Bluetooth 5.3 Aux Car Adapter, SONRU Bluetooth Receiver for Car [Dual Connection & Mic Noise Cancellation], Aux Adapter with Plug-and-Play for Music/Hands-Free Calls/Stereo Audio

Would purchase again
Work well. Seems to auto connect every time with no issues.

Impressive noise cancelation, nice sound. I would recommend this and a noise filter.
My nephew has an older car that does not have Bluetooth but does have RCA AUX inputs. I bought this and a noise filter as well as 3.5mm to RCA adapter. It turns out the adapter was not needed as one came with the Bluetooth adapter, despite me not seeing it anywhere in the description details of it. A nice surprise, just wish I had known before ordering my own adapter.The noise filter did come in handy though as there was a hum with an occasional popping noise. I plugged in the noise filter and it sounded great after that.The call audio is nice and clear. When I talked to my nephew, you can definitely tell he is in his car but I could hear him clearly with no background noise. I could also hear his passenger very clearly too.Of course my nephew was most impressed with the sound quality. He was using a Bluetooth to FM device before ad could never get it to sound quite right. He is happy he can play his music loud and clear again.I would recommend for someone in a similar situation, just be sure to get a decent 3.5mm noise filter as well.

Great product for older cars with auxillary jack
With the elimination of headphone ports on cell phones, this adapter is essential for people driving older cars not equipped with bluetooth audio. The setup is seamless and can be used for both streaming music and hands-free phone calls. The size is convenient as it doesn’t take much space on the dashboard or center console. The quality of the audio output is fantastic and the noise cancellation works very well. I highly recommend!

Constant popping and crackling noise
It works.. mostly.It was easy to hook up and connect my device to the car audio. Just plug the mini jack into the AUX port on the car and hook up the USB to power it. It showed up shortly after on the device for pairing.However, that is the best I can say about this unit. The quality of it while it looks nice seems to be extremely poor.The sound quality would also be good IF there was not a constant popping and crackling noise.As such, I can only give this two stars as it does work and is pretty easy to hook up and pair.

Wow. I never expect much from any Bluetooth device as they can be fiddly to set up or just not connect.By contrast, this was a doddle – very easy indeed.Sounds quality is very good to, more than good enough for car use where there’s always road noise in the background. For those people who complain they get interference, I’d suggest one of two things:1) If you’ve a petrol car and you have regular interference, you probably need to replace your spark plug leads, it’s not this unit.2) If the interference is just noise, or breakthrough with other audio, you’ve not followed the instructions. You need to tune it to a frequency that has NO radio stations on it. Bottom or top end frequencies are best in most areas – 88-90MHz, or 100-108MHz. Cities will have loads more interference because there are simply more radio stations on the FM band, and sometimes pirate ones. Likewise, the “clear” frequencies will change with your journey. Best tip: Tune 2 or 3 different, adjacent frequencies so you can easily swap between them.Other than addressing those easy to fix “complaints” (read the manual!), which will happen with ANY device of this type, the sound quality is good, it’s easy to set up, and it’s simple to change between microSD card and Bluetooth. The inclusion of two USB ports is an added bonus.Overall: Decent device, easy to use, and ignore the naysayers who complain about noise.

Ich war lange auf der Suche nach einem passenden FM Transmitter und habe einige ausprobiert. Überzeugen konnte mich bisher keiner. Der SONRU FM Transmitter hat auf Anhieb perfekt funktioniert. Gerät im Zigarettenanzünder angesteckt – der vorgewählte FM Kanal hat sofort gepasst. Mit der Übertragungsqualität von Musik (vom iPhone) bin ich sehr zufrieden. Kein Rauschen und keine Nebengeräusche. Für die Freisprechfunktion habe ich keine Verwendung, da im Auto bereits fix verbaut. Deshalb kann ich diesen Punkt auch nicht bewerten.
