JOINUS Bluetooth 5.0 Adapter 3.5mm Jack Aux Dongle, 2-in-1 Wireless Transmitter/Receiver for TV Audio, Projector, PC, Headphone, Car, Speaker, Boats or in Gym, Home

Work but sometime has a hissing sound when connected to power cable.

Dislike that volume output is limited or lower than another cheaper unit. Also there seems to be a few seconds of latency to start outputting sound (start hearing podcasts slightly past the start)and no audible confirmation that it has connected to my phone. Only used very briefly, it did work though. Maybe it would be better for headphones than for a car aux in application..?

I recently purchased the Car Bluetooth Jack and I am beyond impressed with its performance. Before buying this product, I had been struggling to connect my phone to my car's speakers, and the wired connection was frustrating and inconvenient. However, since I started using the Car Bluetooth Jack, streaming music in my car has become incredibly easy and enjoyable.The setup process was a breeze. I simply plugged the device into my car's auxiliary input jack and then paired it with my phone using Bluetooth. It took me less than a minute to complete the setup and start streaming music. The device is compatible with both iOS and Android devices, which made it a perfect fit for me, as I use an iPhone.The sound quality of the Car Bluetooth Jack is absolutely phenomenal. I was a bit skeptical about whether the sound quality would be good enough to replace my wired connection, but I was pleasantly surprised. The music sounds crisp, clear, and full-bodied, and there is no annoying static or background noise.One of the most impressive things about the Car Bluetooth Jack is how reliable it is. I have not experienced any dropouts or interruptions since I started using it. It seamlessly connects to my phone every time I get in the car, and I don't have to worry about disconnecting and reconnecting every time I get a phone call or a notification.The device is incredibly compact and easy to take on the go. It's small enough to fit in my pocket, which makes it easy to bring with me when I'm traveling. The battery life is also excellent. I can use it for hours without having to recharge it.Overall, I highly recommend the Car Bluetooth Jack to anyone looking for an affordable and reliable way to stream music in their car. It's a fantastic product that has exceeded my expectations, and I'm sure it will do the same for you. Five stars!

Puts background noise into transmit or receive. Got what I paid for I guess.

The delay on these is like 1 or 2 seconds, which is bad for gaming and like netflix. If you are using it for a music speaker then its perfect.

I have always struggled, trying to find a decent Bluetooth audio transmitter. This product is exactly what I’m looking for usually what I had were big and bulky devices with tons of wires surrounding that could transmit the audio. But this is super sleek. It even has a built-in battery! Now I don’t have to worry about watching TV late at night because I can just plug in my headphones to this device and watch as late as I want.

if you are paying attention to when sounds should be playing in a game or show you'll notice it very easily. it works for me for now, but i'd look for something better if you want less latency.

A must have for any mobile entertainer, for work and in the car. It can transmit or receive Bluetooth music, so you can have it in the car to stream to your radio, or you can pair it with your headphones and listen to the TV without bothering anyone else.This one has an added bonus, an SD card slot. Put some MP3s on a card and insert it into the slot - you have a self-contained audio player for a cocktail reception, audience show load, or just no fuss background music to work to.Micro USB and 1/8" to 1/8" stubby cables included, ready for the car's dashboard!
