware via app first as it might solve the issue in a minute for you! Upgrade from the original TUNAI Firefly Bluetooth Receiver Ground loop isolator is now included - no more hissing and humming sound! TUNAI listened to customers and added a ground loop isolator inside of the original Firefly Bluetooth receiver, all without increasing the size! The ground loop isolator inside will eliminate 99% of the hissing and humming noise interference produced by the car. You can simply switch on the setting on TUNAI Connect App and truly enjoy your favorite tunes through just one simple compact device. What's in the box Firefly LDAC Bluetooth Receiver 3.5mm AUX extension cord (60cm / 23.6") Instruction manual Spec Bluetooth 5.0 10m/33ft connecting distance Additional audiophile grade DAC : Cirrus Logic 127dB SNR Audio codec: SBC, AAC, LDAC Built-in ground loop isolator Power supply: 5V USB input Audio output: 3.5mm AUX IMPORTANT NOTE: Please remember to UPDATE THE FIRMWARE FIRST you have any issues, this might solve the problem you have right away. For Android 12 users , Google has made some changes over BLE and you might not be able to connect to our TUNAI connect app. In this case, you can use another mobile device not running Android 12 to update Firefly LDAC to the newest firmware and you will be able to use your Android 12 device with our TUNAI Connect app. How can I improve the sound quality if it seems distorted, especially on loud bass? If the sound is muddy, turn down the volume on your phone, and up on the car stereo. If there is a humming and hissing sound (ground loop noise), turn on the “ground loop noise cancellation” option on TUNAI Connect App. Firefly LDAC is connected but there is no sound, what should I do? As there are two connections that might show up on your Bluetooth list (one for the app and one for the sound), make sure to check on your Bluetooth list and connect to all items showing as “TUNAI FIREFLY LDAC”. Sometimes the Firefly LDAC doesn’t reconnect to the phone or the connection is not stable. What can I do? ‘Forget’ all devices from your phone’s Bluetooth menu, restart the phone, and pair with the Firefly LDAC again. If you are experiencing unstable Bluetooth connection, make sure you update the firmware via TUNAI Connect App. The USB port doesn’t seem able to power the Firefly LDAC. Is there a solution? The Firefly LDAC takes very little power (~20mW), causing some car USB ports to be unable to detect the Firefly LDAC 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. How do I know if my device supports LDAC? How do I know if it is on? Any Android with 8.0 (Oreo) or higher supports the SONY LDAC codec. LDAC usually needs to be manually activated in most cases. Please check your phone user manual for how to turn on LDAC for your model. How does ‘party mode’ (multiple device connection) work? When party mode is turned on, TUNAI Connect App and two devices are connected to Firefly LDAC. Whichever device that starts playing the music or receives audio notifications will become the main output device. When one phone is playing music, we suggest putting the other phone on mute/pause other audio media to avoid disruption. Can I take calls with Firefly LDAC? No - Firefly LDAC does not have a microphone. If you need to take calls, please check out the Firefly Chat LDAC.

Review: This has been a game changer in my Discovery 3 - TL:DR: This is a great piece of kit, with good volume, great sound quality and easy installation. So, one of the major bug bears I have had with my Land Rover Discovery 3 is the lack of Bluetooth (sort of understandable from a car which was made in 2006, but I like complaining...) The car has a 3.5mm aux jack in the rear of the centre console, but, as with all things Land Rover, this comes with its own set of problems... The Aux jack is unamplified, meaning that even with the phone on full wack, you really need to crank the stereo up to full just to get normal volume, and any chances of impressing groups of 'yoof' as I drive past with my favourite late 80s thrash metal blaring out of my window and my sunglasses on are pretty much non-existent... Enter the Firefly... A few Discovery 3 owners had been harping on about how great these things were, but as a cynical member of generation X I was deeply suspicious that it would make any real difference to the pathetic sound output of my car radio... How wrong I was... It was payday, and I'd blown most of my paycheque on cheap beer, but in a haze of hops I thought "I'll just get one of those and see if it's as good as they say it is"... Best drunken decision I ever made... The radio can now crank Anthrax out loud enough that I can see the local young people waving their fists and middle fingers at me as I drive past in what I imagine is the modern day expression of awe, and I can finally make my ears bleed in the way that Sepultura intended! It was really easy to install (Fortunately the D3 has a cigarette lighter socket right next to the aux port, but the car kit comes with an extended aux cable if you need it) and just syncs up to the bluetooth on my phone as soon as I get in, which is a huge improvement on having an aux cable floating around the car and having to fish it out from under my passenger's feet before I set off... Highly recommended!
Review: Genius - crystal clear sound, unobtrusive, and ever ready - I must admit I was a bit sceptical about this, but it hasn't disappointed at all! I have the Firefly permanently plugged into my car 12v charger point, with the aux cable running unobtrusively down the back and it looks great. When i turn on the ignition, it flashes showing it is ready to pair, and when it pairs the solid light shows it is connected and working. It is simple and minimal in its design, which makes it so powerful - please don't be put off by complaints about not having control of audio etc, it really isn't an issue - I use it every day, and I use the term 'set it and forget it' far too much in reviews, but this is exactly what the Firefly is - plug it in, then forget it is there. Like other reviewers I wanted something I did not have to constantly charge or fiddle with and this fits the bill. There are a couple of negatives, neither of which are attributed in any way to the receiver itself. Firstly, the pairing of the aux socket and USB socket in the Hyundai i10 (which I drive) would suggest that this would be the perfect place for its installation (see all the photos in the supporting descriptions); however, when I plug anything into my USB drive it tries to 'read' the USB, and then fails, so disconnecting the USB and rendering the device inoperative. I haven't found a way to change this, so for now my Firefly is plugged into a multiplug on the 12v charger point, which is acceptable but a bit annoying. Secondly, there are (occasionally) connection issues, but I actually mostly attribute these to my tablet (which I play music from, and is a pain in the a**e anyway) and not the receiver. I believe the receiver to be a 'passive' item - i.e. provided it has power it is set up and ready, it has no ability to disconnect itself. Tablets or phones, on the other hand, disconnect from Bluetooth for a myriad of reasons, sometimes unfathomable. I would say 'lost connection' is perhaps a few times in a week, and usually righted fairly quickly. I can drive for hours and not have any connection issues (e.g. drove 6 hours and never a hiccup). I would look carefully at any device first for problems. My only other comment, and this is me being a bit picky, is that the build quality is a bit plastic for such a premium price, but as I don't spend a lot of time handling it, it really doesn't matter. I struggled for years with dodgy aux cables which would break, and the sound quality was never great. Sound quality off the Firefly is crystal clear. I can't recommend it enough.

## Questions & Answers

**Q: How do i get this to work with my 2014 fiat 500? it connects to my phone just fine but when i play anything with audio, there is no sound.**
A: It works perfectly with my Hyundai ix35 and the sound is amazing. If your phone is already connected to your car Bluetooth it takes priority when you start the engine. What I do is just unplug the tunai usb for a second then plug it back in and the sound comes on.

**Q: Is there any audio quality loss ? (Comparing to the aux connection)**
A: none that I have noticed. I have only used it in the car so far so not the best environment for determining sound quality but I can’t fault it.

**Q: Can you plug this straight into your phone?**
A: This device is to wirelessly connect your phone to your car via Bluetooth; the USB and 3.5mm jack both plug into the car - USB powers the Bluetooth unit, the 3.5mm jack inputs the received data into the cars audio system

**Q: Please send the full instrucction manual. It is not on the Tunai website.**
A: I just typed in tunai firefly instructions in Google and its a pdf

### ⭐⭐⭐⭐ Great Device
*by L***S on 2 May 2024*

I purchased this specifically for my BMW Z4 which does not support bluetooth audio, only bluetooth calls so needed a device for streaming music to the infotainment wirelessly. (Positives) Setup was easy and was running within 5 minutes. Audio Quality is fantastic and i would highly recommend this to anyone in need of a lossless, wireless audio receiver. Quick to reconnect when nearby and allows for a multi device party mode. App is simple enough to update device. (Negative) My only gripe with this device is lack of media control through my car steering wheel, given the USB cable i was using allowed for skipping track with my phone, the AUX does not allow this using this device. I expect thats an issue more with the car and make than with the device. As a mid term solution it works for my intended purpose and device functions as expected.
