It was very convenient in the car. The source has a 3.5mm AUX IN, I also plug the USB into the source's USB port (for power only - not for data), and thus the source also gained bluetooth. Satisfactory performance.

it needs power supply to work
with a powerbank you can get the job done
it's just that for me after a while it makes interference and an annoying buzzing noise

It disconnects all the time and generally has trouble even connecting (the device I connect daily). By far the equivalent from Ugreen is better

It recognizes it right away, very good product. It doesn't make any static noise at all. The only good thing is that it has a microphone and if you are far away, they don't hear you perfectly. Of course, if you have wireless headphones connected at the same time, the microphone transfers to the headphone and there is no problem.

For music, it's just fine. For hands-free calls with the phone, your voice sounds doubled to the people on the other end.

Excellent product, I have been using it for 2 years, it does its job as it says, I have not had any disconnections, sound quality is fantastic, as if it connects directly to the source without any intermediary.

Very good, quick connection and good sound quality. Perfect solution for the car audio system that doesn't have Bluetooth. The microphone is not good for calls, it doesn't sound clear.

This little thing really freed me up for use with electronic drums where I can now play songs directly from my phone without needing to download them from the internet and convert them to WAV. Definitely a value for money purchase!

It loses the 5 stars only because of the noise it makes when it's not playing. This may vary depending on the power noise, I haven't tried it with a power bank yet to see the difference. Other than that, everything is good, it does play in stereo (be careful because the previous adapter I bought was supposed to be stereo but ended up playing in mono) and it connects effortlessly (it didn't even ask for a code on my phone).

It does its job very well. Before, I had the other company with the most reviews, but in my calls they complained that they could hear me in the background, so I had to shout. Now with this, the complaints stopped and I stopped yelling.

Very good product, you need to have an aux port in your car and a usb port which can also be found with an adapter for the cigarette lighter. (Get an adapter with 2 ports so you can also charge your phone)
The sound is very good - always for aux standards, where by definition you lose a bit of volume and quality.
For hands-free calls it's ok to say a few words, but not for longer conversations!
Finally, for those who don't always have their phone's bluetooth on, it's annoying that if it doesn't connect within the first 2 minutes after you start the car, it automatically turns off and you have to unplug and replug the usb to activate it again.

I have had it for about 1 month. The connection is immediate (as soon as the car gets power). It is worth its money

very cheap, works with all mobile phones and has good sound quality. I have had it for a year and it has not presented any problems so far

After 5 years, the Renault Clio IV stubbornly refuses to connect via Bluetooth. The only solution was to connect the car's screen to the mobile phone with a 3.5mm cable, which I simply got used to and don't mind doing. Skroutz randomly suggested this product to me when I was placing an order, it's cheap so I thought I'd give it a try. Well, in the end, the product is fantastic, instant connection, no interruptions - PERFECT. The only downside is that I don't have the steering wheel controls for pause/next, but now I do those from my Smartwatch.

Very good, it connects instantly to the mobile phone. In calls, the sound and microphone are impeccable, but in a car with an amplifier where even the slightest flaw can be heard, it produces minimal interference that can only be heard in between songs where there is no other sound... otherwise perfect..!

Very good! It does exactly what it says without any problems and with perfect sound quality. The only thing that didn't impress me is the quality of the cable, which will definitely break with improper use. But personally, I will have it permanently in the car, so it's unlikely to get damaged.

Perfectly terrible sound quality... not worth it... and not at all well-made, the cable will break soon... in terms of connectivity, it's fine.

Useless, no mobile phone detects it, only ugreen does, same accessory and does what it promises, too bad for Baseus which is considered a reputable brand

The cable is very good. It connects immediately and with more than one device at the same time. Its construction is excellent. I use it every day. I highly recommend it.

It is incredible in terms of construction quality, simply a jewel !!! The sound is exceptional and it connects directly to the iPhone XS. Bravo to the manufacturers !!!

Finally, I have hands-free in the car! Very good, easy to connect, elegant, very good performance both in sound reproduction on the speakers and in calls, and at a very good price! I highly recommend it!

Perfect receiver to convert your car's old aux in to Bluetooth. As a microphone, if they will hear you without having to shout, it depends on how low the car's console is, but still, it does its job very well.

It does not automatically connect every time if you have the air conditioning on, it does not hear you no matter how loud you shout. Unfortunately, it is not that good

Awesome for its price. It doesn't lose at all.

tip: don't connect it to the lighter if you have a USB in your car audio, as it has a few glitches with the lighter if you increase the volume.

The product is excellent, it connects to the radio-CD's USB and I connected it directly to the aux and they hear me perfectly, also the sound quality was excellent. Recommended. Update: after so many years it remains at the same quality, you can't get more recommended for such a VFM product.
Update end of 2025, after so many years still reliable, it just disconnects much more easily than before when I don't use it continuously and I have to turn Bluetooth on and off on the phone while driving, which is dangerous. I might buy the slightly more expensive model.

Excellent solution for those who want audio streaming via Bluetooth and/or Bluetooth hands-free in the car. The device receives power without any problem from the standalone USB ports of the stereo or the car's USB port. I have tried it on a Pioneer system from the 10s and on Blue&Me systems of FIAT without any issues. Of course, a 3.5mm jack is needed to provide sound to the AUX. Very good in terms of sound performance as well. The only thing that slightly concerns me is how durable the cable will be. I would definitely buy it again.

For the product: it is Bluetooth, one side needs to be plugged into a USB port, so you put it in the car's cigarette lighter in the USB slot and you place the other part in the aux port. Then on your mobile, you find the product in Bluetooth, connect, and everything is ready. Very good quality, no problems, no static in the sound.

The best I have ever used. Very good performance. The sound from the car speakers is crystal clear. Also, they hear me very well. It needs to draw power through USB from the cigarette lighter.
